social VS go-sqlmock

Here’s a semi in depth go walk through building a sample project from scratch: https://github.com/imran31415/social/blob/main/blog/BLOG.md

This one https://github.com/imran31415/social

I made a write up on using go with VUE and go into some detail https://github.com/imran31415/social/blob/main/blog/BLOG.md

Example: https://github.com/imran31415/social/blob/main/blog/BLOG.md

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
