Android 浓缩咖啡测试：非法类访问：'androidx.test.core.app.ListFuture'尝试访问'androidx.concurrent.futures.DirectEx

Question

我有以下UI测试文件和我正在制作的应用程序的扩展文件：

package com.realtomjoney.pyxlmoose.activities.`2_canvas`
import androidx.test.espresso.Espresso.onView
import androidx.test.espresso.assertion.ViewAssertions.matches
import androidx.test.espresso.matcher.ViewMatchers.*
import androidx.test.ext.junit.rules.ActivityScenarioRule
import androidx.test.filters.LargeTest
import com.realtomjoney.pyxlmoose.R
import org.junit.Rule
import org.junit.Test
import org.junit.runner.RunWith
import androidx.test.internal.runner.junit4.AndroidJUnit4ClassRunner
import com.realtomjoney.pyxlmoose.AndroidTestUtilityFunctions
import com.realtomjoney.pyxlmoose.activities.canvas.CanvasActivity
@LargeTest
@RunWith(AndroidJUnit4ClassRunner::class)
class CanvasActivityTestsOnFindAndReplaceButtonTap {
@get:Rule
var activityTestRule = ActivityScenarioRule(CanvasActivity::class.java)
@Test fun uitest_doneButton_isNotDisplayed_after_findAndReplaceButton_isPressed() {
AndroidTestUtilityFunctions.goToFindAndReplaceFragment()
onView(withId(R.id.activityCanvas_doneButton)).check(matches(withEffectiveVisibility(Visibility.GONE)))
}
@Test fun uitest_colorPickerRecyclerView_isNotDisplayed_after_findAndReplaceButton_isPressed() {
AndroidTestUtilityFunctions.goToFindAndReplaceFragment()
onView(withId(R.id.activityCanvas_colorPickerRecyclerView)).check(matches(withEffectiveVisibility(Visibility.GONE)))
}
@Test fun uitest_titleTextView_isNotDisplayed_after_findAndReplaceButton_isPressed() {
AndroidTestUtilityFunctions.goToFindAndReplaceFragment()
onView(withId(R.id.activityCanvas_canvasTitleEditText)).check(matches(withEffectiveVisibility(Visibility.GONE)))
}
@Test fun uitest_colorSwapButton_isNotDisplayed_after_findAndReplaceButton_isPressed() {
AndroidTestUtilityFunctions.goToFindAndReplaceFragment()
onView(withId(R.id.activityCanvas_colorSwapButton)).check(matches(withEffectiveVisibility(Visibility.GONE)))
}
@Test fun uitest_colorPrimarySelected_isNotDisplayed_after_findAndReplaceButton_isPressed() {
AndroidTestUtilityFunctions.goToFindAndReplaceFragment()
onView(withId(R.id.activityCanvas_colorPrimaryView)).check(matches(withEffectiveVisibility(Visibility.GONE)))
}
@Test fun uitest_colorSecondarySelected_isNotDisplayed_after_findAndReplaceButton_isPressed() {
AndroidTestUtilityFunctions.goToFindAndReplaceFragment()
onView(withId(R.id.activityCanvas_colorSecondaryView)).check(matches(withEffectiveVisibility(Visibility.GONE)))
}
}

object AndroidTestUtilityFunctions {
private const val defaultProjectName = "Unnamed Project"
private const val defaultProjectSpanCount = 5
fun goToFindAndReplaceFragment() {
onView(withId(R.id.activityCanvas_canvasToolsScrollView)).perform(swipeLeft())
onView(withId(R.id.activityCanvas_findAndReplaceButton)).perform(click())
}
fun createNewProject(projectName: String = defaultProjectName, spanCount: Int = defaultProjectSpanCount) {
onView(withId(R.id.activityMain_newProjectButton)).perform(click())
onView(withId(R.id.fragmentNewCanvas_projectTitleTextInputEditText)).perform(replaceText(projectName))
onView(withId(R.id.fragmentNewCanvas_spanCountTextInputEditText)).perform(replaceText(spanCount.toString()))
onView(withId(R.id.fragmentNewCanvas_doneButton)).perform(click())
}
}

出于某种原因，当我运行UI测试时，我会得到以下令人讨厌的异常：

java.lang.IllegalAccessError: Illegal class access: 'androidx.test.core.app.ListFuture' attempting to access 'androidx.concurrent.futures.DirectExecutor' (declaration of 'androidx.test.core.app.ListFuture' appears in /data/app/~~xOjrSE9BCeINue7sOBFVJw==/com.realtomjoney.pyxlmoose.test-VqvV0FRJD_fIuyk2Jiuyyw==/base.apk)

我不知道为什么会发生这种情况，我已经尝试了几个星期来解决它，但没有成功——每当我尝试执行UI测试时，我仍然会遇到同样的异常。这是非常糟糕的，因为我实际上是在定期提交错误的代码！我真的需要解决这个问题。

我也遇到了同样的问题。我花了大量时间研究它，最终发现你的问题源于此：https://issuetracker.google.com/issues/204506297

从本质上讲，该版本的Espresso库试图使用另一个库中的枚举，而该库没有作用域访问权限。他们在这里解决了这个问题：https://github.com/android/android-test/pull/1174

不幸的是，在撰写本文时，3.5.0-alpha03是最新版本。因此，您可以等待alpha04/beta01，也可以降级回3.4.0，直到问题得到解决。
