Rack::OverridePath overrides responses for web applications

Install the gem:

gem install rack-override-path

Or in your Gemfile:

gem 'rack-override-path'

require 'rack/override-path'
require 'webrick'

app = lambda do |_env|
[200, { 'Content-Type' => 'text/plain' }, ['Hello World']]
end

Rack::Handler::WEBrick.run Rack::OverridePath.new(app)

Specify a path, with one or more Override Parameters.

Subsequent requests matching path will be overridden.

POST /override/path
{
  "delay": 2,
  "headers": { "Content-Type": "text/plain" },
  "status": 404,
  "body": "Nothing found",
  "method": "GET",
  "path": "/index.html"
}

In the example above, GET requests for /index.html will respond with a 404 status with Nothing found in the body after a 2 second delay

The path can be literal (e.g /index.html) or a regular expression (e.g .*videos.*)

At least one Override Parameter must be included in each Configured Override

• body
• delay - should be an Integer value, in seconds
• headers
• status - should be an Integer value

Filters are optional

• method - acceptable values are GET,PUT, POST, PATCH, DELETE, HEAD, OPTIONS. If method parameter is not specified, all methods for the matching path are overridden

    {
        "delay": 2,

            "Content-Type": "text/plain"
        },
        "status": 404,
        "body": "Nothing found",
        "method": "GET",
