Usage

There are 2 ways to use gocovr:

1. in place of golang's go test
2. a replacement for opening a browser to view coverage

gocovr test

Running gocovr test will run go test with an added -coverprofile. Any arguments following test are transparently passed through to go test.

To run on multiple packages, just run something like gocovr test ./... github.com/some/package.

gocovr [cover.out]

Running gocovr will interpret a cover.out file by default; you may pass in any other file to parse.

Arguments

• -showCovered: print files that have 100% coverage

Skipping

Sometimes you have files that you just don't need to test, and you want to skip them. To do this, add the following line, on its own line, before the first import statement.

//gocovr:skip-file
