Perhaps you need to create a stub to pass in as the constructor argument. Then you can break that chain of mock objects.

You can use <code>getMockBuilder</code> instead of just <code>getMock</code>:

<pre><code>$mock = $this-&gt;getMockBuilder('class_name')
 -&gt;disableOriginalConstructor()
 -&gt;getMock();
</code></pre>

See the section on <a href="http://phpunit.de/manual/current/en/test-doubles.html">"Test Doubles"</a> in <a href="http://phpunit.de/manual">PHPUnit's documentation</a> for details.

Although you can do this, it's much better to not need to. You can refactor your code so instead of a concrete class (with a constructor) needing to be injected, you only depend upon an interface. This means you can mock or stub the interface without having to tell PHPUnit to modify the constructor behaviour.

blocks|key|1693131|text|作为补充，我想将expects()调用附加到我的模拟对象，然后调用构造函数。在PHPUnit+3.7.14中，调用disableOriginalConstructor()时返回的对象实际上是一个对象。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1693132|//+Use+a+trick+to+create+a+new+object+of+a+class

As an addendum, I wanted to attach <code>expects()</code> calls to my mocked object and then call the constructor. In PHPUnit 3.7.14, the object that is returned when you call <code>disableOriginalConstructor()</code> is literally an object. 

<pre><code>// Use a trick to create a new object of a class
// without invoking its constructor.
$object = unserialize(
sprintf('O:%d:"%s":0:{}', strlen($className), $className)
</code></pre>

Unfortunately, in PHP 5.4 there is a new option which they aren't using:

<a href="http://php.net/manual/en/reflectionclass.newinstancewithoutconstructor.php" rel="nofollow">ReflectionClass::newInstanceWithoutConstructor</a>

Since this wasn't available, I had to manually reflect the class and then invoke the constructor.

<pre><code>$mock = $this-&gt;getMockBuilder('class_name')
 -&gt;disableOriginalConstructor()
 -&gt;getMock();

$mock-&gt;expect($this-&gt;once())
 -&gt;method('functionCallFromConstructor')
 -&gt;with($this-&gt;equalTo('someValue'));

$reflectedClass = new ReflectionClass('class_name');
$constructor = $reflectedClass-&gt;getConstructor();
$constructor-&gt;invoke($mock);
</code></pre>

Note, if <code>functionCallFromConstruct</code> is <code>protected</code>, you specifically have to use <code>setMethods()</code> so that the protected method is mocked. Example:

<pre><code> $mock-&gt;setMethods(array('functionCallFromConstructor'));
</code></pre>

<code>setMethods()</code> must be called before the <code>expect()</code> call. Personally, I chain this after <code>disableOriginalConstructor()</code> but before <code>getMock()</code>.

blocks|key|1477930|text|或者，您可以向getMock添加一个参数，以防止调用默认构造函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1477931|$mock+=+$this->getMock(class_name,+methods+=+array(),+args+=+array(),+

Alternatively you could add a parameter to <a href="https://damienflament.github.io/phpunit-mock-objects-api-docs/4.0.0/PHPUnit_Framework_MockObject_Generator.html#method_getMock" rel="nofollow noreferrer">getMock</a> to prevent the calling of the default constructor.

<pre><code>$mock = $this-&gt;getMock(class_name, methods = array(), args = array(), 
 mockClassName = '', callOriginalConstructor = FALSE);
</code></pre>

Still, I think the answer of dave1010 looks nicer, this is just for the sake of completeness.

What is the way to avoid phpunit having to call the constructor for a mock object? Otherwise I would need a mock object as constructor argument, another one for that etc. The api seems to be like this:

<pre><code>getMock($className, $methods = array(), array $arguments = array(),
 $mockClassName = '', $callOriginalConstructor = TRUE,
 $callOriginalClone = TRUE, $callAutoload = TRUE)
</code></pre>

I don't get it to work. It still complains about the constructor argument, even with <code>$callOriginalConstructor</code> set to false.

I only have one object in the constructor and it is a dependency injection. So I don't think I have a design problem there.

phpunit avoid constructor arguments for mock

有什么方法可以避免phpunit调用mock对象的构造函数？否则，我将需要一个模拟对象作为构造函数参数，另一个对象作为构造函数参数，等等。api看起来是这样的：getMock($className, $methods = array(), array $arguments = array(),        $mock...
