如何使用Maven和courgette并行运行cucumber jvm测试场景？

Question

我正试图在Maven中基于cucumber标记运行一套JUnitCucumber特性。我可以让它们按顺序运行，但不能并行运行。我找到了一个名为小胡瓜的软件包，它可以帮我解决这个问题。

然而，我无法让测试运行，我看了github上的示例maven项目，它在Cucumber.class运行良好，但在西葫芦上抛出一个错误。

任何帮助将不胜感激。

我已在pom中包括以下内容

<repositories>
        <repository>
            <id>jcenter</id>
            <url>https://jcenter.bintray.com/</url>
        </repository>
</repositories>
<dependency>
    <groupId>io.github.prashant-ramcharan</groupId>
    <artifactId>courgette-jvm</artifactId>
    <version>2.4.4</version>
    <type>jar</type>
</dependency>

我是在召唤我的跑步者。

import courgette.api.CourgetteOptions;
import courgette.api.CourgetteRunLevel;
import courgette.api.junit.Courgette;
import cucumber.api.CucumberOptions;
import org.junit.runner.RunWith;

@RunWith(Courgette.class)
@CourgetteOptions(
        threads = 1,
        runLevel = CourgetteRunLevel.FEATURE,
        rerunFailedScenarios = false,
        showTestOutput = true,
        cucumberOptions = @CucumberOptions(features="src/test/resources/Features/Online/Regression/",
        plugin={"html:target/OD.html","json:target/OD.json"
                },tags={"@Max"},
                glue="com.Online"
                ))
 public class ONLINE_Regression_RunnerTest {
}

我得到以下错误。

Answer 1

有N种方法（如下所述）可以实现并行执行，其中一种最可取的方法是从V4.0开始使用Cucumber。0（特别是当我们必须在多个浏览器上而不是在多个操作系统上实现并行执行时）

1. cucumberJVM并行插件

为了实现4.0。0，请将下面的cucumber依赖项集与Maven配置一起使用，我们也将实现依赖项注入。

 <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-java</artifactId>
            <version>4.2.3</version>
        </dependency>

        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-junit</artifactId>
            <version>4.2.3</version>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>

        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>datatable</artifactId>
            <version>1.1.12</version>
        </dependency>

        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-testng</artifactId>
            <version>4.2.3</version>
        </dependency>

        <dependency>
            <groupId>io.cucumber</groupId>
            <artifactId>cucumber-picocontainer</artifactId>
            <version>4.2.3</version>
        </dependency>

Maven Surefire配置-

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>${maven-surefire.plugin.version}</version>
        <configuration>
            <parallel>methods</parallel>
            <threadCount>1</threadCount>
            <reuserForks>false</reuserForks>
            <testFailureIgnore>true</testFailureIgnore>
            <redirectTestOutputToFile>true</redirectTestOutputToFile>
            <includes>
                <include>**/*RunCukeTest.java</include>
            </includes>
        </configuration>
    </plugin>   

Answer 2

通过将依赖关系移动到pom的顶部，我能够消除冲突。似乎与测试ng依赖项存在冲突。

Answer 3

注意，从v4开始，Cucumber jvm就提供了并行选项。十、
