hoverfly VS go-sqlmock

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

For that, I used the lib go-sqlmock. So, for example, the following snippet is part of the person/service_test.go file:

It's not the right call IMO to skip mocking the database connection to achieve 100% test coverage. How your app will behave in failure scenarios that are impossible to imitate during integration tests is part of the software contract. If your choice is to panic, or return an error, document that by testing that behavior. If another dev, or future you inadvertently breaks the contract, the test suite will fail. That's what you want. For unit tests against your database you should be using either go-sqlmock if testing against database/sql or pgxmock if testing against pgx. That being said, the points raised elsewhere in this thread regarding unit tests potentially hiding edge cases in terms of how an actual database will interact with your application that are not reflective of your understanding when writing mocks are 100% valid. You should do both. Unit test your app and write integration tests as well. On my team, we run integration tests using docker-compose.

I use Sqlmock for that purpose

There is a good lib for db tests https://github.com/DATA-DOG/go-sqlmock
