  • Added descriptive names to all workflow steps

All 271 tests passing with no analyzer issues.

Original prompt

This section details on the original issue you should resolve

<issue_title>Add tests for luthor generator</issue_title>
<issue_description>Currently, luthor_generator does not have any tests. We should write tests, either using build_test or alternatively, simpler tests by using fixtures and testing the generated API by using .having, etc.</issue_description>

...

Fixed in commit b52e0c9. All files formatted, dpk run analyze passes with no issues, and all 271 tests passing. Changes made:

  • Fixed import ordering
  • Added helper to only use raw strings when needed (for regex with backslashes)
  • Suppressed @jsonkey annotation warning on freezed params
  • Fixed dynamic call warnings
  • Regenerated example and test fixture files

You're correct - reverted to auto_apply: dependents in commit b8e1267. The targets section ensures the builder still runs on test fixtures while keeping the proper production setting.

The change to auto_apply: all_packages was unintentional. Reverted to dependents
which is the correct setting for production use. The targets section ensures the
builder still runs on test fixtures when needed.

All 271 tests passing, no analyzer issues.

Added "Setup project" name to the step in commit d984f2c.

…orkflow

- Add explicit builder configuration in targets section to enable luthor generator
  to run on its own test fixtures even with auto_apply: dependents
- Refactor CI workflow to use 'dpk run build' instead of direct build_runner command
- Step now has proper name: "Build generator test fixtures"

This fixes the CI error where luthor generator wasn't running on test fixtures.
All 271 tests passing, no analyzer issues.

Added "Setup project" name to the setup-luthor action step in the unit tests workflow
for better readability and clarity in CI logs.
