However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.
This article reveals how to integrate WireMock into Fastify with ease, enabling developers to effortlessly generate mock responses for external services. Join us as we explore the straightforward process of seamlessly integrating and optimizing Fastify applications using WireMock for enhanced testing capabilities.
Mockoon - Used as a logging server instead of using print in the console.
I'm far too lazy to write mocks by hand in go. You can generate a mock for a given interface with mockery https://github.com/vektra/mockery
Since the OpenAPI can effectively describe our resources, we can reuse it to generate a dummy server that can be later used for development and testing purposes without bootstrapping any actual services. There some tools available that can help us with this task, such as Prism, OpenAPI Mock, OpenAPI Backend and the MSW library we have already seen.
Pester is what's used for most Powershell testing. While it has some pretty amazing features, it does have issues with .NET class method mocking and sometimes scope can be weird. Here's a simple example:
I made a library for this: https://github.com/kevin1024/vcrpy
a. you might do so purely out of argo cult, i.e. because someone told you this was the right thing to do™, and that's a silly exercise. b. you could also be doing this for a good reason: to use the interface with a mocking tool like NSubstitute
Project mention: vektra/mockery has fully released the "packages" feature! This blog explains what it is and how it works. | /r/golang | 2023-07-11
Swift testing this simple Hello World with XCTest and Cuckoo
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.
