我试图点击网站上的登录链接alibaba.com
这是我的测试用例：
public class TestCase {
public static void main(String[] args) throws InterruptedException {
// TODO Auto-generated method stub
String URL = "http://www.alibaba.com/";
WebDriver driver;
System.setProperty("webdriver.chrome.driver",
"D:\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.get(URL);
Thread.sleep(2000);
SignIn.SignIn_click(driver).click();
}
}
这是对象类，其中在am中定位Web元素
package PageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class SignIn {
private static WebElement element = null;
public static WebElement SignIn_click(WebDriver driver) {
element = (new WebDriverWait(driver, 10)).until(ExpectedConditions
.visibilityOfElementLocated(By
.xpath("//a[@data-val='ma_signin']")));
element = driver.findElement(By
.xpath("//a[@data-val='ma_signin']"));
return element;
}
}
但是当我运行这段代码时，我总是得到这个异常：
Exception in thread "main" org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: //a[@data-val='ma_signin'] (tried for 10 second(s) with 500 MILLISECONDS interval)

请帮帮我。
请尝试以下操作：
package PageObjects;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class SignIn {
private static WebElement element = null;
public static WebElement SignIn_click(WebDriver driver) throws InterruptedException {
element = driver.findElement(By.xpath("id('J_SC_header')/header/div[2]//span[1]/a[@data-val='ma_signin']"));
while (!isDisplayed(element))
{
Thread.sleep(3000);
System.out.println("Element is not visible yet");
}
return element;
}
public static boolean isDisplayed(WebElement element) {
try {
if(element.isDisplayed())
return element.isDisplayed();
}catch (NoSuchElementException ex) {
return false;
}
return false;
}
}
以下是你问题的答案：
您构造的xpath//a[@data-val='ma_signin']不是唯一的。xpath匹配3个节点。如果您想单击登录按钮，您可以考虑使用这个唯一的xpath：
//div[@id='J_SC_header']//div[@class='sc-hd-row sc-hd-main']//a[@rel='nofollow'][@data-val='ma_signin']
public static void waitVisibilityOfElementLocated(WebDriver driver, String locator) {
String key = "";
WebElement element = null;
try {
key = Utility.fetchLocatorKey(locator);
} catch (Exception e) {
System.out.println("Exception in getText method, " + e.getMessage());
}
if (key.endsWith("id")) {
WebDriverWait wait = new WebDriverWait(driver, 60);
element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id(locator)));
} else if (key.endsWith("cssselector")) {
WebDriverWait wait = new WebDriverWait(driver, 60);
element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector(locator)));
} else if (key.endsWith("linktext")) {
WebDriverWait wait = new WebDriverWait(driver, 60);
element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.linkText(locator)));
} else if (key.endsWith("xpath")) {
WebDriverWait wait = new WebDriverWait(driver, 60);
element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(locator)));
}
}
