stack ghci foo:test:bar uses library dependencies unless --test is passed #1845
Description
stack: Version 1.0.4 x86_64
This took me a while to figure out because the error message isn't clear, it turns out that you need to pass --test when ghci'ing a test suite, otherwise the library dependencies will be in scope instead.
Edit: I would expect --main-is *:test:* to either imply --test or produce an error message without it, the former sounds nicer to me.
$ stack ghci feed --main-is feed:test:tests
