Milline on kõige vastuvõetavam kooditestimise katvuse tase tõhusa tarkvaratootega kontrollimiseks?

The optimal level of code test coverage depends on the project, but it is generally considered good practice to aim for coverage in the 70-90% range for effective verification.

• Less than 70% may indicate that important parts of the code are not tested, increasing the risk of errors.
• Coverage above 90% often requires excessive effort and can lead to testing trivial details, reducing efficiency.

It's not just about the amount of code covered, but also the quality of tests: they should verify key logic, boundary cases, and possible errors.

Therefore, aim for a balance between sufficient coverage and reasonable costs in writing and maintaining tests.
