本文介绍了不能使用Spring进行JUnit测试的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的测试定义如下：
package com.mytest;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class SpringTestCase {
@Test
public void testSave_success() {
fail("Not implemented");
}
}
我的目的是运行此测试并失败！
My intention is to just run this test and fail!
我的测试弹簧配置文件位于：
My test's spring configuration file is located in:
/com/mytest/SpringTestCase-context.xml
我的spring配置文件的内容如下：
The contents of my spring configuration file are as follows:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
</beans>
当我运行测试时，我得到以下异常：
When i run my test i get the following exception:

我正在使用mave n具有以下弹簧版本集：
I am using maven with the following spring version set:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.1.1.RELEASE</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
如果有任何帮助，我将不胜感激。
I would be grateful for any help on this.
编辑：
有人建议添加spring-core依赖项。虽然我怀疑它是否会有所作为，但我确实添加了它，这就是异常的样子：
Someone suggested adding spring-core dependency as well. Although i doubt if it would make a difference, i did add it and here's what the exception looks like:

推荐答案
这是你的整个pom吗？如果不是，你需要包含spring-core，因为spring-test只将它作为可选依赖项
Is that your whole pom? if not you need to include spring-core, as spring-test only has it as an optional dependency
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${project.version}</version>
<optional>true</optional>
</dependency>
maven上下文中的可选方式：
What optional means in the context of maven:
您可能需要包含其他弹簧库，具体取决于您最终测试的内容。
You may need to include other spring libraries depending upon what you end up testing.
我能够让您的测试运行，包括以下Spring依赖项以及spring-测试：
I was able to get your test running including the following Spring dependencies along with spring-test:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.1.1.RELEASE</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.1.1.RELEASE</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.1.1.RELEASE</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.1.1.RELEASE</version>
<scope>test</scope>
</dependency>
