ln-782-test-runner

Type: L3 Worker Category: 7XX Project Bootstrap Parent: ln-780-bootstrap-verifier

Purpose

Detects test frameworks, executes all test suites, and reports results including pass/fail counts and optional coverage.

Scope:

  • Auto-detect test frameworks from project configuration
  • Execute test suites for all detected frameworks
  • Parse test output for pass/fail counts
  • Generate coverage reports when enabled

Out of Scope:

  • Building projects (handled by ln-781)
  • Container operations (handled by ln-783)
  • Writing or fixing tests

When to Use

| Scenario | Use This Skill | |----------|---------------| | Called by ln-780 orchestrator | Yes | | Standalone test execution | Yes | | CI/CD pipeline test step | Yes | | Build verification needed | No, use ln-781 |

Workflow

Step 1: Detect Test Frameworks

Identify test frameworks from project configuration files.

| Marker | Test Framework | Project Type | |--------|---------------|--------------| | vitest.config.* | Vitest | Node.js | | jest.config.* | Jest | Node.js | | *.test.ts in package.json | Vitest/Jest | Node.js | | xunit / nunit in *.csproj | xUnit/NUnit | .NET | | pytest.ini / conftest.py | pytest | Python | | *_test.go files | go test | Go | | tests/ with Cargo.toml | cargo test | Rust |

Step 2: Execute Test Suites

Run tests for each detected framework.

| Framework | Execution Strategy | |-----------|-------------------| | Vitest | Run in single-run mode with JSON reporter | | Jest | Run with JSON output | | xUnit/NUnit | Run with logger for structured output | | pytest | Run with JSON plugin or verbose output | | go test | Run with JSON output flag | | cargo test | Run with standard output parsing |

Step 3: Parse Results

Extract test results from framework output.

| Metric | Description | |--------|-------------| | total | Total number of tests discovered | | passed | Tests that completed successfully | | failed | Tests that failed assertions | | skipped | Tests marked as skip/ignore | | duration | Total execution time |

Step 4: Generate Coverage (Optional)

When coverage enabled, collect coverage metrics.

| Framework | Coverage Tool | |-----------|--------------| | Vitest/Jest | c8 / istanbul | | .NET | coverlet | | pytest | pytest-cov | | Go | go test -cover | | Rust | cargo-tarpaulin |

Coverage Metrics: | Metric | Description | |--------|-------------| | linesCovered | Lines executed during tests | | linesTotal | Total lines in codebase | | percentage | Coverage percentage |

Step 5: Report Results

Return structured results to orchestrator.

Result Structure:

| Field | Description | |-------|-------------| | suiteName | Test suite identifier | | framework | Detected test framework | | status | passed / failed / error | | total | Total test count | | passed | Passed test count | | failed | Failed test count | | skipped | Skipped test count | | duration | Execution time in seconds | | failures | Array of failure details (test name, message) | | coverage | Coverage metrics (if enabled) |

Error Handling

| Error Type | Action | |------------|--------| | No tests found | Report warning, status = passed (0 tests) | | Test timeout | Report timeout, include partial results | | Framework error | Log error, report as error status | | Missing dependencies | Report missing test dependencies |

Options

| Option | Default | Description | |--------|---------|-------------| | skipTests | false | Skip execution if no tests found | | allowFailures | false | Report success even if tests fail | | coverage | false | Generate coverage report | | timeout | 300 | Max execution time in seconds | | parallel | true | Run test suites in parallel when possible |

Critical Rules

  1. Run all detected test suites - do not skip suites silently
  2. Parse actual results - do not rely only on exit code
  3. Include failure details - provide actionable information for debugging
  4. Respect timeout - prevent hanging on infinite loops

Definition of Done

  • [ ] All test frameworks detected
  • [ ] All test suites executed
  • [ ] Results parsed and structured
  • [ ] Coverage collected (if enabled)
  • [ ] Results returned to orchestrator
