Encoding and Decoding in Selenium using Base64 Class of Java

What is Base64? Base64 is an encoded scheme that converts binary data in to text format so that encoded textual data can be easily transported over network un-corrupted and without any data loss. Simple Program: package encodeAndDecode; import java.util.Base64; public class EncodeText { public static void main(String[] args) { // TODO Auto-generated method stub String username = "mercury" ; // Encode Username byte [] encodedByte = Base64.getEncoder().encode( username .getBytes()); String encodedText = new String( encodedByte ); System.out.println( "Encoded Username : " + encodedText ); //Decode Username byte [] decodedByte = Base64.getDecoder().decode( encodedByte ); String decodedText = new String( decodedByte ); System.out.println( "Decoded Username : " + decodedText ); } Output: Encoded Username : bWVyY3VyeQ== Decoded Username : mercury Usage In Selenium: We can keep the encoded data ...

Parallel Execution In TestNG Framework Using ThreadLocal Concept

  Parallel Execution We can achieve parallel execution In TestNG Framework by implementing ThreadLocal Concept. We can execute the independent test methods in parallel resulting in reducing the test execution time. BrowserUtility.java This class file contains a methods named by "createDriverInstance" which returns the reference variable of WebDriver Type based on the browser type (chrome or firefox or IE or edge) provided in the parameter. package parallelExecution; import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.chrome.ChromeOptions; import org.openqa.selenium.edge.EdgeDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.firefox.FirefoxOptions; import org.openqa.selenium.ie.InternetExplorerDriver; import org.openqa.selenium.ie.InternetExplorerOptions; public class BrowserUtility { public static WebDriver createDriverInstance(String browserType ) { WebDriver driver = null ;...
