Unit.js is an open source unit testing framework for the JavaScript programming language,[1] running on Node.js and the browser.
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);
