# Unit Tests for [YOURLS](https://github.com/YOURLS/YOURLS/)

## About

This is the unit test suite for YOURLS: a collection of hundreds of tests to make sure that whenever something in YOURLS is added, changed or removed, everything still works under all the supported PHP versions.

## Getting Started

If you want to run tests locally:

0. Install PHPUnit.
   ```bash
   composer -d tests/ install
   ```
1. Create an empty MySQL database and user. **Do not use an exisiting database** or you will lose data, guaranteed.
3. Copy `<YOURLS_ROOT>tests/data/config/yourls-tests-config-sample.php` to `<YOURLS_ROOT>/tests/yourls-tests-config.php` and edit it to match your setup.
   ```bash
   cp tests/data/config/yourls-tests-config-sample.php tests/yourls-tests-config.php
   ```
4. In YOURLS root directory, you can now run the shell command:
   ```bash
   composer -d tests/ run test -- --configuration=../phpunit.xml.dist ..
   ```

Hopefully you should see something like the following appear:

OK (519 tests, 1123 assertions)
```

You can elect to run only selected groups of tests, eg:

```bash
$ phpunit --group formatting
```

See each `@group` directive in selected tests.

PHPUnit supports both `phpunit.xml` and `phpunit.xml.dist`, where `phpunit.xml` has higher priority:
if you want to specify your own settings, copy `phpunit.xml.dist` to `phpunit.xml` and edit that file.
