我试图单击alibaba.com网站上的“登录”链接
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();
}
}
这是定位Web元素的对象类
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，当我运行此代码时，总是会遇到以下异常:
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)

请帮我。
最佳答案
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;
}
}
