Google has spent more than a decade attempting to refine their coverage infrastructure and validate the most suitable approach.Ĭovering code with tests can be time-consuming and, therefore, costly. And it’s almost impossible to achieve high code coverage in a large-scale project with complicated logic that can lead to multiple errors. It’s easier to cover more code with unit tests in small and mid-sized projects - and when using test automation. They also won’t report on the absence of features that should have been implemented.Īnother crucial thing is to understand when you should concentrate on a high coverage percentage and when you shouldn’t. It’s essential to remember that code coverage results can’t point to flaws in the logic of your code. 80% coverage is also a decent result, but there’s a risk that this 80% won’t cover the main scenario. Even an empty method can be 100% covered, but this code is useless. One of the biggest challenges related to code coverage is interpreting the results.Ĭomplete code coverage doesn’t mean that a project is fully tested. You can find commercial and open-source tools to automate the measuring process.ĭespite its advantages, measuring code coverage isn’t a silver bullet for checking code efficiency. After that, your code coverage score can change and direct your attention to a potential bug or another issue. If you change a method, the test can fail. Passing tests shows that correct performance is possible, but only for a certain set of input parameters. Adjust tests to check various sets of input parameters.Such code can potentially be dead or useless - or contain bugs. When analyzing code coverage results, you can find areas of the program that were left unattended during testing. Prevent defects at early project stages.If code coverage results aren’t satisfying and the percentage of non-covered code is too high, you can add more unit tests to improve the score.
