# /bun:test Run tests using Bun's built-in test runner with optimized output. ## When to Use This Skill | Scenario | Use this skill | Alternative | |----------|---------------|-------------| | Quickly running tests with compact output | Yes | N/A | | Running a specific test file or pattern | Yes | N/A | | Running tests with coverage | Yes | N/A | | Configuring test runner options in detail | No - use `bun-development` | Full test configuration guidance | | Debugging failing tests interactively | No - use `typescript-debugging` | Inspector-based debugging | ## Parameters - `pattern` (optional): Test file or name pattern - `--coverage`: Enable code coverage reporting - `--bail`: Stop on first failure - `--watch`: Watch mode for development ## Execution **Quick feedback (default for agentic use):** ```bash bun test --dots --bail=1 $PATTERN ``` **With coverage:** ```bash bun test --dots --coverage $PATTERN ``` **Filter by test name (not file path):** ```bash bun test --dots --bail=1 -t "pattern" ``` **Watch mode:** ```bash bun test --watch $PATTERN ``` **CI mode (JUnit output):** ```bash bun test --reporter=junit --reporter-outfile=junit.xml $PATTERN ``` ## Output Interpretation | Symbol | Meaning | |--------|---------| | `.` | Test passed | | `F` | Test failed | | `S` | Test skipped | ## Post-test 1. Report pass/fail summary 2. If failures: show first failure details 3. If coverage enabled: report coverage percentage
