Description: add feature gates to tests for no-default-features compatibility
The crate fails to build when tested with --no-default-features despite
advertising no_std support. This patch adds conditional compilation to
tests that require std and rand features, allowing minimal feature builds
to succeed by skipping incompatible tests rather than failing compilation
