About this chapter
What this chapter covers
A pipeline that deploys without testing is only a faster way to break production. This chapter is part of the build and release pipelines domain, worth 50 to 55 percent of the exam in total. It covers the gates that stop bad changes, the test types a good strategy includes, how to run tests and publish results in a pipeline, and how to measure code coverage.
The key skill is placing the right test or gate at the right point: fast checks early, expensive checks later, and human or automated approvals before production.
How the topics fit together
- Quality gates and release gates covers the checks that decide whether a change may continue.
- Testing strategy, test tasks and code coverage covers test types, running tests in pipelines and coverage.
Put the cheapest, fastest tests first. A unit test failure should stop the run before a slow environment is created.
