[−][src]Trait assert_fs::assert::PathAssert
Assert the state of files within TempDir
.
This uses IntoPathPredicate
to provide short-hands for common cases, accepting:
Predicate<Path>
for validating a path.Predicate<str>
for validating the content of the file.&Path
which must have the same file content.&[u8]
or&str
representing the content of the file.
See predicates
for more predicates.
Examples
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();
Required methods
fn assert<I, P>(&self, pred: I) -> &Self where
I: IntoPathPredicate<P>,
P: Predicate<Path>,
I: IntoPathPredicate<P>,
P: Predicate<Path>,
