Selenium中没有网格的多个WebDriver实例? [英] Multiple WebDriver instances in Selenium without Grid?

问题描述

是否可以在本地使用多个Selenium Webdriver而不使用Selenium网格同时运行多个测试?

Is it possible to use multiple selenium webdrivers locally without using selenium grid to run multiple test at the same time?

我通过调用new FireFoxDriver()创建多个实例，但是Windows中的会话似乎相互干扰.

I am creating multiple instances by calling new FireFoxDriver() but the sessions in the windows seem to interfere with each other.

驱动程序由下面显示的JUnit方法创建和销毁.对于每个测试类，都有一个WebDriver，但是每个测试用例都有不同的执行持续时间.在第一个Test类完成后，从该类中调用tearDownClass(). 抛出此异常:

The driver is created and destroyed by the JUnit-Methods shown below. For every Test-class there is one WebDriver but each testcase has a different execution duration. And after the first Test-class has finished and tearDownClass() from this class was called. This exception this thrown:

org.openqa.selenium.remote.SessionNotFoundException:在调用quit()后无法使用FirefoxDriver. 内部版本信息:版本:"2.39.0"，修订版:"14fa800511cc5d66d426e08b0b2ab926c7ed7398"，时间:"2013-12-16 13:18:38" 系统信息:主机:'T61'，ip:'127.0.1.1'，操作系统名称:'Linux'，os.arch:'i386'，os.version:'3.11.0-15-generic'，java.version :"1.7.0_51"

org.openqa.selenium.remote.SessionNotFoundException: The FirefoxDriver cannot be used after quit() was called. Build info: version: '2.39.0', revision: '14fa800511cc5d66d426e08b0b2ab926c7ed7398', time: '2013-12-16 13:18:38' System info: host: 'T61', ip: '127.0.1.1', os.name: 'Linux', os.arch: 'i386', os.version: '3.11.0-15-generic', java.version: '1.7.0_51'

@BeforeClass
public static void setUpClass() {
    driver = new FireFoxDriver();
}

@AfterClass
public static void tearDownClass() {
    driver.quit(); // this should only kill the current driver
}

推荐答案

然后尝试对不同的实例使用不同的驱动程序变量:

Then Try to use different driver variables for different instances:

例如:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class Testing 
{
    WebDriver driver1, driver2;
    @BeforeClass
    public void BeforeClass()
    {
        driver1 = new FirefoxDriver();
        driver2 = new FirefoxDriver();
    }
    @Test
    public void Test1() throws InterruptedException
    {
        driver1.get("http://www.google.com");
        driver2.get("http://gmail.com");

    }
    @org.testng.annotations.AfterClass
    public void AfterClass()
    {
        driver1.quit();
    }
}
