# assert_fs
> **Assert Filesystems** - Filesystem fixtures and assertions for testing.
[][Documentation]
[][Crates.io]
`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.
