Huck - PHP Testing Framework

describe('Huck Fin', function() {

   it('should be Huck', function() {

   it('should not be Huck', function() {


Huck is a Behavior Driven Development (BDD) framework based on Jasmine for JS. It is designed with a simple syntax to give it a fast learning curve.

Getting Started

Huck runs in the browser so you don’t have to load terminal. Just upload it to your server, create the specs and load index.php. Huck will automatically find all files in specs/*_spec.php and run them.

Why did I write this?

I know there are a bunch of test suites for PHP, but I wanted to build my own for the experience. Plus, I didn’t like the syntax or result format other suites had.

Whenever you are tempted to type something into a print statement or a debugger expression, write it as a test instead. Martin Fowler

Writing a Spec

// specs/first_spec.php
describe('This is my Test Suite', function() {


All specs need to be placed inside of the ./specs directory and the filename must end in _spec.php for Huck to find it. Huck will autoload each file and run the tests so you don’t have to worry about that part.

require '/path/to/User.php';

// specs/user_spec.php
describe('User Class Functionality', function() {

    it('should authenticate user', function() {
       expect(User::authenticate('BaylorRae', 'pass'))->toBeInstanceOf('User'); 

    it('should not authenticate user', function() {
       expect(User::authenticate('BaylorRae', 'wrong password'))->not->toBeInstanceOf('User'); 


Once you have described your spec you can add your tests. The syntax is designed so you can read each line and understand what’s going on.

Notice that in the second test I was able to make sure that it did not return an instance of User. Normally the User::authenticate() method would return false and the test would be expect($x)->toBeFalsy() but I wanted to show how to invert the test.

Matchers and how to write them

Huck comes with a number of matchers that should be more than enough in most cases. The full list is on [GitHub in the Readme][huck_matchers].

Here are a couple of my favorites

expect($x)->toMatch($pattern) # compares $x to regular expression $pattern
expect($x)->toBeArray() # makes sure $x is an array
expect($x)->toBeTruthy() # checks to see if $x === true

The Syntax


 * Checks to match length of an array
 * @param $actual the value passed into expect()
 * @param $expected the value passed into ->toBeLength()
 * @author Baylor Rae'
Huck::addMatcher('toBeLength', function($actual, $expected) {
    if( !is_array($actual) && !is_array($expected) )
        return false;

    return count($actual) === count($expected);

Let me know what you think and/or what you would like to see added to framework. This is the first testing framework that I’ve written and I’m not completely sure everything is perfect yet. If you have any suggestions please let me know.
