java - TestNG 与 selenium 驱动工厂并行执行

Question

尝试为我正在构建的框架设置驱动程序工厂作为学习工具。然而，我正在努力在 testng 中并行执行测试类。

我正在使用surefire插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.20.1</version>
        <configuration>
            <properties>
                <suiteXmlFiles>
                    <suiteXmlFile>src/main/resources/master.xml</suiteXmlFile>
                    </suiteXmlFiles>
            </properties>
        </configuration>
        <dependencies>
            <dependency>
                <groupId>org.aspectj</groupId>
                    <artifactId>aspectjweaver</artifactId>
                    <version>${aspectj.version}</version>
            </dependency>
        </dependencies>
</plugin>

我使用的testng版本是:

<dependency>
    <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.9.10</version>
        <scope>test</scope>
</dependency>

master.xml如下:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Parallel test suite" parallel="classes" thread-count="2">
    <test name="Test 1">
        <classes>
            <class name="testsuite.TestCase1"/>
            <class name="testsuite.TestCase2"/>
        </classes>
    </test>
</suite>

为了在此处发布，我简化了驱动程序工厂:

public class DriverFactory
{
    //protected WebDriver driver;

    private DriverFactory()
    {
        //Do-nothing..Do not allow to initializethis class from outside
    }
    private static DriverFactory instance = new DriverFactory();

    public static DriverFactory getInstance()
    {
        return instance;
    }

    ThreadLocal<WebDriver> driver = new ThreadLocal<WebDriver>() // thread local driver object for webdriver
    {
        @Override
        protected WebDriver initialValue()
        {
            System.setProperty("webdriver.chrome.driver",
                    "src/main/resources/chromedriver.exe");
            return new ChromeDriver(); // can be replaced with other browser drivers
        }
    };

    public WebDriver getDriver() // call this method to get the driver object and launch the browser
    {
        return driver.get();
    }

    public void removeDriver() // Quits the driver and closes the browser
    {
        driver.get().quit();
        driver.remove();
    }
}

使用以下mvn命令运行:

mvn 干净测试

我知道这对我来说是一件愚蠢的事情，因为我阅读了几乎所有与此相关的教程、博客文章和文档。

非常感谢任何帮助，即使只是为我指出正确的方向。

TestNG 允许您并行运行测试，包括 JUnit 测试。为此，您必须设置并行参数，并且如果默认值 5 不够，则可以更改 threadCount 参数。您必须设置配置参数:

 <configuration>
      <parallel>methods</parallel>
      <threadCount>10</threadCount>
  </configuration>

给你:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.20.1</version>
        <configuration>
            <parallel>methods</parallel>
            <threadCount>10</threadCount>
            <properties>
                <suiteXmlFiles>
                    <suiteXmlFile>src/main/resources/master.xml</suiteXmlFile>
                    </suiteXmlFiles>
            </properties>
        </configuration>
        <dependencies>
            <dependency>
                <groupId>org.aspectj</groupId>
                    <artifactId>aspectjweaver</artifactId>
                    <version>${aspectj.version}</version>
            </dependency>
        </dependencies>
</plugin>

更新

尝试以下操作

<suite name="Parallel test suite" parallel="classes" thread-count="2">
<test name="Test 1">
    <classes>
        <class name="testsuite.TestCase1"/>
    </classes>
</test>
<test name="Test 2">
    <classes>
        <class name="testsuite.TestCase2"/>
    </classes>
</test>
