get Min Granularity
Returns the minimum granularity of the events to be logged. Typically, 0 corresponds to events from the Gradle-generated test suite for the whole test run, 1 corresponds to the Gradle-generated test suite for a particular test JVM, 2 corresponds to a test class, and 3 corresponds to a test method. These values may extend higher if user-defined suites or parameterized test methods are executed. Events from levels lower than the specified granularity will be ignored.
The default granularity is -1, which specifies that test events from only the most granular level should be logged. In other words, if a test method is not parameterized, only events from the test method will be logged and events from the test class and lower will be ignored. On the other hand, if a test method is parameterized, then events from the iterations of that test method will be logged and events from the test method and lower will be ignored.
Return
