To use Hamcrest, add this to your Cargo.toml
:
``` [dev-dependencies.hamcrest]
git = "https://github.com/carllerche/hamcrest-rust.git" ```
And this to your crate root:
``` rust
extern crate hamcrest; ```
After a quick cargo build
, you should be good to go!
Hamcrest supports a number of matchers. You'll have to use
them just like any other Rust library. Alternatively you can also use
all of them at once like this:
rust
use hamcrest::prelude::*;
rust
assert_that(1, is(equal_to(1)));
rust
assert_that(1e-40f32, is(close_to(0.0, 0.01)));
assert_that(1e-40f32, is_not(close_to(0.0, 0.000001)));
rust
assert_that(&path, is(existing_path()));
assert_that(&path, is(existing_file()));
assert_that(&path, is_not(existing_dir()));
rust
assert_that(None, is(none::<int>()));
assert_that(Some(1), is_not(none::<int>()));
``` rust assertthat(&vec!(1i, 2, 3), contains(vec!(1i, 2))); assertthat(&vec!(1i, 2, 3), not(contains(vec!(4i))));
assertthat(&vec!(1i, 2, 3), contains(vec!(1i, 2, 3)).exactly()); assertthat(&vec!(1i, 2, 3), not(contains(vec!(1i, 2)).exactly())); ```
rust
assert_that("1234", matches_regex(r"\d"));
assert_that("abc", does_not(match_regex(r"\d")));
