When a test fails in a module, gradle stops the build (which is probably fine). I don't know if the order of the modules to test is specified but locally I can see controls tests run before graphics tests. When there's something broken in graphics (scenegraph for instance), the controls tests are likely to fail and the developer will have to spend time figuring out the error is actually down in graphics. I'm particularly interested in these two modules, but in general, we should try to define testing order from the bottom layers up.
