 # Stock Bot Coverage CLI
 A custom coverage tool for the Stock Bot monorepo that provides advanced coverage reporting with support for excluding directories (like `dist/`) and beautiful reporting options.
 ## Features
 - 🚫 **Exclusion Support**: Exclude directories like `dist/`, `node_modules/`, and test files from coverage
 - 📊 **Multiple Reporters**: Terminal, HTML, JSON, and Markdown reports
 - 🎯 **Threshold Enforcement**: Set and enforce coverage thresholds
 - 📦 **Monorepo Support**: Works seamlessly with workspace packages
 - 🎨 **Beautiful Reports**: Interactive HTML reports and colored terminal output
 - 🔧 **Configurable**: Use `.coveragerc.json` or CLI flags
 ## Installation
 The tool is already part of the Stock Bot monorepo. Just run:
 ```bash
 bun install
 ```
 ## Usage
 ### Basic Usage
 Run coverage for all packages:
 ```bash
 bun run coverage
 ```
 ### Generate HTML Report
 ```bash
 bun run coverage:html
 ```
 ### CI Mode
 Generate markdown and JSON reports, fail if below threshold:
 ```bash
 bun run coverage:ci
 ```
 ### Run for Specific Packages
 ```bash
 bun run coverage --packages core utils
 ```
 ### Custom Exclusions
 ```bash
 bun run coverage --exclude "**/dist/**" "**/generated/**" "**/vendor/**"
 ```
 ### Set Thresholds
 ```bash
 bun run coverage --threshold 85 --threshold-functions 80
 ```
 ## Configuration
 Create a `.coveragerc.json` file in your project root:
 ```json
 {
  "exclude": [
    "**/node_modules/**",
    "**/dist/**",
    "**/build/**",
    "**/coverage/**",
    "**/*.test.ts",
    "**/*.test.js",
    "**/test/**",
    "**/tests/**"
  ],
  "reporters": ["terminal", "html"],
  "thresholds": {
    "lines": 80,
    "functions": 80,
    "branches": 80,
    "statements": 80
  },
  "outputDir": "coverage"
 }
 ```
 Or create one with:
 ```bash
 bun run coverage init
 ```
 ## Reporters
 ### Terminal Reporter
 Beautiful colored output in your terminal:
 ```
 ═══════════════════════════════════════════════════════════
          Stock Bot Coverage Report
 ═══════════════════════════════════════════════════════════

 └────────────────┴──────────┴──────────┴──────────┴────────────┘
 ✓ 15 packages meet coverage thresholds
 ⚠ 2 packages below threshold
 ```
 ### HTML Reporter
 Interactive HTML report with:
 - Package breakdown
 - File-level coverage
 - Beautiful charts and visualizations
 - Responsive design
 ### Markdown Reporter
 Perfect for CI/CD comments on pull requests:
 - Summary tables
 - Package details
 - Threshold status
 - File breakdowns
 ### JSON Reporter
 Machine-readable format for:
 - Custom tooling integration
 - Historical tracking
 - CI/CD pipelines
 ## CLI Options
 | Option | Description |
 |--------|-------------|
 | `-p, --packages <packages...>` | Run coverage for specific packages |
 | `-e, --exclude <patterns...>` | Glob patterns to exclude from coverage |
 | `-i, --include <patterns...>` | Glob patterns to include in coverage |
 | `-r, --reporters <reporters...>` | Coverage reporters to use |
 | `-t, --threshold <number>` | Set coverage threshold for all metrics |
 | `--threshold-lines <number>` | Set line coverage threshold |
 | `--threshold-functions <number>` | Set function coverage threshold |
 | `--threshold-branches <number>` | Set branch coverage threshold |
 | `--threshold-statements <number>` | Set statement coverage threshold |
 | `-o, --output-dir <path>` | Output directory for reports |
 | `-c, --config <path>` | Path to coverage config file |
 | `--fail-under` | Exit with non-zero code if below threshold |
 ## How It Works
 1. **Test Execution**: Runs `bun test` for each package
 2. **Data Collection**: Currently simulates coverage data based on test results (Bun's coverage feature is not yet fully implemented)
 3. **Filtering**: Applies exclusion patterns to remove unwanted files
 4. **Processing**: Merges coverage data across packages
 5. **Reporting**: Generates reports in requested formats
 > **Note**: This tool currently generates simulated coverage data based on test results because Bun's `--coverage` flag doesn't yet produce LCOV output. Once Bun's coverage feature is fully implemented, the tool will be updated to use actual coverage data.
 ## Why This Tool?
 Bun's built-in coverage tool lacks several features needed for large monorepos:
 - No way to exclude directories like `dist/`
 - Limited reporting options
 - No per-package thresholds
 - Basic terminal output
 This tool addresses these limitations while maintaining compatibility with Bun's test runner.
 ## Contributing
 The coverage tool is located in `tools/coverage-cli/`. To work on it:
 1. Make changes in `tools/coverage-cli/src/`
 2. Test with `bun run coverage`
 3. Build with `bun build tools/coverage-cli/src/index.ts`
