Can anybody give me a step by step tutorial on how can I run parallel test with TestNG.
The core reason of using TestNG is the ability to run tests in parallel. Which means you can run tests simultaneously. With the help of TestNG XML you can create multiple test cases and run them together. Using annotations we can write multiple test cases and TestNG XML just simplifies the task!
