  • 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?

    I’m writing a post about it! I will post soon, but you can use https://github.com/DATA-DOG/go-sqlmock to mock your database calls
    3 projects | /r/golang | 22 Oct 2022
    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 https://github.com/DATA-DOG/go-sqlmock for unit testing my data layer code. Most of the times, these tests help me to find errors whenever I do a refactor on the data layer, so I consider it a good safety net

    For testing DB queries I use https://github.com/DATA-DOG/go-sqlmock for unit tests. I then have a separate integration test suite that runs against all our services using Docker.

  • Tools besides Go for a newbie
    36 projects | /r/golang | 26 Mar 2023
    IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here
  • When to mock and what to mock in a Web API?

    Normally I like to generate everything with Mockgen and test it using table driven test.
  • Is gomock still maintained and recommended?
    7 projects | /r/golang | 6 Mar 2023
    Looking at gomock's commit history, it seems like there hasn't been much activity on the project in a couple of years. I'm wondering if this is the case of software being mostly done and just in maintenance mode, or if gomock is falling behind. The reason I fear for the latter is there are still issues being opened up that don't seem to be engaged very much.
  • Want to know if this is a valid approach
    2 projects | /r/golang | 2 Mar 2023
    Yeah, that would work just fine. Nevertheless, as your business logic gets more complicated, you will want to test more scenarios and mocks will get complicated fast. In these cases tools like gomock really shine and make your life easier. I understand that this is a just-for-fun project, but it's never too early to experiment with a popular solution, especially if you plan on using Go professionally in the future.
  • Go API Project Set-Up

    Unit tests are leveraged to test individual units of code. As such it is not recommended for a developer to scaffold entire dependencies for the sake of testing a single object. Due to the way Go's specific implementations work, I've learned over time to declare interfaces for a lot of the structs that I use in Go. Interfaces not only define a contract for which struct-based implementations should adhere, but they also provide a mechanism for which struct methods can be mocked. While I've experimented with the mock package in testify, I've come to prefer the mock functionality which is provided by mockgen.

    I use gomock or mockery for mocking the interfaces and testify for evaluating tests
