Powermockito静态方法调用

Question

我有一个class A，它具有静态方法testA(String auditUser, Timestamp timestamp)，如果class B为auditUser，则该方法调用admin的静态方法。我正在尝试为A类编写测试。如何验证B的静态方法是否被调用？

class A {
  public static testA(String auditUser, Timestamp timestamp) {
    if ("admin".equalsIgnoreCase(auditUser) {
      B.testB(timestamp);
    }
  }
}

class B {
  public static testB(Timestamp timestamp) {
  //...some logic...//
  }
}

我为您的静态方法添加了void以进行编译。

@SpringBootTest
@RunWith(PowerMockTestRunner.class)
@PrepareForTest(value = B.class)
public class TestClass {

    @Test
    public void testBAdmin() {
        String auditUser = "admin";
        Timestamp timestamp = new Timestamp(1577447182l);

        PowerMockito.mockStatic(B.class);
        //You can mock method here, if you need return value like this
        //when(B.testB(timestamp)).thenReturn("some_value");

        A.testA(auditUser, timestamp);

        PowerMockito.verifyStatic(B.class);
        B.testB(timestamp);
    }
    @Test
    public void testBNotAdmin() {
        String auditUser = "not_admin";
        Timestamp timestamp = new Timestamp(1577447182l);

        PowerMockito.mockStatic(B.class);
        //You can mock method here, if you need return value like this
        //when(B.testB(timestamp)).thenReturn("some_value");

        A.testA(auditUser, timestamp);

        PowerMockito.verifyZeroInteractions(B.class);
    }
}
class A {
    public static void testA(String auditUser, Timestamp timestamp) {
        if ("admin".equalsIgnoreCase(auditUser)) {
            B.testB(timestamp);
        }
    }
}

class B {
    public static void testB(Timestamp timestamp) {
//...some logic...//
    }
}

并且不要忘记Maven依赖项
