Code Review

This pull request migrates the test suite from using standard package:test assertions to the package:checks library. It adds checks as a dev dependency, updates test imports to use package:test/scaffolding.dart and package:checks/checks.dart, and rewrites the assertions across several test files to use the new check API. There are no review comments, and I have no feedback to provide.

This pull request migrates the test suite from using standard expect assertions to the package:checks library. It adds checks to the development dependencies in pubspec.yaml and updates the assertions across several test files (command_test.dart, dhttpd_test.dart, ensure_build_test.dart, and utils_test.dart) to use the new check API. There are no review comments, and I have no feedback to provide.

Code Review

This pull request migrates the test suite from using standard package:test assertions (expect) to the modern package:checks library. It adds checks as a dev dependency in pubspec.yaml and updates imports and assertions across multiple test files, including command_test.dart, dhttpd_test.dart, ensure_build_test.dart, and utils_test.dart. I have no feedback to provide as there are no review comments.
