rebar3_codecov

A rebar3 plugin which converts .coverdata files to JSON format, compatible with https://codecov.io.

Use

Add the plugin to your rebar config, register it as a post-hook and enable code coverage.

{plugins, [
    {rebar3_codecov, "0.4.0"}
]}.

{provider_hooks,
 [
  %% Use ct, eunit, or both if you test your project with both frameworks.
  {post, [{ct, {codecov, analyze}}]},
  {post, [{eunit, {codecov, analyze}}]}
 ]}.

{cover_enabled, true}.

Configure Travis according to https://docs.travis-ci.com/user/getting-started/

The minimum .travis.yml should look more or less like the following:

language: erlang

otp_release:
    - 20.3

script:
    rebar3 ct

install:
    travis_retry pip install --user codecov

after_success:
    codecov

Alternatively, you can call the plugin directly.

rebar3 codecov analyze path="_build/test/cover"

By default the plugin will look for the *.coverdata files in _build/test/cover directory. If you want to specify a different location, add to your rebar.config the list of directories

{codecov_opts,
 [
  {path, ["path/to/*.coverdata/files"]}
 ]}.

Go to https://codecov.io and add your repository to see the results of code coverage
