Cucumber 1.2.4 未找到步骤定义："You can implement missing steps with the snippets below" (2016)

Question

我正在尝试运行在类 UNIX 上使用 Maven 的 Cucumber（不幸的是我被迫使用 Windows，虽然 cmd.exe 有相同的结果）命令行:

mvn clean test -Dcucumber.options="src/test/resources/com/example/sqa/automation_cuke/pages/sample_test.feature"

结果：

Results :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
...
[INFO] --- exec-maven-plugin:1.2.1:java (default) @ sqa.automation_cuke ---
Feature: My animals Sample
  Sample test to use as basis for conversion

  Scenario: My animals           # sample_test.feature:4
    Given that I have my animals

1 Scenarios (1 undefined)
1 Steps (1 undefined)

You can implement missing steps with the snippets below:

@Given("^that I have my animals$")
public void that_I_have_my_animals() throws Throwable {
    // Write code here that turns the phrase above into concrete actions
    throw new PendingException();
}

我查看了所有排名靠前的 Google/SO 搜索以查找此错误消息和类似的错误消息。许多，例如 Cucumber can't find steps when running a single feature and Cucumber not finding step definitions，说要使用 -r 和 --require 参数指定我的步骤定义，但它们似乎在某些时候已从 Cucumber 中删除，因为我得到一个 Unknown option: -r错误。

许多其他答案说当@CucumberOptions glue 参数 定义不正确时会（奇怪地）发生此错误。但是我尝试了以下胶水并且 none 起作用了：

sqa.automation_cuke.pages path:sqa.automation_cuke.pages classpath:sqa.automation_cuke.pages com.example.sqa.automation_cuke.pages classpath:com.example.sqa.automation_cuke.pages path:com.example.sqa.automation_cuke.pages C:/development/cucumber-demo/src/main/java/com/example/sqa/automation_cuke/pages src/main/java/com/example/sqa/automation_cuke/pages classpath:C:/development/cucumber-demo/src/main/java/com/example/sqa/automation_cuke/pages classpath:src/main/java/com/example/sqa/automation_cuke/pages path:src/main/java/com/example/sqa/automation_cuke/pages C:\development\cucumber-demo\src\main\java\com\example\sqa\automation_cuke\pages src\main\java\com\example\sqa\automation_cuke\pages classpath:src\main\java\com\example\sqa\automation_cuke\pages path:src\main\java\com\example\sqa\automation_cuke\pages

我也试过：

在 -Dcucumber.options 中定义 --glue。
正在更改我的源代码目录结构 src/test/java/example/automation_cuke, src/main/java/example/automation_cuke, src/test/resources/example/automation_cuke，等等
放置我的 .feature 主要文件...资源。
@Given 中各种不同的文本，例如@Given("that I have my animals").

这是我的项目结构。我确保资源结构与代码的其余部分匹配 as per this answer:

sample_text.feature:

Feature: My animals Sample
  Sample test to use as basis for conversion

  Scenario: My animals
    Given that I have my animals

MySampleTest.java:

package com.example.sqa.automation_cuke.pages;

@RunWith(Cucumber.class)
@CucumberOptions(glue = {"com.example.sqa.automation_cuke.pages"})
public class MySampleTest {

    @Given("^that I have my animals$")
    public void that_I_have_my_animals() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        System.out.println("MySampleTest.that_I_have_my_animals() ran!");
        new MySample().printMySample();
        throw new PendingException();
    }
}

Answer 1

您需要为 cucumber 选项设置 features 属性才能正常工作。

将您的黄瓜选项注释替换为：

@CucumberOptions(features = {"classpath:com/example/sqa/automation_cuke/pages/sample_test.feature"}, glue = {"com.example.sqa.automation_cuke.pages"},

应该可以正常工作。如果没有，请更新 post。

更新：

SampleTestStepDefiniton.java

package com.example.sqa.automation_cuke.pages;

import cucumber.api.java.en.Given;

public class SampleTestStepDefinition {

    @Given("^that I have my animals$")
    public void that_I_have_my_animals() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        System.out.println("MySampleTest.that_I_have_my_animals() ran!");   
    }
}

MySampleTest.java

package com.example.sqa.automation_cuke.pages;

import org.junit.runner.RunWith;

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

@RunWith(Cucumber.class)
@CucumberOptions(glue = { "com.example.sqa.automation_cuke.pages" }, features = {
        "classpath:com/example/sqa/automation_cuke/pages/sample_test.feature" })
public class MySampleTest {

}

sample_test.feature

Feature: My animals Sample
  Sample test to use as basis for conversion

  Scenario: My animals
    Given that I have my animals

更新

我认为您项目的问题在于它无法在类路径中找到测试类（以及步骤定义类）。我不明白为什么你必须定义一个 CLASSPATH 系统变量。这可能是这个问题的原因。然而，PATH 变量应该保留并且不应包含对特定项目的任何引用

尝试删除 CLASSPATH 变量并用以下内容替换您的插件标签：

 <plugins>
    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <encoding>utf8</encoding>
            <source>1.7</source>
            <target>1.7</target>
        </configuration>
    </plugin>
     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <executions>
            <execution>
                <goals>
                    <goal>test-jar</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
    <plugin>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.18</version>
    </plugin>
</plugins>

我可以在多个 window 环境中使用 java 8 和 java 7 获得它运行。让我 posted！

Answer 2

您的设置非常复杂。想Gall’s Law, I would do a restart and build on something that works. A small getting started project is available at https://github.com/cucumber/cucumber-java-skeleton

Download/Clone 它和运行

mvn test

这应该会为您提供一个缺失的步骤，但它也应该为您提供一些已定义的步骤。查看源代码并在 src/test/java/skeleton/Stepdefs.java

中添加缺少的步骤

Answer 3

我也遇到了同样的问题，然后我意识到为 runner class 导入的包与 Step 定义不同 class

所以
如果对于 runner class 你正在使用如下的 io 包

import io.cucumber.junit.Cucumber;

import io.cucumber.junit.CucumberOptions;

那么你也应该在步骤定义中使用相同的 io 包

import io.cucumber.java.en.Given;

我导入API包的错误

import cucumber.api.java.en.Given;
