[PHP]PHPUnit入门之三

testing exceptions

 

@expectedException声明用来测试测试代码中指定异常是否被抛出

代码

 1 php
 2 require_once   ' PHPUnit/Framework.php ' ;
 3  
 4 class  ExceptionTest  extends  PHPUnit_Framework_TestCase
 5 {
 6      /* *
 7      * @expectedException InvalidArgumentException
 8       */
 9      public   function  testException()
10     {
11     }
12 }
13 ?>

phpunit ExceptionTest
PHPUnit 3.4.2 by Sebastian Bergmann.

F

Time: 0 seconds

There was 1 failure:

1) testException(ExceptionTest)
Expected exception InvalidArgumentException

FAILURES!
Tests: 1, Assertions: 1, Failures: 1.

另外，你也可以使用setExpectedException()来设置期望抛出的异常

代码

 1 php
 2 require_once   ' PHPUnit/Framework.php ' ;
 3  
 4 class  ExceptionTest  extends  PHPUnit_Framework_TestCase
 5 {
 6      public   function  testException()
 7     {
 8          $this -> setExpectedException( ' InvalidArgumentException ' );
 9     }
10 }
11 ?>

Expected exception InvalidArgumentException

FAILURES!

Testing PHP Errors
默认设置下，PHPUnit把执行中触发的error,warning,notice都转化成一个exception.

代码

 1 php
 2 class  ExpectedErrorTest  extends  PHPUnit_Framework_TestCase
 3 {
 4      /* *
 5      * @expectedException PHPUnit_Framework_Error
 6       */
 7      public   function  testFailingInclude()
 8     {
 9          include   ' not_existing_file.php ' ;
10     }
11 }
12 ?>
