fix(cli): not to show 1 test when no tests are in the file

[ChihweiLHBird]

This is to fix an issue that caused wing test against an empty some_file_name.w file shows Tests 1 passed (1).

See the issue #5852 for details.

Solution:
Instead of adding a dummy pass message, the function now returns early with a predefined message when there's no test case to avoid confusion later.

And I don't think it would need full E2E tests?

I am still exploring how to add test for this new test system behavior. Will mark the PR as ready after adding/updating test for it.

Checklist

• Title matches Winglang's style guide
• Description explains motivation and solution
• Tests added (always)

@ChihweiLHBird thanks for this! Do you mind adding a few more details in the description on the bug itself and how this will look like after the fix?

[ChihweiLHBird]

Hi @eladb, thanks for the suggestion! This is just a draft PR and I will mark it as ready after adding those things.

Let me know if you have any feedback or anything, for example whether this is the right way to fix it, thanks! ^_^

Hey @eladb @Chriscbr, I think this PR is ready for reviews. And the CI reported a rate limiting error, should we try a re-run?

[eladb]

@ChihweiLHBird let us know if you need any help

@eladb Does it look good to you? Or any suggestion?

❌ Unstable Self-Mutation ❌

Self-mutation has run twice in a row. There may be a something non-deterministic in the build or test process.
Check the last mutation commit (97eca6a) for suspicious changes.
This is typically caused by:

• Absolute paths
• Timestamps
• Random values
• Flakey tests (relying on one of the above)
