Feature: Test a site with javascript included
As a software developer
I want to develop a site using javascript
I would like to have a server step rendering javascript correctly in order to test it

Scenario: Existing app with javascript
Given the Server is running at "javascript-app"
When I go to "/index.html"
Then I should see:
"""
Local Hour
"""
And I should see:
"""
Local Minutes
"""
