vows
Asynchronous BDD & continuous integration for node.js
http://vowsjs.org
introduction
There are two reasons why we might want asynchronous testing. The first, and obvious reason is that node.js is asynchronous, and therefore our tests need to be. The second reason is to make test suites which target I/O libraries run much faster.
Vows is an experiment in making this possible, while adding a minimum of overhead.
synopsis
var vows = require('vows'),
assert = require('assert');
vows.describe('Deep Thought').addBatch({
'An instance of DeepThought': {
topic: new DeepThought,
'should know the answer to the ultimate question of life': function (deepThought) {
assert.equal (deepThought.question('what is the answer to the universe?'), 42);
}
}
});
coverage reporting
Code coverage reporting is available if instrumented code is detected. Currently only instrumentation via node-jscoverage is supported. When instrumented code is detected and coverage reporting is enabled using any of the --cover-plain
, --cover-html
, or --cover-json
options a code coverage map is generated.
downloading and installing node-jscoverage
node-jscoverage is a binary package that needs to be compiled from source:
$ git clone https://github.com/visionmedia/node-jscoverage.git
$ cd node-jscoverage/
$ ./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
[...]
$ make && sudo make install
instrumenting with jscoverage
$ jscoverage myfile.js myfile-instrumented.js
installation
$ npm install vows
