mockery VS gomock

Some of the features: - ✅ Using Vertical Slice Architecture as a high level architecture - ✅ Using Event Driven Architecture on top of RabbitMQ Message Broker with a custom [Event Bus](pkg/messaging/bus/) - ✅ Using Event Sourcing in Audit Based services like [Orders Service](services/orders/) - ✅ Using CQRS Pattern and Mediator Patternon top of Go-MediatR library - ✅ Using Dependency Injection and Inversion of Controlon top of uber-go/fx library - ✅ Using RESTFul api with Echo framework and using swagger with swaggo/swag library - ✅ Using Postgres and EventStoreDB to write databases with fully supports transactions(ACID) - ✅ Using MongoDB and Elastic Search for read databases (NOSQL) - ✅ Using OpenTelemetry for collection Distributed Tracing with using Jaeger and Zipkin - ✅ Using OpenTelemetry for collection Metrics with using Prometheus and Grafana - ✅ Using Unit Test for testing small units with mocking dependent classes and using Mockery for mocking dependencies - ✅ Using End2End Test and Integration Test for testing features with all of their real dependeinces using docker containers (cleanup tests) and testcontainers-go library

There are some one liner changes you can implement in https://github.com/vektra/mockery

When there's just one heavyweight dependency you're interacting with, perhaps a one-off stub/fake is simpler, but I would posit that auto-generated mocks via things like mockery + go:generate leave less test code to maintain vs. perhaps many stubs across the project.

My bread and butter is mockery (https://github.com/vektra/mockery). It has a few shortcomings (a config would be really nice in my project) which should be fixed in v3 (https://github.com/vektra/mockery#v3).

One of the huge benefits to this pattern is testability. Since each layer is injected into each parent layer, we can generate mocks for each layer and inject those instead. For this code we could easily achieve 100% code coverage when unit testing each layer, since we have full control of the child layers. A great tool to use for generating mocks from interfaces is vektra/mokery. One command will create mocks for each of your interfaces that we can inject during test.

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

Since mockery uses a lot of interface{} magic, adding arguments or return values to interfaces and regenerating the mocks does not get the compiler to complain about existing, now invalid, usages of the mocks. This means that I have to track them down manually. Or, if I'm brave enough, try my hand at a few crazy regexes that never get the job 100% done.

go-mocky does not use interface{}s, and thus can't hide changes to function signatures from the compiler; whenever a mock has been updated and the function signature has changed, the compiler will complain for all existing tests. This means that I can now catch errors at compile/lint time instead of runtime.

Another added benefit is that the go-mocky mocks are dead simple and very easy to write and maintain by hand, should the need ever arise.

+1 on testify. Started out with that, and it, together with its mocks and the framework mockery are a brilliant combination, assuming you are into testing with mocks to some extent

I use mockery to generate mocks based on my interfaces: https://github.com/vektra/mockery

There are some packages in my project that are not used in the source code, but they're used as commands (i.e. https://github.com/vektra/mockery https://github.com/rubenv/sql-migrate).

The commit mentions this rather sad thread: https://github.com/golang/mock/pull/627#issuecomment-1605169...

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

Normally I like to generate everything with Mockgen and test it using table driven test.

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.

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.

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.

Where we do use mocks, we primarily use GoMock.

Currently migrating from moq to https://github.com/golang/mock
