Mocha is a JavaScript test framework running on node.js, featuring browser support, asynchronous testing, test coverage reports, and use of any assertion library.[1]
Assertion Libraries
Mocha can be used with most JavaScript assertion libraries, including:
- should.js
- express.js
- chai
- better-assert
- unexpected
Usage and examples
$ npm install -g mocha
$ mkdir test
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);
})
})
})
