Which of the following statements about the test pyramid is TRUE?

The correct answer is B. The higher the layer of the test pyramid, the more production code a single automated test within. The test pyramid concept suggests that there should be more low-level tests (unit tests) and fewer high-level tests (end-to-end tests). As we move higher up the pyramid (e.g., from unit tests to integration tests to end-to-end tests), each test covers more production code…

Explanation

The test pyramid concept suggests that there should be more low-level tests (unit tests) and fewer high-level tests (end-to-end tests). As we move higher up the pyramid (e.g., from unit tests to integration tests to end-to-end tests), each test covers more production code. Higher-level tests (like end-to-end) validate larger parts of the application, including multiple units and their interactions. This aligns with the principle that higher-level tests provide broader coverage but are fewer in number and more expensive to run and maintain.
