API simulations for development and testing

Hoverfly is a lightweight, open source API simulation tool. Using Hoverfly, you can create realistic simulations of the APIs your application depends on.

• Replace slow, flaky API dependencies with realistic, re-usable simulations
• Simulate network latency, random failures or rate limits to test edge-cases
• Extend and customize with any programming language
• Export, share, edit and import API simulations
• CLI and native language bindings for Java
• REST API
• Lightweight, high-performance, run anywhere
• Apache 2 license

Hoverfly is developed and maintained by SpectoLabs.

Setup for local development

Build

1. Install Go. You should follow the download and installation instructions for your OS from official Go website. If you have installed Go before using either apt-get or homebrew, you should uninstall those first.

2. After the installation, find out the GOPATH using go env, and then setup a source folder there

   mkdir $GOPATH/src

3. Clone the hoverfly project into your Go source folder:

   cd $GOPATH/src
   mkdir -p github.com/SpectoLabs/
   cd github.com/SpectoLabs/
   git clone https://github.com/SpectoLabs/hoverfly.git
   # or: git clone https://github.com/<your_username>/hoverfly.git

4. Finally you can run the build

   cd hoverfly
   make build 

Notice the binaries are in the target directory.

Test

You should be able to execute all unit and functional tests with:

make test

Some middleware tests may fail if you don't have ruby and python setup in your environment. If you are using Mac, you can install them with Homebrew:

brew install ruby
brew install python
