Overview ¶

Package coverage serves the coverage data of a plugin built with coverage instrumentation, using make COVER=1, over the instrumentation HTTP server. It lets tests which run a plugin as a whole, in a cluster, collect coverage data from it the way go test -cover does for unit tests. Our e2e tests use this to take a snapshot of the counters per test case.

Save the served data to files named covmeta.<id> and covcounters.<id>.N.M, with <id> from the ID endpoint, and go tool covdata can digest the result. A plugin built without instrumentation serves an error for all endpoints.
