Expand description

Filesystem fixtures and assertions for testing.

assert_fs aims to simplify

  • Setting up files for your tests to consume
  • Asserting on files produced by your tests

§Overview

Setting up a fixture

Validating

§Example

Here is a trivial example:

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();

Modules§

  • Filesystem assertions.
  • Initialize the filesystem to use as test fixtures.
  • Extension traits that are useful to have available.

Structs§

  • A potential file in the filesystem that is automatically deleted when it goes out of scope.
  • A directory in the filesystem that is automatically deleted when it goes out of scope.
