Easy Http mock

The goal of this project is to provide a simple way to mock http request and response for specific condition.

1. Install

    gem install easy-http-mock
   

2. Create a yaml file to config the mocked services,

   #settings.yml
   ---
     - 
   	request: 
         	path: /bar
   	response: bar.json
     -
   	request:
         path: /bar
   	  query:
       	param_one: haha
           param_two: blabla
   	response: bar_haha.json
   ...
   

3. Start mocking server

    ehm settings.yml
   

4. Test the results

    curl http://localhost:4567/bar
   

   You will get the text that specified in bar.json. As we have defined in the settings.yml, when visit /bar, it will return the bar.json file.

    curl http://localhost:4567/bar?param_one=haha&param_two=blabla
   

   You will get the text that defined in bar_haha.json. So the second route definition will only be return when you request it with specified params with the correct value.

    curl http://localhost:4567/bar?param_one=not_correct_value
   

   This one will return the bar.json, since if any of the conditional definitions(The second one) are not satified, then the default one(The first one in this example) will be returned.

Create your settings file with yaml node anchor and reference

---
  - &bar
    request: &bar_request
      path: /bar
    response: bar.json
  -
    request:
      <<: *bar_request
      query:
        param_one: haha
        param_two: blabla
    response: bar_haha.json
  -
    request:
      <<: *bar_request
      query:
        param_three: hehe
    response: bar_hehe.json
...

With this, you can reuse other mock service defination. For example, all the three service in the settings.yml using same path, so we can use yaml anchor and reference to reduce the redundant settings.

Using following command to show help information, you can config the port and bind address for the server.

ehm -h

Other http verb, for example POST, PUT and DELETE will be added.
