Mocha is a JavaScript test framework for Node.js programs, featuring browser support, asynchronous testing, test coverage reports, and use of any assertion library.[1]
Assertion libraries
[edit]Mocha can be used with most JavaScript assertion libraries, including:
- should.js
- express.js
- chai
- better-assert
- unexpected
Usage and examples
[edit]$ npm install -g mocha $ mkdir test $ $EDITOR test/test.js # or open with your favorite editor var assert = require("assert") describe('Foo', function(){ describe('#getBar(value)', function() { it('should return 100 when value is negative') // placeholder it('should return 0 when value is positive', function() { assert.equal(0, Foo.getBar(10)); }) }) }) $ mocha . 1 test complete (1ms)
For asynchronous testing, invoke the callback, and Mocha will wait for completion.
describe('Foo', function(){ describe('#bar()', function() { it('should work without error', function(done) { var foo = new Foo(128); foo.bar(done); }) }) })
