Vinegar
A collection of functions and macros to help testing Rust code.
Macros
expect
checks a boolean condition, similar toassert
.expect_eq
checks two values for equality, similar toassert_eq
.
Functions
fn check<I>(expects: I) where I: IntoIterator<Item=Result<(), String>>
Takes a collection of Result<(), String>
, which happens to be the type of values
returned by the expectation macros.
So, the check
function is, basically, meant to check the assertions made with
the expect
macros.
Usage
Example usage:
use vinegar::check;
#[test]
fn use_check() {
// simple test: just check some expectations:
check(vec![
expect_eq!(2 + 2, 4),
expect!(2 + 2 == 4),
expect_eq!("hi", "hi"),
]);
// simple example-based test
let examples = [1, 2, 3, ];
check(examples.iter().map(|&ex| expect!(ex > 0)));
// example-based test with both input and assertion as examples
let examples = vec![
// (input, expected result)
(1, 2),
(2, 4),
(3, 6),
];
check(examples.iter().map(|&(input, expected)| {
let result = input * 2;
expect_eq!(result, expected)
}));
}
