TestNg 并行执行在一个浏览器中连接输入测试数据

Question

我在一个类中有两个测试用例。当使用 TestNg 并行运行时，它会连接所有测试数据并将其放在一个浏览器中，而另一个浏览器为空。

硒版本：3.8.21 火狐：最新 测试：6.8.21

以下是代码

package cli;

import java.net.MalformedURLException;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class test1 {
    public WebDriver driver;

    @BeforeMethod
    public void setUp() throws MalformedURLException {
        System.out.println("@BeforeMethod: The annotated method will be run before each test method.");

    }

    @Test
    public void test() throws MalformedURLException, InterruptedException {
        driver = jenkinHub.hub();
        driver.get("https://www.google.com/");
        driver.findElement(By.xpath("//*[@id=\"lst-ib\"]")).sendKeys("Testing");
        System.out.println("This is current Url " + driver.getCurrentUrl());
        Thread.sleep(9000);
        driver.quit();

    }

    @Test
    public void NotTesting() throws MalformedURLException, InterruptedException {
        driver = jenkinHub.hub();
        driver.get("https://www.google.com/");
        driver.findElement(By.xpath("//*[@id=\"lst-ib\"]")).sendKeys("Not Testing");
        System.out.println("This is current Url " + driver.getCurrentUrl());
        Thread.sleep(9000);
        driver.quit();

    }

}

Answer 1

可能是因为您的driver 是类级别字段。当第一个测试方法初始化它 (driver = jenkinHub.hub()) 并尝试使用它时，另一个方法会重新为其分配新值，因此您的所有操作都使用相同的 WebDriver 实例完成。
尝试在这样的测试方法中移动它

@Test
public void test() throws MalformedURLException, InterruptedException {

    WebDriver driver = jenkinHub.hub(); // create WebDriver instance

    driver.get("https://www.google.com/");
    driver.findElement(By.xpath("//*[@id=\"lst-ib\"]")).sendKeys("Testing");
    System.out.println("This is current Url " + driver.getCurrentUrl());
    Thread.sleep(9000);
    driver.quit();

}

@Test
public void NotTesting() throws MalformedURLException, InterruptedException {

    WebDriver driver = jenkinHub.hub(); // create another WebDriver instance

    driver.get("https://www.google.com/");
    driver.findElement(By.xpath("//*[@id=\"lst-ib\"]")).sendKeys("Not Testing");
    System.out.println("This is current Url " + driver.getCurrentUrl());
    Thread.sleep(9000);
    driver.quit();

}

Answer 2

这里是如何并行执行的示例，您可以根据需要更改驱动程序实例化方法。试试这个，然后对你的代码进行相应的调整，它会打开两个 chrome 并在其中搜索测试项，并且不会连接。

package Grid
import java.net.MalformedURLException;
import java.net.URL;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class test1 {

    DesiredCapabilities caps;



    @BeforeMethod
    public void setUp() throws MalformedURLException {
        System.out.println("@BeforeMethod: The annotated method will be run before each test method.");
        caps = new DesiredCapabilities();
        caps = DesiredCapabilities.chrome();

    }

    @Test
    public void testing() throws MalformedURLException, InterruptedException {
        WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),caps);
        driver.get("https://www.google.com/");
        driver.findElement(By.xpath("//*[@id=\"lst-ib\"]")).sendKeys("Testing");
        System.out.println("This is current Url " + driver.getCurrentUrl());
        Thread.sleep(9000);
        driver.quit();

    }

    @Test
    public void NotTesting() throws MalformedURLException, InterruptedException {
        WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),caps);
        driver.get("https://www.google.com/");
        driver.findElement(By.xpath("//*[@id=\"lst-ib\"]")).sendKeys("Not Testing");
        System.out.println("This is current Url " + driver.getCurrentUrl());
        Thread.sleep(9000);
        driver.quit();

    }


    }

testng.xml 文件（与编辑包名相同）

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Regression Suite" verbose="1" parallel="methods" thread-count="4"> 

<test name="REgressionSuite">
