Review Checklist

Hello reviewers! 👋 Please follow this checklist when reviewing this Pull Request.

General

  • Ensure that the Pull Request has a descriptive title.
  • Ensure there is a link to an issue (except for internal cleanup and flaky test fixes), new features should have an RFC that documents use cases and test cases.

Tests

  • Bug fixes should have at least one unit or end-to-end test, enhancement and new features should have a sufficient number of tests.

Documentation

  • Apply the release notes (needs details) label if users need to know about this change.
  • New features should be documented.
  • There should be some code comments as to why things are implemented the way they are.
  • There should be a comment at the top of each new or modified test to explain what the test does.

New flags

  • Is this flag really necessary?
  • Flag names must be clear and intuitive, use dashes (-), and have a clear help text.

If a workflow is added or modified:

  • Each item in Jobs should be named in order to mark it as required.
  • If the workflow needs to be marked as required, the maintainer team must be notified.

Backward compatibility

  • Protobuf changes should be wire-compatible.
  • Changes to _vt tables and RPCs need to be backward compatible.
  • RPC changes should be compatible with vitess-operator
  • If a flag is removed, then it should also be removed from vitess-operator and arewefastyet, if used there.
  • vtctl command output order should be stable and awk-able.

why do we need to mutate the global flagset to do these tests? from my reading we should be able to do our assertions with testFlagSet directly

The function PreventGlogVFlagFromClobberingVersionFlagShorthand uses f := goflag.Lookup("v"), so we need to register v flag in goflag.CommandLine for this.

The function Parse has fs.AddGoFlagSet(goflag.CommandLine), to test this we first register a testFlag in goflag.CommandLine, then to check if this was called, we use testFlagSet.Lookup. Please let me know if I am missing something here.

i'm not sure we need this, as we exercise this function in a bunch of end-to-end tests implicitly (cc @rohit-nayak-ps)

I think the aim here is to increase unit test coverage, so it is fine to add these, especially since we don't yet have the tooling to incorporate the test coverage from e2e tests into our Code Coverage CI workflow.
