Do you consider test coverage in projects? How is it organized?

Test coverage is considered an important indicator of code quality, but not an end in itself. In projects, I usually organize coverage as follows:

• Use tools to measure coverage (for example, built-in Go go test -cover)
• Set a minimum coverage threshold for new features to prevent quality degradation
• Focus on covering critical and complex parts of the code, business logic
• Write both unit tests and integration tests to cover different levels
• Analyze coverage reports and add tests for important but uncovered parts

Example of running tests with coverage in Go:

go test ./... -coverprofile=coverage.out
 go tool cover -html=coverage.out

Thus, coverage helps control quality and reduce the risk of errors.
