Adapter pattern in TypeScript |
https://dev.to/jmalvarez/adapter-pattern-in-typescript-2ffl

Adapter pattern in TypeScript IntroductionThe adapter pattern also known as the Wrapper pattern is a structural design pattern that allows your code to communicate with other interfaces that are initially incompatible This pattern is great to use when you need to integrate third party libraries that you can t change or when you need to integrate legacy code that you can t change Imagine that your application works using strings However you need to integrate a third party library that works with JSON objects that contain the strings that you need You can t change the library s code but you can apply the adapter pattern to transform those JSON objects into strings to make them compatible with your application Following this example if you later had to integrate a new third party library that was using a different format for example XML you could create a new adapter to make it compatible with your application in a easy way Another advantage of this pattern is that your code is decoupled from external libraries This means that you can replace the library that you are using or add new ones without having to change your code ImplementationAs an example I m going to build an application that gets books data from third party libraries My app works using a concrete data type but the third party libraries use different types I m going to use the adapter pattern to make them compatible with my application You can find the full example source code here Declare an interface for the adapters of the third party libraries This will be the interface used by your application The adapter will implement this interface and will be responsible for transforming the data from the third party library into the format that your application uses In the example I m going to define a method to get the books data and I m going to also specify the structure of the data that the method will return which is the data structure that my application works with interface LibraryAdapter getBooks title string author string Initially I m going to integrate a third party library that returns the books data in the CSV format This is the code of the third party library class LibraryCSV getBooks const books title Book author Author title Book author Author title Book author Author return title author r n books map book gt book title book author join r n The next step is to create the adapter for the third party library This adapter will implement the interface defined in the previous step and will be responsible for transforming the data from the CSV format to the format that my application uses class LibraryCSVAdapter implements LibraryAdapter private library LibraryCSV constructor library LibraryCSV this library library getBooks const books this library getBooks const booksArray books split r n const booksData booksArray slice return booksData map book gt const bookData book split return title bookData author bookData Now we can already use the adapter with our application const library new LibraryCSV const libraryAdapter new LibraryCSVAdapter library console log libraryAdapter getBooks Output title Book author Author title Book author Author title Book author Author If I wanted to integrate a new third party library it would be as easy as defining a new adapter for the new library For example I m going to integrate a library which returns the data in a stringified JSON format This would be the library code class LibraryJSON getBooks const books title Book author Author title Book author Author title Book author Author return JSON stringify books And this would be my adapter class LibraryJSONAdapter implements LibraryAdapter private library LibraryJSON constructor library LibraryJSON this library library getBooks const books this library getBooks return JSON parse books And this is how I would use the new adapter with my application const libraryJSON new LibraryJSON const libraryJSONAdapter new LibraryJSONAdapter libraryJSON console log libraryJSONAdapter getBooks Output title Book author Author title Book author Author title Book author Author Notice that I didn t have to change my existing application code to integrate the new library I just had to create a new adapter for the new library and use it ResourcesExample source codeAdapter refactoring guru |

WHY IS COMPATIBILITY TESTING MUCH NEEDED FOR CUSTOMER-FOCUSED TESTING? |
https://dev.to/codewithmmak/why-is-compatibility-testing-much-needed-for-customer-focused-testing-2nfp
|
WHY IS COMPATIBILITY TESTING MUCH NEEDED FOR CUSTOMER FOCUSED TESTING WHAT IS COMPATIBILITY Compatibility is the ability to check if two entities can work together without actually modifying or altering them Let s see some of the real life examples to better understand if my feet size is UK can I wear UK size shoes if Windows requires a minimum of GB RAM can I still install it on a lower RAM configuration can I install a Mac installer on a Windows machine WHAT IS COMPATIBILITY TESTING Compatibility testing is a type of Non functional testing It majorly focuses on the support or compatibility of applications to ensure there is no difference in behaviour look and feel etc It gives great flexibility to my customer to use the application in different modes There are several analytics tools which can give you a clear idea of how the application is used and where your target audience is located and how they are accessing your application etc It helps in serving customer needs TYPE OF COMPATIBILITY TESTINGThe following are the type of compatibility testing types Browsers It checks the compatibility of test applications on different browser combinations such as Google Chrome Mozilla Firefox Safari Internet Explorer Microsoft Edge Opera etc Devices It checks the compatibility of your software with different devices like different ports like USB Printers Scanners Other media and Bluetooth Operating systems It checks your software to be compatible with different Operating Systems like Windows Mac OS Linux Unix etc Network It checks your software to be compatible with different network speeds and bandwidth Mobile It checks your software is compatible with different mobile platforms like Android iOS Trizon OS etc Version It checks your software is compatible with a different version of the software or even a hardware combination Software It checks your software is compatible with other software and doesn t cause hindrances for each other TOOLS FOR COMPATIBILITY TESTINGEarlier when there was no cloud solution at that time compatibility testing used to be done by setting up devices and platform with different OS and browser combination and later point of time some of the cost of the setting of physical machines were taken care of by Virtual Machines Thanks to the cloud solution which takes care of setting up an environment for you You just need to select the different combinations of OS and browser combinations and you are good to start testing just like tossing a coin in the air Some of the most commonly used compatibility testing tools are as follows LambdaTestBrowserStackSauceLabsAWS Device FarmCOMPATIBILITY TESTING MATRIXWhile doing customer focus testing it is required to have a list of browsers and devices which is being anticipated to be most used by the customer and compatibility of developed applications should be maintained across the different combinations The table below represents a sample browser compatibility testing matrix COMPATIBILITY TESTING APPROACHGathering Functional amp Non Functional RequirementAsk for a compatibility testing matrix with this you will understand customer focus In some cases it can work the other way round and you can propose the compatibility testing matrix with all the combinations you can think of Ask for a test bed if it s available or else you can suggest a cloud solution like LambdaTest Analyse the requirement and prepare the test scenarios Perform functional testing and make sure the application is stable and the majority of bugs are resolved Perform non functional testing which is compatibility testing on the configuration which is agreed upon with the client Prepare a Compatibility testing report which clearly states the bugs which occurred on a different configuration Once all the bugs found in compatibility testing once fixed and verified make sure to run another round of compatibility testing to ensure there are no regression bugs Finally make sure to sign off and produce the test closure report COMMON COMPATIBILITY TESTING DEFECTSEven though modern development frameworks these days claim to be completely responsive on all devices but still many times bugs slip through the cracks The compatibility testing bugs are generally user interface issues which are as follows Web elements alignment issues Web elements overlapping issues Font size issues Broken frames or rendering issues Look and feel issues |
