Golang gorm mocking

Question

I am using gorm in my projects. Can I mock this database orm for testing without database connection? The problem we have CI tools where I don't have database or database with enough data for testing. The other way, I don't want to setup a database for every time I'm testing, because in these cases the CI tool create every time a container just for run the tests.

Whet is the best way for testing database related methods? I am using dependency injection in my solutions so it is easy to replace the database with a mocked database. But the gorm have many orm related function.

This is a handler for example:

func tokenIntrospectionHandler(db *gorm.DB) http.HandlerFunc {
    return http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) {
        defer req.Body.Close()
        token := req.FormValue("token")
        var resp Response
        json.NewEncoder(w).Encode(resp)
    })
}
