How about “the mountain in the sea” by ray nayler? I actually have liked everything ive read by him. Not quite like anathem which really I should go back and reread- that book is fantastic

Maybe blindsight by peter watts?

This is a two for one deal then

Your specific question is answered here: https://www.sobyte.net/post/2023-04/go-test-path-main/.

Well, here’s the problem! This _testmain.go is the main package of the test executable generated by go test, and it now imports a “main” package, which is not allowed in Go.

Generally this is easily solved by moving the code you are testing to a package for example pkg/todo.go and pkg/todo_test.go or utility or whatever.

Finally if you look at that link i sent they recommend not testing main in exactly the way you are testing it. One negative of the way you are testing it is you aren’t really unit testing – every time you run main_test you compile main, this is a little unusual.

this might have some answers https://go-cloud-native.com/golang/test-the-main-function-in-go, hard to verify without a repo, also recommend you post the commands you run when seeking help.

how are you running tests (try go test ./...)? Mostly basing this on https://stackoverflow.com/questions/31352239/how-to-test-the-main-package-functions

I don’t actually care, but when I have in the past (around 2006 era) it “just worked”, while other distros i was using required more hand holding (gentoo, redhat, slackware). I suspect most distros are just fine now a days (using debian now and it seems just fine).

I am not currently using it but it’s always been fine whenever I have. What’s broken?
