# Testing

> Learn how to test your contributions to Nile Auth

## Overview

### Types of Tests

* Unit Tests
* Integration Tests
* End-to-End Tests
* Performance Tests

## Unit Testing

### Writing Unit Tests

```typescript theme={null}
// Example unit test
import { describe, it, expect } from 'vitest';
import { validateEmail } from '../utils/validation';

describe('validateEmail', () => {
  it('should validate correct email format', () => {
    expect(validateEmail('test@example.com')).toBe(true);
  });
});
```

### Test Coverage

* Aim for 80% or higher coverage
* Focus on critical paths
* Test edge cases

## Integration Testing

### Setting Up Integration Tests

```typescript theme={null}
// Example integration test
import { describe, it, expect } from 'vitest';
import { AuthClient } from '../client';

describe('AuthClient', () => {
  it('should authenticate user', async () => {
    // Placeholder test implementation
  });
});
```

### Test Environment

1. Configure test database
2. Mock external services
3. Set up test fixtures

## End-to-End Testing

### E2E Test Setup

```typescript theme={null}
// Example E2E test
import { test, expect } from '@playwright/test';

test('user can sign in', async ({ page }) => {
  // Placeholder E2E test
});
```

### Running E2E Tests

1. Start test environment
2. Execute test suite
3. Generate reports

## Performance Testing

### Load Testing

```typescript theme={null}
// Example load test
import { check } from 'k6';
import http from 'k6/http';

export default function () {
  // Placeholder load test
}
```

### Benchmarking

* Response times
* Concurrent users
* Resource usage

## Test Best Practices

### Writing Tests

* Keep tests focused and simple
* Use descriptive test names
* Follow AAA pattern (Arrange, Act, Assert)
* Mock external dependencies

### Test Organization

```
tests/
├── unit/
├── integration/
├── e2e/
└── performance/
```

## Continuous Integration

### CI Pipeline

1. Run linting
2. Execute unit tests
3. Run integration tests
4. Perform E2E tests
5. Check coverage

### Test Automation

```yaml theme={null}
# Example GitHub Actions workflow
name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      # Placeholder CI steps
```

## Debugging Tests

### Common Issues

* Async timing problems
* Test isolation
* Environment setup
* Flaky tests

### Tools and Techniques

* Test debugger
* Logging
* Snapshot testing
* Test runners

## Best Practices

* Write tests before code (TDD)
* Keep tests maintainable
* Use test fixtures
* Document test requirements
