  • tempfile

    Temporary file library for rust

    Project mention: Hey Rustaceans! Got a question? Ask here (27/2023)! | /r/rust | 2023-07-03

    The static-assertions crate tries to handle similar use cases but const generics are still problematic.

  • cargo-hack

    Cargo subcommand to provide various options useful for testing and continuous integration.

    Project mention: What are some useful tools for Rust? | /r/rust | 2023-05-03

    cargo-hack for workspaces or projects that make heavy use of crate features

    Organized, flexible testing framework for Rust

  • fuzzcheck-rs

    Modular, structure-aware, and feedback-driven fuzzing engine for Rust functions

  • faux

    Struct mocking library for Rust

    Project mention: Mocking in Rust: Mockall and alternatives | | 2023-05-23

    Faux allows you to create mock versions of a struct without complicating your code. Like many mocking libraries, faux is only recommended for testing purposes. Mock objects in production may be unstable and cause production problems.
