Testing patterns and standards for this codebase, including async effects, fakes vs mocks, and property-based testing.
Write and evaluate effective Python tests using pytest. Use when writing tests, reviewing test code, debugging test failures, or improving test coverage. Covers test design, fixtures, parameterization, mocking, and async testing.
Load PROACTIVELY when task involves writing tests, improving coverage, or test infrastructure. Use when user says "add tests", "write unit tests", "set up E2E testing", "improve coverage", or "add mocks". Covers Vitest/Jest unit tests, React Testing Library component tests, Playwright E2E tests, MSW API mocking, test organization and naming, fixture management, coverage targets and thresholds, snapshot testing, and CI integration.
Vitest testing framework for unit, component, and integration tests. Covers test structure (describe/it/test.each), assertions with expect, lifecycle hooks, mocking (vi.fn/vi.mock/vi.spyOn), React Testing Library patterns, hook testing with renderHook, user-event interactions, async utilities, configuration, workspace setup, coverage, and advanced patterns like in-source testing and concurrent execution. Use when writing unit tests, component tests, integration tests, or testing React hooks. Use for test configuration, mocking modules, testing async behavior, snapshot testing, or setting up test coverage.
Use when writing or reviewing Java unit tests. Enforces Mockito/JUnit 5 best practices - strict stubbing, no lenient mode, specific matchers, complete flow stubbing, Arrange-Act-Assert structure, and clear test naming.
TDD patterns, test writing strategies, coverage guidance, mocking patterns. Use when: write tests, TDD, test coverage, unit test, integration test, E2E test, mocking, test organization, pytest, vitest, jest.
Test and troubleshoot Enable Banking sandbox integrations, ASPSP sandbox behavior, Mock ASPSP setup, sandbox credentials, AIS authorization simulation, transaction pagination quirks, and sandbox limitations. Use when Codex needs to choose a sandbox bank, find test credentials, explain why a sandbox ASPSP behaves differently from production, configure Mock ASPSP data, or implement project code that must work against Enable Banking sandbox environments.
Generates pytest test suites with happy path, edge cases, error conditions, fixture scaffolding, mocks, async patterns. Triggers on: "generate tests", "write tests for", "test this function", "create test suite", "pytest for", "unit tests for", "mock strategy for".
Testing best practices for the frontend. Emphasizes E2E tests over unit tests, minimal mocking, and testing behavior over implementation details. Use when writing tests or reviewing test code.
Use when building e2e tests with Playwright, under deadline pressure to ship incomplete coverage, or struggling with wait strategies and mock-vs-reality tradeoffs - provides patterns for edge case coverage, deterministic waits, and strategic mocking decisions
Testing patterns for Prowler SDK (Python). Trigger: When writing tests for the Prowler SDK (checks/services/providers), including provider-specific mocking rules (moto for AWS only).
Python testing with pytest, coverage, fixtures, parametrization, and mocking. Covers test organization, conftest.py, markers, async testing, and TDD workflows. Use when user mentions pytest, unit tests, test coverage, fixtures, mocking, or writing Python tests.
