Code Review
This pull request significantly improves test coverage for writeSkillOutput and fileSystemReadFileTool, which is a great addition. The new tests cover a good range of success and error scenarios. My review includes a few suggestions to enhance the new tests for better efficiency and robustness. I've identified some redundant function calls within the tests and a potential test-pollution issue that could affect test reliability. Addressing these points will further strengthen your test suite.

PR Review: test(skill,mcp): improve test coverage for writeSkillOutput and fileSystemReadFileToolSummaryThis PR improves test coverage from 89.81% to 90.28% by adding comprehensive tests for Code QualityPositive observations:
Minor Suggestions1. fileSystemReadFileTool.test.ts - Mock import pattern The current approach imports after vi.mock('../../../src/core/security/workers/securityCheckWorker.js', () => ({...}));
import { runSecretLint } from '../../../src/core/security/workers/securityCheckWorker.js';This works due to hoisting, but for clarity, consider grouping all imports at the top with explicit 2. writeSkillOutput.test.ts - Duplicate assertions in error tests Tests for EPERM and generic errors call await expect(writeSkillOutput(...)).rejects.toThrow(RepomixError);
await expect(writeSkillOutput(...)).rejects.toThrow(/Permission denied/);Consider combining into a single call with a try-catch for more efficient testing: await expect(writeSkillOutput(...)).rejects.toThrow(
expect.objectContaining({
message: expect.stringMatching(/Permission denied/)
})
);However, the current approach is clearer about what's being tested, so this is a stylistic preference. Potential IssuesNo critical issues found. The tests correctly mock dependencies and verify expected behaviors. Premortem AnalysisPotential failure scenarios and mitigations
Edge cases not covered (optional future enhancements):
These are minor and don't block this PR. Verdict✅ LGTM - This is a clean, focused PR that improves test coverage without introducing risks. The tests are well-written and follow project conventions. 🤖 Review by Claude Code |

165-194: Consider consolidating duplicate test invocations.Similar to the EPERM test, this test invokes
writeSkillOutputtwice with identical mocks. See the suggestion for lines 108-138 for a consolidated approach.

108-138: Consider consolidating duplicate test invocations.The test invokes
writeSkillOutputtwice with identical mocks—once to check the error type and again to check the message. This can be consolidated using a single invocation with chained assertions.Apply this diff:
- await expect( - writeSkillOutput(output, skillDir, { - mkdir: mockMkdir as unknown as typeof import('node:fs/promises').mkdir, - writeFile: mockWriteFile as unknown as typeof import('node:fs/promises').writeFile, - }), - ).rejects.toThrow(RepomixError); - - await expect( + const promise = writeSkillOutput(output, skillDir, { + mkdir: mockMkdir as unknown as typeof import('node:fs/promises').mkdir, + writeFile: mockWriteFile as unknown as typeof import('node:fs/promises').writeFile, + }); + + await expect(promise).rejects.toThrow(RepomixError); + await expect(promise).rejects.toThrow(/Permission denied/); + });Note: Remove the second
writeSkillOutputcall (lines 132-137) since both assertions can be applied to the same promise.

tests/core/skill/writeSkillOutput.test.ts (2)
79-106: LGTM!The test correctly validates that
tech-stack.mdis written whentechStackis provided in the output references.
196-217: LGTM!The test correctly validates that non-Error objects are handled and rethrown as
RepomixError.tests/mcp/tools/fileSystemReadFileTool.test.ts (6)
1-1: LGTM!The changes to use the default export from
node:fs/promisesand the addition of security check worker mocks properly enable testing of file reading with security validation scenarios.Also applies to: 8-21
31-31: LGTM!Using
clearAllMocks()is correct here since it preserves the mock implementations defined invi.mock()while clearing call history between tests.
82-107: LGTM!The test correctly validates that directory paths are rejected with an appropriate error message directing users to the correct tool.
109-142: LGTM!The test thoroughly validates the successful file read path, including all metadata fields and both text and structured content formats.
178-195: LGTM!The test correctly validates that general errors during file operations are caught and returned with appropriate error messages.
197-214: LGTM!The test correctly validates that non-Error objects are handled gracefully with appropriate error messages.
…ystemReadFileTool Add comprehensive tests to increase code coverage from 89.81% to 90.28%: writeSkillOutput.ts (63.88% → 100%): - Add test for techStack file writing - Add tests for EPERM/EACCES error handling - Add test for generic error handling - Add test for non-Error object handling fileSystemReadFileTool.ts (62.5% → 100%): - Add test for directory path error - Add test for successful file reading - Add test for security check failure - Add test for general errors during file reading - Add test for non-Error object handling

PR Review: test(skill,mcp): improve test coverage for writeSkillOutput and fileSystemReadFileToolSummaryGood PR that improves test coverage from 89.81% to 90.36% by adding comprehensive tests for error handling in Code Quality AssessmentStrengths:
Issue:
|
| Risk | Likelihood | Mitigation |
|---|---|---|
| Mock hoisting issues | Low | ✅ Handled - vi.mock() is hoisted correctly |
| Test isolation/shared state | Low | ✅ beforeEach clears mocks between tests |
| Flaky tests | Low | Tests are deterministic with mocked I/O |
Not covered (acceptable for unit tests):
writeSkillOutput: Error duringmkdiroperation (onlywriteFileerrors tested)fileSystemReadFileTool: Binary file handling, symlinks
These edge cases are acceptable to leave for integration tests.
Verdict
✅ LGTM - This is a clean, focused PR that improves test coverage without introducing risks. Ready to merge.
