【问题描述】：

尝试做一些自动化测试。当我尝试在命令行中执行 junit 时出现错误，

尝试的命令

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore C:/Users/path/workspace/CucumberConcept/src/ cucumber.CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar;C:/Users/path/workspace/CucumberConcept/src/ org.junit.runner.JUnitCore cucumber.CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore CucumberConcept.src.cucumber.CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore cucumber.CucumberRunner.CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore CucumberRunner.CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore CucumberRunner CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore CucumberRunner.java CucumberRunner

java -cp C:/Users/path/Downloads/selenium-java-3.0.1/lib/junit-4.12.jar org.junit.runner.JUnitCore CucumberRunner

Junit 代码：

package cucumber;

import org.junit.runner.RunWith;

import cucumber.api.junit.*;
import cucumber.api.CucumberOptions;


@RunWith(Cucumber.class)
@CucumberOptions(
        plugin = {"pretty","json:target/json/output.json","html:target/html/"},
        features = {"src/cucumber/"}
        )
public class CucumberRunner {
}

命令行

C:\Users\path\CucumberConcept\src>java -classpath C:/Users/path/lib/junit-4.12.jar;classes org.junit.runner.JUnitCore cucumber.CucumberRunner

【解决方案1】：

您的类路径已损坏。

你能使用像 Maven 这样的构建工具吗？这可能比手动构建类路径要容易得多。

克隆或下载 Cucumber 团队提供的 Java 框架，看看你能不能让它运行起来。可以在这里找到：https://github.com/cucumber/cucumber-java-skeleton

如果您无法使用 Maven、Ant 或 Gradle，请查看 build.xml 以获取有关如何手动构建类路径的一些灵感。
