Adding playground link when a test fails

[nofar9792]

Describe the feature you'd like:

The playground link is really useful.
Each time find/get function fails, it prints a really long HTML.
Maybe you can add the playground link by default, each time

1. find/get function fails
2. One of the expect fails. like expect(element).toBeChecked();

Suggested implementation:

1. Adding the link to getElementError.
2. I would like to hear what do you think

I think that's a pretty good idea personally. Maybe it could be disabled globally?

[AlonMiz]

That sounds like a great idea.

It sounds good to me too, it could be very useful but I agree with @kentcdodds that should be disabled globally.

[kentcdodds]

To be clear, I think it should be enabled by default. Just something you can disable globally.

Also, to be clear further, anyone can claim this. Feel free to volunteer to implement this :)

Ooo sounds neat.
I'd definitely wan't this in my pipeline.

Aren't the expects standalone, and don't relate to any testing lib?
How can we put the the link in that case without binding jest-dom to testing-library?
