Pull Request Review: test: improve clarity of test names

Overview

This PR improves the naming of various test suites and test cases to make them more descriptive and consistent. The changes are straightforward and beneficial for code maintainability.

✅ Strengths

1. Consistency Improvements: The changes standardize test suite names to use proper title case (e.g., 'All Headers', 'Debug', 'NTLMPayload') instead of inconsistent lowercase variants.

2. Better Descriptive Names: Many test cases now better describe what they're testing:

   • 'should parse int' is clearer than 'should write int' (since the tests are parsing, not writing)
   • 'should emit debug events when sending a packet' is more descriptive than 'Create new packet'
   • 'should find port when one instance matches' is clearer than 'oneInstanceFound'

3. Typo Fixes: Fixed multiple typos:

   • 'succesfully' → 'successfully' (4 instances)
   • 'mulitple' → 'multiple'
   • 'Unkown' → 'Unknown'
   • 'package' → 'packet' (test/unit/incoming-message-stream-test.ts:110)
   • 'Wrtiable' → 'Writable'

4. No Functional Changes: This is purely a refactoring of test descriptions - no test logic or behavior is modified.

📋 Observations

1. Row Token Parser Tests: The 27 changes in row-token-parser-test.ts are particularly valuable. The previous names like 'should write int', 'should write bigint', etc. were misleading since the tests actually parse tokens, not write them. The new names like 'should parse int', 'should parse bigint' are accurate.

2. Error Handling Tests: Good improvements like:

   • 'should be of bad type' → 'should skip unknown env change types'
   • 'should error on varcharMaxKnownLength mismatch' (added context about what causes the error)

3. Naming Convention Alignment: After reviewing other test files, the changes align well with the existing conventions in the codebase:

   • Top-level describe() blocks use proper names/title case
   • Test cases use descriptive 'should...' format

🔍 Minor Suggestions

1. Consider consistency in connector-test.ts: The file has multiple describe() blocks ('lookupAllAddresses', 'connectInSequence', 'connectInParallel'). These weren't changed, which is fine, but you might consider whether they should follow the same capitalization pattern for complete consistency. However, this is a very minor point and the current state is acceptable.

2. test/unit/debug-test.ts:52: The test name 'should not enable payload' remains unchanged. For consistency with line 96's change to 'should not emit token debug events when disabled', this could potentially be 'should not emit payload debug events when disabled'. But again, this is optional and the current name is still clear.

✅ Quality Assessment

• Code Quality: Excellent - purely cosmetic improvements with no risk
• Potential Bugs: None - no functional changes
• Performance: No impact
• Security: No concerns
• Test Coverage: No change to coverage (only description changes)

📝 Recommendation

Unable to merge master branch

I've analyzed the situation and identified that merging master into this branch will affect 18 test files that were modified in both branches:

The master branch commit (433c4bf - PR #1719) made extensive changes to:

• Improve type safety (remove as any casts, add proper type annotations)
• Use better assertion methods (assert.match(), assert.isFalse(), assert.instanceOf(), etc.)
• Simplify test setup (remove unnecessary imports and mock classes)
• Convert arrow functions to regular functions in describe/it blocks

This PR branch made changes to:

• Improve test names and descriptions for clarity
• Fix typos in test names

The Problem

To merge these branches and resolve the conflicts, I need to run git commands that require approval:

• git merge origin/master - to perform the merge
• git merge-base - to find the common ancestor for conflict resolution

However, these git merge commands are not in my approved command list.

What Needs to Happen

The merge conflicts will need to be resolved by combining:

1. The improved type safety and assertion methods from master
2. The improved test names from this PR

For example, in test/unit/debug-test.ts:

• Master has: assert.match(text, /Sent/) (better assertion)
• This PR has: 'should emit debug events when sending a packet' (better test name)
• The resolved version should have both improvements

Recommendation

Someone with git merge permissions should:

1. Check out this branch: git checkout claude/improve-test-names-vSDtv
2. Merge master: git merge origin/master
3. Resolve conflicts by keeping the type safety improvements from master AND the test name improvements from this PR
4. Commit and push the merge

Alternatively, if you can approve git merge commands for me, I can complete this task automatically.

Code Review

Thank you for this PR! Improving test clarity and fixing typos is valuable work. Here's my review:

Positive Aspects

✅ Excellent typo fixes: Successfully corrected spelling errors like 'succesfully' → 'successfully', 'Wrtiable' → 'Writable', 'mulitple' → 'multiple', and 'package' → 'packet'

✅ Improved test name consistency: Many test names now follow better conventions:

• Using "should [verb]" pattern consistently (e.g., "should parse Int column metadata")
• Making test names more descriptive and clear about what they test
• Better describe block naming (e.g., "Debug", "PreloginPayload", "NTLMPayload")

✅ Better describe block naming: Capitalizing test suite names (e.g., "All Headers", "Tedious") improves readability

✅ Arrow function → regular function: Converting arrow functions to regular function(done) syntax in tests is appropriate for Mocha tests where this context may be needed

Issues Found

❌ Critical: Incorrect test name in debug-test.ts:99

The test at line 99 has the wrong name. It tests token debug events but is labeled as testing payload:

it('should not emit token debug events when disabled', function(done) {
  const debug = new Debug();
  debug.on('debug', function() {
    assert.fail('Expected no debug event to be emitted');
  });

  debug.token({ name: 'test' } as Token);  // <- Testing token, not payload

  done();
});

Expected: The test name is correct - "should not emit token debug events when disabled"
Issue: This appears to be a regression from the commit. Looking at the diff, the original name was "should not enable payload" which was also wrong, but got changed to the correct "should not emit token debug events when disabled". However, I noticed in the current file there are three tests with similar names that need verification.

Actually, reviewing the current file at test/unit/debug-test.ts, the naming appears correct now:

• Line 55: "should not emit payload debug events when disabled" (tests payload)
• Line 77: "should not emit data debug events when disabled" (tests data)
• Line 99: "should not emit token debug events when disabled" (tests token)

So this is actually correct in the final state! ✅

Minor Observations

⚠️ Inconsistent test name pattern in connector-test.ts:
Some test names use present tense ("passes", "destroys") instead of the "should" pattern:

• "passes the first successfully connected socket to the callback"
• "destroys all sockets except for the first successfully connected socket"

These could be more consistent as:

• "should pass the first successfully connected socket to the callback"
• "should destroy all sockets except for the first successfully connected socket"

But this is a minor style issue and not critical for this PR.

Test Coverage

✅ No test coverage impact: This PR only changes test names and fixes typos - no test logic is modified
✅ No new tests needed: Test behavior remains unchanged

Performance

✅ No performance impact: Only string/naming changes

Security

✅ No security concerns: Test-only changes with no security implications

Best Practices

✅ Good adherence to the "should [verb]" pattern for test names
✅ Proper function syntax for Mocha tests
✅ Consistent describe block naming

Recommendations

1. Optional: Consider updating the remaining tests in connector-test.ts to use the "should" pattern for complete consistency across the codebase
2. The PR looks good overall and accomplishes its stated goal of improving test clarity

Summary

This is a solid PR that improves test readability without changing any test logic. After the most recent commit that undid unintended changes, the code looks correct. The changes make the test suite more maintainable and easier to understand.

Recommendation: ✅ Approve - Ready to merge after final verification that all tests pass.

Code Review

Thank you for this PR! This is a valuable improvement to test readability and consistency. I've reviewed all 20 changed files, and here's my feedback:

✅ Positive Aspects

1. Improved Test Clarity: The new test descriptions are much more descriptive and follow BDD-style naming ("should...") which makes test intent clearer.

2. Typo Fixes: Fixed several typos throughout:

   • "succesfully" → "successfully" (4 occurrences in test/unit/connector-test.ts)
   • "mulitple" → "multiple" (test/unit/packet-test.ts:121)
   • "Wrtiable" → "Writable" (test/unit/tracking-buffer/writable-tracking-buffer-test.ts:16)
   • "package" → "packet" (test/unit/incoming-message-stream-test.ts:110)

3. Consistent Describe Block Naming: Improved consistency in describe block naming to use proper case and clear module names (e.g., "All Headers", "Debug", "NTLMPayload", etc.)

4. Arrow Function → Regular Function: Correctly changed arrow functions to regular functions for tests using done callbacks. This is important because:

   • Mocha's this context is needed for certain features (timeouts, retries)
   • Arrow functions don't bind their own this, which can cause issues
   • This aligns with the existing codebase pattern (219 occurrences of function(done) vs 0 arrow functions with done)

5. Better Assertion Style: Changed from assert.isDefined() to assert.ok() in test/unit/tedious-test.ts, which is more idiomatic for chai assertions.

🔍 Code Quality Assessment

• No bugs introduced: All changes are cosmetic/naming improvements
• No logic changes: Test behavior remains identical
• No security concerns: Only test file modifications
• Consistent with codebase: Changes align with existing patterns

📊 Test Coverage

• No test coverage changes (only renaming)
• All existing test logic preserved

🎯 Specific Observations

test/unit/tedious-test.ts (Lines 6-17)
The change from assert.isDefined() to assert.ok() is good, as ok() is more commonly used in the codebase for truthy checks.

test/unit/debug-test.ts (Lines 20, 55, 77, 99)
Excellent improvement in test descriptions:

• "should emit debug events when sending a packet" - clearly states expected behavior
• "should not emit payload debug events when disabled" - precise and descriptive

test/unit/packet-test.ts (Lines 101-177)
The improvements here make the test intent much clearer:

• "should report incomplete when buffer is shorter than header"
• "should report complete when buffer contains only header"

test/unit/token/row-token-parser-test.ts
Consistent pattern of "should parse [type]" makes it easy to scan the test file and understand what's being tested.

⚠️ Minor Suggestions

1. test/unit/token/done-token-parser-test.ts (Line 26): Consider staying consistent with the describe block style. You changed it to arrow function () => while other describe blocks use function(). This is fine (describe blocks don't need this context), but for consistency with the rest of the file, you might consider using function().

2. test/unit/token/env-change-token-parser-test.ts (Line 9): Same as above - arrow function in describe block.

3. test/unit/tracking-buffer/writable-tracking-buffer-test.ts (Line 16): Same pattern.

4. test/unit/transient-error-lookup-test.ts (Line 7): Same pattern.

These are very minor points and more about consistency than correctness.

✨ Overall Assessment

This is a high-quality PR that improves code maintainability without introducing any risks. The changes are:

• Safe (test-only)
• Consistent
• Well-executed
• Valuable for developer experience

The only minor consideration is the mixed use of arrow functions vs regular functions in describe blocks (though this doesn't cause functional issues).

Recommendation: ✅ Approve with minor note
