Espresso UI testing doesn't recognize onView()
提问by somerandomusername
I have spent all day setting up Junit4 instrumentation tests with Espresso, but just can't seem to get that final step. No matter what I do it won't recognize the onView()method. I have tried multiple SDK/support-lib versions and so far nothing. I have gone through all the google setup guides and many stackoverflow posts, turning here as my last hope.
我花了一整天的时间用 Espresso 设置 Junit4 仪器测试，但似乎无法完成最后一步。无论我做什么，它都无法识别该onView()方法。我已经尝试了多个 SDK/support-lib 版本，但到目前为止一无所获。我已经浏览了所有 google 设置指南和许多 stackoverflow 帖子，将这里作为我最后的希望。

PS. I use roboguice could that be the issue?
附注。我使用 roboguice 这可能是问题吗？

You should either use a static import:
您应该使用静态导入：
import static android.support.test.espresso.Espresso.onView;
or
或者
import android.support.test.espresso.Espresso;
and call it in the following way
并按以下方式调用它
Espresso.onView()

To extend what Egor has suggested, in Android Studio, once you get red text at onView(), simply press alt+enterwhen the red bulb popped up. Then choose static import.
为了扩展 Egor 的建议，在 Android Studio 中，一旦您在 处看到红色文本onView()，只需在红色灯泡弹出时按alt+enter。然后选择静态导入。
回答by Pedro Gonzalez
Keep writing. Android Studio will suggest the needed Espresso imports, from the 'inside out'. For example: onView(withId()) First will detect withId(), then onView()
继续写。Android Studio 会从“由内而外”建议所需的 Espresso 导入。例如：onView(withId()) 首先会检测withId()，然后onView()

For AndroidX use this
对于 AndroidX 使用这个
import androidx.test.espresso.Espresso.onView
