How to locate the Constraint validation text using Selenium and Java

544 Views Asked by At

I'm trying to make a Selenium test script that checks if a bootstrap validation popover appears when submitting a form containing a bad value.

My script below returns this error:

org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"css selector","selector":"#amount"}

Relevant code:

WebDriver driver = new ChromeDriver()
WebElement field = driver.findElement(By.id("amount"));  //errors here every execution
Boolean is_valid = (Boolean)WebUI.executeScript("return arguments[0].checkValidity();", field);

if (!is_valid) {
     //intentionally fail test
}

When I inspect the form field, I see the id equals amount, so why am I unable to find this element in Selenium?

enter image description here

Here's my full script:

WebUI.openBrowser('')

WebUI.navigateToUrl('Foo')

WebUI.setText(findTestObject('Object Repository/Page_bar/input_concat(Recipient, , s email address)_email'), '[email protected]')

WebUI.setText(findTestObject('Object Repository/Page_bar/input_Amount (USD)_amount'), '10001')

WebUI.click(findTestObject('Object Repository/Page_bar/button_Send Payment'))

 
WebDriver driver = new ChromeDriver() WebElement field =
driver.findElement(By.id("amount")); Boolean is_valid =
(Boolean)WebUI.executeScript("return arguments[0].checkValidity();", field);

if (!is_valid) { //intentionally fail test }

WebUI.closeBrowser()

According to the code you presenting in the question you are trying to access a web element before even opening the web page you are trying to work on.
In case you just omitted driver.get(the_page_url) and the code filling and submitting the form the error here may be caused by several causes:

  1. You are missing a delay. You can not locate the pop-up immediately after clicking the submit button, it takes some short time for pop-up to appear. The preferred approach here is to use Expected Conditions explicit waits, something like this:
WebDriverWait wait = new WebDriverWait(driver, 30);
WebElement field = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("amount")));
  1. The elements you are trying to access are inside an iframe.
    In this case you will have to switch into that iframe first in order to access elements inside it, as following:
driver.switchTo().frame(driver.findElement(By.id(the_iframe_id)));

and then continue with

WebDriverWait wait = new WebDriverWait(driver, 30);
WebElement field = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("amount")));

To give you better answer we have to see the page you are working on, to see all your actual code and to debug what actually happens there.

The popover is the HTML5 Constraint validation message which is the outcome of Constraint API's element.setCustomValidity() method.

To retrieve the text Value must be less than or equal to 10000. you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the locator strategies:

  • Using cssSelector:

    WebElement amount = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input#amount[name='amount']")));
System.out.println(amount.getAttribute("validationMessage"));

  • Using xpath:

    WebElement amount = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@id='amount' and @name='amount']")));
System.out.println(amount.getAttribute("validationMessage"));

As it is a <label> element as an alternative you can also try the following locator strategies:

  • Using cssSelector:

    WebElement amount = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("label[for='amount']")));
System.out.println(amount.getAttribute("validationMessage"));

  • Using xpath:

    WebElement amount = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//label[@for='amount']")));
System.out.println(amount.getAttribute("validationMessage"));

Instead you can also try for the visibilityOfElementLocated() as follows:

  • Using cssSelector:

    WebElement amount = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("label[for='amount']")));
System.out.println(amount.getAttribute("validationMessage"));

  • Using xpath:

    WebElement amount = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//label[@for='amount']")));
System.out.println(amount.getAttribute("validationMessage"));
