1//! An experimental replacement for libtest-mimic
2//!
3//! # Usage
4//!
5//! To use this, you most likely want to add a manual `[[test]]` section to
6//! `Cargo.toml` and set `harness = false`. For example:
7//!
8//! ```toml
9//! [[test]]
10//! name = "mytest"
11//! path = "tests/mytest.rs"
12//! harness = false
13//! ```
14//!
15//! And in `tests/mytest.rs` you would call [`Harness::main`] in the `main` function:
16//!
17//! ```no_run
18//! libtest2_mimic::Harness::with_env()
19//!     .main();
20//! ```
21//!
