Robolectric测试-并发线程问题

编程问答 2022-06-06

问题描述

我想用Espresso打开抽屉布局并测试它是否打开。但简单的代码如下：

@RunWith(AndroidJUnit4::class)
@LooperMode(LooperMode.Mode.PAUSED)
class MainActivityTest {

    @Rule
    @JvmField
    val rule = InstantTaskExecutorRule()

    @Rule
    @JvmField
    val activity = ActivityScenarioRule(MainActivity::class.java)

    @Test
    fun isDrawerOpening(){
        onView(withId(R.id.drawerLayoutMain))
            .check(matches(isDisplayed()))
            .check(matches(isClosed()))
            .perform(open())

        Shadows.shadowOf(Looper.getMainLooper()).idle()

        onView(withId(R.id.drawerLayoutMain)).check(matches(isOpen()))
    }

}

不想工作。它在check(matches(isOpen()))上失败。这是一条日志：

如何用Espresso打开它？我使用Robolectric和Navigation。我想测试我的主要活动并单击抽屉中的导航按钮。当我使用该应用程序时，它可以工作。但是使用Espresso无法达到相同的效果。

我的依赖项：

testImplementation 'androidx.test.espresso:espresso-core:3.3.0'
testImplementation 'androidx.test.espresso:espresso-contrib:3.3.0'
testImplementation 'androidx.test.espresso:espresso-intents:3.3.0'
testImplementation 'org.robolectric:robolectric:4.3'

我的布局：

活动：

class MainActivity : AppCompatActivity() {

    @Inject
    lateinit var moviesFragmentsFactory: MoviesFragmentsFactory
    private val navHostFragment by lazy {
        supportFragmentManager.findFragmentById(R.id.navHostFragmentView) as NavHostFragment }
    private val navController by lazy { navHostFragment.navController }
    private val appBarConfiguration by lazy {
        AppBarConfiguration(setOf(R.id.destinationDb,R.id.destinationApi),drawerLayoutMain) }

    override fun onCreate(savedInstanceState: Bundle?) {
        AndroidInjection.inject(this)
        supportFragmentManager.fragmentFactory = moviesFragmentsFactory
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        navDrawer.setupWithNavController(navController)
        toolbarMovies.setupWithNavController(navController,appBarConfiguration)
        toolbarMovies.setNavigationOnClickListener(openCloseDrawerNavClick)
    }

    private val openCloseDrawerNavClick = View.OnClickListener {
        if (drawerLayoutMain.isDrawerOpen(GravityCompat.START)){
            drawerLayoutMain.closeDrawer(GravityCompat.START)
        } else {
            navController.navigateUp(appBarConfiguration)
        }
    }

}
