Overview

mock

📡 mock is a simple, cross-platform, cli app to simulate HTTP-based APIs.

About mock

Mock allows you to spin up a local http server based of a .mock.yaml file. Preferably mock is used per project and a .mock.yaml file is created at the root of a repository.

Installation

Binaries

If you prefer grabbing mock its binaries, download the latest from the the GitHub releases page.

Brew

❯ brew tap bschaatsbergen/mock
❯ brew install mock

Chocolatey (Not supported yet)

❯ choco install mock

Usage

Running mock is very easy, by simply running the below command you tell mock to translate the .mock.yaml in the current working directory to an http server that by default runs under port 7070. Use the -p flag to change the default port.

❯ mock serve

📝 using config file: .mock.yaml
📡 starting mock on :7070, exit to stop

To bring you up to speed, we allow you to run the below command in order to generate an exampe .mock.yaml in the current working directory.

❯ mock init

🎉 generated '.mock.yaml' in: /home/bruno/Projects/MyNewApi

The generated .mock.yaml configuration looks as following. It's made up of a list of endpoints, each containing a resource path, http method, response and http status code.

# Example .mock.yaml config
Endpoints:
  - Resource: /city/1
    Method: GET
    Response: '{ "Id": 1, "Name": "Albuquerque", "Population": 559.374, "State": "New Mexico" }'
    StatusCode: 200

  - Resource: /city
    Method: POST
    Response: '{ "Name": "Albuquerque", "Population": 559.374, "State": "New Mexico" }'
    statusCode: 200

  - Resource: /city/1
    Method: PUT
    Response: '{ "Id": 1, "Name": "Albuquerque", "Population": 601.255, "State": "New Mexico" }'
    StatusCode: 200

  - Resource: /city/1
    Method: DELETE
    StatusCode: 204

After running mock serve you can verify whether the routes are available

❯ curl -i -X GET 'http://localhost:7070/city/1'
HTTP/1.1 200 OK
