test.assert(condition: Bool) -> ()
test.assert(condition: Bool, message: String) -> ()

Panics if condition is false. The optional message is included in the error.

import test
fn main() {
    test.assert(1 + 1 == 2)

test.assert_eq(left: a, right: a) -> ()
test.assert_eq(left: a, right: a, message: String) -> ()

Panics if left != right, displaying both values.

import test
import list
fn main() {
    test.assert_eq(list.length([1, 2, 3]), 3)
    test.assert_eq(1 + 1, 2, "addition")
}

test.assert_ne(left: a, right: a) -> ()
test.assert_ne(left: a, right: a, message: String) -> ()

Panics if left == right, displaying both values.
