nocapture for doc-tests

[diwic]

Hi,

For ordinary tests, I can run cargo test -- --nocapture and the output will shown on-screen. However, I have doc-tests as well (examples in the documentation), and even though I use --nocapture the output of these are not shown.

I'm not sure whether this is a bug in cargo or somewhere else, but at least the behaviour is inconsistent.

Are you sure that this doesn't work? I just ran cargo test -- --nocapture and saw all the output from the doctests (the compiles). The actual output of the tests themselves isn't printed anywhere, but that's a rustdoc issue, not a Cargo one.

Right, that's what I'm missing.

Linking the follow-up pull request since this issue is what comes up in a Google search. Rustdoc fixed the issue in 2021. There was a pull request to fix the issue in Cargo, but the pull request was never resolved: #9705.

I also tried to get output from println. There is no output yet.
No output from println! and eprintln! .
