What is the minimum test coverage percentage your team applies to ensure code quality?.

The minimum test coverage percentage in a team depends on quality requirements and project specifics, but generally, to ensure a basic level of code reliability, a coverage of at least 70-80% is recommended.

It is important to understand that a high coverage percentage does not always guarantee quality — it is more important to cover critical and complex parts of the code, as well as to write meaningful tests.

In some teams, a coverage threshold is set, for example, 80%, and code with lower coverage is not allowed to be merged. In other cases, the threshold may be lower if the project is small or testing is difficult.

An example of setting coverage in Go (using go test):

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

Here, you can see the coverage percentage and decide whether the tests are sufficient.
