我是硒的新手。我正在尝试编写一个脚本来打开一个应用程序,输入用户名和密码并登录。我尝试在firefox中使用selenium IDE做同样的事情。它的工作。但是当我尝试使用selenium和TestNG(JAVA)时,我会发现以下错误:
org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: /html/body/form[1]/div[2]/table[2]/tbody/tr[4]/td/button (tried for 10 second(s) with 500 MILLISECONDS interval)

我的网页的HTML代码段是:
<table>
<tr>
<td>User Id: </td>
<td><input type="text" name="USER" id="USER" onfocus="this.style.border='2px solid #3BB9FF';" onblur="this.style.border='2px solid #737373'" /></td>
</tr>
<tr>
<td>Password: </td>
<td><input type="password" name="PASSWORD" id="PASSWORD" onfocus="this.style.border='2px solid #3BB9FF';" onblur="this.style.border='2px solid #737373'" /></td>
</tr>
<tr>
<td><input type="hidden" name="TARGET" id="TARGET" value="/epsweb/view/private/search/search.jsf" /></td>
</tr>
<tr>
<td><button name="Logon" type="submit" onfocus="this.style.border='2px solid #3BB9FF';" onblur="this.style.border='2px solid #737373'">Logon</button></td>
</tr>
</table>
我的TESTNG java代码:
public void userLogin(){
driver.get(baseURL + "login url");
//driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
//driver.findElement(By.id("USER")).sendKeys("aaa");
waitVar.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"USER\"]"))).sendKeys("aaa");
waitVar.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"PASSWORD\"]"))).sendKeys("123");;
// driver.findElement(By.name("USER")).sendKeys("aaa");
// driver.findElement(By.name("PASSWORD")).sendKeys("@123");
waitVar.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("/html/body/form[1]/div[2]/table[2]/tbody/tr[4]/td/button"))).click();
String strPageTitle = driver.getTitle();
}
我尝试使用多种组合但现在正在使用。我甚至尝试从firefox IDE复制代码并将其转换为java。 XPATH正在从萤火虫中解脱出来。
注意:表单元素在10秒之前可见。
更新:我尝试使用以下代码
WebElement myelement=driver.findElement(By.id("USER"));
String tag=myelement.getTagName();
System.out.println("====================="+tag);// ===============input
myelement.sendKeys("aaaa");
sysout专线正在打印。但是,当我使用sendKeys()方法时,它会抛出异常。

此问题仅在IE11中发生。我尝试使用chrome它可以正常工作。

我认为,你需要增加等待时间。从您的堆栈跟踪,您似乎使用10秒作为等待时间。在这么短的时间内,登录按钮不可见。增加等待时间可以解决您的问题。

@Nageswaranm,使用webdriver等待并使用id或name或cssSelector查找元素。在使用xpath查找webelement时,IE不如其他浏览器好。它在IE中很慢。同时增加webdriver等待30秒。希望这能解决问题。
