Defining the scope of our End to End tests


We all should try that our End to End test should NOT considerably reiterate the test efforts of our Unit test and API test. Ideally, our end to end should be meant to confirm that user(s) can use our app in the way it's intended to do so, perform interactions with it without hitting any issues and always work when performing any E2E transaction(s). On the other hand, our Unit and API test should test and cover business logic. 

Many a time, we go overboard to reach 100% coverage, create an automated mess in terms of freezing a scope of our End to End tests and we might reach to a point:
- Where our test source code becomes even the same or in fact, more than the application codebase
- And/Or automation execution run time is likely to take the same time as it takes to write the test case, etc.

There's no silver bullet here and it's all about trying, failing and finally succeeding. One such approach can be:
Divide your test cases broadly into two major groups: Fat and Thin. Your Fat test cases should be what a max number of users performs repeatedly on your application. First target these and spend your max energy, effort and time on these because if these aren't working- as Russell Peters said- Somebody Gonna Get Hurt Real Bad.

Then only jump to Thin cases. What are Thin cases? These are those cases where users use our application mostly in an unexpected and unforeseen way but again as these can create issues in your app these are also important but obviously, these take a second priority. 

Based on the execution test time allowed (on our final test cycle) and regression impact, QE can recommend running both Fat and Thin tests (recommended) OR only Fat ones on the last cycle. 

P.S. As part of our daily CI/CD test automation run, we should try to run both Fat and Thin tests.

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 (en...

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

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);
