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
