First of all, you need PEAR to install PHPUnit.
pacman -S php-pear
Now you can do just like the official documentation. As root (sudo will NOT be enough, You'll have to do this as "real" root), just type
pear config-set auto_discover 1 pear install pear.phpunit.de/PHPUnit
Notice that you might have to run following command before start to install phpunit
For running PHPUnit properly you must have the /usr/bin/ directory listed in the open_basedir option at the /etc/php/php.ini
open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/bin/
Or just unset it
With some PHP frameworks, you might get the error of missing Selenium. Just install the selenium package with pear (make sure you have root rights)
pear install phpunit/PHPUnit_Selenium
This section gives beginners a very brief introduction to how to use PHPUnit to run test cases. It won't explain how to write them but if you want to get more information about this have a look at the references.
As the application to be tested we use in this example a JSON schema validator. In the directory tests you'll see the directory mock and three files.
mock contains JSON schemas which have nothing to do with PHPUnit itself, it's application-specific here, you won't find it in other applications.
phpunit.xml is a configuration file where you
- configure PHPUnit's core functionality,
- compose a test suite out of test suites and test cases,
- select groups of tests from a suite of tests that should (not) be run,
- configure the blacklist and whitelist for the code coverage reporting,
- configure the logging of the test execution,
- attach additional test listeners to the test execution,
- configure PHP settings, constants, and global variables or
- configure a list of Selenium RC servers.
In bootstrap.php you put code to be run before tests are executed. Here you could register your autoloading functions or include other php scripts. Though there's one limitation, only one bootstrap can be defined per PHPUnit configuration file.
JsonValidatorTest.php is the PHP file with the test cases. It's beyond the scope to explain the content of this file in depth. As a beginner you are most likely interested in how to run the test cases so what you need to execute is simply
phpunit JsonValidatorTest JsonValidatorTest.php
You pass it the class with the test cases and the file where they're defined. That's it.
