Unit.js is an open source unit testing framework for the JavaScript programming language.[1]

Usage

A simple hello world test looks like the code below.

  var example = 'Hello world!';

  test.string(example)
    .isEqualTo('Hello world!');


Support describe() and it(), describes a suite of tests and it() is an individual test specification. The name "it()" follows the idea of behavior-driven development and serves as the first word in the test name, which should be a complete sentence.

describe('Hello world', function() {
  it('says hello', function() {

    var example = 'Hello world!'; 

    test.string(example)
     .isEqualTo('Hello world!');
  });
});

Assertion styles

Unit.js has multiple interfaces that allow the developer to choose the most comfortable and productive style.

Unit.js :

test.string(str)
  .number(num).is(42);

Assert :

test.assert(typeof str === 'string');
test.assert(typeof num === 'number');
test.assert.equal(num, 42);

Must.js :

test.must(str).be.a.string();
test.must(num).be.a.number();
test.must(num).equal(42);

Should.js :

test.should(str).be.a.String
test.should(num).be.Number
.and.equal(42);
