无法模拟 TextMessage
unable to mock TextMessage
有人可以帮助我如何模拟这一行,我试过并得到空指针异常
mockTextMessage = mock(TextMessage.class);
when(mockTextMessage.getText()).thenReturn(any(String.class));
public void onMessage(Message message) {
String text = ((TextMessage)message).getText();
}
您应该在 thenReturn()
方法中传递实际对象。
见下面thenReturn(T value)
的定义
Sets a return value to be returned when the method is called.
"When the x method is called then return y".
例子
when(mock.x()).thenReturn(y);
when(mock.someMethod()).thenReturn(10);
在您的情况下,传递您希望在 mockTextMessage 上调用 getText() 方法时返回的实际字符串值。
when(mockTextMessage.getText()).thenReturn("expected value");
