在黄瓜中运行测试时，为什么会收到NoSuchElementException

Question

I've spent the last few days writing tests in Cucumber. The tests I've written so far work fine, I've been able to click objects, sendkeys over. No problem.

I've now gotten to these page elements that cannot be found no matter what selector I use. I've tried using wait, but even though they are clearly visible on the page, they can't be accessed.

This is happening in both table row elements that I want to click on, and a text input I want to sendkeys to. I've included the latter below.

 <input type="text" name="EMPLOYEE_label" value="" class="" 
 onkeypress="return dtPk(event,this);" onkeydown="return dtKd(event,this);" 
 onchange="dltCh(this,'EMPLOYEE__test');" size="30" wbvalid="true" 
isresolving="false">

Here is the code I am using at present.

webdriver = new ChromeDriver();
WebDriverWait wait = new WebDriverWait(webdriver, 30);  
wait.until(ExpectedConditions.visibilityOfElementLocated(By
    .name("EMPLOYEE_label")));

JOptionPane.showMessageDialog(null, "WebDriver =" + webdriver);
WebElement empIDTextInput  = webdriver.findElement(By.name("EMPLOYEE_label"));
empIDTextInput.sendKeys("Bennett");
Thread.sleep(1000);
gtaProxyPage.clickFindButton().click();
Thread.sleep(1000);

gtaProxyPage.checkAssociateBox().click();
gtaProxyPage.loadTimesheet().click();
Thread.sleep(2000);

EDIT: I changed the code to this. It more closely resembles what I started with

     Thread.sleep(30000); 
     //this calls for the input element by className.
    gtaProxyPage.UserEntersNumberUnderTimesheet().click();
    gtaProxyPage.clickFindButton().click();
    gtaProxyPage.checkAssociateBox().click();
    gtaProxyPage.loadTimesheet().click();

This is the error I'm getting now

 org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"class name","selector":"input.triggerButton"}

I switched what I"m doing to click a button that opens a modal, and allows me to use a text field within that. But the button is not being seen.

This error message...

org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"class name","selector":"input.triggerButton"}

...implies that the no such element was found using the Locator Strategy with classname attribute as input.triggerButton .

Irespective of all the changes and manipulation done while publishing the relevant HTML within the question, to send a character sequence to the element:

<input type="text" name="EMPLOYEE_label" value="" class="" onkeypress="return dtPk(event,this);" onkeydown="return dtKd(event,this);" onchange="dltCh(this,'EMPLOYEE__test');" size="30" wbvalid="true" isresolving="false">

As the element is a dynamic element you have to induce WebDriverWait for the element to be clickable and you can use either of the following solutions:

• cssSelector :

   new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input[name='EMPLOYEE_label'][onchange*='EMPLOYEE__test']"))).sendKeys("Bennett"); 

• xpath :

   new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@name='EMPLOYEE_label' and contains(@onchange, 'EMPLOYEE__test')]"))).sendKeys("Bennett");
