Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to mock database calls
I'm the author of https://github.com/go-testfixtures/testfixtures, a library written to make it easier to write tests with a real database and test data. You might want to use it together with docker-compose, for example.
-
Integration tests with Go and testcontainers
To solve the problem we will use testfixtures. Create a folders fixtures и fixtures/storage and put a file users.yaml inside:
-
Mocking database or use a test database
A lot of good suggestions here, I would also take a look at go-testfixtures which allows you to create some simple yaml-based fixture data to use with unit testing. It's quick and easy, but yes can get unwieldy the more you add.

Ask HN: What are some tools / libraries you built yourself?
I built an alternative to Make written in Go that is simpler to use and cross-platform: https://taskfile.dev/
Also, a library to write tests with databases for Go: https://github.com/go-testfixtures/testfixtures

- How do you unit-test code that reaches out to the db, without introducing interfaces everywhere?
-
Creating an API using Go and sqlc
For that, I used the lib go-sqlmock. So, for example, the following snippet is part of the person/service_test.go file:
-
Using SQLC in project how do I mock database Calls with it for unit testing?
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.

Can you set expectations for SQL transaction using Testify?
I use Sqlmock for that purpose
- Mocking database queries - ask for opinion
- SQL mock driver for Golang to test database interactions
- Can't get a specifc SQL query with pgx to work
