Inline Unit Testing with @testWith

Problem

You want to verify the correctness of a function immediately after defining it, without setting up a separate test file or complex test suite.

Idiom: Table-Driven Testing with @testWith

The @testWith decorator allows you to define a list of inputs and expected outputs directly above your function. Use the slug test runner to execute the test cases slug test slug.std (or slug -root . test hello).

@testWith(
	[1, 2], false,
	[1, 1], true,
	["1", "2"], false,
	["1", "1"], true,
	[true, true], true,
	[false, true], false,
)
var equals = fn(v1, v2) {
	v1 == v2
}
