How can we run test cases in parallel using TestNG?

Hey Tom,

To execute test cases parallely using TestNG, incorporate the following key-value pairs within your test suite configuration:

  • parallel=ā€œmethods/tests/classesā€: This attribute specifies the level of parallelism at which the tests should run. You can choose to parallelize at the method, test, or class level based on your requirements.

  • thread-count=ā€œ{number of threads}ā€: This attribute defines the maximum number of threads that TestNG should use to execute your tests concurrently. Adjust the value according to the desired level of parallelism.

Hereā€™s an example configuration snippet for a TestNG suite named ā€œArtOfTestingSuiteā€ running methods in parallel with a thread count of 5:

<suite name="ArtOfTestingSuite" parallel="methods" thread-count="5">
    <!-- Add your test, class, and method configurations here -->
</suite>

This configuration ensures that TestNG executes the specified methods concurrently using five threads. Customize the suite, test, class, and method configurations within the <suite> tag according to your testing requirements. This parallel execution strategy can significantly reduce test execution time and enhance overall efficiency in your testing process.
