The testing pyramid and why you shouldn’t use it

The author of the text discusses the testing pyramid and its limitations, arguing that it does not provide a balanced approach to testing. Instead, they propose a more nuanced approach where unit tests are used sparingly for isolated logic, integration tests are the general default, and end-to-end (E2E) tests are used to replace manual QA steps and document behavioral decisions. The author also criticizes the test pyramid's emphasis on unit tests, arguing that it leads to wasted effort and unnecessary code duplication. In contrast, a balanced approach prioritizes E2E tests for replacing manual QA, integration tests for general testing, and unit tests only when necessary for isolated logic. This approach aims to maximize the benefits of each type of test while minimizing their drawbacks.
