libtest2-mimic 0.0.1

//! An experimental replacement for libtest-mimic
//!
//! # Usage
//!
//! To use this, you most likely want to add a manual `[[test]]` section to
//! `Cargo.toml` and set `harness = false`. For example:
//!
//! ```toml
//! [[test]]
//! name = "mytest"
//! path = "tests/mytest.rs"
//! harness = false
//! ```
//!
//! And in `tests/mytest.rs` you would call [`Harness::main`] in the `main` function:
//!
//! ```no_run
//! libtest2_mimic::Harness::with_env()
//!     .main();
//! ```
//!
