BEHAT Behavior-driven development

Installing ■ Install Behat and Mink: composer require behat/behat/mink-extension laracasts/behat-laravel-extension --dev alias behat='~/behat/vendor/behat/bin/behat' ■ Let’s make auth so we can demo a login page check php artisan make: auth ■ Create features directory: behat --init ■ See the definitions list: behat -dl

■ In Feature. Context. php import Mink. Context: use BehatMink. ExtensionContextMink. Context; extends Mink. Context

So what is Mink? ■ The Mink Context simulates a web browser ■ Gives you functions like i. Am. On. Home. Page(), visit(page), press. Button(button), fill. Field(field, value)

Behat config Create behat. yml and. env. behat for behat specific variables behat. yml default: extensions: LaracastsBehat: env_path: . env. behat BehatMink. Extension: default_session: laravel: ~. env. behat APP_ENV=acceptance APP_DEBUG=true DB_PATH=acceptance. sqlite

Let’s write some Behat! Create example. feature Feature: Testing In order to teach Behat As a teacher I want to demonstrate how to install and create features Scenario: Home Page Given I am on the homepage Then I should see "forge" Scenario: Dashboard is locked to guests When I go to "home" Then the URL should match "login"

Is it not working Josh? Use a gif to distract everyone and make the font really small so it’s not embarrassing when your demo didn’t work and you forgot why… Edit your. env to use localhost: 8888 then run php artisan config: cache and then when that breaks your whole site do php artisan config: clear because pugs

Another example: authentication Create authentication. feature Feature: Authentication Why (To give registered members exclusive content) Who (As an administrator) What (I need authentication and registration for users) Scenario: Registration When I register "Josh. La. Mar" "jolamar@iu. edu" Then I should have an account behat --append-snippets
