Description

I am using TestNG with Gradle to run functional tests in parallel with
Selenium Grid. I was getting this error while trying to execute two
test classes in parallel.

Initially I didn't know what was going on. Later I noticed two methods
in each class had same name. When I changed the name of one of the
methods(that had same name as in other class) in one class, the tests
ran in parallel without any error.

It has to be problem with either Gradle or TestNG. It should be able to handle same method names in two different classes.

GRADLE-1532 Fixed the issue with TestNG parallel tests. The problem was caused because method name was used to identify the test id. When someone used TestNG's feature @Test(invocationCount = 2, threadPoolSize = 2) then just the method name was not enough for identification. My fix is using the ITestResult from TestNG as an identifier for internal use in a hashmap. Also I did very simple refactoring that should help in debugging similar issues in future.
