Simple Test

Simple Test is a tiny, straightforward testing framework. It provides a single assertion model, doesn't perform deep comparisons and uses same-value equality for your tests.

Getting Started

Set up your HTML document like this:

<!doctype html>
<meta charset=utf-8>
<link rel=stylesheet href=style.css>
<title>Unit tests</title>

<main><h1></h1></main>

<script src=setup.js></script>
<script src=tests.js></script>

Write tests in your tests.js file:

test("My first test", assert => {
  assert("".charAt(0), "", "returns an empty string");
  assert([1, 2].map(n => n + 1), [2, 3], "increments each number in an array");
  assert({ a: "1", b: "2" }, { a: 1, b: 2 }, "values should be numbers");
});

Result: 2 tests passed, 1 failed.
