将布局资源添加到androidTest [英] Adding layout resources to androidTest

问题描述

我想将布局xml文件添加到我的androidTest文件夹中，仅用于测试.

I would like to add layout xml files into my androidTest folder to be used only for testing.

我将res/layout文件夹添加到androidTest，并尝试向其中添加布局文件.但是它为xmlns:android="http://schemas.android.com/apk/res/android"

I added res/layout folder to androidTest and tried to add a layout file to it. But it gives error URI is not registered for xmlns:android="http://schemas.android.com/apk/res/android"

以某种方式，项目无法将其识别为有效的布局文件.

Somehow the project does not recognize it as valid layout file.

推荐答案

向androidTest添加xml资源非常困难.

It is tricky to add xml resources to androidTest.

Android Instrumentation测试会创建另一个APK，以针对您的原始应用程序运行测试.尽管您可以从主应用程序访问Context和对象，但是您无法修改应用程序生成的APK文件.

Android Instrumentation tests create another APK to run the tests against your original application. Although you can access your Context and objects from your main application, you cannot modify the generated APK file of your app.

这意味着您无法通过androidTest文件夹中的测试将其他布局xml放置到原始应用程序中.

That means you cannot put additional layout xml to your original application from tests that are in the androidTest folder.

或者，

• 您可以创建一个名为espresso的buildType.
• 然后，创建一个espresso文件夹，您可以在其中放置要添加的任何Java或Android资源.
  • 您甚至可以在那里修改您的AndroidManifest.
  • you can create a buildType called espresso.
  • Then, create an espresso folder where you can put any java or Android resource you want to add.
    • You can even modify your AndroidManifest there.

    您的build.gradle应该看起来像这样:

    Your build.gradle should look like this:

    android {
      testBuildType 'espresso'
    
      buildTypes {
        espresso.initWith(buildTypes.release)
      }
    }
    
    dependencies {
      espressoCompile 'somedependency' // you can even have special dependencies
    }
    

    围绕该风味运行浓缩咖啡测试时，您将有权访问添加的其他布局xml文件.

    When you run your espresso tests around that flavor, you will have an access to additional layout xml files you added.

    应如下所示:
