如何将 Espresso Idling Resource 与 Kakao 一起使用？

Question

我使用以下空闲资源实现来等待元素出现在屏幕上，然后再执行检查。

private class ViewPropertyChangeCallback(private val matcher: Matcher<View>, private val view: View) : IdlingResource, ViewTreeObserver.OnDrawListener {

    private lateinit var callback: IdlingResource.ResourceCallback
    private var matched = false

    override fun getName() = "View property change callback"

    override fun isIdleNow() = matched

    override fun registerIdleTransitionCallback(callback: IdlingResource.ResourceCallback) {
        this.callback = callback
    }

    override fun onDraw() {
        matched = matcher.matches(view)
        callback.onTransitionToIdle()
    }
}

fun waitUntil(matcher: Matcher<View>): ViewAction = object : ViewAction {

    override fun getConstraints(): Matcher<View> {
        return Matchers.any(View::class.java)
    }

    override fun getDescription(): String {
        return StringDescription().let {
            matcher.describeTo(it)
            "wait until: $it"
        }
    }

    override fun perform(uiController: UiController, view: View) {
        if (!matcher.matches(view)) {
            ViewPropertyChangeCallback(matcher, view).run {
                try {
                    IdlingRegistry.getInstance().register(this)
                    view.viewTreeObserver.addOnDrawListener(this)
                    uiController.loopMainThreadUntilIdle()
                } finally {
                    view.viewTreeObserver.removeOnDrawListener(this)
                    IdlingRegistry.getInstance().unregister(this)
                }
            }
        }
    }
}
fun waitForElement(matcher: Matcher<View>) {
    onView(isRoot())
        .perform(waitUntil(hasDescendant(matcher)))
}

fun waitElement(element: Matcher<View>, matching: Matcher<View> = isDisplayed()) {
    waitForElement(Matchers.allOf(element, matching))
}

我可以这样使用它：

fun waitForButton() {
    waitElement(withId(R.id.buttonId))
}

我想要实现的是使用空闲资源与

Kakao KBaseView<*>

喜欢：

private val buttonElement = KButton {withId(R.id.buttonId)}
fun waitForButton() {
    buttonElement.waitElement()
}

我刚刚开始在 Android 上进行自动化测试，因此我将不胜感激任何有关如何执行此操作的示例或技巧

由于Kakao没有内置的等待机制，我们可以使用空闲资源逻辑来扩展KBaseView。方法如下：

open class KBaseViewWithIdlingResource<T>(private val viewMatcher: Matcher<View>) : KBaseView<T>() {

    private var callback: IdlingResource.ResourceCallback? = null

    private fun registerIdlingResource() {
        val idlingResource = ViewPropertyChangeCallback(viewMatcher, view)
        IdlingRegistry.getInstance().register(idlingResource)
        idlingResource.registerIdleTransitionCallback {
            callback?.onTransitionToIdle()
            IdlingRegistry.getInstance().unregister(idlingResource)
        }
    }

    fun waitUntilDisplayed() {
        registerIdlingResource()
        Espresso.onView(withId(id)).perform(waitForView())
    }
}
