This is the PHP port of Hamcrest Matchers ========================================= Hamcrest is a matching library originally written for Java, but subsequently ported to many other languages. hamcrest-php is the offical PHP port of Hamcrest and essentially follows a literal translation of the original Java API for Hamcrest, with a few Exceptions, mostly down to PHP language barriers: 1. instanceOf($theClass) is actually anInstanceOf($theClass) 2. both(containsString('a'))->and(containsString('b')) is actually both(containsString('a'))->andAlso(containsString('b')) 3. either(containsString('a'))->or(containsString('b')) is actually either(containsString('a'))->orElse(containsString('b')) 4. Unless it would be non-semantic for a matcher to do so, hamcrest-php allows dynamic typing for it's input, in "the PHP way". Exception are where semantics surrounding the type itself would suggest otherwise, such as stringContains() and greaterThan(). 5. Several official matchers have not been ported because they don't make sense or don't apply in PHP: - typeCompatibleWith($theClass) - eventFrom($source) - hasProperty($name) ** - samePropertyValuesAs($obj) ** 6. When most of the collections matchers are finally ported, PHP-specific aliases will probably be created due to a difference in naming conventions between Java's Arrays, Collections, Sets and Maps compared with PHP's Arrays. Usage ----- To use Hamcrest, add the hamcrest directory to your include path and then simply include hamcrest.php to gain access to each of the Hamcrest matchers. <?php set_include_path( 'hamcrest-php/hamcrest' . PATH_SEPARATOR . get_include_path() ); require_once 'hamcrest.php'; assertThat('a', equalToIgnoringCase('A')); ?> hamcrest.php uses global function names. If you really need namespaced ones (which won't look as fluent), include "hamcrest/Hamcrest/Matchers.php" and "hamcrest/Hamcrest/MatcherAssert.php". <?php set_include_path( 'hamcrest-php/hamcrest' . PATH_SEPARATOR . get_include_path() ); require_once 'hamcrest/Hamcrest/MatcherAssert.php'; require_once 'hamcrest/Hamcrest/Matchers.php'; Hamcrest_MatcherAssert::assertThat('a', Hamcrest_Matchers::equalToIgnoringCase('A')); ?> PEAR Package ------------ You can now install Hamcrest using PEAR. Note that the channel is lowercase while the package is uppercase. > pear channel-discover hamcrest.googlecode.com/svn/pear > pear install hamcrest/Hamcrest Assuming you have PEAR's library installation directory (e.g. /usr/bin/php) in your global include path, you only need to include hamcrest.php. <?php require_once 'Hamcrest/hamcrest.php'; assertThat('a', equalToIgnoringCase('A')); ?> ** [Unless we consider POPO's (Plain Old PHP Objects) akin to JavaBeans] - The POPO thing is a joke. Java devs coin the term POJO's (Plain Old Java Objects).
