Test Structure + +Each test file follows a consistent structure: + +```typescript +/// + +import { describe, test, expect, beforeAll, afterAll } from '@jest/globals'; +import { createRunner, AwfRunner } from '../fixtures/awf-runner'; +import { cleanup } from '../fixtures/cleanup'; + +describe('Feature Name', () => { + let runner: AwfRunner; + + beforeAll(async () => { + await cleanup(false); // Clean up before tests + runner = createRunner(); + }); + + afterAll(async () => { + await cleanup(false); // Clean up after tests + }); + + test('should do something', async () => { + const result = await runner.runWithSudo('command', { + allowDomains: ['github.com'], + logLevel: 'debug', + timeout: 60000, + }); + + expect(result).toSucceed(); + }, 120000); // Set individual test timeout +}); +``` + +### 2. Use Custom Matchers + +```typescript +// Check success/failure +expect(result).toSucceed(); +expect(result).toFail(); + +// Check specific exit code +expect(result).toExitWithCode(0); +expect(result).toExitWithCode(42); + +// Check timeout +expect(result).toTimeout(); +``` + +### 3. Handle Timeouts + +- Set reasonable timeouts for each test (typically 120000ms for integration tests) +- Use `--max-time` with curl to prevent indefinite hangs +- Set `timeout` in runner options + +### 4. Clean Up Resources + +- Always run `cleanup(false)` in `beforeAll` and `afterAll` +- Use `keepContainers: true` only when needed for log inspection +- Clean up manually created files in `afterEach` + +### 5. Avoid Flaky Tests + +- Use explicit timeouts with network commands +- Don't depend on timing-sensitive conditions +- Use `|| true` or error handling for expected failures +- Test for specific exit codes, not just success/failure + +### 6. Group Related Tests + +```typescript +describe('Feature Category', () => { + describe('Subsection A', () => { + test('scenario 1', ...); + test('scenario 2', ...); + }); + + describe('Subsection B', () => { + test('scenario 3', ...);
