WHich testing framework is used in Apache Atlas

[#1]

I've imported Apache Atlas code into Eclipse successfully but I don't know how can I run its test cases in order to understand its behaviour. e.g

testRequestUser() in EntityJerseyResourceIT.java class

[#2]

We are using testng within the code base.

From within IntelliJ, it is possible to run the test using Ctrl + Shift + R at the class level.

Hope this helps.
