hoverfly VS mockhttp

Use https://github.com/SpectoLabs/hoverfly

Hoverfly is an open-source tool for mocking and simulating APIs. It is relatively easy to use and has a wide range of features for mocking and simulating APIs, including support for importing and exporting mock configurations, generating random data for responses, and setting up conditional responses based on the contents of incoming requests.

Depending how robust their check in is, you could intercept and emulate the reply with something like hoverfly too.

What is your recommendation? Is there one widely used in the Golang community? I have come across hoverfly, but I wanted to have a few to perform a good benchmark exercise. Thanks

I'd say that without wanting to refactor the code a little bit (maybe moving those HttpClients into a service so that they are easily mocked) your best bet would be to use something like WireMock or MockHttp.

What is the need to create a wrapper around the HttpClient? If it's for mocking, you can use this MockedHttpClientHandler for you tests

Voilà! That's how to write tests with HttpClient and Moq. With some extension methods, we could have a small DSL to write more readable tests. For a more fully-featured alternative to write tests for HttpClient, check mockhttp, "a testing layer for Microsoft's HttpClient library."

So if you need to mock http client you may want to look into a library like https://github.com/richardszalay/mockhttp
