Android studio Junit-需要Mockito，但未调用

我正在尝试使用junit测试我的类MoviesRepository：

@Test
fun getMovieDetail() {
    doAnswer { invocation ->
        (invocation.arguments[0] as RemoteDataSource.LoadMovieDetailCallback).onMovieDetailReceived(
            moviesResponses[0]
        )
        null
    }.`when`(remote).getMovieDetail(eq(movieId), any())

    val moviesEntities = LiveDataTestUtil.getValue(moviesRepository.getMovieDetail(movieId))

    verify(remote).getMovieDetail(eq(movieId), any())
    assertNotNull(moviesEntities)
    assertNotNull(moviesEntities.id)

    assertEquals(moviesResponses[0].id, moviesEntities.id)
}

但是我想要但被调用了。也就是说，我的类remoteDataSource和FakeMoviesRepository中的remoteDataSource.getMoviesDetail（）出现了问题

override fun getMovieDetail(movieId: String): LiveData<Movies> {
    val movieResult = MutableLiveData<Movies>()
    CoroutineScope(Dispatchers.IO).launch {
        remoteDataSource.getMovieDetail(movieId, object : RemoteDataSource.LoadMovieDetailCallback{
            override fun onMovieDetailReceived(movieResponse: Movies) {
                val movie = Movies(
                    id = movieResponse.id,
                    title = movieResponse.title,
                    overview = movieResponse.overview,
                    poster = movieResponse.poster,
                    vote = movieResponse.vote,
                    release = movieResponse.release
                )

                movieResult.postValue(movie)
            }
        })
    }

    return movieResult
}

这是我的类RemoteDataSource

fun getMovieDetail(movieId: String, callback: LoadMovieDetailCallback) {
    EspressoIdlingResource.increment()
    movieApiClient.getMovieDetail(movieId)
        .enqueue(object : Callback<Movies>{
            override fun onResponse(call: Call<Movies>, response: Response<Movies>) {
                if (response.isSuccessful)
                    response.body()?.let {
                        callback.onMovieDetailReceived(it)
                    }
            }

            override fun onFailure(call: Call<Movies>, t: Throwable) {
                Log.e("OnFailure DetailMovie", t.message.toString())
            }

        })

    EspressoIdlingResource.decrement()
}

fun getMovieDetail（movieId:String，callback:LoadMovieDetailCallback）{
espressoidingresource.increment（）
movieApiClient.getMovieDetail（movieId）
.enqueue（对象：回调{
覆盖fun onResponse（调用：调用，响应：响应）{
if（response.issucessful）
response.body（）？.let{
callback.onMovieDetailReceived（it）
}
}
覆盖失效时的乐趣（调用：调用，t:可丢弃）{
Log.e（“OnFailure DetailMovie”，t.message.toString（））
}
})
浓缩咖啡资源减量（）
}

这是我班的假货记录

override fun getMovieDetail(movieId: String): LiveData<Movies> {
    val movieResult = MutableLiveData<Movies>()
    CoroutineScope(Dispatchers.IO).launch {
        remoteDataSource.getMovieDetail(movieId, object : RemoteDataSource.LoadMovieDetailCallback{
            override fun onMovieDetailReceived(movieResponse: Movies) {
                val movie = Movies(
                    id = movieResponse.id,
                    title = movieResponse.title,
                    overview = movieResponse.overview,
                    poster = movieResponse.poster,
                    vote = movieResponse.vote,
                    release = movieResponse.release
                )

                movieResult.postValue(movie)
            }
        })
    }

    return movieResult
}

override-fun-getMovieDetail（movieId:String）：LiveData{
val movieResult=MutableLiveData（）
协同路由示波器（Dispatchers.IO）。启动{
remoteDataSource.getMovieDetail（movieId，对象：remoteDataSource.LoadMovieDetailCallback{
覆盖MovieDetailReceived上的乐趣（MovierResponse:Movies）{
电影(
id=movieResponse.id，
title=movieResponse.title，
概述=movieResponse.overview，
poster=movieResponse.poster，
投票，
release=movieResponse.release
)
movieResult.postValue（电影）
}
})
}
返回电影结果
}

有人能提出一些解决办法吗
