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

116 | #### Test results and coverage | ||
117 | |||
118 | By default, PHPUnit will run all suitable tests found under the `tests` directory. | ||
119 | |||
120 | Each test has 3 possible outcomes: | ||
121 | * `.` - success | ||
122 | * `F` - failure: the test was run but its results are invalid | ||
123 | * the code does not behave as expected | ||
124 | * dependencies to external elements: globals, session, cache... | ||
125 | * `E` - error: something went wrong and the tested code has crashed | ||
126 | * typos in the code, or in the test code | ||
127 | * dependencies to missing external elements | ||
128 | |||
129 | If Xdebug has been installed and activated, two coverage reports will be generated: | ||
130 | * a summary in the console | ||
131 | * a detailed HTML report with metrics for tested code | ||
132 | * to open it in a web browser: `firefox coverage/index.html &` | ||
133 | |||
134 | ### Executing specific tests | ||
135 | |||
136 | Add a [`@group`](https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.group) annotation in a test class or method comment: | ||
137 | |||
138 | ```php | ||
139 | /** | ||
140 | * Netscape bookmark import | ||
141 | * @group WIP | ||
142 | */ | ||
143 | class BookmarkImportTest extends PHPUnit_Framework_TestCase | ||
144 | { | ||
145 | [...] | ||
146 | } | ||
147 | ``` | ||
148 | |||
149 | To run all tests annotated with `@group WIP`: | ||
150 | ```bash | ||
151 | $ vendor/bin/phpunit --group WIP tests/ | ||
152 | ``` | ||
