httpmock VS go-vcr

We will use httpmock for this purpose. Inside function setupSuite(), where we created useCase and provided nil as a billingClient now we will pass mocked http client:

Alternatively, you could use an http mock library like https://github.com/jarcoal/httpmock, and override the urls the RealClient calls with a mock response in your tests.

To mock an API: https://github.com/jarcoal/httpmock to use when your code calls external APIs so you don't want your tests call the real API. No need to create an interface as you do.

Mocking the http client using recorded responses; for example using dnaeon/go-vcr

For example I see go-vcr (note: not mine), but haven't taken time yet to evaluate it.

I've finally found some spare time and managed to work on go-vcr, fixed some long standing issues, refactored things here and there and was able to get a new version of the package.

Terraform providers are tested this way (separate cloud account w/ create/destroy) paired with VCR to record and replay the HTTP requests.

Let me introduce to you github.com/dnaeon/go-vcr.
