Sounds like you need to remove the dependency of <code>time()</code> from your date manipulation class

blocks|key|3223859|text|我的猜测是，您正在为依赖项而苦苦挣扎。看起来您在类中使用了time()函数，而在进行单元测试时，您希望确保控制为您提供时间的方法/类的输出。我会说，创建一个为您提供时间的Time类，并将其模拟到您的单元测试中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3223860|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

My guess is you are struggling with your dependencies. It looks like you are using the time() function inside your class while with unit testing you want to make sure you control the output of the methods/classes that provide the time for you. I'd say create a Time class that provides you with the time and mock it into your unit tests.

blocks|key|288651|text|我最近提出了一个解决方案，如果您使用的是PHP5.3名称空间，这个解决方案会很棒。您可以在当前名称空间内实现一个新的time()函数，并创建一个共享资源，您可以在其中设置测试中的返回值。然后，任何对time()的非限定调用都将使用您的新函数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|288652|为了进一步阅读，我在我的blog中详细描述了它|offset|length|288653|entityMap|0|LINK|mutability|MUTABLE|url|https://www.schmengler-se.de/en/2011/03/php-mocking-built-in-functions-like-time-in-unit-tests/^0|0|C|4|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I recently came up with a solution that is great if you are using PHP 5.3 namespaces. You can implement a new time() function inside your current namespace and create a shared resource where you set the return value in your tests. Then any unqualified call to time() will use your new function.

For further reading I described it in detail in my <a href="https://www.schmengler-se.de/en/2011/03/php-mocking-built-in-functions-like-time-in-unit-tests/" rel="nofollow noreferrer">blog</a>

blocks|key|3223929|text|您可以考虑基于接口的继承模型：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3223930|interface+iClock
{
++++public+function+getTime();

}

class+SystemClock+implements+iClock
{
++++public+function+getTime()
++++{
++++++++return+time();
++++}
}

class+FakeClock+implements+iClock
{
++++private+$time;

++++function+__construct($time)
++++{
++++++++$this->time+=+$time;
++++}

++++public+function+getTime()
++++{
++++++++return+$this->time;
++++}

++++//+you+could+have+more+functions+to+advance+the+time,+etc.
}|code-block|syntax|javascript|3223931|需要使用当前时间的您自己的类将采用iClock接口类型的构造函数参数。|offset|length|style|CODE|3223932|class+YourOwnClass
{
++++private+$clock;

++++function+__construct(iClock+$clock)
++++{
++++++++$this->clock+=+$clock;
++++}

++++function+someFunction()
++++{
++++++++$now+=+$this->clock->getTime();

++++++++//+whatever
++++++++return+$now;
++++}
}|3223933|然后，您只需注入所需的时钟类型，这取决于您是否处于单元测试中：|3223934|$realWorldInstance+=+new+YourOwnClass(new+SystemClock());+++
echo+$realWorldInstance->someFunction();|3223935|$unitTestInstance+=+new+YourOwnClass(new+FakeClock(1234));
echo+$unitTestInstance->someFunction();|3223936|顺便说一句，我也经常在.NET中使用这种模式。它还内置于Noda+Time提供的IClock接口中。我看不出为什么这个模式不能在PHP中工作。您可以选择返回一个DateTime，而不仅仅是整数时间戳，但以上是使用该模式所需的最小值。|3223937|entityMap|0|LINK|mutability|MUTABLE|url|http://nodatime.org/^0|0|0|H|6|0|0|0|0|0|14|6|28|8|S|9|0|0^^$0|@$1|2|3|4|5|6|7|14|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|15|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|16|8|@$I|17|J|18|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|19|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|1A|8|@]|9|@]|A|$]]|$1|Q|3|R|5|D|7|1B|8|@]|9|@]|A|$E|F]]|$1|S|3|T|5|D|7|1C|8|@]|9|@]|A|$E|F]]|$1|U|3|V|5|6|7|1D|8|@$I|1E|J|1F|K|L]|$I|1G|J|1H|K|L]]|9|@$I|1I|J|1J|1|1K]]|A|$]]|$1|W|3|-4|5|6|7|1L|8|@]|9|@]|A|$]]]|X|$Y|$5|Z|10|11|A|$12|13]]]]

You might consider an interface-based inheritance model:

<pre><code>interface iClock
{
 public function getTime();

}

class SystemClock implements iClock
{
 public function getTime()
 {
 return time();
 }
}

class FakeClock implements iClock
{
 private $time;

 function __construct($time)
 {
 $this-&gt;time = $time;
 }

 public function getTime()
 {
 return $this-&gt;time;
 }

 // you could have more functions to advance the time, etc.
}
</code></pre>

Your own classes that need to work with the current time would take a constructor parameter of the <code>iClock</code> interface type.

<pre><code>class YourOwnClass
{
 private $clock;

 function __construct(iClock $clock)
 {
 $this-&gt;clock = $clock;
 }

 function someFunction()
 {
 $now = $this-&gt;clock-&gt;getTime();

 // whatever
 return $now;
 }
}
</code></pre>

Then you would simply inject the type of clock you wanted, depending on whether you were in a unit test or not:

<pre><code>$realWorldInstance = new YourOwnClass(new SystemClock()); 
echo $realWorldInstance-&gt;someFunction();
</code></pre>



<pre><code>$unitTestInstance = new YourOwnClass(new FakeClock(1234));
echo $unitTestInstance-&gt;someFunction();
</code></pre>

BTW - I use this pattern often in .NET as well. It's also built into the <code>IClock</code> interface provided by <a href="http://nodatime.org" rel="nofollow">Noda Time</a>. I see no reason why this pattern wouldn't work in PHP. You might choose to return a <code>DateTime</code> instead of just the integer timestamp, but the above is the minimal needed to use the pattern.

How can I change the current time (i.e. the output of <code>time()</code>) in PHP for unit-testing date-manipulation-class?
