Activity 10.01: Writing Tests for the Coffee-Ordering Application

Solution:

1. Import the testing namespaces:

   (ns coffee-app.utils-test
       (:require [clojure.test :refer :all]
                 [coffee-app.core :refer [price-menu]]
                 [coffee-app.utils :refer :all]))

2. Create tests using the clojure.test library to display the orders messages.
3. Test the application using the is macro:

   (deftest display-order-test
            (testing "Multiple tests with is macro"
                     (is (= (display-order {:number 4 :price 3.8 :type :latte}) "Bought 4 cups of latte for €3.8"))
               ...
