Backend test setup

[reginaldbondoc]

• Initial test configuration
• Sample test (just the healthcheck endpoint for now)
• Moved things from index.ts to separate parts for easier test setup
• Initial coverage configuration
• GH Action workflow
  • Modified Backend PR check to run test
  • New workflow to post comment/report of test result and coverage to PR (Note: this new workflow will not successfully run until merged into target main branch)

Sample:

Test result:

Coverage annotations:

Note: some files were automatically modified by prettier on commit (husky?).

For code coverage, will the missed branch or line be shown to the user? I'm curious how they can know what has caused the coverge to fail

Yes:

(But the link there just points to commit, not actual file/line in GitHub). But this shall provide proper feedback on which line/branch is not covered.

Will be the tests only available to run in GH CI/CD or is it possible to run test locally? Example npm run test:backend

Possible to run test locally. Dev can do: npm test

Lastly, i didn't see a coverge threshold defined unless there is a default? https://jestjs.io/docs/configuration#coveragethreshold-object

@dangtony98 can you also review the index.ts file to make sure you are up to date with the new restructure?

[Zamion101]

There are some questions I'm curious about. Overall not seeing any major security or design flaw. There needs to be more work on some parts towards consistent type definition and error handling. I will be working on central error handling but first I need this PR to be merged into main for me to start working on some changes.

That's correct. Because there's no test yet, aside from the initial one that I added. If we define the threshold, the run will fail. 😉

For now, I plan to just start with this, and add more tests as we move forward. Once we reach 50%, I would suggest we set the threshold and then aim higher. 👍

That's consistent with my rationale of opening this PR as early as now 👍

I'm okay with current state of this code. Waiting for your review @dangtony98
