如何使用特定視圖 Visible- Espresso 單擊 Recyclerview position

Question

我正在使用 Espresso 為我的應用編寫 UI 測試。 屏幕顯示一個Recyclerview ，其中包含狀態為OPEN或CLOSED的商店列表。 根據數據， openTextView或closedTextview默認顯示和隱藏。

以下是我的測試用例場景：

• 檢查屏幕是否可見
• 檢查 Recyclerview 是否可見
• 檢查 Recyclerview 是否至少有一家商店處於OPEN狀態
• 點擊第一個找到的OPEN店鋪
• 檢查詳細信息屏幕是否顯示

問題：

我試圖單擊第一個OPEN狀態項，但它拋出異常。

下面是代碼

@Test
fun openShopTest() {

    onView(withText(“Shops")).check(matches(isDisplayed()))

    onView(withId(R.id.rvShops)).check(matches(isDisplayed()))

    //There is at least one open shop visible

    onView(withId(R.id.rvShops))
        .perform(RecyclerViewActions.scrollToHolder(first(withOpenText())))

    //User clicks on open shop

    onView(allOf(withId(R.id.rvShops), isDisplayed()))
        .perform(actionOnItem<ListAdapter.ListViewHolder>(withChild(withText(“Open”)), click()))

    //Screen with details appear

    onView(withText("Details”)).check(matches(isDisplayed()))

}

fun withOpenText(): Matcher<RecyclerView.ViewHolder> {
    return object :
        BoundedMatcher<RecyclerView.ViewHolder, ListAdapter.ListViewHolder>(
            ListAdapter.ListViewHolder::class.java
        ) {

        override fun describeTo(description: Description) {
            description.appendText("No ViewHolder found with Open Status Visible")
        }

        override fun matchesSafely(item: ListAdapter.ListViewHolder): Boolean {
            val openTextView = item.itemView.findViewById(R.id.openTextView) as TextView
            return openTextView.isVisible
        }
    }
}

以下是例外情況：

我試過什么？

• 我有一個想法，也許openTextView或closedTextview並不總是可見的，所以這可能是導致問題的原因。 我也嘗試讓兩者始終可見。

• 我按照這個問題的答案中提到的步驟進行操作，但出現了同樣的問題。

需要什么？

• 單擊openTextView可見的 Recyclerview 行
• 獲取openTextView可見的行的openTextView ； 這樣我就可以使用atPosition function 並單擊該行。

有人可以幫我解決這個問題嗎？

任何幫助將不勝感激。

謝謝

這個想法是自定義 Espresso 的 View 操作。

object MyViewAction {
    fun clickChildViewWithIdAndText(id: Int, text: String): ViewAction {
        return object: ViewAction {
            override fun getConstraints(): Matcher<View> {
                return withText(text)
            }

            override fun getDescription(): String {
                return "Click on a child view with specified id and text"
            }

            override fun perform(uiController: UiController?, view: View) {
                val v: View = view.findViewById(id)
                v.performClick()
            }
        }
    }
}

onView(withId(R.id.rv_home)).perform(
      RecyclerViewActions.actionOnItemAtPosition<ListAdapter.ListViewHolder>(
          0,
          MyViewAction.clickChildViewWithIdAndText(R.id.tv_id, "OPEN")
      )
);

順便說一句，您可以使用一些構建在 Espresso 之上的強大測試庫，例如Barista或Kakao 。 它可以幫助您的測試代碼更具可讀性和優雅性。

例如，您可以僅用一行代碼斷言列表視圖中顯示在 position x 的項目和文本 y

import com.adevinta.android.barista.assertion.BaristaListAssertions.assertDisplayedAtPosition

assertDisplayedAtPosition(R.id.rv_list, x, R.id.tv_id, y)
