Cucumber - 未定义的步骤虽然已定义答案

【问题标题】：Cucumber - Undefined Steps Though definedCucumber - 未定义的步骤虽然已定义
【发布时间】：2018-08-28 16:06:42
【问题描述】：

我正在创建一个简单的 Selenium Cucumber 项目并使用“Lambda 表达式构造函数”方式为功能文件定义步骤，但是当我运行 CucumberTest 类时，我遇到了失败异常

有未定义的步骤！

我的 StepDefinition 低于 1

而功能文件是下面的一个

CucumberRunner 类如下：

如果我使用 Lambda 表达式，请建议我调用步骤定义文件有什么不同的方法吗？

【问题讨论】：

您使用的是哪个 IDE？
Eclipse...你知道我所问的解决方案吗？
您在控制台中遇到的错误还有什么？可以发一下吗
请将您的代码添加为文本，而不是图片
可能您的StepDef 类不在跑步者的glue 选项中定义的包中。

标签： selenium java-8 cucumber cucumber-java

【解决方案1】：

正如我在评论中已经提到的。选项 glue 需要一个包名列表，而不是目录。改变它从

glue = {"src/test/java/my.project.automation.wolfram_alpha" }

到

glue = {"my.project.automation.wolfram_alpha" }

会解决问题。

在下面找到有效的 sn-ps。假设如下结构

src/test/java/my/project/automation/wolfram_alpha/StepDef.java
src/test/java/my/project/automation/wolfram_alpha/cucumberTest.java
src/test/resources/wolfram.feature
pom.xml

cucumberTest.java

@CucumberOptions(
        features = { "src/test/resources/wolfram.feature" },

StepDef.java

package my.project.automation.wolfram_alpha;

import cucumber.api.java8.En;

public class StepDef implements En {
    public StepDef() {
        Given("URL of WolframAlpha" , () -> {

        });
        When("user logged in as {string} with {string}" , (String user, String password) -> {
            System.out.printf("When user logged in as {%s} with {%s}%n", user, password);

            System.out.printf("And user search for a {%s}%n", topic);
        });
        Then("results are displayed in a creative way" , () -> {
            System.out.println("Then results are displayed in a creative way");
        });
    }
}

wolfram.feature来自问题

使用mvn test 运行测试会产生以下输出。

Running my.project.automation.wolfram_alpha.cucumberTest
Configuring TestNG with: org.apache.maven.surefire.testng.conf.TestNG652Configurator@726f3b58
Given URL of WolframAlpha
When user logged in as {user} with {password}
And login is successful
And user search for a {IDOL}
Then results are displayed in a creative way

1 Scenarios (1 passed)
5 Steps (5 passed)
