    I then verify that there are no issues with writing the body with require.NoError() from the testify toolkit. This will ensure the test fails if something happens to go wrong at this point.

    For testing purposes, Go provides a go test command that automatically discovers tests within your application and supports features such as caching and code coverage. However, if you require more advanced testing capabilities such as suites or mocking, you will need to install a toolkit like testify. Overall, while Go provides a highly effective testing experience, it's worth noting that writing tests in Python using pytest is arguably one of the most enjoyable testing experiences I have encountered across all programming languages.

    Things I can't live without in a new Go project in no particular order:

    - - meta-linter

    - - automate release workflows

    - - build tool that can version your tools

    - - run containers for e2e testing

    - - generate functional options

    - - generate String()

    - - stricter gofmt

    - - test assertion library

    - - logging

    - - CLI framework

    FWIW, I just lifted all the tools we use for

    We've also written some custom linters that might be useful for other folks:

    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

    FWIW, I've been using testify and mockery for years.

    To answer OP directly, I am largely quite happy with mockery (and testify) to write expressive tests.

    Best tool in the ecosystem testify. Learn about Table driven test, suite - saves your time so much with setup & teardown. Absolutely one thing you need to follow, if you see anything breaking (or bugs) add tests for that, could be unit tests or integration tests, this's of huge value and reduces manual testsing.
