Overview

Do you ever have experience about needing to set up a very simple application and write some APIs with hardcode response again and again for developing Font-End site? PyFake-API-Server provides a command line tool to let developers could quickly and easily set up application to mock APIs with configuration only.

Python versions support

The code base of PyFake-API-Server to set up an application still depends on third party Python package, i.e., Flask, FastAPI, etc. So the Python versions it supports also be affected by them, e.g., Flask only supports Python version 3.9 up currently. So PyFake-API-Server also only supports version Python 3.9 up.

Quickly Start

Here section would lead you quickly start to set up your first one application by PyFake-API-Server for mocking API server easily.

In basically, it has 3 steps: install the package, configure settings about the APIs for mocking and run command.

• Install
• Configure
• Run

Install command line tool

First of all, we need to install the command line tool and the way to install is same as installing Python package by pip.

>>> pip install fake-api-server

If the runtime environment has installed some Python web framework, e.g., Flask, you also could install PyFake-API-Server with one specific option as following:

>>> pip install "fake-api-server[flask]"

Then it would only install the lowest Python dependencies you need.

After you done above step, please make sure the command line tool feature should work finely by below command:

>>> fake --help

Note

Please take a look at option --app-type (this option is in subcommand mock run) of the command line tool. Its option value could be auto, flask or fastapi. It means that PyFake-API-Server only supports 2 Python web frameworks: Flask and FastAPI.

Configure setting to mock target APIs

Now, we have the command line tool. Let's configure the settings it needs to set up application to mock API.

The configuration format of PyFake-API-Server to use is YAML. So let's write below settings in YAML file:

mocked_apis:
  foo:
    url: '/foo'
    http:
      request:
        method: 'GET'
      response:
        strategy: string
        value: 'This is Foo API.'

Run command to set up application

Now, both of the command line tool and configuration have been already. So let's try to run the command to set up application!

>>> fake rest-server run -c <your configuration path>

You would see some log messages in terminal and that is the log of web server by one specific Python web framework.

And you could test the API by curl:

>>> curl http://127.0.0.1:9672/foo
"This is Foo home API."%
