go-sqlmock VS snapcraft

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

Hopping from one distro to another with a different package manager might require some time to adapt. Using a package manager that can be installed on most distro is one way to help you get to work faster. Flatpak is one of them; other alternative are Snap, Nix or Homebrew. Flatpak is a good starter, and if you have a bunch of free time, I suggest trying Nix.

My personal favourite IDE for java is Intellej Idea. Apart from not demanding the extra extension, It was designed special for Java and Java related languages so it runs java smoothly with great compilation time. so lets install it. Make sure you have snap before installing it

Linux Mints App Store is full of GUI programs, Snap Store ist full of it, Flathub is full of it.

You are being lazy. But I recommend bringing your ass directly to snapcraft.io and reading those documents in the Learn section!!

https://github.com/snapcore/snapcraft - not sure, but looks like a building tools for snaps

Besides, there may be other ways to install them, although there doesn't seem no such Flatpak packages in Flathub. For example, some senerio to use some release channel or Docker / Podman. Additionally, when you use a different Linux distro where systemd is adopted and therefore can do Snaps (Snapd), you have another possibility.

Devuan GNU+Linux is a fork of Debian without systemd and hence Snaps (Snapd). Even on it, it's easy to install Android Studio and start to develop Android mobile apps.
