Junit Mockito 初始化错误

Question

我在网上到处都看了。我几乎尝试了所有方法，从删除 STS 到从我的站中删除所有代码并重新导入所有内容。我尝试了依赖项、构建路径、属性等，但仍然没有任何效果。

运行通过 CLI 在 Maven 上测试工作正常，其他团队成员没有这个问题，所以可能是我站上的一些配置。

问题：

当我尝试 debug/run 使用 JUnit v.4 在 STS 中进行单元测试时，我收到以下堆栈跟踪错误：

如果有人知道问题出在哪里...

这是 POM 的一部分：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.2.RELEASE</version>
    <relativePath>org.springframework.boot:spring-boot-starter-parent</relativePath>
</parent>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
    <dependency>
        <groupId>com.mockrunner</groupId>
        <artifactId>mockrunner</artifactId>
        <version>0.3.1</version>
    </dependency>

Answer 1

spring-boot-starter-test 1.4.2.RELEASE默认使用Mockito 1.10.19，org.mockito.internal.creation.jmock.ClassImposterizer在1.10.19。它现在在 org.mockito.internal.creation.cglib 包中。

从spring-boot-starter-test中排除org.mockito，如下：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.mockito</groupId>
                    <artifactId>mockito-core</artifactId>
                </exclusion>
            </exclusions>
</dependency>

并包含 mockito-all 1.9.5 作为依赖项：

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>1.9.5</version>
    <scope>test</scope>
</dependency>

Answer 2

在我的例子中，我在项目构建路径中添加了正确的 jars。但是测试用例的运行配置类路径有不同的 jar。更正 junit 测试的运行配置对我有用。

Answer 3

当有多个版本的 mockito 时会发生这种情况。排除由其他依赖项传递带来的 mockito 版本。

<exclusion>
 <artifactId>mockito-all</artifactId>
 <groupId>org.mockito</groupId>
 </exclusion>

这对我有效。
