我正在尝试模拟 SecurityManager
类.当我运行以下代码时,Mockito 会抛出异常:
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);
}
堆栈跟踪是以下几行无限重复:
The stack trace is the following lines repeated indefinitely:

我在这里做错了什么?
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
在类级别添加@PrepareForTest.
Add @PrepareForTest at class level.
@PrepareForTest(System.class); // System.class contains static methods
调用 PowerMockito.mockStatic() 模拟静态类(使用 PowerMockito.mockStaticPartial(class, method) 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() 来设置您的期望:
Just use Mockito.when() to setup your expectation:
Mockito.when(System.getSecurityManager()).thenReturn(securityManagerMock);
