我的ViewModel
需求repository
和genre
通过构造函数。repository
由 Koin 提供,genre
字符串由活动提供
// Main app module
val MovieListModule: Module = applicationContext {
// provide repository
bean {
DummyMovieListRepository() as MovieListRepository
}
// provides ViewModel
viewModel { params: ParameterProvider ->
MovieListViewModel(respository = get(), genre = params["key.genre"])
}
}
//Module list for startKoin()
val appModules = listOf(MovieListModule)
//in activity
val viewModel = getViewModel<MovieListViewModel> {
mapOf("key.genre" to "Action / Drama")
}
// dry run test which fails
class KoinDryRunTest : KoinTest {
@Test
fun dependencyGraphDryRun() {
startKoin(list = appModules)
dryRun()
}
}
// some error log
org.koin.error.MissingParameterException: Parameter 'key.genre' is missing
at org.koin.dsl.context.ParameterHolder.get(ParameterHolder.kt:46)
org.koin.error.BeanInstanceCreationException: Can't create bean Factory[class=io.github.karadkar.popularmovies.MovieListViewModel, binds~(android.arch.lifecycle.ViewModel)] due to error :
org.koin.error.MissingParameterException: Parameter 'key.genre' is missing
这里 Koin (v 0.9.3) injection inactivity 按预期工作,但由于找不到参数,试运行测试失败key.genre
。检查完整的错误日志
有什么方法可以模拟/为key.genre
空运行测试提供价值?
