Feature: Output nginx configuration file

  In order to run my application as an nginx virtualhost
  As a user of the library
  I want to output a nginx virtualhost configuration.

  Scenario: using command-line options
    When I run `bundle exec vhost-generator -g nginx -o upstream=myupstream -f html -l 80,81 -s localhost,my.server -p 5000,5001,5002 -r /myapp`
    Then the output should match /FILE GENERATED BY.*EDIT AT YOUR OWN RISK/
    And the output should contain:
      """
      upstream myupstream {
        server localhost:5000 fail_timeout=0;
        server localhost:5001 fail_timeout=0;
        server localhost:5002 fail_timeout=0;
      }
      """
    And the output should contain:
      """
      server {
        listen 80;
        listen 81;
      """
    And the output should contain:
      """
        server_name localhost, my.server;
      """
    And the output should match /root.*html;/
    And the output should contain:
      """
        try_files $uri/index.html $uri @upstream;
        location @upstream {

        }
      """
      And the output should contain:

        }
      """
      And the output should contain:

  Scenario: using environment variables
    When I set env variable "GENERATOR" to "nginx"
    And I set env variable "GENERATOR_OPTIONS" to "upstream=myupstream"
    And I set env variable "STATIC_FOLDER" to "html"
    And I set env variable "SERVER_PORTS" to "80,81"
    And I set env variable "SERVER_NAMES" to "localhost,my.server"
    And I set env variable "INSTANCE_PORTS" to "5000,5001,5002"
    And I set env variable "RAILS_RELATIVE_URL_ROOT" to "/myapp"
    And I run `bundle exec vhost-generator`
    Then the output should match /FILE GENERATED BY.*EDIT AT YOUR OWN RISK/
    And the output should contain:
