How To Use Breakpoints For Debugging In Selenium WebDriver |
https://dev.to/shalinibaskaran12/how-to-use-breakpoints-for-debugging-in-selenium-webdriver-28ln
|
How To Use Breakpoints For Debugging In Selenium WebDriverAutomation testing is not always a smooth ride There are cases where the tests would not work as expected in which cases debugging the test code or implementation is the only way out Debugging issues in tests become even more difficult if the test suite comprises a large number of test methods Like me many QA engineers would co relate to this situation when performing Selenium automation testing There could be cases where we need to understand the memory allocation of the objects which cannot be physically seen from the outside Though the call stack might help in such scenarios digging deeper into the internals of the test code and or the automation framework would be super beneficial In all the above scenarios the process of debugging the code comes into the picture As an automation engineer our end goal is to ensure that Selenium WebDriver scripts are executed in the best possible time However debugging in Selenium WebDriver is a useful method that should be leveraged effectively whenever there are not to evident issues in the test code We can debug Selenium WebDriver in Eclipse IDE when we are executing the test scripts Breaking the normal code flow by inserting breakpoints at strategic points can be used for debugging issues in the test code In this blog we deep dive into the essentials of debugging in Selenium WebDriver from a test automation point of view We would also look at how to debug Selenium WebDriver in Eclipse and IntelliJ the two popular IDEs for Selenium Java development What Is Debugging For starters debugging is a scrutinized process that involves a deep understanding and minute examination of the source code For example the code might have failed or there is a need to take a deep dive into the framework code to understand execution steps in a much better way I would term this as a major perk of working with an open source framework like Selenium The process of debugging involves four main stages namely identify isolate fix and review In the first stage of debugging we have to identify and understand the issue or failure in the code This would help us to perform root cause analysis which is one of the key skills of a tester or developer If one has identified the issue and understood its root cause it would be easier to develop an approach to resolve the issue In the second stage we have to isolate the portion of the code on which debugging has to be performed However it is not necessary to debug every line of code unless required Therefore we have to separate the faulty code into smaller chunks and perform debugging Then by understanding the cause of the failure a fix can be provided to the faulty code which can be finally reviewed and merged Of course it has to be fixed and reviewed so that it doesn t break the other parts of the code Now let s see how to debug Selenium WebDriver in Eclipse with our testing framework which consists of tests written using Selenium WebDriver and Java What are Breakpoints in Selenium WebDriverAkin to software breakpoints the breakpoints in Selenium WebDriver let us temporarily pause or stop the execution of the code Once the execution is stopped you can verify the essential elements of the source code When debugging in Selenium WebDriver breakpoints should be inserted at appropriate places so that the required variable values and other details can be checked in detail Whether you are using the Eclipse IDE or IntelliJ IDE breakpoints are shown alongside the UI How To Debug Selenium WebDriver In EclipseThere are multiple ways to debug the code having a code walkthrough getting support from peers refactoring and restructuring etc Debugging is often considered the easiest and most efficient way to debug the issue in the code Several IDEs for web development provide the option of running the code and inserting breakpoints to debug the source code Since the steps involved in debugging mode look similar in most of the IDEs you can use the IDE as per your requirements Before running the tests in Eclipse IDE set breakpoints at appropriate locations in the source code Breakpoint is usually a point where the code has to be stopped for further examination or understanding while debugging It is usually inserted in front of a single line or multiple lines in the code By setting or inserting a breakpoint the code will be executed up to the breakpoint and the execution will halt once the breakpoint is encountered The breakpoint can be inserted into a single line or multiple lines of code a method and even a class Let us see how to insert a breakpoint in Eclipse IDE for debugging in Selenium WebDriver Inserting BreakpointsTo add a breakpoint in your code you can follow either of the below ways Double click in the left side marginPerform a right click in the left side margin and click the Toggle Breakpoint option Move to the line where you need to add the breakpoint and then press CTRL SHIFT B Move to the line where you need to insert the breakpoint click the Run menu and click the Toggle Breakpoint option This way you can add multiple breakpoints in your code Once the breakpoint is added you will see a blue circle on the left margin where you tried to insert the breakpoint Now that the breakpoint is added to the source code it s time to debug the issue Before running the code we have to switch to Debug perspective To do this navigate to the Windows menu →Perspective →Open Perspective Here choose the Debug option To run the code you have toSelect the Java class which has to be run in debug mode Next right click on the class move to Debug As an option and click Java Application Within the class workspace you can right click select Debug As →Java Application Click the Run menu Navigate to Debug As option and then click Java Application You could also use the shortcut icon to run the code Click the debug shortcut icon and then move to Debug As →Java Application You can also use Keyboard shortcut keys to run the code in debug mode Press ALT SHIFT D You will see a small popup on the screen like belowPress J to select Debug Java Application and enter the debug mode If you haven t switched to the debug perspective view before running the code you will get a switch notification prompting you to switch to the Debug perspective before running the code Click Switch Now the code starts running in debug mode The code will be executed and it stops when it reaches the line where the breakpoint has been added For example in my code I have added breakpoints in lines and So while running the code the execution stops at line as it is the first breakpoint in the code and then moves ahead one by one When the breakpoint has been reached it will be highlighted as shown in the below screenshot Once the execution starts you could see a window that shows the variables breakpoints and expressions tab The Breakpoints tab shows the lines in which the breakpoint has been added For example this shows that the breakpoint has been added in lines and in the Java class brokenLinksCount The Variables tab shows the values being assigned to the variables in the line where the breakpoint has been added To control the execution we have various shortcut keys in the editor You could see them under the Run menu You can also view them in the submenu bar Let us understand their usage in more detail Step Into F The line where the breakpoint has been added will be executed followed by the next lines For example if the breakpoint has been added to a method then the control reaches inside the method and debugs the code written within that method Sometimes the control might reach deep into the libraries and JDK classes which could be skipped by checking the Use Step Filters option Step Over F When the control reaches the method where the breakpoint has been added it steps to the next line after the method without getting into the method Step Return F The control returns to the caller of the method once the breakpoint inserted in the method is executed Resume F The code is executed until the control reaches the next breakpointTerminate CTRL F This is used to terminate the debugging or execution of the code forcibly Skip All Breakpoint CTRL ALT B This is used to skip all the breakpoints inserted in the code How to remove the inserted breakpoints Either of the following ways can remove the breakpoints added in the code A simple way to remove the added breakpoint is by double clicking on the same point where it was added Right click on the breakpoint and click Disable Breakpoint option A breakpoint can also be removed by pressing SHIFT double click on the breakpointThe other option is by navigating to the Run menu →Remove All Breakpoints to remove all the breakpoints inserted in the code So far we have seen the process of debugging in Selenium WebDriver by adding breakpoints in Eclipse The idea of debugging seems to be almost the same across different IDEs How To Debug Selenium WebDriver In IntelliJTo add breakpoints in IntelliJ you can choose either of the following ways namely Double click the left margin of the line in which the breakpoint has to be added Move to the line in which the breakpoint has to be added Then navigate to Run menu →Toggle Breakpoint →click Line Breakpoint Once the breakpoint has been added you can see a red circle on the left margin Similarly you can also add a method breakpoint to debug the methods in the framework Running The Code In Debug modeNow we can begin to debug the code in our framework Right click on the class and click Debug You can also run in the debug mode by clicking the Debug option under the Run menu You can also click the Debug icon on the top right side of the editor After clicking the debug option you will see various options to control the execution under the Run menu Once it reaches the breakpoints and executes the code you can see tick marks on the breakpoints To terminate the debug mode click the red square icon or the Stop option under the Run menu Now you would have got a clear picture of the similarity of the debugging process in different editors Let us understand an example for debugging in Selenium WebDriver Below is the code which was used for demonstrating debugging in Selenium WebDriver import java io IOException import java net HttpURLConnection import java net MalformedURLException import java net URL import java util ArrayList import java util List import org openqa selenium By import org openqa selenium WebDriver import org openqa selenium WebElement import org openqa selenium chrome ChromeDriver import org openqa selenium support ui ExpectedConditions import org openqa selenium support ui WebDriverWait public class brokenLinksCount public static void main String args throws MalformedURLException IOException String username user name String access key access key WebDriver driver null DesiredCapabilities capabilities new DesiredCapabilities capabilities setCapability build Java Finding broken links on a webpage using Selenium capabilities setCapability name Java Finding

openConnection connection connect URL url connection getURL System out println url toString int response code connection getResponseCode System out println activeList get j getText connection disconnect driver close The above implementation is used to find broken links using Selenium WebDriver As demonstrated earlier we added breakpoints at appropriate places in the test code Also the tests are run on a cloud based Selenium Grid provided by LambdaTest Porting existing implementation from a local Selenium Grid to a cloud Grid requires minimal effort and also lets you reap benefits offered by parallel testing in Selenium Adding breakpoints at different points in the code will help us understand how each link in the website works and analyze the HTTP response code of each and every link thereby understanding which link is broken In addition we can add breakpoints in for loops for debugging purposes if any link is broken and get to know the failure by getting the response code of the link Using breakpoints in the debugging mode helps analyze issues and fix the failure in the automation framework Wrapping Up Debugging in Selenium WebDriver is the art of understanding the code flow in a framework analyzing the issue and fixing the faulty parts in the test code In this blog we deep dived into the importance of debugging in Selenium WebDriver for Selenium automation testing We also looked at debugging in Selenium WebDriver using Eclipse and IntelliJ IDEs I hope you have gained good knowledge in the process of debugging in Selenium WebDriver Now it s time to add breakpoints in your code and run them in debug mode to understand this process clearly Happy debugging |

DevOps Simplified for beginners DevOps So you have been following the buzz around the internet about the term DevOps but don t exactly know what DevOps is or maybe you are someone who s trying to determine if DevOps is a career for you Then this is the blog for you I once was at that stage when I had a hard time starting my learning journey in DevOps So this blog is dedicated to all students complete beginners and whoever is willing to explore In this blog we willMake ourselves comfortable with the term DevOps Understand Software Development Life CycleDiscuss the significance of DevOpsImplementing DevOps a study of the structure and tools used Look at basics to get started with your DevOps journey IntroductionFirstly DevOps is neither a tool nor a software nor a programming language it s not even a technology stack To put it simply DevOps is just a philosophy or a mindset An ideology that makes Software development Life Cycle SDLC aka Application lifecycle management efficient reliable and agile The term DevOps is itself derived from two major phases of Software development Life Cycle those are Development and Operations DevOps DEVelopment OPeration S DevOps is the mixture of cultural philosophies practices and tools that aim towards delivering quality applications and services at a high rate It s a culture that distributes the workload as well as collaboration among various teams in an organization to achieve a common goal of developing and managing the application for the end user ScenarioTypically in a mid size organization two teams handle the Software development Life Cycle Development TeamOperations teamBoth the teams are extremely essential in the Software development Life Cycle and both the teams are dependent on each other Development The development team develops the project or application right from the scratch adds new features and prepares a usable product for the end user Operations The operations team tests the application and provides the development team feedback on the same the product may go into the development phase again When the final product is ready the operations team deploys the application for the end user Era before DevOpsLet s first understand the term Software development Life Cycle The software development life cycle SDLC is the process used by the software industry to design develop and test software or applications It consists of phases which include developing the software from scratch to delivering it to the end user There are various methods of going through the SDLC ーDevOps being one of them we will discuss two widely used methods that gave birth to the DevOps method Understanding these two methods is crucial as it plays an important role in understanding the DevOps culture Waterfall ModelThis is a linear approach of SDLC suitable for small scale static projects Requirements ー gt Analysis ー gt Design ー gt Development Code ー gt Test ー gt Deploy ー gt MaintenanceRequirements Coordinating with the client and understanding their demands and getting a clear picture of the desired product This phase answers WHAT is the productAnalysis It s time to analyze the requirement and specify the technology stacks tools languages etc will be used in this project HOW to develop this product This phase also includes structuring further processes and setting up goals and timelines for the project Design In this phase the developers start developing the project Create mock ups design User Interface and make a prototype of the end product Development Code The developers start coding This phase ends when the developers have prepared the product as decided in the previous phases now ready to test this product Testing This phase now shifts the SDLC towards the operations team The team tests the product check for any bugs or loose ends The team also makes sure that the product aligns with the client s demands Deploy Once the product is all set to enter the market it is deployed by the operations team The product is open to use for the end user Maintenance Dealing with the issues that occur in the client environment Patches are released to fix these problems Releasing improved and better versions to improve the product Drawbacks of the Waterfall MethodologyOnce your application is in the testing phase it s very difficult to go back and change something that wasn t well thought out in the Analysis phase There is no actual functioning product till the later stages of the life cycle have been completed This is not an efficient model for complex object oriented and Dynamic projects Intense planning and scoping required in the early stages that consumes a lot of time and resources The waterfall methodology is unsuitable for projects with shifting goals or requirements For example the application your team is developing is aimed at desktop users and is now in the testing phase Perhaps the market has transformed and the client now demands a mobile friendly solution too This disruption in the objective may cause the entire life cycle to restart The Waterfall Model may prove to be costly as any point of failure at any stage of the SDLC can lead to a restart of the entire life cycle This was the typical SDLC approach which required a lot of fixing And so a new method was being observed to replace the waterfall method Agile ModelThis methodology patches up the shortcoming of the Waterfall methodology The Agile Method introduces an iterative approach Design ー gt Development Code ー gt Test follows an iteration until the result is achieved The team understands the requirements of the client Analyze and plan to achieve the goal Now begins the loop of Design Code Test repeat These iterations take between weeks each iteration is executed quickly thus providing the actual product in the early stages Unlike the waterfall approach that provides the actual product at the end of the cycle At the end of each iteration after testing the product the product is developed and tested With every iteration the product keeps getting feature rich and stable This cycle continues till the final product is now feature rich and is perfect to fulfil the end user demands The problem The problem arises between the Final Testing phase and The Deployment phase These errors are usually regarding the dependencies For eg The application may be developed in Java version and the operations team has set up the environment for Java version The conversation between the Development Team and the Operations team goes like this ーOperations team The application looks good upon testing it just doesn t work after deployment Development team It works on our PCs so you may need to configure your environment right or try to duplicate our development environment environment in which we produced the application Operations team You need to specify what are the dependencies of your application so we can set up the deployment environment and make it The key breakpoints here are the communication and collaboration between the two teams Here the environment refers to the Operating System the tools and packages required to run the application It s very important to make sure that the deployment environment matches the development environment to ensure the proper functioning of the application in the deployed state Deployment simply means that the application is live and up and running on the internet or in the desired environment for example ーThe client s machine Say you made a portfolio website on your local machine using HTML CSS and JS to make that website visible on the internet you host your website you upload all your HTML CSS and JS files on a server that will host your website on the internet This uploading of data on a server and making sure that the website is up and running this process can be referred to as the deployment of your website Deployment was a manual and tedious process in both Waterfall methodology and Agile methodology Now these problems gave the inevitable birth to a new advanced and efficient model of SDLC which today is popularized as DevOps DevOps MethodologyDevOps is a methodology aimed at efficiency and convenience in SDLC with the help of the use of modern techniques tools and systematic practices DevOps is more about how you architect your SDLC so that you can get maximum output It is a Continuous loop where all the phases are intended to be executed seamlessly represent as shown in the figure Image Courtesy Dynatrace News Start with the DevOpsDevOps revolves around four phases In the subsequent blog we will discuss each of these processes in detail Version Control Version control saves a lot of time and resources The developed code is deployed on a shared online repository on a shared folder online collaborationMaintaining a log of all the changes made by the developers in the source code This makes bug tracing very efficient and identifying lines of code is responsible for the errors and bugs Version control is keeping a track ofWho made the changes When were the changes made What were the changes Previous versions of the code Tools used Git GitHub GitLabContinuous Integration Now that the code is ready with additions and patches it s time to build and test those changes in a standard environment this is a manual and time consuming process Jenkins is one of those tools that help you automate and speed up this process Jenkins is an open source server that lets you set up an ideal environment for your application it automatically fetches the code from the repository integrates it with the existing source code and re builds the application to check for errors After testing and integration Jenkins creates an executable file war jar etc These packages are now ready to be deployed on a server to make the application live Continuous Delivery Jenkins now deploys this package on a live test server for User Acceptance Test UAT This is the final testing this check the overall functioning of the application as it will be perceived by the end user Continuous Deployment This is the final phase the application is now hosted on the production server the application is now up and running live for the end users Tech Stacks requiredA beginner level knowledge of application Development preferably Object Orient languages such as Java C Python A beginner level knowledge of Computer Networking as DevOps is deeply integrated with services that run on the internet Syllabus of CompTIA Network A medium level knowledge of Cloud Infrastructure as Cloud is the pillar of DevOps we will discuss more Cloud Technology in the upcoming blogs A medium level knowledge of UNIX Linux commands A medium to advance level knowledge of some tools we will discuss in further blogs ConclusionDevOps is a vast field that requires knowledge from various domains due to its deep integration in every aspect of the Software Development Lifecycle DevOps is not only concerned with tools and technology it also looks over collaboration empathy innovation growth mindset and effective cross cultural communication What s next This is the first blog of the DevOps Simplified series In the upcoming blogs we will study each phase of the DevOps Model starting with Version Control In the subsequent blogs we will also look at the tools used in each of the phases of DevOps including Docker and Kubernetes and how they contribute to the Software Development Lifecycle I will also be sharing free resources that helped me on my journey to DevOps Feel free to ask any questions any feedback would be greatly appreciated |

Moving from JavaScript to TypeScript |
https://dev.to/andrewbaisden/moving-from-javascript-to-typescript-40ac
|
Moving from JavaScript to TypeScript IntroductionI have been a JavaScript developer for many years and I did not really have much intention to go outside of my technical stack There is a lot of safety in sticking with what you already know and trying to learn too many programming languages can be daunting I told myself JavaScript is already pretty time consuming to learn and nobody truly masters it because the API keeps getting updated along with the documentation as the language evolves There are also a lot of frameworks and libraries to learn It was outdated thinking and fortunately I saw the light when I was between jobs looking for work Companies were looking for polyglot developers which essentially means a person who knows and is able to use several programming languages Expand your knowledgeThat is when I realised that JavaScript was not enough if you really want to stand out then you need to be capable of using different programming languages So back then I decided to learn TypeScript and Python Ironically I actually managed to get a job but the company only required me to use JavaScript so unfortunately I forgot most of the TypeScript and Python that I learned because I was just not using it on a daily basis All of this happened before I was active on tech Twitter and before I started blogging so I really did not understand the concept of building in public and working on side projects My justification was that I already had a job so I did not need to do programming on weekends too Finding work during the pandemicFast forward to and everything changed We were now in our second year of this global pandemic living with Covid It took me about months to get a decent job offer and I have been working at this company ever since During this period I have worked on projects that had a Python and Kotlin backend So I was getting exposed to different languages JavaScript is still one of the most popular programming languages in the world and is always going to be in high demand It came top in the Stackoverflow Survey whereas TypeScript is ranked number So if JavaScript is so popular and highly sought after around the world why bother learning TypeScript Why you should learn TypeScriptAs good as JavaScript is the language still has many flaws when compared to other modern programming languages And unfortunately there are a lot of people out there who just straight up don t like JavaScript for various reasons TypeScript is basically a modern way to develop JavaScript projects and the language compiles to raw JavaScript so your codebase can still be read by a browser and other developers who might not know TypeScript Honestly the syntax is JavaScript so even if you are not familiar with TypeScript you can still understand what is happening TypeScript aims to solve a lot of the problems that JavaScript has which makes the language a lot closer to other modern programming languages In my opinion anyone who hates JavaScript is likely to fall in love with TypeScript Or at the very least find less reasons to complain about it JavaScript vs TypeScriptThere are quite a lot of differences between the two I will cover some of them here Compilation errorsTypeScript is able to flag errors in compile time during the development process This is a really good feature because it means that you are less likely to have errors at runtime when your app has been built and is running JavaScript is only capable of seeing these errors at runtime so you are highly likely to have much slower debugging because you are now doing more unnecessary checking The better tooling available in TypeScript provides a far better experience when writing code Static typing vs Dynamic typingJavaScript uses dynamic typing whereas TypeScript uses static typing With dynamic typing you can reassign variables because the data type can change This is not possible with static typing because the data type is defined meaning that if you try to assign a different data type it will show a compile error There are pros and cons for each method This is valid JavaScript codelet num num You will get the error Type string is not assignable to type number let num number num Describing your data using an interfaceTypeScript can use an interface in the code which pretty much describes the structure of an object in the application It defines the overall syntax that is required for the object so you can use it for documentation and issue tracking inside of your code editor It is worth noting that the TypeScript compiler wont convert the interface syntax to JavaScript It is only used for type checking also known as duck typing or structural subtyping Describe the shape of objects in your code interface Series id number seriesName string releaseDate number Use the interface for type checking in your object const series Series The id needs to be a numberid The series name needs to be a stringseriesName The Book of Boba Fett The release data needs to be a numberreleaseDate console log series CommonJS modules vs ES modulesNode js uses CommonJS modules by default and anyone who is familiar with it will know about the require syntax In comparison when you use Node js with TypeScript you have the option to use either require or import and export statements Of course there are ways to get it working in native JavaScript too if you do your research JavaScript CommonJS modulesconst express require express TypeScript ES modulesimport express from express When using TypeScript you get access to a tsconfig json file which lets you change lots of settings which include the target This lets you set the JavaScript language version for outputted JavaScript files For example they can be ES ES ES etc TypeScript DrawbacksTypeScript is pretty amazing but it does have a few disadvantages that you should be aware of Firstly TypeScript does not work in the browser so you have to compile your code to JavaScript before you can use it Fortunately TypeScript has a compiler so when you have got it setup it will automatically compile your TypeScript files to JavaScript and luckily it is a fast process So you don t have to worry about having to wait around for minutes for your code to compile the process is usually done in seconds Another disadvantage is the fact that you are going to be writing a bit more code especially if you want to have static type checking I don t really see this as a downside though because you are writing more performant and better code which is going to make it more maintainable Something else that you need to know is that you will require some Type Declaration packages alongside some of the normal packages that you use Type Declaration packages describe built in objects Declaration files give you a way to declare types or values so there is no need to provide any sort of implementations for the values This is not always going to be the case because some packages already have type definitions but not all of them It is easier to understand in this Express Node js example below JavaScript Express Appnpm i expressconst express require express const app express app get req res gt res send Home Route const port process env PORT app listen port gt console log Server running on port port http localhost port TypeScript Express Appnpm i express types express types nodeimport express Response Request from express const app express app get req Request res Response gt res send Home Route const port process env PORT app listen port gt console log Server running on port port http localhost port TypeScript SupportTypeScript is well supported and if your code editor of choice is Visual Studio Code then TypeScript is treated like a first class citizen because Microsoft developed the code editor and the language Pretty much all of the popular JavaScript frameworks support TypeScript too So that includes React Angular Vue and Svelte The framework express js also has compatibility with TypeScript as do other Node js frameworks So there really is nothing stopping you from using TypeScript on the front end and back end of your application Another advantage is the fact that you can now use ES modules on the back end and front end natively So if you are creating an app with a Node back end and a React front end for example You can now use import and export statements for both and you don t need to use CommonJS modules require statements anymore How to learn TypeScriptI learned TypeScript from Scrimba and I also followed another good TypeScript course on Udemy If you already know JavaScript then it won t take you long to get up to speed with TypeScript Also if you are new to JavaScript or still learning the basics then it is better for you to wait until you have more experience with it before learning TypeScript Learn Typescript for freeUnderstanding TypeScript Edition |
