//! Filesystem fixtures and assertions for testing.
//!
//! Fixtures:
//! - A sandbox to work within (see [`TempDir`]).
//! - Setup the sandbox (see [`FileTouch`], [`FileWriteBin`], [`FileWriteStr`], [`PathCopy`]).
//!
//! For assertions, see [`PathAssert`].
//!
//! ```toml
//! [dependencies]
//! assert_fs = "0.11"
//! ```
//!
//! ## Overview
//!
//! Setting up a fixture
//! - [`TempDir`] or [`NamedTempFile`]
//! - [`touch`][`FileTouch`] a [`ChildPath`] or [`NamedTempFile`]
//! - [`write_binary`][`FileWriteBin`] a [`ChildPath`] or [`NamedTempFile`]
//! - [`write_str`][`FileWriteStr`] a [`ChildPath`] or [`NamedTempFile`]
//! - [`write_file`][`FileWriteFile`] a [`ChildPath`] or [`NamedTempFile`]
//! - [`copy_from`][`PathCopy`] a pristine folder to a [`ChildPath`] or [`TempDir`]
//!
//! Validating
//! - [`assert`][`PathAssert`] a [`ChildPath`], [`TempDir`], or [`NamedTempFile`]
//!
//! ## Example
//!
//! Here is a trivial example:
//!
//! ```rust
//! extern crate assert_fs;
//! extern crate predicates;
//!
//! use assert_fs::prelude::*;
//! use predicates::prelude::*;
//!
//! let temp = assert_fs::TempDir::new().unwrap();
//! let input_file = temp.child("foo.txt");
//! input_file.touch().unwrap();
//!
//! // ... do something with input_file ...
//!
//! input_file.assert("");
//! temp.child("bar.txt").assert(predicate::path::missing());
//!
//! temp.close().unwrap();
//! ```
//!
