Java Tomcat没有'；“找不到”；org.junit.Assert"；即使我的类路径中有JUnit JAR
我有一个问题，我已经看了很多，但仍然没有找到解决办法。我有一个测试用例，它在执行时向控制台发送一条消息。但是，即使使用JUnitJava Tomcat没有'；“找不到”；org.junit.Assert"；即使我的类路径中有JUnit JAR,java,maven,testing,junit,classnotfoundexception,Java,Maven,Testing,Junit,Classnotfoundexception,我有一个问题，我已经看了很多，但仍然没有找到解决办法。我有一个测试用例，它在执行时向控制台发送一条消息。但是，即使使用JUnitjars，它也表明我的项目中没有jars 我在Eclipse上用SpringMVC配置了一个Maven项目，并且已经使用向导手动将JUnitjar添加到类路径中。我还将依赖关系放在pom.xml中 在Maven依赖项中，我有另一个Junitjar，版本3.8.1。我认为向导（版本4）添加的jar与依赖项中的jar之间可能存在冲突。但事实并非如此 我已经尝试将版本4放在依

当我尝试执行测试用例时，控制台上会显示此错误：

有人知道我如何解决这个问题吗？
我尝试运行的测试用例是：
import static org.junit.Assert.*;
import java.io.IOException;
import java.lang.reflect.InvocationTargetException;
import org.junit.Test;
public class Runner {
@Test
public static String runClass() throws ClassNotFoundException, InstantiationException, IllegalAccessException, IOException, NoSuchMethodException, SecurityException, IllegalArgumentException, InvocationTargetException {
int expected = 9;
int obtained = 10;
String assertionError = null;
try {
assertEquals(expected, obtained);
System.out.println("This method is correct!");
}
catch (AssertionError ae) {
assertionError = ae.toString();
System.out.println(assertionError);
}
return "Executed!";
}
}

您的pom列出了JUnit3.81，但该版本的JUnit没有org.JUnit.Assert
。您可以使用JUnit的最新版本，但请注意，JUnit中最近进行的一些更改不向后兼容，因此您可能需要询问测试作者使用的版本
编辑：另外，pom.xml列出了范围为“test”的JUnit（即，仅作为测试的依赖项），这对于大多数项目来说是正确的，但是您的项目希望在生产代码中使用JUnit，所以将其更改为非测试依赖项
正如Nizet所说，示例测试不是有效的测试。您到底想做什么。堆栈跟踪表明您似乎希望在生产、部署的代码中使用JUnit，而不是在单元测试中使用JUnit。发布的代码显示，您正试图将测试注释应用于静态方法，返回一个字符串，这根本不是您定义测试的方式。最后，您似乎正在使用Maven，但同时您正在处理eclipse类路径，尽管类路径应该由pom文件负责。所有这些都没有多大意义。你想做什么？@JBNizet这是使用教授开发的测试用例来评估编程任务。它将从教授那里加载测试用例类并将其放入目录中，当学生提交代码时，我的应用程序将使用教授的测试用例。但是我想从测试用例中获取要存储的消息，所以我在测试中使用字符串。我展示的这个类只是一个例子，因为我甚至不能加载s
