The document outlines the structure for behavior-driven development (BDD) tests, including a user story describing a feature to send messages between users with shared habits. It provides an example scenario for this user story and models the domain with classes for users, habits, chats, and messages. An example test is given to validate that both users receive a message sent between them in the same chat.

- 2. User Story As a [Role] I want [Feature] So that I receive [Value]
- 3. Scenario: how? Given [State] When [Action] Then [Reaction]
- 4. Domain Model User – зарегистрированный пользователь Habit – привычка Message – сообщение от User к User Chat – место общения двух User
- 5. User Story: Send Message As a User I want to send Message to another User who forms the same Habit So that I receive motivation

- 7. Example public void bothUsersShouldRecieveMessagesFromEachOther () { User sender = new User(); User recipient = new User(); Chat chat = new Chat(sender, recipient); given(sender.hasHabit(“Refactoring”)); given(recipient.hasHabit(“Refactoring”)); chat.sendMessage("Aloha!"); then(chat.hasMessage(“Aloha!”)); }
- 8. + sendMessage(User who, User whom, String message) + getChat(User, User) – Map<Chat> chats (key: username1+username2, val: Chat) ChatManager + sendMessage(User whoSent, String message) + List<Message> getMessages() – List<Message> messages Chat + Message(User user, String message) + getUser() + getMessage() – User user – String message Message – String username – List<Habit> User – String name Habit <<sendMessage>> <<creates>> <<creates>> Chat with «whom.name» Message.user: message Message.user: message Message.user: message
