Android Studio 2.1：错误：包org.junit不存在

问题描述

更新：这是一个错误并且已经报告，请注明：

  import org.junit.Test; 
 import static org.junit.Assert。*; 
 import static org.hamcrest.CoreMatchers。*; 
 
公共类RandomTestClass 
 {
 @Test 
 public void testTest（）
 {
 assertThat（4，is（4））; 
} 
} 
  

然而，当我去运行测试时，我得到：

我按照文档中的描述完全设置了我的gradle：

  dependencies {
 //必需 -  JUnit 4框架
 testCompile'junit：junit：4.12'
 //可选 -  Mockito框架
 testCompile'org.mockito：mockito-core：1.10.19'
} 
  

此问题的其他几个问题似乎表明缺少这些依赖关系。我有他们。

当我去运行测试时，您能想到我的本地单元测试没有找到junit文件的原因吗？

注意
我可以在编写代码时找到junit类。当我运行测试时，它只能找不到junit。

解决方案

看起来Gradle没有做到这一点。

解决了问题。

Update: Its a bug and it's been reported, please star:https://code.google.com/p/android/issues/detail?id=209832&thanks=209832&ts=1463161330

I'm setting up unit testing on Android studio.

I have read the documentation and set it up exactly as specified. I have my test folder set up as src/test/java

I've made a random test class:

import org.junit.Test;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;

public class RandomTestClass
{
    @Test
    public void testTest()
    {
        assertThat(4, is(4));
    }
}

However when I go to run my test I get:

I've set up my gradle EXACTLY as descibed in the docs:

dependencies {
    // Required -- JUnit 4 framework
    testCompile 'junit:junit:4.12'
    // Optional -- Mockito framework
    testCompile 'org.mockito:mockito-core:1.10.19'
}

The few other questions with this issue seemed to say these dependencies are missing. I have them.

Can you think of any reason my Local Unit Tests are not finding the junit file when I go to run the test?

NoteIt's able to find the junit classes when Im writing the code. It only can't find junit when I run the test.

解决方案

It looks like Gradle is not doing it's job.

Manually adding the jars fixed the problem.
