roveralls

A Go recursive coverage testing tool.

GoDoc Build Status Build status Coverage Status Go Report Card

roveralls runs coverage tests on a package and all its sub-packages. The coverage profile is output as a single file called 'roveralls.coverprofile' for use by tools such as goveralls.

This tool was inspired by github.com/go-playground/overalls written by Dean Karn, but I found it difficult to test and brittle so I decided to rewrite it from scratch. Thanks for the inspiration Dean.

Usage

At its simplest, to test the current package and sub-packages and create a roveralls.coverprofile file in the directory that you run the command:

$ roveralls

To see the help for the command:

$ roveralls -help

    roveralls runs coverage tests on a package and all its sub-packages.  The
    coverage profile is output as a single file called 'roveralls.coverprofile'
    for use by tools such as goveralls.

    Usage of roveralls:
      -covermode count,set,atomic
          Mode to run when testing files: count,set,atomic (default "count")
      -help
          Display this help
      -ignore dir1,dir2,...
          Comma separated list of directory names to ignore: dir1,dir2,... (default ".git,vendor")
      -short
          Tell long-running tests to shorten their run time
      -v	Verbose output

View Output in a Web Browser

To view the code coverage for you packge in a browser:

$ go tool cover -html=roveralls.coverprofile

Use with goveralls

The output of roveralls is the same as the the standard go test -coverprofile=profile.coverprofile but with multiple files tested in the output file. This can therefore be used with tools such as goveralls.

If you wanted to call it from a .travis.yml script you could use:

- $HOME/gopath/bin/roveralls
- $HOME/gopath/bin/goveralls -coverprofile=roveralls.coverprofile -service=travis-ci
