minitest v0.2.0

minitest.js

• http://github.com/deanh/minitest.js

Description

A small and simple unit test framework for JavaScript based on the lovely MiniTest::Unit by Ryan Davis. It's meant to be simple and fast. It provides lots of assertions and randomizes test sequence.

CHANGELOG

0.2.0:

• Proper stack traces for errors

• Fs and Es for failures and errors as the tests run

• Optional stack traces for failures (via a constant flag)

• CamelCase everything. This breaks the API, but it was weird, needed to be done sooner, and should be easy to fix

0.1.4:

• Fixed basic messaging bugs

Synopsis

Forthcoming. For now you'll have to look at the source. Here's a start:

// in node land, you have need a runner that looks something like this:
// runner.js
#!/usr/bin/env node

var sys = require('sys'),
    fs = require('fs'),
    zombie = require('zombie'), // if you want to get headless
    MiniTest = require('minitest').MiniTest;

var files = process.argv.slice(2,process.argv.length);
var i = 0;

for(i = 0; i < files.length; i++) {
    MiniTest.Unit.newTestCase(
        require(process.cwd() + "/" + files[i]).test(zombie));
}

MiniTest.Unit.run();

// elsewhere, test files...
// test_foo.js
exports.test = (function (zombie) {
    var setupCount = 0;
    var teardownCount = 0;

    return {
        setup: function () {setupCount++},
        test1: function () {this.assert(1 === 1, "equality of 1")},
        testNoMeansNo: function () {this.assert((0 + 2) == 1, "0 + 2 = 1?")},
        testCollection: function () {this.assertEmpty([])},
        testCollection2: function () {this.assertEmpty([1,2,3])},
        testCollection3: function () {this.refuteEmpty([1,2,3])},
        testError: function () {2 = 3;},
        testSlow: function () {for(i=1000000; i>0;i--) this.assert(Math.pow(i,2)) },
        testSlow1: function () {for(i=1000000; i>0;i--) this.assert(Math.pow(i,2)) },
        testSlow2: function () {for(i=1000000; i>0;i--) this.assert(Math.pow(i,2)) },
        testSlow3: function () {for(i=1000000; i>0;i--) this.assert(Math.pow(i,2)) },
        testSlow4: function () {for(i=1000000; i>0;i--) this.assert(Math.pow(i,2)) },
        teardown: function () {teardownCount++}
    }
})

// in a browser, it's more like such:

var setupCount = 0;
var teardownCount = 0;

tests = {
     setup: function () {setupCount++},
     test1: function () {this.assert(1 === 1, "equality of 1")},
     testNoMeansNo: function () {this.assert((0 + 2) == 1, "0 + 2 = 1?")},
     teardown: function () {teardownCount++}
};

MiniTest.Unit.newTestCase(tests);
MiniTest.Unit.run();

MiniTest::Assertions provides a rich palette of assertions and refutations for crafting unit tests. See source for details.
