我是PHPUnit测试的新手，所以稍后我会对它提出很多疑问，但首先，一步一步走。
我试图从netbeans网站关注以下this tutorial。
不幸的是，文档有点过时了，我想不太精确。
我在Win7 Ultimate 64bit上使用Netbeans 8.0.2
所以，我创建了一个新项目，并在其下Calculator.php并复制了教程中的代码。
然后我右键点击它，比如，工具 - ＆gt;创建测试。在我的test目录中，骨架生成器创建CalculatorTest。
文档忘记提及创建boostrap以包含Calculator.php进行测试，但不要卡在上面，我做了。
现在，我右键点击Calculator.php并说Test。结果不是我所期望的。
测试结果窗口显示：No test executed，而右侧显示：
Perhaps error occurred, verify in Output window.
很抱歉这一大堆代码，我只想确定，你看到我做了什么，所以这里是输出窗口的内容（见下文）。
我做错了什么，我该如何解决这个问题？
