Question

团队成员

class TeamImpls(val teamView: TeamView) : TeamPresenter {

    override fun loadTeamDetail(team_id: String) {
        val call = RetrofitConfig().getApi().getTeam(team_id)
        call.enqueue(object : Callback {
            override fun onResponse(call: Call, response: Response) {
                if (response.isSuccessful()) {
                    val res = response.body()
                    res?.let { teamView.onSuccess(it) }
                }
            }

            override fun onFailure(call: Call, t: Throwable) {
                Log.e("PrevMatchFragment", t.toString())
            }
        })
    }
}

团队模式

data class TeamModel(
        val teams: ArrayList
)

data class TeamModeLResult(
        val idTeam: String,
        val strTeam: String,
        val strAlternate: String,
        val strSport: String,
        val strStadium: String,
        val strTeamBadge: String
)

而且

class TeamImplsTest {

    @Mock
    private lateinit var teamView: TeamView

    @Mock
    private lateinit var teamPresenter: TeamPresenter

    @Before
    fun setUp() {
        MockitoAnnotations.initMocks(this)

        teamPresenter = TeamImpls(teamView)
    }

    @Test
    fun loadTeamDetail() {
        val teams = TeamModel(arrayListOf())

        val teamId = "133613"

        teamPresenter.loadTeamDetail(teamId)

        Mockito.verify(teamView).onSuccess(teams)
    }
}

我出错了

Wanted but not invoked:
teamView.onSuccess(TeamModel(teams=[]));
-> at com.fathurradhy.matchschedule.domain.presenter.TeamImplsTest.loadTeamDetail(TeamImplsTest.kt:34)
Actually, there were zero interactions with this mock.

Answer 1

因为loadTeamDetail创建了自己的API实例，所以您不是在嘲笑API调用。

为了使您能够测试API调用行为，您可以通过构造函数提供API实例，例如。

class TeamImpls(private val api: API, private val teamView: TeamView) : TeamPresenter {

    override fun loadTeamDetail(team_id: String) {
        val call = api.getTeam(team_id)

这将允许您模拟api行为，并在调用失败/成功时验证演示者调用了正确的方法，例如。

class TeamImplsTest {

    @Mock
    private lateinit var teamView: TeamView

    @Mock
    private lateinit var api: API

    @Mock
    private lateinit var teamPresenter: TeamPresenter

    @Before
    fun setUp() {
        MockitoAnnotations.initMocks(this)

        teamPresenter = TeamImpls(api, teamView)
    }

    @Test
    fun loadTeamDetail() {
        val teams = TeamModel(arrayListOf())

        val teamId = "133613"

        // Use retrofit-mock to create your mockResponse.
        // See: https://github.com/square/retrofit/tree/master/retrofit-mock
        Mockito.`when`(api.getTeam(teamId)).thenReturn(Calls.response(teams)

        teamPresenter.loadTeamDetail(teamId)

        Mockito.verify(teamView).onSuccess(teams)
    }
}
