Introduce `resumeTest` to complement `pauseTest`?

[trentmwillis]

The current implementation of pauseTest does its job well but it would be nicely complemented by introducing a way to resume the test that gets paused.

One particular use case for wanting this is to encourage developers to enable easier debugging/development against Acceptance tests. It's great to pause a test and try changing some things and then resume the test to ensure the rest of the flow works.

One drawback, however, is that any "resume" function would need to be bound to the global context (window in almost all cases) so that users can easily invoke it from the console.

I know I've seen implementations of this before, but couldn't seem to find any issue pointing to whether or not discussion was had on adding it to the core test helper.

The implementation that I have seen was a gist from @stefanpenner, maybe he still has it handy?

[trentmwillis]

There was also this in the original PR (seems to have gone largely unnoticed): emberjs/ember.js#9383 (comment)

[stefanpenner]

https://gist.github.com/stefanpenner/0baadd08d0733f9e8ae0#file-pause-test-js although that example uses a getter, which may or may not be of value.

[trentmwillis]

Would a PR adding this into core be welcome? If so, I'll pull it together with some tests

I'm not certain how well making a change and resuming will work in practice, but this would be pretty low hanging fruit to add behind a feature flag and experiment with. I'd be +1 to see a PR. :-D

[rwjblue]

Agree

True, but at the very least this will enable the ability to use more than one pauseTest to walk through an Acceptance test (which means I can stop using andThen(() => { debugger; })).

[stefanpenner]

I'm not certain how well making a change and resuming will work in practice,

its less about resuming after a change, and more about being able to emulate debugger, without blocking the entire thread of execution. I can say with confidence this pause/resume works really well with acceptance tests. So +1 from me.

---

This RFC is now entering a "final comment period". This period is intended to focus the community's attention for a final round of consideration and feedback before an RFC is merged.

Please carefully consider the implications of this RFC and how it will affect your Ember projects. Now would be a good time to re-raise any concerns that you feel haven't been fully addressed.

If no significant blockers are raised by October 7, we plan to merge this RFC and make plans for its implementation.

FCP didn't drum up any additional feedback, and we are still 👍 on the feature. Lets do it!
