海外TECH	DEV Community	Solving Advent of Code Puzzles in Idiomatic Kotlin	https://dev.to/kotlin/solving-advent-of-code-puzzles-in-idiomatic-kotlin-1m62	Solving Advent of Code Puzzles in Idiomatic KotlinWhat s the best way to learn a language other than writing some code with it Solving fun and short tasks like the ones from Advent of Code might be a great opportunity to practice your language skills and you can learn a lot if you compare your solutions with how others have solved the same problem Lots of developers from around the world including some from the Kotlin team take part in the Advent of Code challenges created by Eric Wastl Advent of Code is a series of tasks published every December which you solve and compete with others Many would agree that it s the best advent calendar to celebrate Christmas and New Year To help the community learn idiomatic Kotlin and motivate more developers to solve Advent of Code tasks in Kotlin in the future we decided to prepare solutions for the tasks from Advent of Code It doesn t matter if you solved it back in December you re ready to solve it now or you just want to check the solutions we hope you ll find something useful in these materials Of course it works best if you try to solve the same task first yourself Below is the solution and video for the first task If you find this format useful and want us to cover more tasks in a similar fashion please share in the comments Day Report RepairWe re fixing an expense report Find the full task description at You need to find the two and in the second part three entries from the list of numbers that sum to and then multiply those two or three numbers together How to solve the taskRegister at open the task at write your solution in Kotlin and check the result on the site You can either write Kotlin code online or using an IDE download the free Community Edition of IntelliJ IDEAcreate a Kotlin projectwrite your solution thereFinally compare your solution with the solution below We marked the src folder as a source set to put the code directly there We copied input files like src day input txt to the source folder for convenience You can find the solutions in this project SolutionHere s the sample input First we need to read and parse the input We can use the Kotlin readLines function for reading a list of lines from a given file File src day input txt readLines The readLines returns a list of Strings and we convert it to a list of numbers import java io Filefun main val numbers File src day input txt readLines map String toInt You put this code inside the main function the entry point for your program When you start typing IntelliJ IDEA imports the java io File automatically Now we can simply iterate through the list and then for each number repeat the iteration and check the sum for first in numbers for second in numbers if first second println first second return You put this code inside main so return returns from main when the required numbers are found In a similar way you check the sum of three numbers for first in numbers for second in numbers for third in numbers if first second third println first second third return You can run it and get the result for a given input That s it The first task is really a simple one However we iterate over the same list again and again for each of the elements Having two nested loops for finding two numbers makes it N operations where N is the number of elements When we need to find three numbers that s three nested loops and N operations If the list of numbers is large that s not the most efficient way to solve this type of problem Surely there is a better way right There definitely is and the Kotlin standard library can help us express that concisely As often happens we can replace the long calculation with some kind of smart storage used to find the result Solving the task for two numbersFirst let s build a map for number “complements numbers that together with the given number sum up to val complements numbers associateBy it We use the Kotlin associateBy function to build the map Its lambda argument returns a key in this map by which the list element is getting stored For the sample input it ll be the following map numbers complements map After this procedure you can clearly see the answer The very first number from the list is present in the complements map as a key which means it s the complement for the number and they sum to Having stored this information in a map we can check if any number from the list has a complement in this map The following code finds the first number with an existing complement val pair numbers mapNotNull number gt val complement complements number if complement null Pair number complement else null firstOrNull We transform each number into a pair consisting of the number and its complement if the complement exists and then find the first non null result We use mapNotNull which transforms each element in a list and filters out all the resulting nulls It s shorthand for calling first map and then filterNotNull on the result firstOrNull returns the first element in the list or null if the list is empty Kotlin standard library often uses the OrNull suffix to mark functions returning null on failure rather than throwing an exception like elementAtOrNull singleOrNull or maxOrNull Starting with Kotlin you can also replace the two consequent operations mapNotNull and first OrNull with one function call firstNotNullOf OrNull After building the auxiliary structure we managed to find the resulting two numbers in N operations not in N as before We need a multiplication of these numbers so here s the last step println pair let a b gt a b The pair variable contains a nullable Pair of two numbers and is null if the initial list contains no numbers that sum up to We use safe access together with the let function and destructuring in a lambda syntax to display the result in case pair is not null Solving the task for three numbersThe next step is solving this problem for three numbers Let s reuse what we ve done so far and extract the logic of finding a pair of numbers summing up to a given number into a separate function fun List lt Int gt findPairOfSum sum Int Pair lt Int Int gt Map sum x gt x val complements associateBy sum it return firstNotNullOfOrNull number gt val complement complements number if complement null Pair number complement else null We also used the firstNotNullOfOrNull function Now we use findPairOfSum to build a helper map that stores the complement pair of values for each number which together with this number sums up to Map x gt y z where y z xval complementPairs Map lt Int Pair lt Int Int gt gt numbers associateWith numbers findPairOfSum it For the same initial input here s the complement pairs map numbers complement pairs null null null As before you already can see the answer It s the number that corresponds to a non null pair in a map However we don t really need to build the whole map ーwe only need to find the first number that corresponds to a non null pair Let s find it using the already familiar firstNotNullOfOrNull function fun List lt Int gt findTripleOfSum Triple lt Int Int Int gt firstNotNullOfOrNull x gt findPairOfSum x let pair gt Triple x pair first pair second Note Kotlin s concise syntax the function can return an expression directly The final step is to find the multiplication if the resulting triple is non null similar to how we did it before println triple let x y z gt x y z That s all In the next part we ll discuss how to solve the second task Please let us know if you find this content useful and would like us to provide solutions for more tasks Used with the permission of Advent of Code Eric Wastl	2021-07-15

海外TECH	DEV Community	Different Types Of Automated Tests	https://dev.to/woodjessica/different-types-of-automated-tests-384l	Different Types Of Automated TestsIn the software testing domain automated testing has catapulted to new heights There are many organizations that clearly understand the sheer power of automated testing These organizations know how test automation can benefit them immensely in their software development projects in the form of reduced costs improved efficiency and enhanced quality of the software application In this article you will get to know about the different types of automated tests What is automated testing It is a testing process where automation tools are used to test and control the execution of test cases Then the actual test results are compared with the expected test results Following are the different types of automated tests API tests It is possible for software to talk to other software applications through the medium of an Application Programming Interface API Just like any other software is tested there is a need to test APIs as well The compliance functionality and security issues are tested In the case of web applications request and response of an application can be tested to ascertain whether they are encrypted and secure or not One of the popular tools for API testing is SOAP UI which comes in both free and paid versions You can use other tools depending upon your specific needs Unit tests To test the code level automated unit tests are written Bugs are identified in methods functions and routines There are some organizations that are interested to perform unit testing through their own developers while other organizations go with the idea of hiring test automation experts The source code can be accessed by these experts who will in turn write unit tests to break the production code In the case of unit tests whenever the compilation of code takes place all the unit tests are being run in order to ascertain whether all the functionalities are working properly or not If any of the unit tests doesn t function properly or fails then there are chances of bug or bugs present in the production code GUI tests In this type of automated test the user interface of the application is being tested There is change taking place every now and then in the GUI s How the users will use the application will also be carefully scrutinized Users take the support of mouse and keyboard and thus mimicking the same behavior by using the mouse and keyboard to write or click to objects present on the user interface is done by automated GUI tests Due to the above mentioned scenario bugs can be found at an early stage and then it can be used in many scenarios such as filling up forms or regression testing Smoke tests After any build is given out of the application smoke tests are executed immediately to ensure that the application is functioning properly It is considered to be a small test suite and is considered to be executed a few times depending upon the test scenario Regression tests This type of test is performed on a new module to ensure that all the existing modules have not been affected by it After each new iteration of testing this test is repeated After a new iteration the main test cases stay fixed with a few new additions Regression tests are almost frequently run by the testing teams Conclusion If you are looking forward for a deeper know how on the efficacy of the different types of automated tests then do get connected with a premium software testing services company who will take you through the entire process of the test automation framework About the author I am a technical content writer focused on writing technology specific articles I strive to provide well researched information on the leading market savvy technologies	2021-07-15 12:24:34
