Question

在下面运行junit会引发异常。

import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

import com.prosveta.backend.daoimpl.AllDaoImplTests;

/**
 * Short desc.
 *
 * Longer desc.
 *
 * @author Jean-Pierre Schnyder
 *
 */
@RunWith(Suite.class)
@SuiteClasses({AllDaoImplTests.class,AllServiceImplTests.class})
public class AllBackendTests {
}

感谢您的回答！

Answer 1

我终于找到了一种方法，可以通过运行junit 4套件来实现我想要实现的目标，即在多模块项目的所有模块中运行所有测试。为此，请使用Johannes Link ClassPathSuite tool。

下载jar，将其安装在maven repo中，创建一个allTests项目，该项目取决于你的junits所在的其他项目，并创建一个AllTestClass。下面是一些代码和scn捕获来说明解决方案：

将jar安装到您的maven仓库中

创建一个allTests项目

pom ......

        <type>jar</type>
        <scope>compile</scope>
    </dependency>
</dependencies>

在Eclipse中添加依赖项...

enter image description here

，这是所有测试类

package com.prosveta.backend.serviceimpl;

import org.junit.extensions.cpsuite.ClasspathSuite;
import org.junit.runner.RunWith;

@RunWith(ClasspathSuite.class)
public class AllBackendTests {
}

你只是“以JUnit身份运行”。

Answer 2

如果你使用eclipse;项目的属性（右键单击项目）/ Java Build Path / Project / ....添加测试项目......然后再次运行：）

Answer 3

当测试使用不在类路径中的类时，通常会引发此异常。只需确保正确设置了类路径。

Answer 4

当我尝试使用spring框架执行某些测试时遇到了同样的问题。

如果您正在处理Maven项目，请尝试添加此依赖项：

<dependency>
    <groupId>org.hamcrest</groupId>
    <artifactId>hamcrest-library</artifactId>
    <version>1.3</version>
    <scope>test</scope>
</dependency>

这是我的整个pom.xml

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.hamcrest</groupId>
                <artifactId>hamcrest-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-library</artifactId>
        <version>1.3</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>4.3.0.RELEASE</version>
        <scope>test</scope>
    </dependency>
</dependencies>

此配置对我来说正常。
