Personally I preffer to use minitest and use dependency injection rather than the magic "allow to_receive and_return" parts of rspec. This makes my code more reusable.

But don't get me wrong, I won't refuse using rspec if it's already set up for a project, just wish it wasn't the go to default. I do believe the ruby + rails code people write would be better architected and more reusable with minitest + D.I. rather than rspec.

I could never warm to MiniTest, even though I want to as it's in the standard lib and I dislike unnecessary dependencies.

I've not checked recently but last time I used it didn't provide colour output without plugins and didn't include verifying doubles or spies out of the box.

There were a lot of other decisions required to make Minitest plesant in non-rails projects.

You can still use dependency injection with Rspec, it's just a nicer experience IMHO.
