"coverage combine" should error if no coverage · Issue #412 · nedbat/coveragepy (original) (raw)

Originally reported by meejah (Bitbucket: meejah, GitHub: meejah)

If you run "coverage combine" and there is no .coverage file (or .coverage.* files) it will run without error and produce a .coverage that is "empty" (i.e. has the comment and then an empty dict).

It seems more intuitive that it should be an error to try and combine nothing.
