Many modern code coverage tools track and report code coverage data generated from running tests during continuous integration. They report code coverage data through a variety of channels, including email, Slack, Mattermost, or through the web interface of social coding platforms such as GitHub. In fact, this ensemble of tools can be configured in such a way that the software engineer gets a failing status check when code coverage drops below a certain threshold. In this study, we broadly investigate the opinions and experience with code coverage tools through a survey among 279 software engineers whose projects use the Codecov coverage tool and bot. In particular, we are investigating why software engineers would ignore a failing status check caused by drop in code coverage. We observe that >80% of software engineers-at least sometimes-ignore these failing status checks, and we get insights into the main reasons why software engineers ignore these checks.
