counterfeiter VS go-testdeep

then just replace whole function, don't generate manually the mock '__') or it would get out of hand fast, you can just use codegen that static typed like https://github.com/maxbrunsfeld/counterfeiter

Yes, that's a good way to do that; there are a lot of packages that allow you to mock and spy the calls if you're looking for one that generates the code for you I can recommend counterfeiter, I also have a short blog that covers it.

I prefer https://github.com/maxbrunsfeld/counterfeiter

counterfeiter is another tool, it creates mocks, stubs and spies; here is a short blog I wrote covering it.

for dependency injection I suggest you use https://github.com/maxbrunsfeld/counterfeiter, but if you using really fast database (that can spawn fast using docker and has fast trx/sec) you can use it directly without dependency injection with https://github.com/ory/dockertest

Agree with u/mmknightx there is a tool that assist in creating fake or mock classes for your interfaces https://github.com/maxbrunsfeld/counterfeiter

Another alternative to use would be counterfeiter, it generates a type from your interface that could be used as a mock, stub or spy. I wrote a short post covering that tool if you're interested.

And do not forget to use go-testdeep and its JSON operator to test JSON content: :)

TestDeep. I got pretty used to many of the matchers and they simplify my life now.

To see the result on a large repository, I adapted the comments of go-testdeep to fully take advantage of these new features.

Check also go-testdeep → https://goplay.tools/snippet/KgoeGR1bIwT the full featured testing framework... (not related to go-test/deep)

Check go-testdeep using its operators, it is very easy to do table driven tests, see https://goplay.space/#Z91D72aH3Sc for an example

See https://github.com/maxatome/go-testdeep/releases/tag/v1.11.0 for changes.

the 1.10.0 release with many new features including a new SuperSliceOf operator (so now 62 operators!), a relaxed JSON parser, the possibility to ignore unexported struct fields, to target a specific nested field (even private), the enhancement of tdhttp HTTP API tester to check cookies, to use multipart/form-data bodies, and many other magic things…

And of course go-testdeep which colorizes the error reports with simple but accurate diff.
