Dart 单元测试无法在 Github 上运行

Question

I have a dart project with unit tests. When I run the unit tests locally they run successfully.

I added CI to the project with Github Actions. The same unit tests that run successfully locally, fail on Github Actions with the following error:

00:00 +0: loading test/foo_test.dart
00:01 +0: loading test/foo_test.dart
00:01 +0 -1: loading test/foo_test.dart [E]

foo_test.dart imports foo.dart as a package (not relative path).

import 'package:foo/foo.dart'

Answer 1

The issue was caused due to me renaming the package name in pubspec.yaml and not updating the import in the test file.

pubspec.yaml:

name: foo_bar # <---- this was renamed from 'foo' to 'foo_bar'
description: An example dart project
version: 1.0.0

...

Either reverting the name change or updating the import to import package:foo_bar/foo.dart fixed the issue on Github Actions.

The weird thing is that regardless of the rename, the tests still ran successfully locally, which makes me think this might be a caching bug.
