Enhanced test coverage for updateAgentMetadata refactoring

[continue-development-app]

Summary

This PR adds comprehensive enhanced test coverage against PR #9289 to improve the test suite for the updateAgentMetadata refactoring introduced in PR #9285.

Test Improvements

New Test Categories Added (90+ new tests):

1. Concurrency and Race Conditions (3 tests)

• Multiple simultaneous metadata updates
• Interleaved isComplete true/false calls
• Slow git diff with fast metadata posting

2. Boundary Value Testing (6 tests)

• Very large history arrays (10,000 items)
• Very large diff stats (999,999 additions/deletions)
• Very small token costs (0.000001)
• Maximum precision cost rounding
• Zero values in all fields

3. Complex State Transitions (3 tests)

• Transition from no data to complete with data
• Summary changing between calls
• Diff stats changing between calls

4. Error Recovery Scenarios (3 tests)

• Recovery from git diff timeout
• All collectors failing gracefully
• Partial collector failures

5. Cache Token Details Handling (3 tests)

• Only cachedTokens when cacheWriteTokens is 0
• Only cacheWriteTokens when cachedTokens is 0
• Undefined promptTokensDetails

Enhanced Helper Function Tests:

calculateDiffStats (20+ tests)

• Basic functionality with additions/deletions
• Metadata line filtering (file headers, hunk headers, diff metadata, binary markers)
• Edge cases (multiple files, very large diffs, mixed line endings)
• Real-world scenarios (refactoring, adding files, deleting files)
• Special code patterns (++ and -- operators)

extractSummary (25+ tests)

• Basic functionality (extraction, role filtering, whitespace trimming)
• Truncation behavior (custom maxLength, exact boundaries)
• Role filtering (user, system, assistant messages)
• Content type handling (string, object, array content)
• Edge cases (very long conversations, undefined content, empty messages)

getAgentIdFromArgs (13+ tests)

• Basic functionality (flag parsing, multiple flags)
• Edge cases (empty argv, empty/whitespace values, UUID format, special characters)
• Real-world scenarios (typical CLI invocations)

Benefits

1. Better Coverage: Tests now cover edge cases and error scenarios that weren't tested before
2. Concurrency Safety: Validates that concurrent metadata updates work correctly
3. Robustness: Ensures error handling works properly in all failure scenarios
4. Real-world Testing: Includes tests based on actual usage patterns
5. Documentation: Tests serve as documentation for expected behavior

Testing

All existing tests pass, and the new tests validate:

• Backward compatibility is maintained
• Error handling is graceful
• Concurrent updates work correctly
• Boundary conditions are handled properly
• Helper functions work as expected

Summary by cubic

Adds 90+ tests for updateAgentMetadata and its helpers to harden behavior under concurrency, edge cases, and failures. Covers large diffs/histories, state transitions, error recovery, and token cache details; existing tests remain passing.

• Dependencies
  • Bumped @aws-sdk/client-bedrock-runtime and @aws-sdk/credential-providers to ^3.931.0 in the CLI lockfile.

^{Written for commit c872e80. Summary will update automatically on new commits.}

Reviewed PR #9291 for documentation needs. ✅

This PR adds comprehensive test coverage for internal CLI metadata collection utilities (, , , ). These are implementation details not exposed in user-facing documentation.

No documentation updates required because:

• Only test coverage improvements for existing internal functions
• No new user-facing features or APIs
• No changes to CLI commands or agent behavior from a user perspective
• Functions under test are internal utilities, not documented interfaces

The enhanced test coverage will help ensure reliability of the metadata collection system without impacting user-facing documentation.
