Setting up
----------
1. Clone this git repository on your local machine.
2. Install [Composer](https://getcomposer.org/) if you don't already have it.
2. Run `composer install` to fetch all the dependencies.
3. Run `./bin/wp --info` to test if everything was installed properly.
Submitting patches
------------------
Whether you want to fix a bug or implement a new feature, the process is pretty much the same:
0. [Search existing issues](https://github.com/wp-cli/wp-cli/issues); if you can't find anything related to what you want to work on, open a new issue so that you can get some initial feedback.
1. [Fork](https://github.com/wp-cli/wp-cli/fork) the repository.
2. Create a branch for each issue you'd like to address. Commit your changes.
3. Push the code changes from your local clone to your fork.
4. Open a pull request.
It doesn't matter if the code isn't perfect. The idea is to get it reviewed early and iterate on it.
If you're adding a new feature, please add one or more functional tests for it in the `features/` directory. See below.
Lastly, please follow the [WordPress Coding Standards](http://make.wordpress.org/core/handbook/coding-standards/).
Running and writing tests
-------------------------
There are two types of automated tests:
* unit tests, implemented using [PHPUnit](http://phpunit.de/)
* functional tests, implemented using [Behat](http://behat.org)
### Unit tests
The unit test files are in the `tests/` directory.
To run the unit tests, just execute:
./vendor/bin/phpunit
### Functional tests
The functional test files are in the `features/` directory.
Before running the functional tests, you'll need a MySQL user called `wp_cli_test` with the password `password1` that has full privileges on the MySQL database `wp_cli_test`. Running the following as root in MySQL should do the trick:
GRANT ALL PRIVILEGES ON wp_cli_test.* TO "wp_cli_test"@"localhost" IDENTIFIED BY "password1";
Then, to run the entire test suite:
./vendor/bin/behat --expand
Or to test a single feature:
./vendor/bin/behat features/core.feature
More info can be found by using `./vendor/bin/behat --help`.

Thanks! Hacking on WP-CLI should be fun. If you find any of this hard to figure out, let us know so we can improve our process or documentation!
