Zig by Example: Test

Zig has it’s own syntax to write tests, using the `test` keyword.	`const std = @import("std");`
	`fn add(a: usize, b: usize) usize { return a + b; }`
Tests can also appear in the same file as a `pub fn main`.	`test "add" { const x = 1; const y = 2; const result = add(x, y);`
	`try std.testing.expect(result == 3); }`

Use zig test to run the tests defined.

$ zig test test.zig
All 1 tests passed.
