A Tiny HTTP Server for Testing HTTP Clients

Given a configuration file describing routes and actions, mock-httpd will bind to the specified ports and respond to incoming HTTP requests.

The primary goal of this project is to provide a simple way to test shell scripts that use curl.

Configuration

A YAML configuration file is used to control mock-httpd. The file is split between general configuration and routing information.

General Configuration

The following settings control all requests:

• listen: An array of directives, each of which causes mock-httpd to bind to a port and listen for requests.

  Example:

  listen:
    - port: 3210
  

• directory: A path to a directory where files can be read from and written to. All routing actions involving files are restricted to this directory.

An [example configuration](example.yml) is included with the distribution.

Routing Information

The routing section of the configuration file is used to match incoming requests and perform corresponding actions.

Example:

routes:
  - match_path: /hello
    match_method: GET
    actions:
      - serve_text: "Hello World!\n"
      - content_type: text/plain

Route Matching

Match directives (properties starting with match_) are used to select actions to perform for incoming requests. All listed match directives must match the incoming request in order for the containing route's actions to be performed. Only the first matching route is used.

• match_path: Exact string comparison with the requested path.

• match_method: Exact string comparison with the request method.

Actions

The following actions can be taken when a route matches:

• serve_file: path: Send the specified file back to the client.

• serve_text: text: Send arbitrary text back to the client.

• location: url: Set the Location header.

• content_type: type: Set the Content-Type header.

• set_headers: hash: Set each entry in the specified hash as a response header.

• response_code: code: Set the response code to code.

• save_body: path: Write the request body to the specified file.

NOTE: The serve_* actions are mutually exclusive and only the first one will be used. If no serve_* action is specified the default action is to respond with an empty body.
