Mockito模拟SecurityManager抛出异常 [英] Mockito mock of SecurityManager throwing an exception
问题描述
我正在尝试模拟 SecurityManager
类。当我运行以下代码时,Mockito抛出异常:
I'm trying to mock the SecurityManager
class. When I run the following code, Mockito throws an exception:
@After
public void tearDown()
{
SecurityManager securityManagerMock = mock(SecurityManager.class);
System.setSecurityManager(securityManagerMock);
}
堆栈跟踪是无限重复的以下行:
The stack trace is the following lines repeated indefinitely:

我在这里做错了什么?
推荐答案
PS!您还可以模拟对getSecurityManager()方法的静态方法调用。
PS! You could also mock static method call to getSecurityManager() method.
模拟静态方法
请参阅 http://code.google.com/p/powermock/wiki/MockitoUsage
在班级添加@PrepareForTest。
Add @PrepareForTest at class level.
@PrepareForTest(System.class); // System.class contains static methods
调用PowerMockito.mockStatic()来模拟静态类(使用PowerMockito.mockStaticPartial(类,方法)来模拟特定方法):
Call PowerMockito.mockStatic() to mock a static class (use PowerMockito.mockStaticPartial(class, method) to mock a specific method):
PowerMockito.mockStatic(System.class);
只需使用Mockito.when()来设定您的期望:
Just use Mockito.when() to setup your expectation:
Mockito.when(System.getSecurityManager()).thenReturn(securityManagerMock);
