Test Suite Setup

Test Suite Setup Skill

Help set up test validation for any project to enable closed-loop workflows.

When to Use

• Setting up validation commands for a new project
• Discovering existing test infrastructure
• Creating a validation stack for CI/CD or agentic workflows
• Standardizing test commands across a codebase

Setup Workflow

Step 1: Detect Project Type

Look for configuration files to identify the stack:

Step 2: Identify Existing Test Infrastructure

Check for test directories and configurations:

# Common test locations
ls -la tests/ test/ __tests__/ spec/

# Check for test config files
ls -la pytest.ini jest.config.* vitest.config.* .mocharc.*

Step 3: Extract Available Commands

For Node.js projects:

# Show available npm scripts
cat package.json | grep -A 30 '"scripts"'

For Python projects:

# Check pyproject.toml for tools
cat pyproject.toml | grep -A 10 '\[tool\.'

Step 4: Generate Validation Commands

Create a validation stack appropriate for the project:

Template:

## Validation Commands

Execute every command to validate with 100% confidence

- `[lint command]` - Code style and syntax
- `[type check command]` - Type safety (if applicable)
- `[test command]` - Behavior correctness
- `[build command]` - Production readiness

Quick Reference by Stack

Python (uv + pytest)

## Validation Commands

- `uv run ruff check .` - Linting
- `uv run mypy .` - Type checking
- `uv run pytest -v` - Tests

Python (pip + pytest)

## Validation Commands

- `flake8 .` or `ruff check .` - Linting
- `mypy .` - Type checking
- `pytest -v` - Tests

TypeScript/JavaScript (npm)

## Validation Commands

- `npm run lint` - ESLint
- `npx tsc --noEmit` - Type checking
- `npm test` - Tests
- `npm run build` - Build verification

TypeScript (Bun)

## Validation Commands

- `bun run lint` - Linting
- `bun tsc --noEmit` - Type checking
- `bun test` - Tests
- `bun run build` - Build verification

Go

## Validation Commands

- `go fmt ./...` - Formatting
- `go vet ./...` - Static analysis
- `go test ./... -v` - Tests
- `go build ./...` - Build verification

Rust

## Validation Commands

- `cargo fmt --check` - Formatting
- `cargo clippy` - Linting
- `cargo test` - Tests
- `cargo build --release` - Build verification

Fallback: No Test Infrastructure

If no test infrastructure exists, recommend setup:

Python

# Install pytest
uv add --dev pytest pytest-cov

# Create test directory
mkdir tests
touch tests/__init__.py
touch tests/test_example.py

TypeScript

# Install vitest (modern, fast)
npm install -D vitest

# Or Jest
npm install -D jest @types/jest ts-jest

# Create test directory
mkdir __tests__

Verification

After setup, verify the validation stack works:

# Run each command and confirm success
[lint command]    # Should exit 0
[type command]    # Should exit 0
[test command]    # Should exit 0
[build command]   # Should exit 0
