Frequently Asked Questions about testing-patterns

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the testing pyramid and how should I distribute unit and integration tests?

The AAA pattern structures tests into Arrange, Act, and Assert phases, ensuring your test logic remains clear, isolated, and maintainable across both unit and integration testing scenarios.

When should I use mocking strategies like stubs, spies, and mocks in my tests?

Use mocking strategies like stubs, spies, and mocks to isolate components during unit testing, ensuring tests remain fast and self-checking without relying on external dependencies or complex integration setups.

What are common software testing anti-patterns and how do I avoid them?

Common testing anti-patterns include slow execution, shared state between tests, and unclear assertions; avoiding them involves following structured patterns for test organization, data management, and isolated testing.

How do I select the right test type for a new software feature?

Select test types by evaluating feature scope: use unit tests for isolated logic, integration tests for module interactions, and end-to-end tests for critical user paths to ensure high code coverage and maintainability.

What are the best practices for test organization and data management?

Test organization best practices involve consistent naming conventions, logical grouping by feature, and isolated test data management to create fast, repeatable, and timely test suites that are easy to maintain.
