Composer installation

Composer is a dependency manager for PHP projects. It installs PHP libraries into /vendor/ subdirectory inside your moodle dirroot.

1. install Composer - http://getcomposer.org/doc/00-intro.md
2. install PHUnit and dependencies - go to your Moodle dirroot and execute php composer.phar install

Configure your server

You need to create a new dataroot directory and specify a separate database prefix for the test environment, see config-dist.php for more information.

• add $CFG->phpunit_prefix = 'phpu_'; to your config.php file
• and $CFG->phpunit_dataroot = '/path/to/phpunitdataroot'; to your config.php file

Initialise the test environment

Before first execution and after every upgrade the PHPUnit test environment needs to be initialised, this command also builds the phpunit.xml configuration files.

• execute php admin/tool/phpunit/cli/init.php

Execute tests

• execute vendor/bin/phpunit from dirroot directory
• you can execute a single test case class using class name followed by path to test file vendor/bin/phpunit lib/tests/phpunit_test.php
• it is also possible to create custom configuration files in xml format and use vendor/bin/phpunit -c mytestsuites.xml

How to add more tests?

1. create tests/ directory in your add-on
2. add test file, for example local/mytest/tests/my_test.php file with my_test class that extends basic_testcase or advanced_testcase
3. set the test class namespace to that of the class being tested
4. add some test_*() methods
5. execute your new test case vendor/bin/phpunit local/mytest/tests/my_test.php
6. execute php admin/tool/phpunit/cli/init.php to get the plugin tests included in main phpunit.xml configuration file

Windows support

• use \ instead of / in paths in examples above
