TestNG - Parallel Test

 TestNG allows the tests to run in parallel or multi-threaded mode. This means that based on the test suite configuration, different threads are started simultaneously and the test methods are executed in them. This gives a user a lot of advantages over normal execution, mainly reduction in execution time and ability to verify a multi-threaded code.

 In this post we will create two testng file as 
TestParallelClassOne and TestParallelClassTwo and each containing two methods i.e test case one and test cases two and each test will open different url in firefox browser. 

TestParallelClassOne




TestParallelClassTwo as 

Now create testng.xml file as 

 

Right click and run as Testng suite. 

If we see the output each test is running on different thread.
