A collection of assertion macros for unit testing in Rust.

Enums

assert_ok!()

let result = "5".parse::<u32>(); assert_ok!(result);

assertok!().withvalue()

let result = "5".parse::<u32>(); assert_ok!(result).with_value(5);

assert_err!()

let result = "z".parse::<u32>(); assert_err!(result);

assert_some!()

let option = "5".parse::<u32>().ok(); assert_some!(option);

assertsome!().withvalue()

let option = "5".parse::<u32>().ok(); assert_some!(option).with_value(5);

assert_none!()

let option = "z".parse::<u32>().ok(); assert_none!(option);

Collections

assert_contains!()

let vec = vec![1, 3, 5, 7, 9, 11, 13, 15, 17, 19]; let x = 5; assert_contains!(&vec, &x);

let mut map = HashMap::new(); map.insert("a", 1); map.insert("b", 3); let pair = (&"a", &1); assert_contains!(&map, pair)

assert_all!()

let vec = vec![1, 3, 5, 7, 9, 11, 13, 15, 17, 19]; assert_all!(&vec, |&x| x > 0, "all > 0");

assert_any!()

let vec = vec![1, 3, 5, 7, 9, 11, 13, 15, 17, 19]; assert_any!(&vec, |&x| x > 0, "any > 0");

Inequalities

``` assertlt!(x, y) // less than assertle!(x, y) // less or equal

assertgt!(x, y) // greater than assertge!(x, y) // greater or equal ```
