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:
| File | Project Type |
|---|---|
package.json |
Node.js / TypeScript |
pyproject.toml |
Python (modern) |
requirements.txt |
Python (pip) |
go.mod |
Go |
Cargo.toml |
Rust |
pom.xml |
Java (Maven) |
build.gradle |
Java (Gradle) |
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
