A test class named `RunMyTest.java` will be run, but a test called `CheckSomething.java` will not be. This was done because gradle's built-in scanner for test classes was buggy in earlier versions of gradle. It seems to have been fixed in the gradle 3.x time frame from what I can tell.

Attempting to execute utility classes without test methods (meaning without at least one method annotated with `@Test`) or `abstract` classes (whether or not there are any test methods) will fail.

This means that a class with no test methods that subclasses an abstract class with `@Test` methods will be run correctly.

Looks good to me, verified that tests in files which are not suffixed with `Test` get executed now.
buildSrc/build.gradle file also has the code that we are changing here,
scanForTestClasses = false
include "**/*Test.*"
I think it won't affect as there are no tests there.
