mockery VS moq

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).

Moq’s prior version, 4.18.4, free of the exfiltration behavior, accounts for 6,765,006 downloads in the past six weeks, demonstrating the potential blast radius of privacy breach if a developer hadn’t noticed the issue and raised it with the community.

NSubstitute is good, I used it at a previous job.

I've favored Moq in the past because I think there are a couple of things it makes a bit easier or is a bit less opinionated about, but NSub is perfectly cromulent as well.

Someone posted a quick guide to migrating a bunch of it easily in one of the issues in the Moq repo discussing this whole mess: https://github.com/moq/moq/issues/1374#issuecomment-16712411...

Moq was is a popular .NET mocking library that has accumulated over 475.7 million downloads as of now.

Just don't update to 4.20 until https://github.com/moq/moq/pull/1373 resolved

Maintainer rejected the PR. They have temporarily disabled the integration in https://github.com/moq/moq/pull/1375 but kept the SponsorLink project reference in the source code. It seems like their intent is to re-enable the integration at a later point :(

NSubstitute [0] might be an alternative. Or to fork Moq pre-4.20.

Today I want to cover some simple testing setup and configuration. I'll be using my example project from the Dapper & CQRS post I made last week so consider this post a part 2. For tooling I'll be using xUnit and Moq as well as a few other nuget packages to easily configure and run tests in Visual Studio. I am working on a Mac, but operating system shouldn't matter.

Nota: Por muito tempo utilizei uma outra biblioteca chamada Moq que faz a mesma coisa porém com sintaxe diferente. Ultimamente tenho dado preferência pelo NSubstitute exatamente por parecer legível.
