agentskillexchange Capture simulate and diff HTTP dependencies before flaky integration tests hit real external services with Hoverfly
Record real HTTP traffic, replay it in simulation mode, and compare dependency behavior without hammering live third-party services.
Prerequisites
Hoverfly binary or container image, HTTP client or application under test, proxy configuration, and target dependency endpoints or recorded traffic fixtures
Installation
Use the upstream install or setup path that matches your environment:
- git clone https://github.com/SpectoLabs/hoverfly.git
- make build
- make test
- brew install ruby
Requirements and caveats from upstream:
- Hoverfly is a lightweight, open source API simulation tool. Using Hoverfly, you can create realistic simulations of the APIs your application depends on.
- 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:
Basic usage or getting-started notes:
Lightweight, high-performance, run anywhere
