Question

如果saleIdValueIs正确，但当saleIdValueIs数据不正确时，此代码工作正常。然后它显示一条错误消息“org.openqa.selenium.NoSuchElementException：无法找到元素”

        driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
        driver.findElement(By.xpath("//html/body/div/div/div[2]/div[2]/div/div/div/div/div/div/div/div/div[2]/div/div/div/div/div/fieldset/div/div/div/div[2]/div[2]/input")).sendKeys(saleIdValueIs);
        search_transaction_bt.click();
        boolean saleIdVisible=driver.findElementByXPath("/html/body/div/div/div[2]/div[2]/div/div/div/div/div/div/div/div/div/div/div").isDisplayed();
        String searchedSaleIdValue=saleIdValue.getText();
        System.out.println(saleIdVisible);
            if (saleIdVisible==true){
                    System.out.println("sale id  is  - "+saleIdValueIs+ "output is "+searchedSaleIdValue);
                    }       
                else{
                     System.out.println("error message is coming ");
                    boolean errorMessageDisplayTest= driver.findElement(By.xpath("/html/body/div[2]/div/div")).isDisplayed();
                    System.out.println(errorMessageDisplayTest);
                    boolean errorMessageVisible= driver.findElement(By.xpath("/html/body/div[2]/div/div")).isDisplayed();
                    System.out.println(errorMessageVisible);
                    driver.close();
                    }

你得到那个错误因为元素
driver.findElementByXPath("/html/body/div/div/div[2]/div[2]/div/div/div/div/div/div/div/div/div/div/div") 未显示，因此请使用isDisplayed而不是isElementPresent。下面是代码，如果有任何疑问，请允许我

boolean saleIdVisible= isElementPresent(By.xpath("/html/body/div/div/div[2]/div[2]/div/div/div/div/div/div/div/div/div/div/div"), driver);
if(Present)
{
System.out.println("sale id  is  - "+saleIdValueIs+ "output is "+searchedSaleIdValue);
 else{
System.out.println("error message is coming ");
boolean errorMessageDisplayTest= driver.findElement(By.xpath("/html/body/div[2]/div/div")).isDisplayed();
System.out.println(errorMessageDisplayTest);
boolean errorMessageVisible= driver.findElement(By.xpath("/html/body/div[2]/div/div")).isDisplayed();
System.out.println(errorMessageVisible);
driver.close();
}


public static boolean isElementPresent(By by, WebDriver driver) 
    {
      boolean present;
      try
        {
          driver.findElement(by);
          present = true;
        }catch (NoSuchElementException e)
        {
          present = false;
         }
     return present;
    }
