-3. Add a `.codecov.yml` file to your project root to specifiy what codecov.io's script should ignore:
-
-```yaml
-ignore:
-  - "**/test/.*"
-```
-
 Then you can use the `code-coverage` test and it will run the script provided by [codecov.io](codecov.io) which runs `gcov` to generate the reports and then compiles them into a report and uploads them to their servers.
 
 If you are using this on a private github repo you will need to set the `CODECOV_TOKEN` enviroment variable in the `global` section of your `.travis.yml` file to the value you can find on the settings page of your project on codecov.io.
