PHPUnit is a testing framework that is strongly supported by zend. It ensures project quality during high-quality unit testing, and can effectively reduce bugs and improve programs.
Install PHPUnit:
In the php directory:
Copy the codeThe code is as follows:
pear channel-discover pear;
pear install phpunit/PHPUnit
In Windows, add the PHP environment variable to the PATH environment variable.
Simple use:
Copy the codeThe code is as follows:
<?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));
}
}
From the above, you can see the basic rules for writing PHPUnit:
(1) Class Class test is written in ClassTest
(2) ClassTest inherits PHPUnit_Framework_TestCase
(3) The test methods are all in the test* format, and they can also be marked as test methods through @test.
(4) Assert the actual value and the expected value through the assert method assertEquals.
