无法使用 Spring 进行 JUnit 测试

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");
    }
}

我的目的是运行这个测试并失败！

我的测试的 spring 配置文件位于：

 /com/mytest/SpringTestCase-context.xml

我的spring配置文件内容如下：

<?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，出现以下异常：

我正在使用带有以下 spring 版本集的 Maven：

<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>

如果您对此有任何帮助，我将不胜感激。

EDIT:

有人建议也添加 spring-core 依赖项。尽管我怀疑它是否会产生影响，但我确实添加了它，下面是异常的样子：

这就是你的全部pom吗？如果没有，您需要包含 spring-core，因为 spring-test 仅将其作为可选依赖项

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-core</artifactId>
  <version>${project.version}</version>
  <optional>true</optional>
</dependency>

可选在 Maven 上下文中意味着什么：

表示使用该库时依赖项是可选的。虽然如果库在其他地方使用，依赖项的版本将被考虑到依赖项计算，但它不会被传递。

您可能需要包含其他 spring 库，具体取决于您最终测试的内容。

我能够让您的测试运行，包括以下 Spring 依赖项以及 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>
