Compose Android 测试惰性列未检测到所有子项
问题描述 投票：0回答：1
我在 Composable 中有一个 LazyColumn，我想检查 LazyColumn 中的每个项目是否存在。
这是我的可组合项： （注意：实际上在我的真实案例中，每个项目都有不同的组件，我只是为了简化问题而使其相似）
@Composable
fun HomeScreen(){
LazyColumn(){
item {
HomeBanner()
Text("Test1",Modifier.testTag("tag1"))
}
item {
HomeBanner()
Text("Test2",Modifier.testTag("tag2"))
}
item {
HomeBanner()
Text("Test3",Modifier.testTag("tag3"))
}
item {
HomeBanner()
Text("Test4",Modifier.testTag("tag4"))
}
item {
HomeBanner()
Text("Test5",Modifier.testTag("tag5"))
}
item {
HomeBanner()
Text("Test6",Modifier.testTag("tag6"))
}
}
}
这就是它的样子：
这是我的测试课：
@ExperimentalCoroutinesApi
@ExperimentalMaterialApi
@ExperimentalPagerApi
@HiltAndroidTest
@RunWith(AndroidJUnit4::class)
class HomeScreenTest {
@get:Rule(order = 0)
val hiltRule = HiltAndroidRule(this)
@ExperimentalMaterialApi
@get:Rule(order = 1)
val composeTestRule = createAndroidComposeRule<MainActivity>()
@Inject
lateinit var mainRepository: MainRepository
@Before
fun setup() {
hiltRule.inject()
}
@Test
fun property_list_is_displayed() = runTest {
composeTestRule.onRoot().printToLog("GALIH")
composeTestRule.onNodeWithTag("tag1").assertExists()
composeTestRule.onNodeWithTag("tag2").assertExists()
composeTestRule.onNodeWithTag("tag3").assertExists()
composeTestRule.onNodeWithTag("tag4").assertExists()
composeTestRule.onNodeWithTag("tag5").assertExists()
}
}
断言 Exist the
tag5java.lang.AssertionError: Failed: assertExists.
Reason: Expected exactly '1' node but could not find any node that satisfies: (TestTag = 'tag5')
我看日志的时候，显示view hierarchy中没有tag5
printToLog:

我有一个类似的问题，直到现在，我发现解决的唯一方法是使用
performTouchInput{ swipeUp() }在你的情况下，你可能需要为你的 lazycolumn 设置标签，并且在执行
swipeup() @Test
fun property_list_is_displayed() = runTest {
composeTestRule.onRoot().printToLog("GALIH")
composeTestRule.onNodeWithTag("tag1").assertExists()
composeTestRule.onNodeWithTag("tag2").assertExists()
composeTestRule.onNodeWithTag("tag3").assertExists()
composeTestRule.onNodeWithTag("tag4").assertExists()
composeTestRule.onNodeWithTag("lazycolumn")
.performTouchInput{ swipeUp() }
.onChildren()
.onLast()
.assertTextContains("Test5")
}
