What is the best way to login to multiple tc without logging in for each tc
You just need to create a test case to log in, don’t put
WebUI.closeBrowser() at the end of that test case. And then you can run other test cases on the browser opened by the log in test case.
It’s hard to say anything more than this since I don’t know the particularities. If you want more help then please articulate your problem along with what you’ve tried.
