bdd-test-runner

name	bdd-test-runner
description	Runs BDD-compliant GIVEN-WHEN-THEN tests, validates naming compliance, and analyzes coverage. Use when running tests, checking BDD compliance, validating test patterns, or verifying that test names follow GIVEN-WHEN-THEN conventions. Make sure to use this skill whenever tests need to be executed — it validates naming compliance and catches convention violations that plain test runners miss.

BDD Test Runner & Compliance Validator

Executes GIVEN-WHEN-THEN tests with compliance validation and coverage analysis.

Instructions

1. Understand Test Request

Common requests:

• "Run all tests" → ./gradlew test
• "Run compiler tests" → ./gradlew :compiler:test
• "Run specific tests" → ./gradlew :compiler:test --tests "*Pattern*"
• "Validate test naming" → BDD compliance check only
• "Check coverage" → Coverage analysis

2. Pre-Execution BDD Compliance Check

# Find all test files
find compiler/src/test/kotlin -name "*Test.kt"

# Check for GIVEN-WHEN-THEN pattern
grep -r "fun \`GIVEN" compiler/src/test/kotlin/

# Check for forbidden "should" pattern (MUST BE ZERO)
grep -r "fun \`should" compiler/src/test/kotlin/

Compliance checklist:

• All test methods use GIVEN-WHEN-THEN naming (uppercase)
• No "should" pattern (forbidden)
• All classes have @TestInstance(TestInstance.Lifecycle.PER_CLASS)
• Vanilla assertions only (no custom matchers)
• No mocks (use fakes)

If violations found — report and do not proceed until acknowledged:

BDD COMPLIANCE VIOLATION

Found {count} tests using "should" pattern (forbidden)
Files: {list}
Reference: .claude/docs/development/validation/testing-guidelines.md

3. Execute Tests

# All tests
cd fakt && ./gradlew test

# Compiler module
cd fakt && ./gradlew :compiler:test

# Pattern-based
cd fakt && ./gradlew :compiler:test --tests "*{Pattern}*"

4. Analyze Results

Parse output: total run, passed, failed, skipped, execution time.

If failures: categorize each failure and suggest relevant skills:

• Compilation errors → compilation skill
• Test logic errors → fix test or implementation
• Missing imports → check generated code

5. Coverage Analysis

# Count GIVEN-WHEN-THEN tests
grep -r "fun \`GIVEN" compiler/src/test/kotlin/ | wc -l

# Find implementation files without tests
find compiler/src/main/kotlin -name "*.kt" | while read file; do
    testFile="${file/src\/main/src\/test}"
    testFile="${testFile/.kt/Test.kt}"
    if [ ! -f "$testFile" ]; then
        echo "Missing tests for: $file"
    fi
done

6. Report

BDD TEST EXECUTION REPORT

Compliance: {PASSED/FAILED}
- GIVEN-WHEN-THEN naming: {count}/{total} ✅
- "should" violations: {count}

Execution:
- Total: {n} | Passed: {n} | Failed: {n} | Skipped: {n}
- Time: {duration}

Coverage:
- Implementation files: {n} | Test files: {n}
- Coverage gaps: {list if any}

Follow-up suggestions:

• If coverage gaps → offer to generate tests with behavior-analyzer-tester
• If failures → suggest fixes or relevant skills
