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

我看到过类似问题的部分答案，但从未真正解决过问题.我已经把它归结为一个最小的应用程序来演示这个问题.

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.

我使用的是最新版本的 Android Studio (V2.2.1)我安装了以下 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. 更新了 build.gradle(应用):https://developer.android.com/training/testing/start/index.html#config-instrumented-tests

• 在defaultConfig下添加:
  

• Added under defaultConfig:
  

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

在依赖项下添加

Added under dependencies

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

项目是否同步以同步 Gradle

Did project sync to sync Gradle

在test"包下添加新的测试文件 - ExampleIntegrationTest.java(就在 ExampleUnitTest.java 旁边)

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

在新文件中，创建集成测试:https://developer.android.com/training/testing/unit-testing/instrumented-unit-tests.html

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 {
}

这就是问题所在 - 无法解析符号 AndroidJUnit4上线: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;

如果我输入 import 语句，我可以使用弹出式建议:
- 导入安卓.- 它显示支持作为选项"
- 导入 android.support.- 它显示测试"作为一个选项
- 导入 android.support.test.- 现在它只显示规则"作为选项

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

创建应用程序后，我确保它使用调试"变体

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

这是非常干净和干燥的.据我所知，这应该可行，但由于某种原因无法正确导入支持库.

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 仅用于单元测试的目录

或者，当您创建测试类时，通过在项目树的Android Instrumentation Tests"选项卡中选择新类来添加测试

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