如何使用 TestNg 和 eclipse 在其他浏览器完成后在多个浏览器中运行 Selenium webdriver 测试用例

我想在所有多个浏览器中运行 selenium webdriver 测试用例但不是并行的是否可以在不使用xml和selenium网格的情况下在所有多个浏览器中运行测试用例。我们可以通过使用注释和java类来做到这一点。我希望我的测试用例应该首先在firefox中执行，然后在firefox中执行完成后应该在chrome中开始执行等等。

我已经尝试过这段代码，但使用 xml 并行执行。

CrossBrowserScript.java

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class CrossBrowserScript {

    WebDriver driver;

    /**
     * This function will execute before each Test tag in testng.xml
     * @param browser
     * @throws Exception
     */
    @BeforeTest
    @Parameters("browser")
    public void setup(String browser) throws Exception{
        //Check if parameter passed from TestNG is 'firefox'
        if(browser.equalsIgnoreCase("firefox")){
        //create firefox instance
            driver = new FirefoxDriver();
        }
        //Check if parameter passed as 'chrome'
        else if(browser.equalsIgnoreCase("chrome")){
            //set path to chromedriver.exe
            System.setProperty("webdriver.chrome.driver",".\\chromedriver.exe");
            //create chrome instance
            driver = new ChromeDriver();
        }
        //Check if parameter passed as 'IE'
                else if(browser.equalsIgnoreCase("ie")){
                    //set path to IE.exe
                    System.setProperty("webdriver.ie.driver",".\\IEDriverServer.exe");
                    //create IE instance
                    driver = new InternetExplorerDriver();
                }
        else{
            //If no browser passed throw exception
            throw new Exception("Browser is not correct");
        }
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    }

    @Test
    public void testParameterWithXML() throws InterruptedException{
        driver.get("http://demo.guru99.com/V4/");
        //Find user name
        WebElement userName = driver.findElement(By.name("uid"));
        //Fill user name
        userName.sendKeys("guru99");
        //Find password
        WebElement password = driver.findElement(By.name("password"));
        //Fill password
        password.sendKeys("guru99");
    }
}

testngCrossBrowser.xml

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

使用 JUnit，您可以创建 MethodRule (http://junit.org/apidocs/org/junit/rules/MethodRule.html http://junit.org/apidocs/org/junit/rules/MethodRule.html）这将在所有浏览器中运行测试。

Example:

public class ManyBrowsers implements MethodRule {

public static WebDriver driver;

@Override
public Statement apply(final Statement base, FrameworkMethod method, Object target) {
    return new Statement() {

        @Override
        public void evaluate() throws Throwable {
            //RUN FIREFOX
            driver = new FirefoxDriver();
            base.evaluate();
            driver.quit();

            //RUN CHROME
            File f = //PATH to CHROME DRIVER
            System.setProperty("webdriver.chrome.driver", f.getAbsolutePath());
            driver = new ChromeDriver();
            base.evaluate();
            driver.quit();
        }
    };
}

}

测试示例：

public class VisitGoogle {

@Rule
public ManyBrowsers browsers = new ManyBrowsers();

@Test
public void test() {
    ManyBrowsers.driver.navigate().to("https://www.google.com/");
}

}
