Android Studio集成测试无法解析符号AndroidJUnit4 [英] Android Studio Integration test cannot resolve symbol AndroidJUnit4

问题描述

我已经看到过类似问题的部分答案，但是从来没有真正解决过这个问题的答案.我将其简化为一个最小的应用程序以演示该问题.

I've seen partial answers to similiar issues but never one that actually solved the problem. I've boiled this down to a minimal app to demonstrate the issue.

我正在使用最新版本的Android Studio(V2.2.1) 我已安装以下SDK:

I'm using the most current version of Android Studio (V2.2.1) I have the following SDK's installed:

• Android SDK工具v25.1.6
• Android SDK平台工具v23.1
• Android SDK Build-tools v23.0.3

• Android支持存储库v32

• Android SDK Tools v25.1.6
• Android SDK Platform-tools v23.1
• Android SDK Build-tools v23.0.3

• Android Support repository v32

1. 使用向导创建新的Android应用

2. 更新后的build.gradle(应用程序)，每个版本:

3. 在defaultConfig下添加:
   

   • Added under defaultConfig:
     

   • testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"

   在依赖项下添加了
   

   Added under dependencies
   

   • androidTestCompile'c​​om.android.support:support-annotations:23.0.1'<-更改为23.4.0以匹配新生成的应用程序
     
   • androidTestCompile'c​​om.android.support.test:runner:0.4.1'
     
   • androidTestCompile'c​​om.android.support.test:rules:0.4.1'
     

   是否已同步项目以同步Gradle

   Did project sync to sync Gradle

   在测试"包下，添加新的测试文件-ExampleIntegrationTest.java(在ExampleUnitTest.java旁边)

   Under the "test" package add new test file - ExampleIntegrationTest.java (right next to ExampleUnitTest.java)

   在新文件中，根据以下内容创建集成测试:

   In the new file, created integration test per: https://developer.android.com/training/testing/unit-testing/instrumented-unit-tests.html

import android.support.test.runner.AndroidJUnit4;
import android.test.suitebuilder.annotation.SmallTest;

import org.junit.runner.RunWith;


@RunWith(AndroidJUnit4.class)
@SmallTest
public interface ExampleIntegrationTest {
}

---

这是问题所在-无法解析符号AndroidJUnit4 在线:import android.support.test.runner.AndroidJUnit4;

---

This is where the problem comes up - cannot resolve symbol AndroidJUnit4 On the line: import android.support.test.runner.AndroidJUnit4;

如果输入import语句，则可以使用弹出式建议:
-导入android. -它显示支持作为选项"
-导入android.support. -它显示测试"作为选项
-导入android.support.test. -现在仅显示"rule"作为规则


If I type the import statement I can use the popup suggestions:
- import android. - It shows "support as option"
- import android.support. - It shows "test" as an option
- import android.support.test. - Now it only shows "rule" as a option


创建应用后，请确保其使用的是调试"变体

After I create the app I make sure it's using the "debug" variant

这很漂亮，很干.据我所知，这应该可行，但是由于某种原因，支持库无法正确导入.

This is pretty cut and dry. As far as I can tell this should work,, but the support library for some reason isn't getting imported correctly.

推荐答案

通过将测试添加到

• /app/src/androidTest目录而不是
• /app/src/test目录，仅用于单元测试

或者，当您创建测试类时，通过在项目"树的"Android Instrumentation测试"标签中选择新的类来添加测试

Or, when you create the test class, add the test by selecting new class when in "Android Instrumentation Tests" tab of the Project tree
