我正在试图模仿SecurityManager
类。当我运行以下代码时,Mockito会抛出异常:
@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:

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。
模拟静态方法 请参阅http://code.google.com/p/powermock/wiki/MockitoUsage
处的maunal在班级添加@PrepareForTest。
@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):
PowerMockito.mockStatic(System.class);
只需使用Mockito.when()来设定您的期望:
Mockito.when(System.getSecurityManager()).thenReturn(securityManagerMock);

更改SecurityManager时,应在测试后将其重置为原始SecurityManager。
您可以使用System Rules库进行测试。使用此规则设置和重置安全管理器只需两行代码。
@Rule
public ProvideSecurityManager provideSecurityManager
= new ProvideSecurityManager(yourSecurityManager);
在测试中使用yourSecurityManager,在测试之外使用原始安全管理器。
