[xwiki-devs] [Idea] Improving component unit testing setup

Hi, Just got an idea: Create an AbstractComponentTestCase implementation that does this in its setup/init() method: - automatically ask the Component Manager for the list of dependencies for the component under test (can be done with a generic for example to know which component class is under test) and for each of them register a mock implementation automatically. The advantages: - remove lots of boilerplate testing code to register mocks of dependent components (all the component descriptor creation) - ensures that top level dependencies are mocked and not deps of deps (best practice) - ensures each component is tested in isolation thus focusing on testing what it does - remove the need for the execution context or configuration source specific inits we have in current AbstractComponentTestCaset implementation - allow to call the annotation loader to register *only* the component under test (and its graph of components) rather than initializing *all* components for each unit test! This will multiply by x100 the speed of our unit tests I believe. WDYT? Thanks -Vincent
