Assertor

Assertor makes test assertions and failure messages more human-readable.

Assertor is heavyly affected by Java Truth in terms of API design and error messages. Assertor is a totally different project from Java Truth.

Disclaimer

This is not an official Google product, it is just code that happens to be owned by Google.

Example

```rust use assertor::*;

[test]

fn testit() { assertthat!("foobarbaz").contains("bar"); assertthat!("foobarbaz").endswith("baz");

assert_that!(0.5).with_abs_tol(0.2).is_approx_equal_to(0.6);

assert_that!(vec!["a", "b"]).contains("a");
assert_that!(vec!["a", "b"]).has_length(2);
assert_that!(vec!["a", "b"]).contains_exactly(vec!["a", "b"]);

assert_that!(Option::Some("Foo")).has_value("Foo");

} ```

Failure cases

```rust use assertor::*;

fn testit() { assertthat!(vec!["a", "b", "c"]).contains_exactly(vec!["b", "c", "d"]); // missing (1) : ["d"] // unexpected (1): ["a"] // --- // expected : ["b", "c", "d"] // actual : ["a", "b", "c"] } ```
