Generator test-case expected-update #38
Description
The code generator is tested using "golden/expected" files - verifying the generated code matches the expected code exactly. While this is a great way to make sure the code doesn't change unexpectedly and there are no regressions, it poses a challenge when actually changing the generator code (as a developer).
To achieve a good developer experience, the test-cases expected code should be updatable by calling a single command. For example, in Go, tests are normally called as go test tests/generator while there's an option to update the .expected files calling go test tests/generator -update.
After the files are updated, it's up to the developer to verify the changes are correct (by manually reviewing them), before committing the code to git.
