jsUnity

What is it?

jsUnity is a lightweight, environment-agnostic JavaScript testing framework: It doesn’t rely on any browser capabilities and therefore can be used in any client-side or server-side JavaScript environment.

Why jsUnity?

There are already several unit testing frameworks for JavaScript that are browser-centric. jsUnity aims to just focus on JavaScript as a language that’s used beyond the browser context.

In a nutshell…

The most concise way of running a test suite with jsUnity:

var results = jsUnity.run(function () {
    function testSomething() {
        jsUnity.assertions.assertTrue(someFlag);
    }
});

Alternative ways for defining test suites:

function testSuite1() {
    function testSomething1() {}
}

var testSuite2 = {
    suiteName: "testSuite2",
    testSomething2: function () {}
}

function testSomething3() {}
var testSuite3_1 = [ testSomething3 ];
var testSuite3_2 = [ "testSomething3" ];

var testSuite4 = "function testSomething4() {}";

jsUnity.log = function (s) {
    document.write("<div>" + s + "</div>");
};
jsUnity.run(testSuite1, testSuite2,
    testSuite3_1, testSuite3_2, testSuite4);

Here’s the output you’d get from the above:

Running testSuite1
1 test found
[PASSED] testSomething1
Running testSuite2
1 test found
[PASSED] testSomething2
Running unnamed test suite
1 test found
[PASSED] testSomething3
Running unnamed test suite
