Test Runner Skill

Universal test execution patterns for various testing frameworks.

Auto-Detect Test Framework

# Detect which test framework is being used
if [ -f "package.json" ]; then
  if grep -q "\"jest\"" package.json; then
    TEST_FRAMEWORK="jest"
  elif grep -q "\"vitest\"" package.json; then

  elif grep -q "\"mocha\"" package.json; then

elif [ -f "pytest.ini" ] || [ -f "pyproject.toml" ]; then

Usage

# From commands, set TEST_SCOPE then source appropriate sections:
TEST_SCOPE="unit"  # or "integration", "e2e", "all"

# Auto-detect framework
# ... (include Auto-Detect section)

# Run tests
if [ "$TEST_SCOPE" = "all" ]; then
  # ... (include Run All Tests section)
else
  # ... (include Run Specific Test Suite section)
fi

# Run quality checks
