public void clickElement(WebElement slocator)
{
try
{
slocator.click();
System.out.println(slocator+" clicked");
}
catch(Exception e)
{
System.out.println(slocator+ " NOT clicked");
}
}
}
所以我有这个简单的方法可以点击selenium中的链接。如果我这样做：
slocator.click();
然后一切都运行良好。但是，当我把它们放在try和catch块中时，它给了我这个错误：

抱歉，我将发布所有代码。我害怕引起混乱。这是将调用CommonMethods的类：
package com.OSCom.page;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.How;
import com.OSCom.CommonMethods.CommonMethods;
public class HomePage {
private WebDriver driver;
CommonMethods CM;
@FindBy(how=How.LINK_TEXT, using = "log yourself in")
private WebElement logIn;
public HomePage(WebDriver driver)
{
this.driver = driver;
}
public void clickLogIn() throws InterruptedException
{
CM = new CommonMethods(driver);
CM.clickElement(logIn);
}
}
这是我使用testNg运行的测试类
