Question

我正在尝试在我们的Android应用上设置facebook的screenshot-tests-for-android（v0.8.0），但出现以下错误：

java.lang.RuntimeException: Failed to create the directory /sdcard/screenshots/com.schibsted.peil.android.dev.test/screenshots-default for screenshots. Is your sdcard directory read-only?
at com.facebook.testing.screenshot.internal.ScreenshotDirectories.getSdcardDir(ScreenshotDirectories.java:121)
at com.facebook.testing.screenshot.internal.ScreenshotDirectories.get(ScreenshotDirectories.java:53)
at com.facebook.testing.screenshot.internal.AlbumImpl.<init>(AlbumImpl.java:44)
at com.facebook.testing.screenshot.internal.AlbumImpl.create(AlbumImpl.java:49)
at com.facebook.testing.screenshot.internal.ScreenshotImpl.create(ScreenshotImpl.java:66)
at com.facebook.testing.screenshot.internal.ScreenshotImpl.getInstance(ScreenshotImpl.java:84)
at com.facebook.testing.screenshot.Screenshot.snap(Screenshot.java:38)
at com.sample.myapp.ThirteenCardScreenshotTest.testScreenshot(ThirteenCardScreenshotTest.kt:24)

在我的应用AndroidManifest.xml上，我明确设置了库所需的WRITE_EXTERNAL_STORAGE权限，关于运行检测测试的权限似乎发生了变化，但似乎在检测测试中不可用？还是其他？

有人有使用该库的经验吗？有什么建议吗？

我的测试如下：

package com.sample.myapp

import android.widget.LinearLayout
import androidx.test.InstrumentationRegistry
import com.facebook.testing.screenshot.Screenshot
import com.facebook.testing.screenshot.ViewHelpers
import com.sample.myapp.feed.FooterStoryViewHolder
import org.junit.Test

class ThirteenCardScreenshotTest {
    @Test
    fun testScreenshot() {
        val context = InstrumentationRegistry.getInstrumentation().targetContext

        val view = LinearLayout(context)
        val viewHolder = FooterStoryViewHolder(view)
        view.addView(viewHolder.itemView)

        ViewHelpers.setupView(view)
            .setExactWidthDp(360)
            .setExactHeightDp(740)
            .layout()

        Screenshot.snap(view)
            .record()
    }
}

如果您具有该应用程序的调试环境，请将其添加到其清单中：

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

否则，您将不得不将其放入默认应用清单中
