coverage-server

Overview ¶

This is a helper for the tests of the coverage package, and handy for poking at the endpoints by hand. runtime/coverage, which the package is built around, only works in binaries built with go build -cover, never in a test binary. So the tests build and run this program to check that we serve coverage data which the go tools can digest.

Print the address of the server, then serve until terminated. Terminate with SIGTERM to get the coverage data written to $GOCOVERDIR, too.
