End-to-End Test Performance Enhancements

[xWink]

Currently, running the full e2e test suite takes roughly 50 minutes on my Macbook Pro. This is a consequence of the fact that each test typically takes 1-2 minutes, and we have a large number of tests.

As new e2e tests are added, coverage increases, but test runtime does too.

Possible ways we can improve performance of e2e tests (more ways likely exist):

• Create reconciler unit tests to replace some e2e tests
• Parallelization of e2e tests
• Conglomeration of individual tests to a single test in order to avoid multiple executions of beforeEach/afterEach

Note that this is partially addressed by #510, this removed most blockers that were impacting parallel execution. We may need to adjust a few timings and retries to make this reliable. In the meantime, early adopters can try:
