Cocov offers two services for repositories: Coverage monitoring, and issue detection. One component does not require the other, but enabling both will provide the complete experience.

Coverage Monitoring #

The platform is capable of receiving and interpreting coverage data from several coverage formats, and can keep information regarding those results for statistical data, and also to allow maintainers to automatically reject changes that does not keep the total coverage percentage above a certain limit.

Checks & You: How to Maintain Consistency and Security #

Along with Coverage Monitoring, Cocov also leverages well-known open-source tools to detect for style inconsistencies, security issues, and virtually any other aspect of your repository’s code as long as there’s a plugin for that task.

Detected issues can also be used to prevent pull-requests from being merged, ensuring, for instance, that new changes are always sent patching new or existing problems.

Preventing Collaborators from Bypassing Cocov Checks #

As Cocov relies on a single configuration file, it is possible for collaborators to change it in order to disable or alter how the platform behaves on a given repository. To prevent those changes, being they accidental or not, GitHub provides mechanisms to limit or ensure certain files are reviewed before PRs are merged. See more about that on Protecting the Manifest File.
