When you maintain an open-source project it is considered a good practice to have a high test coverage, so the community can feel safe about using your code in their projects. There are some services that can analyze your code quality and provide some feedback about it. One of the most popular is Code Climate. This service doesn’t run your tests, but you can use one of CI tools to run them and then send their result to Code Climate. This article will show how to use Travis CI to run your tests and CodeClimateto get your test coverage.


1. Get Your CodeClimate Reporter ID

On CodeClimate side you need only a reporter ID. Go to your repository setting, then select “Test Coverage”.


2. Add Your Code Climate Token To Travis CI

The next step is to add your token to your travis.yml file. But don’t rush to do it right away! It is a secret token, don’t commit it to your repository. At first, you should encrypt it with Travis CI Client. It is a ruby gem that includes both a command line client and a Ruby library to interface with a Travis CI service.

2.1 Install Travis CI Client

It is a simple ruby gem, so to install it, run in your terminal:


2.2 Login To Travis CI Client

Then, you need to login. Run travis login and provide you GitHub credentials:


2.3 Encrypt CodeClimate Token

Now, we can encrypt your CodeClimate token with travis encrypt command:


Copy everything in double quotes after secure:, it is your encrypted token.

2.4 Add Encrypted Token To Travis CI Config

The last step is to add your repository encrypted token to travis.yml file like this:

      secure: "pdpKV..."

3. Add CodeClimate Test Reporter Package

I assume that you are testing PHP package, so we need to add CodeClimate test reporter as a dev dependency to our project:

composer require codeclimate/php-test-reporter --dev

4. Update phpunit.xml

We need manually collect tests report before sending it to CodeClimate. Add this section to your phpunit.xml file to collect coverage data to build folder in the root of your project:

        <log type="coverage-clover" target="build/logs/clover.xml"/>

Also, you can add this folder to your .gitignore file.

5. Update Travis CI Config To Send A Report

Add this section to your travis.yml to execute CodeClimate reporter, after your tests have been executed:

  - vendor/bin/test-reporter

That Is All!

Next time when your push a build on Travis CI, it will run your tests and then send coverage report to CodeClimate.


Now you can also add some CodeClimate badges to your repo’s README file:
