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):
bun test --dots --bail=1 $PATTERN
With coverage:
bun test --dots --coverage $PATTERN
Filter by test name (not file path):
bun test --dots --bail=1 -t "pattern"
Watch mode:
bun test --watch $PATTERN
CI mode (JUnit output):
bun test --reporter=junit --reporter-outfile=junit.xml $PATTERN
Output Interpretation
| Symbol | Meaning |
|---|
. | Test passed |
F | Test failed |
S | Test skipped |
Post-test
- Report pass/fail summary
- If failures: show first failure details
- If coverage enabled: report coverage percentage
