We are temporarily pinning to `ubuntu-20.04` instead of `ubuntu-latest`. `mono_repo` does not support anything than `ubuntu-latest`, so the change are being made manually and the self validate step is being...

Currently if a web test causes the browser page to crash (like a memory leak causing an OOM error) then we'll report the test as "did not complete", but it's...

We disallow imports to `dart:io` in our production toolchains: webdev, bazel. We currently allow imports in flutter, and when running web tests, with runtime failures instead. To avoid surprises -...

Use devtools in place of Observatory UI

`fail` API may not cause a test to fail if it's running in a zone with an uncaught async error handler

1

Since `fail` is `throw TestFailure` we can get into a situation where an async failing `expect` call in some error handling zone will not result in a test failure. https://github.com/dart-lang/test/blob/e0be5ec076c59d621de1892b108727f560f217bc/pkgs/test_api/lib/src/expect/expect.dart#L109...

Adding a static type makes the API easier to use correctly. The call site can easily inline the `Uri.parse` if necessary.

Frame.caller() is broken inside `Chain.capture`

5

The VM started giving us different, significantly truncated `StackTrace` instances when running in the zone for `Chain.capture`. `Frame.caller()` relies on parsing `StackTrace.current` which no longer contains the caller we were...

Remove unused Chain.disable functionality

I cannot find any uses of the `Chain.disable` API outside of the tests in this package. It is unnecessary complexity. Removing the functionality may also remove some of the overhead...

The doc comment has been misleading, likely since the `when` argument was introduced. There is some nuance to how the argument interacts with the presence of the `onError` argument that...
