线程"main"cucumber.runtime.CucumberException中的异常:未找到后端

Question

我正在使用Cucumber开发我的Selenium-JVM框架,并且在运行我的第一个功能时出现以下错误.

请帮忙.

我是如何推出这项功能的 -

1. 右键单击要素文件
2. 选择Run As - > Cucumber Feature

立即例外 -

Exception in thread "main" cucumber.runtime.CucumberException: No backends were found. Please make sure you have a backend module on your CLASSPATH.
    at cucumber.runtime.Runtime.<init>(Runtime.java:78)
    at cucumber.runtime.Runtime.<init>(Runtime.java:67)

    at cucumber.api.cli.Main.run(Main.java:24)
    at cucumber.api.cli.Main.main(Main.java:16)

我在代码中有什么 -

Launcher.java -

package cucumber;

import org.junit.runner.RunWith;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(format={"pretty","json:target/"} , features="/src/test/java/cucumber/features")
public class Launcher {

}

功能文件 -

Feature: it works demo

  Scenario: First test
    Given this is my step

我的JVM - 1.7

项目中只有这么多.

请帮忙.

Answer 1

如果在类路径中找不到"后端",则抛出此错误.每种支持的语言都有一个"后端"(例如,黄瓜-java,黄瓜-groovy等)

它可能是一个类路径错误,尽管如果黄瓜核心和黄瓜-java位于相同的位置似乎很奇怪.

Answer 2

确保您为Maven项目添加以下依赖项:

您可以将版本替换为最新版本或所需版本:

    <dependency>
        <groupId>info.cukes</groupId>
        <artifactId>cucumber-java</artifactId>
        <version>1.2.0</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>info.cukes</groupId>
        <artifactId>cucumber-junit</artifactId>
        <version>1.2.0</version>
    </dependency>
