## [1.0.10] - 2025-11-16
### Fixed
#### CI/CD Infrastructure
- **setrlimit Test Isolation**: Ignored 5 setrlimit-related tests in Linux CI environments to prevent memory exhaustion during parallel test execution
- Tests were setting process-wide memory limits (100MB) that affected other parallel tests
- Prevented "failed to allocate an alternative stack" errors in Code Coverage and test runs
- Tests still run in local development and macOS/Windows environments
- **Multi-Shell Test Support**: Added zsh installation to Ubuntu CI environments
- Enabled all 3 multi-shell tests (bash/zsh/sh) to pass in Test and Publish Reports workflow
- Fixed 2/3 test pass rate to 3/3 by installing missing zsh package
#### Windows Platform
- **Job Object Support**: Added `Win32_System_Threading` feature to enable Windows Job Objects for resource limiting
#### Documentation
- **API Documentation**: Fixed rustdoc examples to match current API signatures
- **HTML Tag Escaping**: Properly escaped HTML tags in rustdoc comments
### Changed
- **Author Contact**: Updated author email to real address for better communication
## [1.0.0] - 2025-11-11
### Added - Complete Rust v1.0 Implementation
#### Phase 1: Core Types & Architecture
- Comprehensive type system for CLI analysis (`CliAnalysis`, `CliOption`, `Subcommand`)
- Test case types with 9 categories (Basic, Help, Security, Path, Multi-Shell, Input Validation, Destructive Ops, Performance, Directory Traversal)
- Test report types (`TestReport`, `TestSuite`, `TestResult`, `TestStatus`)
- Error handling with `thiserror` and enhanced user messages using `colored`
#### Phase 2: Analyzer Module
- `CliParser` for binary execution and help output parsing
- Regex-based option extraction (short/long options, descriptions, types)
- `SubcommandDetector` for recursive subcommand discovery
- Version string extraction with multiple fallback strategies
- Resource limits for DOS protection (500MB memory, 1024 FDs, 300s timeout)
- Utility functions: `execute_with_timeout`, `validate_binary_path`
#### Phase 3: Generator Module
- `TestGenerator` for test case generation across 9 categories
- Parallel test generation with `rayon` (15-132x faster than Bash prototype)

- Validation of generated BATS syntax
#### Phase 4: Runner & Reporter Modules
- `BatsExecutor` for BATS test execution with TAP parsing
- Environment information gathering (OS, shell, hostname, timestamp)
- Four report formats:
- **Markdown**: Human-readable summary with statistics
- **JSON**: Machine-readable format for CI/CD integration
- **HTML**: Interactive report with embedded Bootstrap 5 (no CDN)
- **JUnit XML**: Standard format for CI/CD systems
#### Phase 5: Polish & Optimization

### CLI Commands
```bash
# Analyze a CLI binary
cli-testing-specialist analyze /usr/bin/curl -o curl-analysis.json
# Generate test cases (9 categories available)
cli-testing-specialist generate curl-analysis.json -o tests/ -c all
# Or specific categories: basic,security,performance
# Run tests and generate reports
cli-testing-specialist run tests/ -f all -o reports/
# Format options: markdown, json, html, junit, all
# Run with custom timeout and skip categories (v1.0.0+)
cli-testing-specialist run tests/ \
-f html \
-o reports/ \
--timeout 60 \
--skip destructive-ops,directory-traversal
# Generate shell completion
cli-testing-specialist completion bash > cli-testing-specialist.bash
# Shells: bash, zsh, fish, powershell, elvish
# Validate BATS files (planned for Phase 2)
cli-testing-specialist validate tests/
```
### Test Categories
1. **Basic**: Help, version, exit codes
2. **Help**: Subcommand help messages
3. **Security**: Command injection, path traversal, XSS
4. **Path**: Special characters, Unicode, deep hierarchies
5. **Multi-Shell**: bash/zsh compatibility
6. **Input Validation**: Numeric, path, enum options
7. **Destructive Ops**: Confirmation prompts, --yes/--force flags
8. **Performance**: Large file handling, timeouts
9. **Directory Traversal**: Deep hierarchies, symlink loops, large directories
### Performance Targets (All Exceeded)
- **Speed**: 10x faster than Bash → Achieved 15-132x
- **Memory**: <50MB → Achieved 6-68MB
- **Accuracy**: 95% option detection → Achieved ~100% for standard help formats
- **Coverage**: 9 test categories → Achieved all 9
### Security Features
- DOS protection with resource limits
- Input validation for binary paths
- Secure temporary directory handling (umask 077)
- License compliance checking (cargo deny)
- Dependency vulnerability scanning (cargo audit)
### Technical Stack
- **Language**: Rust 2021 edition
- **CLI**: clap v4.5 with derive API
- **Async**: tokio with full features
- **Parallel**: rayon for multi-threaded processing
- **Serialization**: serde, serde_json, serde_yaml
- **Testing**: BATS (Bash Automated Testing System)
- **Reports**: Markdown, JSON, HTML (Bootstrap 5), JUnit XML
- **Benchmarks**: Criterion for performance measurement
### Known Limitations
- Git and other non-standard help formats may not detect subcommands correctly
(workaround: manual subcommand specification planned for v1.1)
- BATS files cannot be validated with `bash -n` (use `bats` command instead)
### Migration from Bash Prototype
This release replaces the Bash v1.0 prototype entirely. No migration path is provided
as the Rust implementation offers:
- 15-132x performance improvement
- Type-safe implementation
- Comprehensive test coverage
- Professional-grade error handling
- Four report formats (vs. one in Bash)
- Parallel processing support
## [1.0.5] - 2025-11-12
### Changed
- **Dependency Updates**: All dependencies updated to latest versions via Dependabot
- GitHub Actions: upload-artifact v3→v4, download-artifact v3→v4, configure-pages 4→5
- indicatif: 0.17→0.18 (progress indicator improvements)
- thiserror: 1.0→2.0 (error handling enhancements)
- colored: 2.1→3.0 (terminal color output updates)
- criterion: 0.5→0.7 (benchmarking framework update, MSRV 1.80)
### Fixed
- **Breaking Change Migration**: criterion 0.5→0.7
- Migrated `criterion::black_box` to `std::hint::black_box` (benches/benchmark.rs)
- Updated to criterion 0.6+ API changes (removed deprecated `real_blackbox` feature)
- MSRV bumped to Rust 1.80 (required by criterion 0.6+)
### Added
- **Development Workflow**: `.claude/CLAUDE.md` Git Hooks configuration
- pre_commit: `cargo fmt` (1-2 seconds, automatic formatting)
- pre_push: `cargo clippy --all-features -- -D warnings` + `cargo test --all-features --lib --bins` (10-30 seconds)
### Security
- All dependencies audited with `cargo audit`: 0 vulnerabilities
- All 7 Dependabot PRs merged after verification (100% success rate)
## [1.0.9] - 2025-11-12
### Added
- **Execution-based Inference**: Revolutionary no-args behavior detection
- Directly executes binaries without arguments to measure actual exit codes
- 100% inference accuracy (vs. 66.7% with Usage line parsing in v1.0.8)
- Solves cldev-type CLI problem (identical Usage patterns, different behaviors)
- Safety measures: 1-second timeout, output discarding, non-TTY mode
- Dependency: `wait-timeout = "0.2"` for process timeout handling
### Changed
- **Inference Algorithm Priority**:
1. **Strategy 0**: Interactive tools detection (BEFORE execution to avoid false positives)
2. **Strategy 1**: Execution-based inference (most accurate)
3. **Strategy 2**: Usage line parsing (fallback)
4. **Strategy 3**: Subcommands presence check (fallback)
5. **Default**: ShowHelp (safest assumption)
### Fixed
- **HTML Report Filter Bug**: Skipped filter now correctly hides error detail rows
- JavaScript `filterTests()` now handles error rows (`<tr class="bg-light">`)
- Error rows follow parent test row visibility state
- No more "Error: Test X failed" appearing in Skipped filter
### Performance
- **Analysis Time Impact**: +0.8% (22ms for cldev, within 1-second timeout)
- **Test Success Rate**: 93.3% → 100% (15/15 tests passed)
- **Inference Accuracy**: 66.7% → 100% (cldev/cmdrun/backup-suite all correct)
### Technical Details
- New method: `BehaviorInferrer::execute_and_measure()`
- Exit code mapping: 0 → ShowHelp, 1|2 → RequireSubcommand
- Interactive tools (python3, psql) checked before execution (avoid stdin=null edge case)
- 109 unit tests passing (100% pass rate)
## [1.0.8] - 2025-11-12
### Fixed
- **No-Args Test Assertion Relaxation**: Removed strict output assertions
- `RequireSubcommand` pattern: Removed `run.output` check (diverse error formats)
- `ShowHelp` pattern: Removed `run.output` check (some CLIs output nothing)
- Exit code validation remains (Unix standard: 0 = success, non-zero = error)
### Changed
- **Test Generation Philosophy**: Rely on exit codes, not output format
- Reason: CLIs show different error formats (short message vs full help)
- Example: backup-suite exits 0 with no output (valid ShowHelp behavior)
### Performance
- **Test Success Rate**: 86.7% → 93.3% (cmdrun 4/5→5/5, backup-suite 4/5→5/5)
- **Remaining Issue**: cldev basic-005 still fails (Usage line ambiguity, fixed in v1.0.9)
## [1.0.7] - 2025-11-12
### Fixed
- **Clippy Warning**: Renamed `TestCategory::default()` to `standard_categories()`
- Reason: Method name conflicts with Rust's `Default::default()` trait
- Affected files: `src/types/test_case.rs`, `src/main.rs`
### Changed
- **Git Hooks**: Added pre_commit and pre_push hooks in `.claude/CLAUDE.md`
- `pre_commit`: `cargo fmt` (automatic formatting)
- `pre_push`: `cargo clippy + cargo test` (quality gate)
## [1.0.6] - 2025-11-12
### Added
- **Required Arguments Detection**: Automatic extraction from Usage lines
- New field: `Subcommand.required_args` (e.g., `<ID>`, `<FILE>`)
- Parser: `CliParser::parse_required_args()` method
- Integration: `SubcommandDetector` populates required_args during analysis
### Changed
- **Test Template Improvements**:
- Destructive operations tests now generate dummy arguments (e.g., `--dummy-id-12345`)
- Security tests use dynamic option selection (actual options from analysis)
- Exit code expectation: 1 → 2 (clap standard for invalid arguments)
### Performance
- **Test Success Rate**: 85.0% → 92.9% for cmdrun (17/20 → 26/28 tests)
- **Failures Reduced**: 5 → 2 (fixed 3 issues: required args, exit code, non-existent options)
### Technical Details
- Files modified: `src/types/analysis.rs`, `src/analyzer/cli_parser.rs`,
`src/analyzer/subcommand_detector.rs`, `src/generator/test_generator.rs`
