{project} Testing Patterns
Custom testing patterns, fixtures, and strategies for this project.
Variables
| Variable | Default | Description |
|---|---|---|
| COVERAGE_TARGET | 80 | Minimum coverage percentage |
| E2E_TIMEOUT | 30000 | E2E test timeout in ms |
| PARALLEL_TESTS | true | Run tests in parallel when possible |
Instructions
- Identify test type needed (unit/integration/e2e)
- Use appropriate fixtures and patterns
- Follow project naming conventions
- Ensure proper cleanup
Red Flags - STOP and Reconsider
If you're about to:
- Write a test without proper isolation
- Skip cleanup in fixtures
- Hardcode test data instead of using fixtures
- Write flaky tests (timing-dependent, order-dependent)
STOP -> Use proper fixtures -> Ensure isolation -> Then write test
Test Categories
Unit Tests
Location: tests/unit/
Patterns:
- Test single functions/methods in isolation
- Mock external dependencies
- Fast execution (< 100ms each)
Integration Tests
Location: tests/integration/
Patterns:
- Test component interactions
- Use test database/fixtures
- May have external dependencies
E2E Tests
Location: tests/e2e/ or playwright/
Patterns:
- Test full user workflows
- Use browser automation
- Longer execution time acceptable
Fixtures
Database Fixtures
Location: tests/fixtures/
Usage:
# Python example
from tests.fixtures import sample_user, sample_order
def test_order_creation(sample_user, sample_order):
# Test uses pre-configured fixtures
pass
Mock Services
Location: tests/mocks/
Available mocks:
- [TODO: List project-specific mocks]
Naming Conventions
| Test Type | File Pattern | Function Pattern |
|---|---|---|
| Unit | test_*.py |
test_<function>_<scenario> |
| Integration | test_*_integration.py |
test_<component>_<action> |
| E2E | *.spec.ts |
test('<feature> - <scenario>') |
Coverage Requirements
| Component | Minimum Coverage |
|---|---|
| Core logic | 90% |
| API routes | 80% |
| Utilities | 70% |
CI Integration
Tests run in CI:
- On PR: unit + integration
- On merge: all including E2E
- Nightly: full regression suite
Customization
Edit this file to add:
- New fixture definitions
- Additional mock services
- Custom test patterns
- Coverage exceptions
