使用JUnit测试具有布尔条件的无效方法

Question

我试图用Junit测试内部有布尔条件的void方法

/** Method to create request */
public void createRequest(String name) {

  if (verifyName(name)) {
    testRepo.getRequest(name); // Void method from test repo
    demoRepo.testMethod(name); // Another void method from demo repo
  }
}

/** Validate name */
private boolean verifyName(String name) {

 return "Test".equals(name);
}

在这种情况下，当verifyName（）使用JUnit返回true/false时，测试void方法的最佳方法是什么？？

预期测试场景：

1. verifyName（）返回true--

Answer 1

您可以简单地编写两个场景：

@Captor
private String ArgumentCaptor<String> nameCaptor;

@Test
public void testForValidName() {
    service.createRequest("Test");
    Mockito.verify(testRepo, Mockito.times(1)).getRequest(nameCaptor.capture());
    Mockito.verify(demoRepo, Mockito.times(1)).testMethod(nameCaptor.capture());
    List<String> capturedValues = nameCaptor.getValues();
    Assert.assertEquals("Test", capturedValues.get(0));
    Assert.assertEquals("Test", capturedValues.get(1));
}

@Test
public void testForInValidName() {
   service.createRequest("Test1");
   Mockito.verifyNoMoreInteractions(testRepo);
   Mockito.verifyNoMoreInteractions(demoRepo);
}

Answer 2

您可以根据条件验证是否调用了某个函数

试试这样吧

@Test
public void testValidName() {
    service.createRequest("Test");
    verify(testRepo, times(1)).getRequest();
    verify(demoRepo, times(1)). testMethod();
}
