PHPUnit Introductory Article ____php

what PHPUnit is.

It is a lightweight PHP test framework

why to use PHPUnit.

1. Facebook is using

2. You can manipulate the test script by command

3. Can test performance

4. Can test code coverage

5. Can automatically update the parameter data of test cases

6. Various formats of the log

6. The most important thing is that the function is so dazzling, it is very simple to use

Quick Start

<?php
require_once ' phpunit/framework.php ';
 
Class Arraytest extends Phpunit_framework_testcase
{public
    function Testnewarrayisempty ()
    {
        // Creates an array fixture.
        $fixture = Array ();
 
        The size of the assertion array fixture is 0.
        $this->assertequals (0, sizeof ($fixture));
    }
? >

1. Arraytest for Test class

2. Arraytest inherited from Phpunit_framework_testcase

3. Test method Testnewarrayisempty (), the test method must be public permission, usually beginning with test, or you can optionally give it a comment @test to indicate that the function is a test function

/**
* @test
/Public Function testnewarrayisempty ()
{
     $fixture = array ();
     $this->assertequals (0, sizeof ($fixture));

command line start test

PHPUnit the test file name, where you want to test the arraytest.php file

Advanced Features

Are you tired of having to put a test in front of each test method name, or not to write multiple test cases because it's just a different parameter? My favorite advanced features, now grandly recommended to you, called Frame Builder

<?php
class Calculator
{public
    function add ($a, $b)
    {return
        $a + $b;
    }
? >

PHPUnit--skeleton Calculator
phpunit 3.2.10 by Sebastian Bergmann.

Wrote test class skeleton for Calculator to calculatortest.php.

Simple. Simple, but it doesn't really make sense, because there's no test data, how to add data, oh oh oh, the play is coming

<?php
class Calculator
{
    /**
     * @assert (0, 0) = = 0
     * @assert (0, 1) = = 1
     * @assert (1, 0) = = 1
     * @assert (1, 1) = = 2/Public
    function Add ($a, $b)
    {return
        $a + $b;
    }
}
?>

Each method in the original class is instrumented for @assert annotations. These are translated into Test code, like this
/**
* Generated from @assert (0, 0) = = 0.
*/
Public Function Testadd () {
$o = new Calculator;
$this->assertequals (0, $o->add (0, 0));
}
The following is the output of the test case class that runs the build.
