go-carpet - show test coverage for Go source files

To view the test coverage in the terminal, just run go-carpet.

It works outside of the GOPATH directory. And it works recursively for multiple packages.

With -256colors option, shades of green indicate the level of coverage.

By default skip vendor directories (Godeps,vendor), otherwise use -include-vendor option.

The -mincov option allows you to specify a coverage threshold to limit the files to be displayed.

Usage

  -256colors
    	use more colors on 256-color terminal (indicate the level of coverage)
  -args string
    	pass additional arguments for go test
  -file string
    	comma-separated list of files to test (default: all)
