[解決済み】Mockitoでメソッド呼び出しの順序・順番を検証する

質問

を確認する方法はありますか？ methodOne が呼び出される前に methodTwo をMockitoで使うのですか？

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();
    }
}

解決方法は？

InOrder は、そのための手助けをしてくれます。

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();
