ExpectedConditions in Selenium

How do you usually check that a page is displayed in selenium or not? Most of us would check that the Page Title and the URL is correct:

String expUrl = “https://testersdigest.blogspot.com”;

String expTitle = “My Testing Stories”;

WebDriverWait wait = new WebDriverWait(driver, 15);

wait.until(ExpectedConditions.titleIs(expTitle));

wait.until(ExpectedConditions.urlToBe(expUrl));

First-line here will validate the title check, next one for the URL. But, using the ExpectedConditions class which allows combining the 2 lines we can do it more cleaner:

wait.until(ExpectedConditions.and(ExpectedConditions.urlToBe(expUrl),ExpectedConditions.titleIs(expTitle))); //ExpectedConditions.and() waits until multiple conditions are true.

Not only and() but we also we have or() and not() for ExpectedConditions.

-- wait.until(ExpectedConditions.or(ExpectedConditions.urlToBe(expUrl),ExpectedConditions.titleIs(expTitle))); //waits until at least a condition is true.

-- wait.until(ExpectedConditions.not(ExpectedConditions.urlToBe(expUrl))); //waits until the condition is not true.

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);

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);
