Test case for Valid Coupon Code

This test case checks whether a valid coupon code is successfully applied to a booking cart, the total is updated accordingly, and a success message is displayed.

package com.seleniumExamples2024;

public class BookingCart {
	private double total;
    private String confirmationMessage;

    public void addItem(String itemName, double itemPrice) {
        // Simulated logic to add an item to the cart
        // For simplicity, the item price is directly added to the total
        total += itemPrice;
    }

    public boolean applyCoupon(String couponCode) {
        // Simulated logic to apply a coupon
        if ("VALIDCODE123".equals(couponCode)) {
       // For simplicity, assuming the coupon provides a 10% discount
            total *= 0.9;
            confirmationMessage = "Coupon applied successfully";
            return true;
        } else {
            confirmationMessage = "Invalid coupon code";
            return false;
        }
    }

    public double getTotal() {
        return total;
    }

    public String getConfirmationMessage() {
        return confirmationMessage;
    }

}
}
