No, docs tests are the code in Rustdoc, i.e. things like this https://github.com/unicode-org/icu4x/blob/f4fe3c5f994bc448d21660430c06ab1f429a604d/components/list/src/list_formatter.rs#L97-L121. They are run by this CI job: https://github.com/unicode-org/icu4x/blob/f4fe3c5f994bc448d21660430c06ab1f429a604d/tools/make/tests.toml#L49-L53
