DEPENDENCIES phpUnit runs on PHP3 or PHP4. phpUnit uses PCRE (Perl Compatible Regular Expressions). PCRE is normally compiled into PHP, but it might be missing from custom builds of PHP. INSTALLATION Place the phpunit.php file so that it is in the PHP include_path for the PHP code to be tested. Installing it in the same directory as the code-under-test should work. The same phpunit.php file can be shared by any number of test suites. You may wish to install phpunit.php in just one place and adjust the PHP include_path to include that place. EXAMPLES The self-test suite for phpUnit itself is currently the best (only) example distributed with phpUnit. See phpunit_test.php.
