Struct test_casing::Product

pub struct Product<Ts>(pub Ts);

Expand description

Cartesian product of several test cases.

For now, this supports products of 2..8 values. The provided IntoIterator expression for each value must implement Clone. One way to do that is using TestCases, which wraps a lazy iterator initializer and is thus always Copyable.

§Examples

let product = Product((0..2, ["test", "other"]));
let values: Vec<_> = product.into_iter().collect();
assert_eq!(
    values,
    [(0, "test"), (0, "other"), (1, "test"), (1, "other")]
);
