What is a Test Double? | Types & Best Practices
This blog reviews the article “What is a Test Double? | Types & Best Practices”, by Ritika Kumari.
This article on Test Doubles provides a comprehensive overview of their role in software testing. It emphasizes how test doubles act as substitutes for real components, enabling developers to test code in isolation without relying on dependencies. The article highlights the importance of test doubles in scenarios where dependencies are unavailable, incomplete, or unsuitable for testing environments.
Kumari also discusses the various types of test doubles, including mocks, stubs, spies, fakes, and dummies, each serving unique purposes in the testing process. She provides practical examples, such as using a test double for a payment gateway API to simulate responses like successful payments, failures, or network errors.
I think this was a well made article that does a nice job at explaining the usefulness of Test Doubles. I learned that they give you more control, flexibility, and reliability in your testing efforts.
