PHPUnit没有捕获预期的异常 [英] PHPUnit doesn't catch expected exceptions

问题描述

我有一组测试，我想测试我的类在正确的时间抛出异常.在示例中，我的类使用__get()魔术方法，因此我需要测试是否在检索到无效属性时引发了异常:

I have a set of tests, and I want to test that my classes throw exceptions at the right time. In the example, my class uses the __get() magic method, so I need to test that an exception is thrown when an invalid property is retrieved:

function testExceptionThrownWhenGettingInvalidProperty() {
  $obj = new MyClass();
  $this->setExpectedException("Property qwerty does not exist");
  $qwerty = $obj->qwerty;
}

该类将引发应有的错误，但不会捕获异常，而不仅仅是获得通过！

The class throws an error as it should, but instead of just getting a pass, the exception isn't caught!

There was 1 error:

1) QueryTest::testExceptionThrownWhenGettingInvalidProperty
Exception: Property qwerty does not exist

我以前使用过SimpleTest，并且$this->expectException(new Exception("Property qwerty does not exist"));正常工作.我知道还有其他方法(@expectedException和try-catch)，但是这种方法应该可以工作，而且看起来更干净.有什么想法可以使我工作吗?

I was using SimpleTest before, and $this->expectException(new Exception("Property qwerty does not exist")); worked just fine. I know there are other methods (@expectedException and try-catch), but this one should work and it looks a lot cleaner. Any ideas how I can make this work?

推荐答案

它不是在查找异常中的文本，而是在寻找异常类的名称...

It's not looking for the text in the exception, it's looking for the name of the exception class... Docs

$this->setExpectedException('Exception');

当您使用 SPL异常时，这非常方便自定义异常类...

It's quite handy when you're using SPL Exceptions, or custom exception classes...
