How can you perform parallel testing using TestNG?

Performing Parallel Testing Using TestNG

In TestNG, parallel testing can be implemented to execute test cases concurrently which helps in reducing overall execution time and improving efficiency. To perform parallel testing using TestNG, you can follow these steps:

1. Define the test suite in the testng.xml file.
2. Specify the parallel attribute in the suite tag with the desired mode of parallel execution (methods, classes, tests).
3. Ensure that your tests are thread-safe and can run in parallel without interfering with each other.
4. Run the testng.xml file using TestNG to execute the tests in parallel mode.

By implementing parallel testing using TestNG, you can significantly reduce the time taken to execute test cases and accelerate the overall testing process.

Remember to follow these steps carefully to ensure successful parallel testing using TestNG.
