java – WebDriver打印错误的条件语句

我正在学习WebDriver并试图查看demoaut网站上的链接.循环中的代码应该通过其标题识别“正在构建”页面,打印出第一行,然后返回到基本URL.但这不会因某种原因发生.它获得的第一个“正在建设中”链接(特色度假目的地)不被识别,提示打印错误的行,然后由于NoSuchElementException而不是返回它崩溃,因为它正在查找错误的链接页.为什么会这样？为什么它不根据“正在建设中”页面的标题行事？

import java.util.List;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;

public class CheckLinks {

public static void main(String[] args) {
    String baseUrl = "http://newtours.demoaut.com/";
    System.setProperty("webdriver.gecko.driver", "C:\\Workspace_e\\geckodriver.exe");
    WebDriver driver = new FirefoxDriver();
    String underConsTitle = "Under Construction: Mercury Tours";
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

    driver.get(baseUrl);
    List<WebElement> linkElements = driver.findElements(By.tagName("a"));
    String[] linkTexts = new String[linkElements.size()];
    int i = 0;

    //extract the link texts of each link element
    for (WebElement e : linkElements) {
        linkTexts[i] = e.getText();
        i++;
    }

    //test each link
    for (String t : linkTexts) {
        driver.findElement(By.linkText(t)).click();
        if (driver.getTitle().equals(underConsTitle)) {
            System.out.println("\"" + t + "\""
                    + " is under construction.");
        } else {
            System.out.println("\"" + t + "\""
                    + " is working.");
        }
        driver.navigate().back();
    }
    driver.quit();
}

}

解决方法:

单击第一个链接后,即使您返回到页面,linkTexts中的所有引用也将变为陈旧…您需要做的是将所有href存储在List中,然后导航到每个href并检查页面的标题.

我会这样写的……

public class CheckLinks
{
    public static void main(String[] args) throws UnsupportedFlavorException, IOException
    {
        String firefoxDriverPath = "C:\\Users\\Jeff\\Desktop\\branches\\Selenium\\lib\\geckodriver-v0.11.1-win32\\geckodriver.exe";
        System.setProperty("webdriver.gecko.driver", firefoxDriverPath);
        WebDriver driver = new FirefoxDriver();
        driver.manage().window().maximize();

        String baseUrl = "http://newtours.demoaut.com/";
        driver.get(baseUrl);
        List<WebElement> links = driver.findElements(By.tagName("a"));
        List<String> hrefs = new ArrayList<>();
        for (WebElement link : links)
        {
            hrefs.add(link.getAttribute("href"));
        }
        System.out.println(hrefs.size());
        String underConsTitle = "Under Construction: Mercury Tours";
        for (String href : hrefs)
        {
            driver.get(href);
            System.out.print("\"" + href + "\"");
            if (driver.getTitle().equals(underConsTitle))
            {
                System.out.println(" is under construction.");
            }
            else
            {
                System.out.println(" is working.");
            }
        }
        driver.close();
        driver.quit();
    }
}
