【问题描述】：

我正在编写一个单元测试，我收到一条错误消息Following stubbings are unnecessary - Mockito。

org.mockito.exceptions.misusing.UnnecessaryStubbingException: Unnecessary stubbings detected in test class: ADataPresenterTest Clean & maintainable test code requires zero unnecessary code. Following stubbings are unnecessary

  @Test
    fun `return empty list of quality control checks when offline data quality checks are null`() {
        every(offlineDataStorage.offlineData.qualityChecks).thenReturn(null)// ERROR
        val listOfQCChecks = presenter.getQualityControlCheckData(QualityControlMilestone.FUELLING_ENDED)
        assertEquals(0, listOfQCChecks?.size)
    }

    @Test
    fun `return empty list of quality control checks when offline data quality checks are empty`() {
        val qualityControlChecks: ArrayList<QualityControlCheck> = ArrayList()
        every(offlineDataStorage.offlineData.qualityChecks).thenReturn(qualityControlChecks)//ERROR
        val listOfQCChecks = presenter.getQualityControlCheckData(QualityControlMilestone.FUELLING_ENDED)
        assertEquals(0, listOfQCChecks?.size)
    }

您能否建议如何解决此问题。

谢谢回复

【解决方案1】：

这意味着不需要存根

every(offlineDataStorage.offlineData.qualityChecks).thenReturn(qualityControlChecks)

删除它然后尝试。如果没有解决，请分享getQualityControlCheckData 以及与getQualityControlCheckData 相关的演示者中使用模拟的位置
