Dependency injection is very commonly used in the Go ecosystem. Do not confuse resistance about unidiomatic DI frameworks with resistance about DI itself.

  Which ones are common? I've been hoping this would be the case, but I've been unable to find evidence for it. e.g. the most-popular one I can see so far is Facebook's "inject", which has a remarkably small 841 stars: https://github.com/facebookgo/inject https://github.com/facebookgo/inject Even Glide, Godep, and Dep have several thousand. And those can barely claim "most", much less "very common".

    What do you mean which ones? I am talking about dependency injection as a technique/pattern. In Go you can just do it without importing anything. Please read: https://medium.com/@benbjohnson/standard-package-layout-7cdbc8391fc1#db5a https://medium.com/@benbjohnson/standard-package-layout-7cdb... (I've linked to the exact point in the article where it talks about DI but you might want to read the rest as well.)

      Yeah, it's widespread as a hand-coded thing. It has to be - you essentially have no choice in Go for even basic things like tests. But that just means that everyone rolls their own thing by hand, with widely-varying feature-sets, method names, bugs, etc. DI frameworks are very much nicer for interop between a bunch of libs.
