Cucumber + Java + Spring Boot = 从 jar 运行时没有后端错误

如同这个旧帖子 https://stackoverflow.com/questions/44069165/cucumber-no-backend-found-when-running-from-spring-boot-jar我有一个使用 Spring boot 和 Cucumber 的 Java 应用程序。

该应用程序的目的是使用 Selenium 来验证我的团队使用的一些工具，因此我的测试都在主要范围内。

测试在 IDE 中运行良好，但是当我打包 jar 并尝试运行它时，我得到了未找到后端。请确保您的 CLASSPATH 上有后端模块。

经过一番搜索，我配置了 spring-boot-maven-plugin 来解压 cucumber-java 依赖项。 这修复了“无后端”错误，但是现在，当我运行 jar 时，我在控制台上打印了我的功能文件，但没有测试真正执行（它过得太快了，我什至引入了一个错误，但无论如何它都成功完成了） 。

我的主要课程：

@SpringBootApplication
public class ExecutableMain implements CommandLineRunner {

    public static void main(String[] args) {
        SpringApplication.run(ExecutableMain.class, args);
    }

    @Override
    public void run(String... args) {
        for (String arg : args) {
            ...
        }
        Result result = JUnitCore.runClasses(Test1.class, Test2.class, Test3.class);
        if (result.wasSuccessful()) {
            System.out.println("Success!");
        } else {
            System.out.println("Failure!");
            for (Failure failure : result.getFailures()) {
                System.out.println(failure.toString());
            }
        }
    }
}

其中一项测试？

@RunWith(Cucumber.class)
@CucumberOptions(
        plugin = {"pretty", "html:target/cucumber-test1", "json:target/cucumber-test1/cucumber.json"},
        glue = {"cucumber.test1", "cucumber.steps"},
        features = "src/main/resources/cucumber/test1/"
        )
public class Test1 {

}

控制台结果：
