Using Codecov

Codecov.io is another test-coverage tracking tool that integrates with your continuous integration servers (e.g. TravisCI) or with HTTP POSTs from your very own computer at home.

Using Coverage.jl with Codecov.io?

1. Enable Codecov.io for your repository. If it is public on GitHub and you are using using TravisCI, this is all you need to do. You can sign into Codecov using your Github identity. You will be served a REPO_TOKEN. You'll need this if you're not using a CI solution.
2. You must be using Julia 0.3 or higher, which added the --code-coverage command line argument.
3. Use the command line option when you run your tests

• Either with something like julia --code-coverage test/runtests.jl, or
• with something like julia -e 'Pkg.test("MyPkg", coverage=true)'

4. Add the following to the end of your .travis.yml file. This line downloads this package, collects the per-file coverage data, then bundles it up and submits to Codecov. Coverage.jl assumes that the working directory is the package directory, so it changes to that first (so don't forget to replace MyPkg with your package's name!

after_success:
- julia -e 'cd(Pkg.dir("MyPkg")); Pkg.add("Coverage"); using Coverage; Codecov.submit(Codecov.process_folder())'

If you're running coverage at home and want to upload results to Codecov, make a bash script like the following:

#!/bin/bash
REPO_TOKEN=$YOUR_TOKEN_HERE julia -e 'cd(Pkg.dir("MyPkg")); using Coverage;  Codecov.submit_token(Codecov.process_folder())'
