Ismo Vuorinen	00044ce374	refactor: enhance testing infrastructure with property-based tests and documentation (#147) ... * feat: implement property-based testing with gopter Add comprehensive property-based testing infrastructure to verify mathematical properties and invariants of critical code paths. **Property Tests Added:** - String manipulation properties (normalization, cleaning, formatting) - Permission merging properties (idempotency, YAML precedence) - Uses statement formatting properties (structure, @ symbol presence) - URL parsing properties (org/repo extraction, empty input handling) **Mutation Tests Created:** - Permission parsing mutation resistance tests - Version validation mutation resistance tests - String/URL parsing mutation resistance tests Note: Mutation tests currently disabled due to go-mutesting compatibility issues with Go 1.25+. Test code is complete and ready for execution when tool compatibility is resolved. **Infrastructure Updates:** - Add gopter dependency for property-based testing - Create Makefile targets for property tests - Update CI workflow to run property tests - Add test-quick target for rapid iteration - Update CLAUDE.md with advanced testing documentation **Test Results:** - All unit tests passing (411 test cases across 12 packages) - All property tests passing (5 test suites, 100+ random inputs each) - Test coverage: 73.9% overall (above 72% threshold) * fix: improve version cleaning property test to verify trimming Address code review feedback: The 'non-v content is preserved' property test now properly verifies that CleanVersionString itself trims whitespace, rather than pre-trimming the input before testing. Changes: - Pass raw content directly to CleanVersionString (not pre-trimmed) - Assert result == strings.TrimSpace(content) to verify trimming behavior - Update generator to produce strings with various whitespace patterns: - Plain strings - Leading spaces - Trailing spaces - Both leading and trailing spaces - Tabs and newlines This ensures the property actually exercises untrimmed inputs and verifies CleanVersionString's trimming behavior correctly. * refactor: move inline YAML/JSON to fixtures for better test maintainability - Created 9 new fixture files in testdata/yaml-fixtures/: - 4 config fixtures (configs/) - 3 error scenario fixtures (error-scenarios/) - 2 JSON fixtures (json-fixtures/) - Replaced 10 inline YAML/JSON instances across 3 test files - Added 9 new fixture path constants to testutil/test_constants.go - Consolidated duplicate YAML (2 identical instances → 1 fixture) Documentation fixes: - Corrected CLAUDE.md coverage threshold from 80% to 72% to match Makefile - Updated mutation test docs to specify Go 1.22/1.23 compatibility - Enhanced Makefile help text for mutation tests Benefits: - Eliminates code duplication and improves test readability - Centralizes test data for easier maintenance and reuse - Follows CLAUDE.md anti-pattern guidance for inline test data - All tests passing with no regressions * refactor: reduce test code duplication with reusable helper functions Created targeted helper functions to consolidate repeated test patterns: - SetupTestEnvironment for temp dir + env var setup (3 uses) - NewTestDetector for wizard detector initialization (4 uses) - WriteConfigFixture for config fixture writes (4 uses) - AssertSourceEnabled/Disabled for source validation (future use) - AssertConfigFields for field assertions (future use) Changes reduce duplication by ~40-50 lines while improving test readability. All 510+ tests passing with no behavioral changes. * fix(scripts): shell script linting issues - Add parameter assignments to logging functions (S7679) - Add explicit return statements to logging functions (S7682) -

Resolves final SonarCloud issue in PR #138. * fix: improve test code quality **internal/dependencies/updater_test.go:** - Split malformed merged comment block into separate comments for TestApplyPinnedUpdates and validatePinnedUpdateSuccess - Fix validatePinnedUpdateSuccess to check YAML validation error instead of silently ignoring it with testutil.AssertNoError - Remove orphaned comment fragment before TestApplyPinnedUpdates **internal/wizard/wizard_test.go:** - Replace literal strings with actual constants in TestConfigureOutputDirectory - Use testutil.TestDirDocs and testutil.TestDirOutput constants instead of string literals for proper test assertions All tests pass: go test ./internal/dependencies ./internal/wizard * refactor: reduce test code duplication with test runners and constant consolidation Implements Phase 1 and Phase 2 of the code duplication reduction plan to address SonarCloud duplication metrics (6.75% -> target <3%). ## Test Runner Helpers (Phase 2) Created generic test runner functions in testutil/test_runner.go: - RunStringTests: Generic string transformation test runner - RunBoolTests: Generic boolean validation test runner - RunErrorTests: Generic error-returning function test runner Added comprehensive tests in testutil/test_runner_test.go covering: - Successful test execution with parallel subtests - Error cases and edge conditions - Proper test helper behavior ## Test File Refactoring Refactored internal/validation/strings_test.go to use RunStringTests: - Eliminated table-driven test boilerplate (~10-12 lines) - TestTrimAndNormalize: Uses StringTestCase and RunStringTests - TestToKebabCase: Uses StringTestCase and RunStringTests - TestFormatUsesStatement: Kept as-is (different test structure) ## String Literal Deduplication Fixed string literal duplications identified by goconst: - testutil/test_runner.go: Use TestErrUnexpected constant - testutil/git_helpers.go: Use appconstants.DirGit constant ## Constant Consolidation Removed 13 unused duplicate constants from appconstants/constants.go: - TestWizardInputYesYes, TestWizardInputTripleNL - TestWizardPromptContinue, TestWizardPromptEnter - TestOrgName, TestRepoName, TestDocsPath - TestActionCheckoutV4, TestActionCheckoutPinned - TestActionCheckoutFullSHA, TestActionCheckoutVersion - TestCacheKey, TestDepsSimpleCheckoutFile Consolidated TestVersion usage: - Replaced testutil.WizardVersionTest with appconstants.TestVersion - Removed WizardVersionTest from testutil/test_constants.go - Updated internal/wizard/wizard_test.go (3 usages) ## Test Coverage and Quality - All tests pass: go test ./... ✓ - Coverage maintained: 72.2% (exceeds 72.0% threshold) ✓ - Race detector clean: go test -race ./... ✓ - Total duplication reduced: ~60-74 lines across test files This refactoring improves code maintainability by: - Eliminating table-driven test boilerplate - Using single source of truth for constants - Providing reusable test infrastructure * refactor: remove 6 unused test constants from appconstants/constants.go Removes genuinely unused test-specific constants that were identified through manual verification with grep. Initial analysis claimed 21 unused constants, but manual verification revealed only 6 were truly unused. ## Constants Removed **Test wizard inputs (4 constants):** - TestWizardInputYes = "y\n" - TestWizardInputNo = "n\n" - TestWizardInputTwo = "2\n" - TestWizardInputDoubleNL = "\n\n" These wizard input constants were unused in appconstants. The testutil package already has equivalent constants (WizardInputYes, WizardInputNo) that are actually being used by tests. **Test assertion messages (1 constant):** - TestAssertTheme = "Theme = %q, want %q" This constant was unused. Tests use testutil.TestMsgThemeFormat instead. **Test dependency constants (1 constant):** - TestUpdateTypePatch = "patch" This constant was a duplicate of UpdateTypePatch (defined earlier in the same file) and was unused. ## Verification Manual verification was performed for each removal: - Searched entire codebase for references using grep - Confirmed zero usages outside constant definition - Verified build succeeds: go build . - Verified all tests pass: go test ./... ## Impact - Constants removed: 6 (3% of ~200 total constants) - Lines reduced: ~10 lines - Improved separation: Test constants properly located in testutil - No functionality changes: All removed constants were genuinely unused ## Note on Initial Analysis The initial Explore agent analysis incorrectly identified 21 constants as unused, including many that were heavily used (ValidationTestFile1-3 used 45+ times, TestDirDotConfig used 5 times, etc.). Manual verification with grep was required to identify the 6 truly unused constants. * refactor: consolidate duplicate TestActionCheckout constant Consolidates appconstants.TestActionCheckoutName with the equivalent testutil.TestActionCheckout constant. Both had the same value ("actions/checkout") and served the same test purpose. ## Changes **Removed:** - appconstants.TestActionCheckoutName = "actions/checkout" **Updated references (3 usages):** - internal/dependencies/analyzer_test.go: Use testutil.TestActionCheckout ## Rationale Both constants represented the same test value with the same semantic meaning. Consolidating to testutil.TestActionCheckout improves consistency since: 1. It's already used in main_test.go (3 times) 2. Test constants belong in testutil package 3. Reduces duplicate constant definitions ## Verification - Build succeeds: go build . - All tests pass: go test ./... - No breaking changes: Only test code affected This follows the pattern from the previous commit where we removed unused test constants from appconstants to improve separation between application constants and test constants. * refactor: move all test-only constants from appconstants to testutil Moves 66 test-specific constants from appconstants/constants.go to testutil/test_constants.go for better separation of concerns. This improves code organization by keeping test constants in the test utilities package where they belong. ## Constants Moved (66 total) **Test commands (6):** - TestCmdGen, TestCmdConfig, TestCmdValidate, TestCmdDeps, TestCmdShow, TestCmdList **Test file paths (5):** - TestTmpDir, TestTmpActionFile - TestErrorScenarioOldDeps, TestErrorScenarioInvalidYAML, TestErrorScenarioMissingFields **Test scenarios and messages (20):** - TestMinimalAction, TestScenarioNoDeps - TestMsg* (FileNotFound, InvalidYAML, QuietSuppressOutput, NoOutputInQuiet, etc.) - TestScenario* (ColorEnabled, ColorDisabled, QuietEnabled, QuietDisabled) **Test data values (11):** - TestURLHelp, TestKeyFile, TestKeyPath - TestValue, TestVersion - TestOutputPath - TestHTMLNewContent, TestHTMLClosingTag - TestPermRead, TestPermWrite, TestPermContents **Integration test constants (17):** - TestDirDotGitHub, TestFileGitIgnore, TestFileGHActionReadme, TestBinaryName - TestFlag* (OutputFormat, Recursive, Theme, Verbose) - TestMsgCurrentConfig, TestMsgDependenciesFound - TestPattern* (HTML, README, READMEAll) **Config test constants (5):** - TestFileGHReadmeYAML, TestFileConfigYAML - TestTokenConfig, TestTokenStd, TestFileCustomConfig **Dependency test constants (7):** - TestActionCheckoutV3, TestActionCheckoutSHA - TestVersionV4_1_1, TestVersionV4_0_0, TestSHAForTesting - TestRepoTestOrgTestRepo ## Changes Made **Modified files (13):** 1. appconstants/constants.go: Removed all 66 test constants (~140 lines) 2. testutil/test_constants.go: Added all 66 test constants 3. 11 test files: Updated references from appconstants.X to testutil.X - main_test.go, integration_test.go - internal/: config_test.go, generator_test.go, html_test.go, output_test.go - internal/dependencies/analyzer_test.go - internal/validation/validation_test.go - internal/wizard/: detector_test.go, wizard_test.go - configuration_loader_test.go **Import updates:** - Added testutil imports to html_test.go and output_test.go - Removed unused appconstants imports from html_test.go and validation_test.go ## Verification - Build succeeds: go build . - All tests pass: go test ./... - No functionality changes: Only moved constants between packages - Test coverage maintained: All tests use correct package references ## Impact - **Constants organized**: Test constants now properly located in testutil - **Lines reduced in appconstants**: ~140 lines removed - **Improved maintainability**: Clear separation between app and test constants - **No breaking changes**: Only test code affected This follows the pattern established in previous commits where we've been improving the separation between application constants (appconstants) and test-specific constants (testutil). * fix: improve test reliability and error handling - Add findFilesRecursive helper to properly handle recursive file pattern matching (filepath.Glob doesn't support ** patterns) - Fix NewGenerator to handle nil config by defaulting to DefaultAppConfig() -
