This adds a regression test for the issue reported in #4278, which doesn't currently occur on main but does occur in the branch associated with #2938 (a PR containing a bunch of changes for fixing bugs with slots).

This regression test will give us a bit more safety as we go to add more slot behavior fixes in the future.

GitHub Issue Number: #4278

What is the new behavior?

Does this introduce a breaking change?

  • Yes
  • No

Testing

Cherry-pick the commit on this branch over the top of #2938 and then confirm that the relevant test fails (due to how the prerender karma tests work what you'll see is actually all tests in that suite failing).

In order to do so you'll need to:

npm run clean && npm i && npm run build && npm run test.karma.prod

(after doing the cherry-pick)

--strictNullChecks error report

Typechecking with --strictNullChecks resulted in 1492 errors on this branch.

That's the same number of errors on main, so at least we're not creating new ones!

Do we ever restore window.console.error anywhere after these tests run? Is that done implicitly by Jest in this scenario somehow (I don't recall if I'm honest).

I refactored the mocking function a little bit to be test-specific by doing the mock and then returning a teardown function to undo it, that way I can make the 'fail on console.error' behavior specific to just the one test I'm adding.

test/karma/test-app/prerender-test/karma.spec.ts Outdated

console.info('console.error', args, err);

Can we use throw here instead? fail is a Jasmine global, and I'd like us to start moving away from those for our future move to Jest 28+

One more clarifying question!

test/karma/test-app/prerender-test/karma.spec.ts Outdated

const testSvg = app.querySelector('test-svg');

Will this get execute if the test fails or throws somewhere between instantiating it and here??

mmm probably not, in which case the test suite is failing anyway, but I can wrap the test in a describe so we can afterAll

test(hydrate): add a regression test for hydrating SVG children
53b543a 
This adds a regression test for the issue reported in #4278, which
doesn't currently occur on `main` but does occur in the branch
associated with #2938 (a PR containing a bunch of changes for fixing
bugs with slots).

This regression test will give us a bit more safety as we go to add more
slot behavior fixes in the future.
