Why all API enthusiasts should know about GraphQL?

With GraphQL, what you queried is what you get, nothing more and nothing less. It is easy to use as it has a JSON like syntax and also provides lots of performance benefits. Here's a query for the Star Wars API: https://swapi.apis.guru/graphiql query{ allFilms { films { id title episodeID } } } This query returns the id, title, and episodeID of the 6 original Star Wars movies. Now consider that there are 2 vendors that are consuming this API and one of them wants id, title, and episodeID and the other one wants the only id, and title but NOT the episodeID. Now without GraphQL, we would have created 2 versions of this API i.e. the first one with the id, title, and episodeID in the response and the second version giving a response with id and title only. Isn't it a headache to maintain so many versions if you have different requests from various vendors that are consuming your APIs? That's where a GraphQL is a real lifesaver. Please check graphQLComplete method shown in the below image where we are getting all 3 data points i.e. id, title, and episodeID requested by the 1st vendor and graphQLPartial method which returns the id, and title as requested by the 2nd vendor. restAssured api apitesting automation graphQL

How to Unzip files in Selenium (Java)?

1) Using Java (Lengthy way) : Create a utility and use it:>> import java.io.BufferedOutputStream; import org.openqa.selenium.io.Zip; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipInputStream;   public class UnzipUtil {     private static final int BUFFER_SIZE = 4096;     public void unzip (String zipFilePath, String destDirectory) throws IOException {         File destDir = new File(destDirectory);         if (!destDir.exists()) {             destDir.mkdir();         }         ZipInputStream zipIn = new ZipInputStream(new FileInputStream(zipFilePath));         ZipEntry entry = zipIn.getNextEntry();         // to iterates over entries in the zip folder         while (entry != null) {             String filePath = destDirectory + File.separator + entry.getName();             if (!entry.isDirectory()) {                 extractFile (zipIn, filePath);

Encode/Decode the variable/response using Postman itself

We get a lot of use cases where we may have to implement Base64 encoding and/or decoding while building our APIs. And, if you are wondering if it is possible to encode/decode the variable/response using Postman itself or how to encode/decode the token or password in postman and save it in a variable? To Base64 encode/decode, the quickest way is to use JavaScript methods btoa, atob: atob - It turns base64-encoded ASCII data back to binary. btoa - It turns binary data to base64-encoded ASCII. Sample code : var responseBody = pm.response.json(); var parsedPwd = JSON.parse(atob(responseBody.password)); // presuming password is in the payload pm.collectionVariables.set("password", parsedPwd);

The use of Verbose attribute in testNG or POM.xml (maven-surefire-plugin)

At times, we see some weird behavior in your testNG execution and feel that the information displayed is insufficient and would like to see more details. At other times, the output on the console is too verbose and we may want to only see the errors. This is where a verbose attribute can help you- it is used to define the amount of logging to be performed on the console. The verbosity level is 0 to 10, where 10 is most detailed. Once you set it to 10, you'll see that console output will contain information regarding the tests, methods, and listeners, etc. <suite name="Suite" thread-count="5" verbose="10"> Note* You can specify -1 and this will put TestNG in debug mode. The default level is 0. Alternatively, you can set the verbose level through attribute in "maven-surefire-plugin" in pom.xml, as shown in the image. #testNG #automationTesting #verbose # #testAutomation
