A team building a website needs more than working code: it needs confidence that the code meets requirements and that defects are found before release. Testing checks software behavior during implementation, while defect triage helps the team decide what to fix. Engineering managers make room for both as part of project execution. section 10.1.4
Choose tests according to what needs checking:
- Unit tests check a small piece of code, such as a method or function. Make them part of the definition of done for development tasks. section 12.2.2
- Integration tests check whether combined components interact correctly. section 12.2.2
- End-to-end tests simulate real-world use of the whole application. They are slower and cost more to maintain than other testing approaches. section 12.2.2
- Load tests generate production-like traffic from sample customers to reveal bottlenecks, single points of failure, and problems handling peak use. section 12.2.2
The test automation pyramid helps the engineering team produce high-quality software. It works at three levels: unit testing (base step), integration testing (middle step)m and end-to-end testing (top).
The test automation pyramid places unit tests at the base, integration tests in the middle, and end-to-end tests at the top. Use it to distinguish the scope of these three approaches. section 12.2.2
Test coverage helps reveal where testing may be thin. Line, branch, and method coverage measure different parts of the code exercised by tests. High coverage can increase confidence and support early defect detection, but it does not guarantee bug-free software. Monitor it as a signal for improvement, not as proof that testing is finished. section 12.2.2
A release check
For a website expected to meet defined requirements and accessibility standards, an engineering manager can check that developers include unit tests, review coverage for gaps, and coordinate testing and defect triage before release. Ask which behaviors still lack a convincing check rather than relying on a coverage number alone. section 10.1.4 section 12.2.2
