Geb Page objects methods not accessible in cucumber steps implementation - groovy

Question

I am able to read the text of an element on a web page through my cucumber steps file but when I want to move that method to Page Object file then system throws an error.
The framework used: Groovy, Geb, Cucumber, Gradle
Steps file
com.checkout.automation.buy.stepdefs
import com.buyautomation.pages.CartPage
import com.buyautomation.pages.common.CookieTrait
import com.checkout.automation.services.Util
import com.expectedData.CartPageExpectedData
import cucumber.api.java.en.Given
import cucumber.api.java.en.Then
import cucumber.api.java.en.When
class CartSteps extends GebCuke implements CookieTrait {
private Util util
CartSteps(Util util) {
this.util = util
}
#Then("I am notified that my cart is empty")
def emptyCartNotificationCheck() {
if (CIASteps.user == "Guest User") {
at CartPage
// This does not work
assert getEmptyCartText()== CartPageExpectedData.expectedText.emptyCartGuestUserHeading + CartPageExpectedData.expectedText.emptyCartGuestUserSubText
//This works
assert $("div.empty-cart__info").text() == CartPageExpectedData.expectedText.emptyCartGuestUserHeading + CartPageExpectedData.expectedText.emptyCartGuestUserSubText
}
else {
assert $("div.empty-cart__info").text() == CartPageExpectedData.expectedText.emptyCartRegisteredUserHeading + CartPageExpectedData.expectedText.emptyCartRegisteredUserText
}
}
}
Page Object File. I want to store the element locator and functions which deal with elements in this file
package com.buyautomation.pages
import geb.Page
class CartPage extends Page {
static at = { assert title == "Cart" }
static content = {
emptyCart(wait:true) {$("div", class:"empty-cart__info")}
itemQuantity(wait:true) {$("div", class:"cart-item__quantity-block")}
}
def getEmptyCartText() {
emptyCart.text()
}
Error: When using method to get the text using page object function then I get the below error. However , If I refer to element directly in the step file then the code works
groovy.lang.MissingPropertyException: Unable to resolve itemQuantity as content for geb.Page, or as a property on its Navigator context. Is itemQuantity a class you forgot to import?

Answer 1

Try prefix the method call with the page object class CartPage:
assert CartPage.getEmptyCartText()== CartPageExpectedData.expectedText.emptyCartGuestUserHeading + CartPageExpectedData.expectedText.emptyCartGuestUserSubText
Although your error is stating that it can't find itemQuantity which is being called in your When step:
When I update the quantity to exceed the maximum limit(cartMessages.feature:33)
Make sure you use CartPage.itemQuantity when referencing it.
And import the CartPage within your test:
import com.buyautomation.pages.CartPage
