Overview ¶
Package cover contains glue infrastructure code for collecting and serving live code-coverage data from a process. The package gets pulled-in implicitly from an instrumented binary and registers a topic in Ctrlz that allows snapshotting, clearing of code coverage state, as well as the ability to download a coverage profile file.
