fakehub

fakehub - A fully functional fake version of a GitHub REST API that supports all the features and works locally, with no connection to GitHub at all.

Motivation. There are many applications that use GitHub API for different purposes. All of them need to create automated tests, which need to mock the API server somehow. We offer a fully functioning mock version of a GitHub REST API, which would support all functions, but work locally, with absolutely no connection to GitHub.

Quick start

First, install it from crate:

cargo install fakehub

Then, create a simple test, test.sh:

{
  fakehub start -d
  out="$(curl -s 'http://localhost:3000/users/jeff' | jq -r '.login')"
  expected="jeff"
  if [ "$out" == $expected ]; then
    echo "Test passed!"
  else
    echo "Login '$out' does not match with expected: '$expected'"
    exit 1
  fi
  fakehub stop
}

And run it:

sh test.sh

You should be able to see this:

2024-10-15T15:14:33.469924Z  INFO fakehub: Starting server on port 3000
2024-10-15T15:14:33.470238Z  INFO fakehub: Server is running in detached mode on port 3000

Overview

fakehub is a full clone of GitHub REST API. This is very beneficial for testing, when you should not use real GitHub, but a mock version of it instead. fakehub stores all the data in memory. When request arrives, we query the storage, transform objects into GitHub API-compatible format (JSON) and give it to you.

Request format

fakehub supports the format specified in GitHub REST API docs. For instance, if you want to use Get a repository endpoint: you should just replace api.github.com to localhost:$port (make sure that fakehub is running on specified port).

curl -L \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer <YOUR-TOKEN>" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  http://localhost:$port/repos/OWNER/REPO

Attention! Don't use your own GitHub Personal Access Tokens to authorize in fakehub. Instead, use generated token by fakehub:

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{"login": "jeff"}' \
  http://localhost:$port/login

This should generate you an access token to fakehub API.

GitHub objects

TBD..
