我用过
selenium.click("link=Sign In");
我尝试使用
selenium.click(".//*[@id='global-signin']/a");
两者都没有让我得到结果。
我收到如下错误: -
Element Link =“登录”未找到错误。
代码:
package package1_IdentifyPageOpened;
import com.thoughtworks.selenium.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
//import java.util.regex.Pattern;
public class PublicClass3 {
/**
* @param args
*/
Selenium selenium;
@Before
public void setUp() throws Exception {
selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://www.washingtonpost.com/");
selenium.start();
}
@Test
public void testTt4() throws Exception {
selenium.open("/");
selenium.click("link=Sign In");
selenium.type("name=MemberName", "mcXXX@gmail.com");
selenium.type("name=Password", "PPP@123");
selenium.click("name=submit");
selenium.waitForPageToLoad("30000");
}
@After
public void tearDown() throws Exception {
selenium.stop();
}
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
失败追踪:

之前我也遇到过同样的问题而且找不到元素'问题经常发生在硒中。这个问题的可能原因如下:
当你执行"点击元素"但是元素没有显示在页面中,也许它在加载的过程中,那么selenium会抛出异常:找不到元素。
元素的身份错误,可能是拼写错误或者selenium不支持身份识别方式。
我访问了您测试的网站http://www.washingtonpost.com
当您导出为Java时, SeleniumIDE
记录的测试用例始终不起作用。
这是我的代码:
public class Website extends SeleneseTestBase {
@BeforeMethod
public void setUp() throws Exception {
selenium = new DefaultSelenium("localhost", 4444, "*chrome", "http://www.washingtonpost.com/");
selenium.start();
}
@Test
public void testWebsite() throws Exception {
selenium.open("/");
waitFor("link=Sign In");
waitSecomd(3);
selenium.click("link=Sign In");
selenium.waitForPageToLoad("60000");
selenium.type("name=MemberName", "adasf@gmail.com");
selenium.type("name=Password", "adfasd");
selenium.click("name=submit");
selenium.waitForPageToLoad("60000");
}
@AfterMethod
public void tearDown() throws Exception {
selenium.stop();
}
public void waitFor(String locator) throws Exception {
for (int second = 0;; second++) {
if (second >= 60)
fail("timeout");
try {
if (selenium.isVisible(locator))
break;
} catch (Exception e) {}
Thread.sleep(1000);
}
}
public void waitSecomd(int n) throws Exception {
for (int second = 0;; second++) {
if (second >= 60)
fail("timeout");
try {
if (second > n - 1)
break;
} catch (Exception e) {}
Thread.sleep(1000);
}
}
}

<a>
元素是动态创建的(并且很糟糕 - 它会在很长一段时间后显示)并且Selenium无法找到它。如果你查看页面的源代码,你只能看到
<div id="utility-wrapper" data-tracking-type="utility">
<ul id="utility-links" class="inline-list">
<li id="global-signin" style="min-width:32px;"></li>
原因在于其中一个js文件中创建了登录链接,如下所示:
I.innerHTML = '<a href="' + D + "...a loong piece of URL..." + H + '">Sign In</a>';
Selenium可以找到动态创建的元素,但只能在创建之后才能找到它。
第一个解决方案,selenium.click("id=global-signin")
不起作用,因为找到并单击了该元素,但尚未包含实际链接(由js在一段时间后创建)。
解决方案是等待元素出现:
long targetTime = System.currentTimeMillis() + 10000; // 10 seconds from now
boolean found = false;
while (System.currentTimeMillis() < targetTime && !found) {
if (selenium.isElementPresent("link=Sign In")) {
selenium.click("link=Sign In");
found = true;
}
}
if (!found) {
throw new SeleniumException("Element not found!");
}
您甚至可以编写自己的click(String)
方法(以及其他方法,可以通过代码重复的简单方法,或通过Command pattern更难但更好的方式)将其合并用于每次搜索。
在Selenium 2 (WebDriver)中,通过Implicit wait:
会更容易// open Firefox
WebDriver driver = new FirefoxDriver();
// set the Implicit wait to 10 seconds
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("http://www.washingtonpost.com/");
driver.findElement(By.linkText("Sign In")).click();

这很难 - 我遇到的问题出现在第二页 - 除非我先选择目标定位器,否则Selenium无法在表单中输入任何数据。这是我的解决方案:
import java.util.concurrent.TimeUnit;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class LoginTest {
private static final String USERNAME = "username";
private static final String PASSWORD = "password";
private static final int PAUSE = 10;
@Test
public void testWebsiteTwo() throws Exception {
WebDriver driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(PAUSE, TimeUnit.SECONDS);
driver.get("http://www.washingtonpost.com/");
WebElement signin = driver.findElement(By
.cssSelector("li#global-signin a"));
signin.click();
// this line is crucial so that Selenium can enter the username / password
WebDriver.TargetLocator locator = driver.switchTo();
locator.frame(0);
WebElement name = driver.findElement(By.cssSelector("input#username"));
name.sendKeys(USERNAME);
WebElement password = driver.findElement(By.cssSelector("input#password"));
password.sendKeys(PASSWORD);
WebElement form = driver.findElement(By.cssSelector("form[name=form]"));
form.submit();
Thread.sleep(5000);
driver.close();
}
}
