Question

我为雅虎网站写了一个selenium测试。在这个测试中，我正在测试Yahoo News。但是这段代码抛出了异常。那么请解决问题？我正在使用Eclipse IDE和Firefox作为浏览器。

代码：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.Wait;
import org.openqa.selenium.support.ui.WebDriverWait;


public class Tests {

    WebDriver driver;
    Wait<WebDriver> wait;
    boolean result;

    Tests() {
        driver = new FirefoxDriver();
        wait = new WebDriverWait(driver, 30);
        driver.get("http://www.yahoo.com/");
    }

    public static void main(String arg[]) {
        new Tests().news();
    }

    public boolean news() {
        try {
            System.out.print("Testing News... ");
            driver.findElement(By.linkText("https://www.yahoo.com/news/")).click();
            driver.findElement(By.partialLinkText("/news/world/")).click();
            wait.until(new ExpectedCondition<Boolean>() {
                public Boolean apply(WebDriver webDriver) {
                    return webDriver.findElement(By.id("th-title")) != null;
                }
            });
            return driver.findElement(By.id("th-title")).getText().contains("World");
        }
        catch(Exception exp) {
            exp.printStackTrace();
            return false;
        }
    }
}

例外：

Answer 1

请检查Yahoo page。
请按Ctrl-F并尝试查找文字：“https://www.yahoo.com/news/”＆gt;
那里没有这样的文字。

但是如果你查看这个页面的html源代码，你会发现这个带有href的A标签attriibutte =“”https://www.yahoo.com/news/“：

<a class="C(#fff) Td(n) Td(u):h" href="https://www.yahoo.com/news/" 
 data-reactid=".pgwo63s1xy.$tgtm-UH-0-Header.1.0.0:$news.0">News</a>

但此链接的“链接文字”不是“https://www.yahoo.com/news/”，而是“新闻”。
By＃linkText方法正在寻找链接文字（在这种情况下“新闻”），而不是href attributte。

您需要替换此命令：

 driver.findElement(By.linkText("https://www.yahoo.com/news/")).click();

这一个：

driver.findElement(By.linkText("News")).click();
