Feature: Addition
In order to avoid silly mistakes
As a math idiot
I want to be told the sum of two numbers
Scenario: Add two numbers
Given I have entered 10 into the calculator
And I have entered 5 into the calculator
When I press ‘plus’
Then the result should be 15

27. МИНУСЫ
1. Не все PHP-разработчики знают/хотят знать Ruby
2. Сложность при описании входных условий
3. Невозможность использования PHP библиотек
4. Скорость работы кросс-языкового решения
28.
29. 1. Написан с нуля на PHP5.3
2. Написан с применением Symfony Components
3. Старается быть Cucumber’ом с входными/выходными данными
4. Полностью нативное решение на PHP
5. Столь же быстр, что и Cucumber (проверено)
6. Поддерживает полную и17ю
7. Полностью расширяем и настраиваем
8. Поддерживает различные типы лоадеров
30. ФУНКЦИОНАЛ
Feature: Serve coffee
In order to earn money
Customers should be able to
buy coffee at all times
Scenario: Buy last coffee
Given there are 1 coffees left in the machine
And I have deposited 1$
When I press the coffee button
Then I should be served a coffee
35. ИСПОЛНЕНИЕ
Feature: Behat Console Runner
Scenario: Run feature from CLI
Given I have default Behat configuration
When I call ‘behat -f progress’
Then it should pass
<?php
$steps->Then(‘/^it should (fail|pass)$/’,
function($world, $status) {
...
}
);

<?php # ./user.php

{
public function __construct($username, $age = 1)
{
}
public function getName() {}
public function getAge() {}
}
42. FEATURE
# ./features/user.feature
# language: ru
Функционал: Базовый Пользователь
Чтобы работать с пользователями
Как разработчик сайта
Я хочу иметь доступ к
пользовательской модели
Сценарий: Создание пользователя
Допустим у нас нет пользователей
Если мы добавим пользователя ‘everzet’
То у нас должно быть 1 пользователей
И имя у первого пользователя ‘everzet’
46. РЕАЛИЗАЦИЯ
<?php # ./user.php
class User
{
protected $name, $age;
public function __construct($username, $age = 1)
{
$this->name = $username;
$this->age = $age;
}
public function getName() { return $this->name; }
public function getAge() { return $this->age; }
}
