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();
