An update to the JooUnit framework allows defining asynchronous tests in simpler syntax. A test method may now return a Promise<void> to signal that it is waiting for asynchronous calls to finish. For that, the convenient async / await syntax may be used. This replaces the cumbersome JooUnit TestCase.addAsync() method and makes test code much more readable.

Instead of inheriting from AbstractCapRestTest, tests that mock REST calls now use the new, more consistent and comprehensive utility functions from @coremedia/studio-client.client-core-test-helper and @coremedia/studio-client.cap-rest-client-test-helper.
