How to check if all elements of a PageObject are valid (Java, Serenity, Cucumber)

Question

I am writing scenario test cases in cucumber and I want to check if all the elements of a PageObject are valid and selenium can interact with them, before I run the test. I want to avoid running my multi-step, long test case just to get to the last page and get an exception that an element is not found. I wanted to be able to test my PageObject after I write it, so I can be sure that all the elements are reachable (before running the long test..).

The website I am working on does not have consistent id tags and using @FindBy() sometimes takes some playing around with. I am trying to make a simple process of:

1. Navigate to the PageObject url
2. check if all elements in the PageObject are reachable by selenium

Do you know of a way to access all the PageObjects elements with out making a method for each one? A method that initializes all the elements?

Answer 1

After trying a number of different ways, I used reflection within the class to pull all fields, and then used .isPresent(); to check if the element is on the page. This solution requires this method to be placed in each class that you want to test, which I was trying to avoid.

Solution:

SuiteRunner

@RunWith(CucumberWithSerenity.class)
@CucumberOptions(features = "src/test/resources/features/checkElems")
public class RegressionTestSuite {}

Feature File: CanFindElems.feature

Feature: Check if WebPage Object elements can be found

  Scenario: Check if the page's elements are reachable
    Given navigate to webpage
    Then check page elements

Test Class

public class CanFindElemsTest {

  // Change the class
  ClassYouAreTesting page;

  @Given("^navigate to webpage$")
  public void navigate_to_webpage() throws Exception {

    page.open();
  }


  @Then("^check page elements$")
  public void check_page_elements() throws Exception {

    page.checkPageElementsExist();
  }
}

Page Class

public class SomeWebPage extends PageObject {

  @FindBy(id = "someID")
  private WebElementFacade someElement;

  @FindBy(linkText = "some text")
  private WebElementFacade someLink;

  @FindBy(className = "some-class")
  private WebElementFacade anotherElement;


  public void checkPageElementsExist() throws Exception {

    Field[] allFields = getClass().getDeclaredFields();
    for (Field field : allFields) {

      if (field.get(this) instanceof WebElementFacade) {

        WebElementFacade f = (WebElementFacade) field.get(this);

        if (!f.isPresent()) {

          System.out.println("ElementNotFound: " + field.getName());
        } else {

          System.out.println("Found: " + field.getName());
        }
      }
    }
  }

}
