Semaphore CI Blog:
Getting Started with BDD in Laravel
Aug 05, 2015 @ 09:17:43

Bruno Skvorc has written up a tutorial on the Semaphore-CI blog showing you how to get started with behavior-driven development in Laravel applications. He makes use of the Behat and PHPSpec libraries to write and execute the tests.

For many developers BDD is a complicated subject, and getting started with it the right way often does not come easy - especially when you need to implement it into an existing framework. This tutorial aims to help you get a BDD-powered Laravel project up and running in very little time, introducing you to the basic concepts and workflow you'll need to proceed on your own. We'll be installing and using Behat and PhpSpec.

He walks you through the process of getting everything you need installed: a simple Laravel application and Behat (also requiring a bit of setup to make it "play nice" with Laravel). He initializes the Behat directory and explains the concept of "context" and how to configure your Behat installation. He then gets into writing the features, creating a basic test that checks the main page of the Laravel application for the phrase "Laravel 5". A bit of additional PHP code is required to make the tests work (included) and the result is a passing test, executed with just a behat command.

The second half of the article is about PHPSpec, showing how it can be used as a sort of replacement for PHPUnit with a bit more readable syntax. He shows how to write a simple test against an object. Finally, he shows how to combine the powers of Behat and PHPSpec into a single method of testing, using PHPSpec behind the scenes in the Behat context to help with testing assertions.

Laravel, BDD and You: The First Feature
Nov 26, 2014 @ 12:19:37

NetTuts.com has posted the second part of their "Laravel, BDD and You" series (part one is here) building on their introduction in part one and building a first feature (what BDD tools call their tests).

In the second part of this series called Laravel, BDD and You, we will start describing and building our first feature using Behat and PhpSpec. In the last article we got everything set up and saw how easily we can interact with Laravel in our Behat scenarios. [...] In short, we are going to use the same .feature to design both our core domain and our user interface. I have often felt that I had a lot of duplication in my features in my acceptance/functional and integration suites. When I read everzet's suggestion about using the same feature for multiple contexts, it all clicked for me and I believe it is the way to go.

He starts in with the creation of the first feature - a simple "welcome" test that evaluates the main Laravel start page. He uses this example to set up a Laravel trait that can be reused in other parts of the testing and how to use it in a Feature Context file. He then starts to create the tests for the sample time tracking application started in part one. He gives an example of the feature file's contents, the result from its execution and the "small refactors" that it will suggest to add functionality to the feature file. With this skeleton in place, he then fleshes out the test to make it actually work with the requests. He walks through each function and provides the code needed for both the test and other tools/objects they need.

My top ten favourite PhpSpec limitations
Sep 11, 2014 @ 11:15:31

On the Inviqua techPortal today Marcello Duarte lists out his top ten favorite limitations with the PhpSpec testing tool. PhpSpec is a tool where the tests are driven by specifications, focusing on the "how".

PhpSpec is enjoying a growth in popularity lately, probably related to the recent release of 2.0. Lots of people have been playing with it and trying to get to grips with what it can do. Naturally they try to do the same things they would with other testing tools. Soon they find out they can’t. “Oh! This PhpSpec has some many limitations… I can’t do this… I can’t do that…”. Ironically, other people make positive comments about the same “limitations”. So I decided to publish a list of my top ten favourite limitations of PhpSpec, and why I love them so much.

His limitations list includes things like:

  • I can't test private methods
  • You can’t have code coverage
  • I can’t use a data provider
  • My tests can’t follow a code standard

Check out the full article for more of his list and some code examples ot help clarify each topic.

Understanding PhpSpec
Sep 04, 2014 @ 11:09:42

The NetTuts.com site (well, TutsPlus) has posted a new tutorial that gets you more intimate with PhpSpec, a PHP-based testing tool that lets you define tests as specifications and using behavior-driven development principles. If you need an introduction to the tool, check out this other tutorial first.

If you compare PhpSpec to other testing frameworks, you will find that it is a very sophisticated and opinionated tool. One of the reasons for this, is that PhpSpec is not a testing framework like the ones you already know. Instead, it is a design tool that helps describing behavior of software. A side effect of describing the behavior of software with PhpSpec, is that you will end up with specs that will also serve as tests afterwards. In this article, we will take a look under the hood of PhpSpec and try to gain a deeper understanding of how it works and how to use it.

They provide a quick overview of some of the internals of the PhpSpec tool and a brief look at the difference between BDD (behavior-driven) and TDD (test-driven) development practices. There's also a look at how the tool differs from the popular PHP testing tool PHPUnit. Code examples are provided through out the post with simple tests, making the separation between the methods and tools easier to follow.

A BDD Workflow With Behat and Phpspec
Jul 04, 2014 @ 14:20:23

NetTuts.com has posted a new tutorial today showing a sample testing BDD workflow using the Behat and PHPSpec testing tools. The BDD (behavior-driven development) approach focuses on using test-driven development and domain-driven design rather than just a unit testing approach.

In this tutorial, we will have a look at two different BDD tools, Behat and phpspec, and see how they can support you in your development process. Learning BDD can be confusing. New methodology, new tools and many questions, such as "what to test?" and "which tools to use?". I hope that this rather simple example will give you ideas to how you can incorporate BDD into your own workflow.

The article isn't a "getting started with BDD" guide, so you'll need to know a bit about the ideas and process before getting into it. He starts with a look at the workflow Taylor Otwell (his inspiration for this) uses and how to install Behat and get to work on a first feature file. He describes the thought process behind the steps and some of the PHP code required to make them work. He then gets to the use of phpspec to mock out a needed "Config" dependency. He works though the rest of the tests and includes the output when all tests are passing.

Getting Started With Phpspec
May 12, 2014 @ 13:55:10

The NetTuts.com site has a new tutorial that want to help get you started with PHPSpec, the PHP-based tool to help with behavior-driven development.

In this short, yet comprehensive, tutorial, we'll have a look at behavior driven development (BDD) with phpspec. Mostly, it will be an introduction to the phpspec tool, but as we go, we'll touch on different BDD concepts. BDD is a hot topic these days and phpspec has gained a lot of attention in the PHP community recently.

They briefly introduce behavior-driven development (BDD) and where the PHPSpec tool fits into the picture. They guide you through installation of the tool (via Composer) and some configuration updates to get things set up. From there, they help you write your first spec, a test to see if a "TaskCollection" can be created. They build on this simple test adding in checks for adding tasks, making the collection countable and working with expectations and promises. The last part of the tutorial mentions how to make custom matchers like "beTrue" and "beFalse" and the output of the full test set.

Chris Hartjes:
PHPSpec and the New Wave of Testing
Oct 19, 2012 @ 08:42:18

Chris Hartjes, a big proponent of testing in web applications (mostly in the PHP realm so far) has a new post to his site with some of his thoughts about PHPSpec, the specification-driven testing tool recently released by the same folks who made Behat.

I think that we are witnessing the first wave of new testing tools in the PHP community that allow developers to wrap their applications in automated tests. I am familiar with the BDD-style that is being promoted in PHPSpec, through my work with Behat to create automated user acceptance tests. I think if you want a tl;dr version of PHPSpec I would tell you “write hybrid unit/integration tests using plain language”.

He notes that writing code to match a specification has similar concepts to using unit testing for TDD (with something like PHPUnit). He points out a few interesting things like the use of mock objects and the fact that you'll still need to write some code to make tests work - that's unavoidable right now.

Beyond TDD with PHPSpec
Aug 03, 2011 @ 09:41:20

On the Ibuildings techPortal today there's a new post from Marcello Duarte following up on his previous post looking at behavior driven development (here) with a look at PHPSpec, a port of RSpec that is the first PHP BDD framework.

PHPSpec is the first ever PHP BDD framework. It is a port of RSpec to PHP created back in 2007 by Padraic Brady and Travis Swicegood. Development in this framework stopped for a while and was reignited last August (2010).

He goes over how to get it installed via PEAR and how to write some sample tests following along the topic from his previous post (handing videos and reviews). He gets into a bit more detail by describing how MVC is handled with PHPSpec and how the Zend Framework command line tool can be used to create a controller that satisfies the test.

PHPSpec: BDD for your classes
Jun 03, 2011 @ 08:57:12

In a new post to the "PHP on Windows" section of DZone.com, Giorgio Sironi looks at another testing tool to add to your arsenal - PHPSpec, a behavior-driven development testing tool similar to Ruby's RSpec.

Behavior-Driven Development can be seen as an evolution of Test-Driven Development, stricly in its outside-in version and with a refined language. In the case of the tool I'm reviewing today, BDD is implemented with code instead of with textual feature files (e.g. written in Gherkin) like in Behat. PHPSpec is similar to (or a port of) RSpec, the original BDD Ruby tool. It fills the need for an approach different from the classical xUnit at the class level.

He points out the place he thinks PHPSpec has in the software testing world as it fits with things like Behat and PHPUnit. He also includes some sample code to show it at work - a sample test that checks against an object for things like "should be an object" or "should not return the same number for multiples of three" for the basic class FizzBuzz.

Padraic Brady's Blog:
A Domain Specific Language for Behaviour Driven Development (BDD) in PHP
Jul 21, 2008 @ 11:13:35

Padraic Brady has posted about a part of his PHPSpec library, the domain specific language.

PHPSpec implements a domain specific language (DSL) in PHP for specifying the behaviour of functional units such as methods and objects. The purpose of a DSL was to move away from the xUnit style declaration of tests towards a specification language centred on describing behaviour.

He illustrates with a bowling example - described with a sample class (with a itShouldScore0ForGutterGame test) and how to use it to fit his proposal:

My proposal therefore is to re-implement the current programming language DSL as a specification language - i.e. a new (extremely limited and narrow!) language capable of being parsed by PHPSpec into its PHP equivalent. [...] Using a specification DSL, we can simply ignore the existence of classes in PHP (well, the pretense is nice). Instead the DSL would incorporate a syntax for denoting shared behaviours.
