„Out of Process“

var casper = require('casper').create(); 
 
casper.test.begin('Teste Rezeptsuche', 2, function suite(test) { 
casper.start("http://api/v2/recipes", function() { 
test.assertHttpStatus(200); 
test.assertEquals(10, JSON.parse(this.getPageContent()).results.length); 
}); 
casper.run(function() { 
test.done(); 
}); 
});

Feature: Admin Integration 
Als Salesmitarbeiter möchte ich das Wettbewerbsbackend 
über den normalen Admin verwenden können 
 
@mink:selenium2 
Scenario: Login über Admin 
Given A sales user "admin" with password "tester" 
Given I am on "https://admin-local/rezeptwettbewerbe/admin" 
Then I should see "Benutzername:" 
When I fill in "Benutzername:" with "admin" 
When I fill in "Passwort:" with "tester" 
When I press "Einloggen!" 
Then I should see "Liste der Rezeptwettbewerbe" 
And I should see "Logout" 
And I should see "Hallo admin!"
