What is the level of test coverage in your project in percentage?

The level of code test coverage in a project depends on the requirements and practices of the team. Usually, they aim for at least 70-80% coverage to ensure sufficient functionality testing.

However, it is important not only to the number of covered lines but also the quality of tests — they should check different scenarios and boundary cases.

In some projects, coverage may be lower (for example, 50-60%) due to time constraints or testing complexity, while in others it may be higher than 90% for critical systems.

To measure coverage, tools like JaCoCo are often used, which show the percentage of covered lines, branches, and methods.
