This tool follows PSR-2 Coding standard.
My development workflow make use of grunt watch plugin, that will run phpunit automatically after each file save. Grunt is also used to generate the test coverage.
All pull request should not break existing tests. You're more than welcome to write additional tests. There is a grunt task to run the tests :
grunt phpunit
Without grunt, just run :
phpunit tests
Or you can also run tests after each file edition :
grunt watch
Use the coverage grunt task to generate code coverage.
grunt coverage
Without grunt, use :
phpunit tests
The coverage reports is in build/coverage/index.html.
