Tii is an small assertion library and test runner.

Supported assertions:

• Inequality using lodash isEqual.
• Truthy
• Falsy
• Gratter
• Smaller

##installation

$ npm install tii

##usage

import Tii from 'tii';
// or
require('tii');

var myTests = new Tii();

// --- assert equal ---
myTests.when('1 equal 1').should(1).equal(1);

// --- assert inequality ---
myTests.when('1 not 2').should(1).not(2);

// --- output the short results ---
myTests.results();

##methods

Tii.setUp(callback): sets a callback to run before every test.

Tii.clenUp(callback): sets a callback to run before every test.

Tii.results(): short log of the results of the assertions plus a log of the failing ones, if there are some :wink:

Tii.verboseOutput(verbose = true): Sets/unsets the verbose output. You can set and unset for specific assertions.

myTests.verboseOutput(); // following assertions will have verbose output
		
		. . . do some assertions here . . .
		
myTests.verboseOutput(false) // further assertions will not output the result

Tii.when(description): Adds an assertion and stores its optional description. Chainable.

Tii.should(a): Stores the first value of the assertion, into the last assertion added. Chainable.

##assertion methods

this methods run set up callback, the assertion and the clean up callback.

a is the first value added through Tii.should(a);

Tii.equal(b): expects isEqual(a,b) to be true.

Tii.not(a): expects !isEqual(a,b) to be true.

Tii.beTrue():expects !!a to be true.

Tii.beFalse():expects !a to be true.

Tii.beMore():expects a > b to be true.

Tii.beLess():expects a < b to be true.
