Test parallelism with IntelliJ and TestNG

Question

I\'m attempting to run some TestNG tests in parallel but don\'t have access to a testng.xml as IntelliJ builds it on the fly. I\'ve tried adding parameters such as \'parallel=m

Answer 1

It appears that you would be able to use the JDK Settings tab to specify "vm parameters", and then specify the parameters like so: -parallel methods -threadcount 2

However, IntelliJ actually creates an XML file and then uses that when running TestNG. That XML file has parallel="none" inside of it. As a result, the XML configuration 'wins' and you do not get the parallelization you are looking for.

There doesn't appear to be an easy way to adjust the contents of that default XML file, at least in terms of the parallelization options. You may just be stuck with creating XML suites yourself.
