如何并行执行黄瓜功能？

标签： maven selenium parallel-processing cucumber testng

我在src / test / resources / feature /中有以下功能文件（单独的功能文件），我想并行运行它们。就像：一个功能文件必须在chrome中执行，而另一个功能文件必须在另一个chrome实例中执行，如@Tags名称所述。

    @Regression 
    Scenario: Searching for HelpMate on Company Hompe page
    Given I navigate to application URL
    Then I verified title "Company - Production - Sign In" on Login Page 
    after 
    launched the URL
    When I type username as "defined in config" in username filed on Login 
    page
    And I type password as "defined in config" in password filed on Login 
    page
    And I click Login button on Login page
    And I wait for 15 seconds
    Then I verified title "Company - Production - My Applications" on 
    Login Page

    @Regression 
    Scenario Outline: Searching for different options on Company Home 
    page
    Given I navigate to application URL
    Then I verified title "Company - Production - Sign In" on Login Page 
    after launched the URL
    When I type username as "defined in config" in username filed on Login 
    page
    And I type password as "defined in config" in password filed on Login 
    page
    And I click Login button on Login page
    And I wait for 15 seconds

我使用的是cucumber-java 1.2.5版本，并且使用AbstractTestNGCucumberTests作为运行程序。我能够运行一个功能部件文件，但是当我尝试使用Cucumber-jvm-parallel-plugin v＃4.0.0和Maven surefire插件v＃2.40运行2个功能部件文件时，它没有初始化测试类 （错误：cucumber.runtime.CucumberException：cucumber.runtime.CucumberException：无法实例化com.cvs.stepdefinition.LoginPage类）

使用更新的黄瓜依赖项后，此错误消失了

cucumber-jvm-parallel-plugin--不再使用，因为最新版本的黄瓜库不再需要

我尝试从AbstractTestNGCucumberTests重写该方法，并将@DataProvider批注中的parallel属性设置为true，但仍然遇到相同的错误。

@DataProvider(parallel=true)
    public Object[][] features() {
        return testNGCucumberRunner.provideFeatures();

只有一个具有2个方案的功能文件，我希望这2个方案可以在两个不同的浏览器上并行运行。请帮助我解决这个问题。

3 个答案:

答案 0 :(得分：2)

关键点：：我们将要求您专门使用 Cucumber-JVM v4.xx 来实现并行执行，而无需在使用时使用Cucumber-jvm-parallel-plugin相当老的Cucumber依赖项（ v1.2.5 ）。

注意：：在以下实现中，我们将从TestNG.xml文件读取浏览器参数

首先-按照任何黄瓜v> = 4.0.0的正确一组io.cucumber依赖关系更新POM.xml，让我们选择v4.2.6 

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-picocontainer</artifactId>
    <version>4.2.6</version>
</dependency>

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-testng</artifactId>
    <version>4.2.6</version>
</dependency>

第二-根据您的框架需求自定义TestNGRunner类

package com.jacksparrow.automation.suite.runner;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Parameters;
import com.jacksparrow.automation.steps_definitions.functional.BaseSteps;
import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features = "classpath:features/functional/",
                     glue = {"com.jacksparrow.automation.steps_definitions.functional" },
                   plugin = { "pretty","json:target/cucumber-json/cucumber.json",
                            "junit:target/cucumber-reports/Cucumber.xml", "html:target/cucumber-reports"},
                   tags = { "@BAMS_Submitted_State_Guest_User" },
                   junit ={ "--step-notifications"},
                   strict = false,
                   dryRun = false,
               monochrome = true)

public class RunCukeTest extends Hooks {

}

第三-实现Hooks.java 

import org.testng.annotations.BeforeClass;
import org.testng.annotations.Parameters;
import cucumber.api.testng.AbstractTestNGCucumberTests;

public class Hooks extends AbstractTestNGCucumberTests {

    @Parameters({ "browser" })
    @BeforeTest
    public void setUpScenario(String browser){
        //BaseSteps.getInstance().getBrowserInstantiation(browser); your browser setup method
    }
}

第四-根据您的TestNGRunner类和框架的需要，在/ src / test / resources /下更新TestNG.xml。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Testng Cucumber Suite" parallel="tests" thread-count="2">
    <test name="SmokeTest">
        <parameter name="browser" value="chrome" />
        <classes>
            <class name="com.cvs.runner.TestSuiteRunner" />
        </classes>
    </test>
</suite>

第五-您将被设置为以下列任何一种方式使用TestNG运行自动化套件

 -    Run TestNG.xml directly from IDE 
 -    From CMD - mvn test -Dsurefire.suiteXmlFiles=src/test/resources/testng.xml
 -    From POM.xml - Using Surefire Plugin

<profiles>
   <profile>
      <id>selenium-tests</id>
      <build>
         <plugins>
            <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-surefire-plugin</artifactId>
               <version>3.0.0-M3</version>
               <configuration>
                  <suiteXmlFiles>
                     <suiteXmlFile>src/test/resources/testng.xml</suiteXmlFile>
                  </suiteXmlFiles>
               </configuration>
            </plugin>     
         </plugins>
      </build>
   </profile>
</profiles>

答案 1 :(得分：0)

您是否尝试在.xml文件中添加胎面数，我确实在其中添加了胎面数。

因此，您的.xml文件将是：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Testng Cucumber Suite" parallel="tests" thread-count="2">
  <test name="SmokeSuite">
  <classes>
    <class name="com.cvs.runner.TestSuiteRunner"></class>
  </classes>
  </test> 
 </suite>

（也尝试将parallel =“ tests”更改为并行方法。如果您在测试中使用优先级，则并行运行将无法工作）

答案 2 :(得分：0)

黄瓜4提供本机支持以并行运行方案（不按功能）。 您必须将pom.xml依赖项更新为最新的Cucumber版本。 黄瓜核心4.2.0，黄瓜Java 4.2.0，黄瓜Junit 4.2.0

在运行程序文件中，您添加了“ --thread 2”（如插件）。这将在2个线程中运行该方案。
