java - Mockito验证方法调用的顺序/顺序

有没有一种方法可以验证在Mockito中是否在methodOne之前调用了methodTwo？

public class ServiceClassA {
    public void methodOne(){}
 }

public class ServiceClassB {
    public void methodTwo(){}
 }

public class TestClass {
    public void method(){
        ServiceClassA serviceA = new ServiceClassA();
        ServiceClassB serviceB = new ServiceClassB();
        serviceA.methodOne();
        serviceB.methodTwo();
    }
}

最佳答案

InOrder 可以帮助您做到这一点。

ServiceClassA firstMock = mock(ServiceClassA.class);
ServiceClassB secondMock = mock(ServiceClassB.class);

Mockito.doNothing().when(firstMock).methodOne();
Mockito.doNothing().when(secondMock).methodTwo();

//create inOrder object passing any mocks that need to be verified in order
InOrder inOrder = inOrder(firstMock, secondMock);

//following will make sure that firstMock was called before secondMock
inOrder.verify(firstMock).methodOne();
inOrder.verify(secondMock).methodTwo();
