我不确定是我做错了什么,还是 PHPUnit 和模拟对象的错误。基本上我想测试是否 $Model->doSomething()
在 $Model->start()
时调用被触发。
我在 VirtualBox 中使用 Ubuntu,并通过 pear 安装了 phpunit 1.1.1。
完整代码如下。任何帮助将不胜感激,这让我发疯。
<?php
require_once 'PHPUnit/Autoload.php';
class Model
{
function doSomething( ) {
echo 'Hello World';
}
function doNothing( ) { }
function start( ) {
$this->doNothing();
$this->doSomething();
}
}
class ModelTest extends PHPUnit_Framework_TestCase
{
function testDoSomething( )
{
$Model = $this->getMock('Model');
$Model->expects($this->once())->method('start'); # This works
$Model->expects($this->once())->method('doSomething'); # This does not work
$Model->start();
}
}
?>
PHPUnit的输出:
There was 1 failure:
1) ModelTest::testDoSomething
Expectation failed for method name is equal to <string:doSomething> when invoked 1 time(s).
Method was expected to be called 1 times, actually called 0 times.
FAILURES!
Tests: 1, Assertions: 1, Failures: 1.
最佳答案
正如您所发现的,您需要告诉 PHPUnit 要模拟哪些方法。此外,我会避免为您直接从测试中调用的方法创建期望。我会这样写上面的测试:
function testDoSomething( )
{
$Model = $this->getMock('Model', array('doSomething');
$Model->expects($this->once())->method('doSomething');
$Model->start();
}
关于PHPUnit 和 Mock 对象不起作用,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/12131454/
