Introduce setupTestAdapter hook

chancancode · chancancode · commit 5d103eee44a5 · 2020-03-30T23:41:00.000-07:00
While working on #1163, we encountered an issue with the test adapter, where unmet expectations (when you set up a `respondTo` for a test that was never triggered) did not cause the offending test to fail. Instead, they became unhandled promise rejections (i.e. "global errors") and fails the _next_ test that runs. This is because we were using the `QUnit.{testStart,testDone}` hooks as if they were a global version of `{before,after}Each`. However, the global hooks are really intended for things like test reporters and runs too late to affect things like the pass or fail status of a test. This commit introduces a `setupTestAdapter` function that uses the normal (not global) APIs so that the failures are attached to the correct test.
