JUnit 4：如何创建一套套件？

Question

运行下面的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 { 
} 

堆栈跟踪

谢谢您的回答！

Answer 1

如果你使用eclipse;项目属性（右键单击项目）/ Java Build Path/Project/....添加您的测试项目..并再次运行:)

我终于找到了一种方法来实现我想通过运行junit 4套件套件，即在多模块项目的所有模块中运行所有测试。要做到这一点，请使用Johannes Link ClassPathSuite tool。

下载jar，将它安装到你的maven仓库中，创建一个allTests项目，这个项目取决于你的junit驻留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：

安装JAR到你的maven回购

创建ALLTESTS项目

该pom ...

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
<modelVersion>4.0.0</modelVersion> 
<groupId>com.prosveta.backend</groupId> 
<artifactId>alltests</artifactId> 
<version>0.0.1-SNAPSHOT</version> 
<dependencies> 
    <dependency> 
     <groupId>com.prosveta.backend</groupId> 
     <artifactId>serviceimpl</artifactId> 
     <version>1.0-SNAPSHOT</version> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>com.prosveta.backend</groupId> 
     <artifactId>daoimpl</artifactId> 
     <version>1.0-SNAPSHOT</version> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>com.prosveta.backend</groupId> 
     <artifactId>model</artifactId> 
     <version>1.0-SNAPSHOT</version> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>org.junit.extensions</groupId> 
     <artifactId>cpsuite</artifactId> 
     <version>1.2.5</version> 
     <type>jar</type> 
     <scope>compile</scope> 
    </dependency> 
    <dependency> 
     <groupId>junit</groupId> 
     <artifactId>junit</artifactId> 
     <version>4.8.2</version> 
     <type>jar</type> 
     <scope>compile</scope> 
    </dependency> 
</dependencies> 

添加依赖在Eclipse中...

这里是所有测试类

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“作为JUnit运行”。

当测试使用不在类路径中的类时，通常会引发此异常。只要确保你的类路径设置正确。
