PHPUnit Installation and Use Examples

PHPUnit is a testing framework supported by zend. High-quality unit testing is the basis of ensuring project quality, which can effectively reduce BUG and improve procedures.

Install PHPUnit:

Under the directory of php:

pear channel-discover pear;

pear install phpunit/PHPUnit

Under windows, add the environment variable of php to the environment variable of PATH.
Easy to use:

<?php

class StackTest extends PHPUnit_Framework_TestCase

{

 

    public function testArray()

    {

        $stack = array();

        $this->assertEquals(0, count($stack));

 

        array_push($stack, 'foo');

        $this->assertEquals('foo', $stack[count($stack)-1]);

        $this->assertEquals(1, count($stack));

 

        $this->assertEquals('foo', array_pop($stack));

        $this->assertEquals(0, count($stack));

    }

    

    /**

     * @test

     */

    public function Stringlen()

    {

        $str = 'abc';

        $this->assertEquals(3,  strlen($str));

    }

}

You can see the basic rules of writing PHPUnit from the above:
(1) Tests of class Class are written in ClassTest
(2) ClassTest inherits PHPUnit_Framework_TestCase
(3) The test methods are all in test * format, which can also be labeled as test methods through @ test.
(4) The actual and expected values are asserted by the assertion method assertEquals.
