`assert_fs` aims to simplify

- Setting up files for your tests to consume

- Asserting on files produced by your tests

## Example

Here is a trivial example:

```rust

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();

```

See the [documentation](https://docs.rs/assert_fs) for more information.
