In order to skip test classes regards the state of feature flag we add this listener to our testng configuration
There are 2 ways to annotate that tests required featureFlags to be active :
In method level - with @FeatureTogglingTest on the test method and list of Required Feature flags on
In Class level - with @FeatureTogglingTest on the test class and list of Required Feature flags on
For each test annotation of method level, we check if the test shall whole class shall run regards the features flag test.
Pay attention that this listener shall be configured in the testng.xml (or command line)
It can't be used as Listener annotation of base class
