@Isolatedis used to declare that the annotated test class should be executed in isolation from other test classes.
When a test class is run in isolation, no other test class is executed concurrently. This can be used to enable parallel test execution for the entire test suite while running some tests in isolation (e.g. if they modify some global resource).
