Not getting up only in testng but working on java main method then it working fine

@BeforeMethod should be run.

Answer 1

If the same code works in the main method, but doesn't work in the TestNG @BeforeMethod, then most likely the @BeforeMethod wasn't executed.

You can try to set a breakpoint to any line of the setup() method and run your code in the debug mode to see if the method gets called.
Alternatively, you can add some logger or a simple System.out.println("") statement somewhere in the method.

If the @BeforeMethod didn't run, check the following things:

• Make sure that at least one @Test exists and gets executed by the TestNG
• In case the setup() method is located in a separate class (e.g. some BaseTest class), check that that class is added to your testNG .XML file. Or check that your actual 'Test' class extends the 'BaseTest' class.
• Ensure that no other @Before* hooks were failed. You can add 'alwaysRun = true' (@BeforeMethod(alwaysRun = true)) to make sure that your @BeforeMethod will be executed even if some other hooks were skipped or failed.
