Unit tests

Setup your environment for tests

The framework used is PHPUnit; it can be installed with Composer, which is a dependency management tool.

Install composer

You can either use:

a system-wide version, e.g. installed through your distro's package manager
a local version, downloadable here.

# system-wide version
$ composer install
$ composer update

# local version
$ php composer.phar self-update
$ php composer.phar install
$ php composer.phar update

Install Shaarli dev dependencies

$ cd /path/to/shaarli
$ composer update

Install and enable Xdebug to generate PHPUnit coverage reports

See http://xdebug.org/docs/install

For Debian-based distros:

$ aptitude install php5-xdebug

For ArchLinux:

$ pacman -S xdebug

Then add the following line to /etc/php/php.ini:

zend_extension=xdebug.so

Run unit tests

Test results and coverage

By default, PHPUnit will run all suitable tests found under the tests directory.

Each test has 3 possible outcomes:

. - success
F - failure: the test was run but its results are invalid
- the code does not behave as expected
- dependencies to external elements: globals, session, cache...
E - error: something went wrong and the tested code has crashed
- typos in the code, or in the test code
- dependencies to missing external elements

If Xdebug has been installed and activated, two coverage reports will be generated:

a summary in the console
a detailed HTML report with metrics for tested code
- to open it in a web browser: firefox coverage/index.html &

Executing specific tests

Add a @group annotation in a test class or method comment:

/**
 * Netscape bookmark import
 * @group WIP
 */
class BookmarkImportTest extends PHPUnit_Framework_TestCase
{
   [...]
}

To run all tests annotated with @group WIP:

$ vendor/bin/phpunit --group WIP tests/
