[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 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 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 ?>

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.

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 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 ?>

phpunit ExpectedErrorTest
PHPUnit 3.4.2 by Sebastian Bergmann.

Time: 0 seconds

OK (1 test, 1 assertion)
