# Github Communication Tips

 - Don’t be afraid to mention people (@username) who are knowledgeable on the topic or invested. We are academics and overcommitted, it’s too easy for issues to go unanswered: don’t give up on us!
 - Likewise, don’t be shy about bumping an issue if no one responds after a few days. Balancing responsibilities is hard.
 - Want to get more involved? Issues marked with “Good beginner issue” are a good place to start if you want to try your hand at submitting a PR.
 - Everyone is encouraged/welcome to comment on the issue queue! Tell us if you
     - are experiencing the same problem
     - have tried a suggested fix
     - know of a potential solution or work-around
     - have an opinion, idea or feedback of any kind!
 - Be kind when interacting with others on Github! (see Code of Conduct below for further guidelines). We want to foster a welcoming, inclusive community!
     - Constructive criticism is welcome and encouraged but should be worded such that it is helpful :-) Direct criticism towards the idea or solution rather than the person and focus on alternatives or improvements.

# Code of Conduct

Be nice! If that’s insufficient, Tripal community defers to https://www.contributor-covenant.org/

# Required Dependencies
* Drupal:
  * Drupal 7.x
  * Drupal core modules: Search, Path and PHP modules.
  * Drupal contributed modules:
    * [Views](http://drupal.org/project/views)
    * [Entity API](http://drupal.org/project/entity)
* PostgreSQL 9.3 or higher (9.5 required for Chado 1.2 to 1.3 upgrade)
* PHP 5.5+
* UNIX/Linux

# Development Testing

To run PHP unit tests on your local system, run `composer install` to install developer-specific requirements.  Next, create a `.env` file in your `/Tests/` directory that defines the `DRUPAL_ROOT` variable, for example

```
DRUPAL_ROOT=/var/www/html
```
Then run PHPUnit from your root Tripal directory.

PHPUnit tests will also be run in the Travis CI build.

Read our [testing guidelines](https://tripal.readthedocs.io/en/latest/contributing/tests.html).
