使用此关键字在功能中使用此关键字的方法测试

Question

我想知道如何为涉及此关键字的方法编写单元测试用例。

dispenSeruleLogic包含这两种方法，其中一个使用此关键字调用另一个函数。所以我想知道如何为呼叫另一种内置方法的行创建一个存根。
我包括了代码，测试案例和错误。 班级名称：dispenSerulogic

Here is the method for which I want the test case to be written.

public boolean getAccessRuleSelect(String companyId) {
    boolean pinFlag = false;
    AllocationCode ac = new AllocationCode();
    ac.setCompanyId(companyId);
    Vector alCode = this.getAllocationCodeList(ac);
    AllocationAccessRule aar = new AllocationAccessRule();
    for (int i = 0; i < alCode.size(); i++) {
        aar.setAllocationCodeId(((AllocationCode) alCode.get(i))
                .getAllocationCodeId());

   //here this refers to DispenseRuleLogic
        if (this.getAllocationAccessRulePin(aar)) {
            pinFlag = true;
            break;
        }
    }
    return pinFlag;
}

What I have tried:

@Test
public void testGetAccessRuleSelect() throws Exception {
    // given
    boolean expected = true;
    Vector<AllocationCode> allocationCodeList = new Vector<>();
    AllocationCode allocationCodeMock = mock(AllocationCode.class);
    allocationCodeMock.setCompanyId(comId);
    allocationCodeList.add(allocationCodeMock);

    DispenseRuleLogic dispenseRuleLogic = new DispenseRuleLogic(dao);
    PowerMockito.whenNew(DispenseRuleLogic.class).withAnyArguments().thenReturn(dispenseRuleLogic);
    PowerMockito.when(DispenseRuleLogic.class, "getAllocationAccessRulePin", any(AllocationAccessRule.class)).thenReturn(true);
    //DispenseRuleLogic is the name of the class for which case is being written 
    
    // when
    boolean actual_result = dispenseRuleLogic.getAccessRuleSelect(comId);

    // then
    assertEquals(expected, actual_result);
}

Answer 1

如果无法在评论中提到的那样无法进行重构，那么您的spy在您的测试类中使用spy dispenserulelogic ：

@Mock
DispenseRuleLogic dispenseRuleLogic;

然后在您的测试方法中：

 dispenseRuleLogic =spy(DispenseRuleLogic.class);
 ..

when(dispenseRuleLogic.getAllocationCodeList(..)).thenReturn(allocationCodeList); //returning code list.
           when(dispenseRuleLogic.getAllocationAccessRulePin(..)).thenReturn(Booleam.TRUE); // retuning true when test calls this method.
            ..
            dispenseRuleLogic.getAccessRuleSelect(..) //test actual method
