1### Setup your environment for tests
2
3The framework used is [PHPUnit](https://phpunit.de/); it can be installed with [Composer](https://getcomposer.org/), which is a dependency management tool.
4
5### Install composer
6
7You can either use:
8
9- a system-wide version, e.g. installed through your distro's package manager
10- a local version, downloadable [here](https://getcomposer.org/download/).
11
12```bash
13# system-wide version
14$ composer install
15$ composer update
16
17# local version
18$ php composer.phar self-update
19$ php composer.phar install
20$ php composer.phar update
21```
22
23#### Install Shaarli dev dependencies
24
25```bash
26$ cd /path/to/shaarli
27$ composer update
28```
29
30#### Install and enable Xdebug to generate PHPUnit coverage reports
31
32See http://xdebug.org/docs/install
33
34For Debian-based distros:
35```bash
36$ aptitude install php5-xdebug
37```
38For ArchLinux:
39```bash
40$ pacman -S xdebug
41```
42
43Then add the following line to `/etc/php/php.ini`:
44```ini
45zend_extension=xdebug.so
46```
47
48#### Run unit tests

119#### Test results and coverage
120
121By default, PHPUnit will run all suitable tests found under the `tests` directory.
122
123Each test has 3 possible outcomes:
124
125- `.` - success
126- `F` - failure: the test was run but its results are invalid
127 - the code does not behave as expected
128 - dependencies to external elements: globals, session, cache...
129- `E` - error: something went wrong and the tested code has crashed
130 - typos in the code, or in the test code
131 - dependencies to missing external elements
132
133If Xdebug has been installed and activated, two coverage reports will be generated:
134
135- a summary in the console
136- a detailed HTML report with metrics for tested code
137 - to open it in a web browser: `firefox coverage/index.html &`
138
139### Executing specific tests
140
141Add a [`@group`](https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.group) annotation in a test class or method comment:
142
143```php
144/**
145 * Netscape bookmark import
146 * @group WIP
147 */
148class BookmarkImportTest extends PHPUnit_Framework_TestCase
149{
150 [...]
151}
152```
153
154To run all tests annotated with `@group WIP`:
155```bash
156$ vendor/bin/phpunit --group WIP tests/
157```
