AWS PHP Development:
Testing Webhooks Locally for Amazon SNS
April 08, 2014 @ 11:33:07

In a previous post the AWS for PHP blog showed how to set up webhooks for handling the callbacks from their SNS messaging service. In this next part of the series they continue the process, showing how you can test these hooks locally without needing to actually send the messages. This eliminates the need to deploy to a public-facing server just to test the hooks every time you need an update.

In a recent post, I talked about Receiving Amazon SNS Messages in PHP. I showed you how to use the SNS Message and MessageValidator classes in the AWS SDK for PHP to handle incoming SNS messages. The PHP code for the webhook is easy to write, but can be difficult to test properly, since it must be deployed to a server in order to be accessible to Amazon SNS. I'll show you how you can actually test your code locally with the help of a few simple tools.

Using PHP's own built-in webserver and a tool called ngrok to tunnel from the public internet to a local server. He includes the commands to set up the PHP script directory, the code to intercept the POSTed data from the request, validate it and send the subscription confirmation request. He helps you create an SNS "topic" through the management console and walks you through a sample test request while tailing the logs.

Master Zend Framework:
Simplifying Unit Testing (and asking for help when needed)
March 20, 2014 @ 11:54:16

On Matthew Ssetter's "Master Zend Framework" blog today he talks about simplifying unit testing and some of his experience with getting too complicated in his own testing practices.

Recently I was a bit stuck, trying to figure out how to test a section of an application I've been developing. Specifically, I was trying to mock a HydratingResultSet in a controller test, so it could be the return value of a method call on a datasource, my controller needed. I was sure it was the right approach to help ensure the functionality in question was working properly. But no matter what I tried, my tests didn't work, because I wasn't mocking it correctly. [...] I asked for help [on IRC], laying out the problem as I saw it. The first response which came back, from Ocramius, stopped me dead in my tracks: "Why are you trying to do that?"

He includes a bit of background on what he was trying to test and the functionality around it and how, when he stopped to think about it, wondered why he was testing it too. He talks about the refactor he made to his code with a positive end result - the tests now passed. He suggests a few questions to ask yourself when writing your tests such as "am I doing too much?" or "am I testing code in the right place?" Chances are, if you step back and really look at what you're testing, you might realize that the answer to these questions is just to simplify.

He finishes the post with a few suggestions, some of his own personal favorites, of places you can go for help when questions do pop up. He points out that the usual excuses shouldn't be a blocker on asking for help. He is "encouraging you to set your pride, ego and excuses aside and when you're stuck: ask for help."

The PHP.cc Blog:
Disintegration Testing
March 20, 2014 @ 10:20:25

In this new post on thePHP.cc blog today Sebastian Bergmann relates the unfortunate disintegration of the Mars Climate Orbiter (back in 1999) back to a lesson on software testing and errors.

One of the most important tasks in software testing is to find the smallest scope in which a test case can be implemented. The smaller the scope in which a test is run, the faster it can be executed and the more precise its result. Unit Tests exercise one unit of code in isolation from all collaborators. Integration Tests verify the interaction of two or more collaborators in isolation from the rest of the system. Edge-to-Edge Tests run the software as end-to-end as possible in a single process (and without using a web browser or a web server). End-to-End Tests, or System Tests, look at the whole system and in the case of a web application send a HTTP request from a web browser to a web server running the software to inspect the HTTP response that is sent back.

He talks some about the difference between unit tests and acceptance tests and how "easy and seductive" functional tests can be over unit testing. He points out how fragile (and sometimes slow) this can be though, and how their failure only shows a problem and not where it is.

The promise of being able to develop both the business model as well as the software that implements it in an agile fashion should be reason enough for enterprises to invest in a modern, highly decoupled software architecture. And when the members of the software development team communicate well, both among themselves and with the other stakeholders, then there is not much that can really impede the success of the project.

SitePoint PHP Blog:
Functional Testing in Symfony2
March 04, 2014 @ 11:16:45

Taylor Ren has written up a new tutorial for the SitePoint PHP blog today walking you through a method for functional testing a Symfony application with the help of Symfony's own "WebTestCase" functionality.

In my previous article, we demonstrated how to load sample data into our Symfony development environment. The test data may not be useful as it stands on its own. When coupled with Functional Testing, however, it becomes a life saver. [...] Functional Testing is different. We don't look at the "correctness" of a single function, which should be verified by a Unit Test, but look at the bigger picture. The question answered by Functional Testing is: Is our app performing well in the sense that it displays the right content, corresponds to a user's interaction, etc?

He shows how to create a simple WebTestCase-based test to fetch the main page of a site, locate a few pieces of information and click on a certain link. Once this test passes, he adds a bit more to the test, checking the data in the page following the click.

Allan MacGregor:
Design Patterns in PHP Singletons
January 29, 2014 @ 09:25:55

Allan MacGregor has posted his latest in his look at design patterns in PHP with this most recent post about the Singleton pattern.

The singleton pattern is used to restrict the instantiation of a class to a single object, which can be useful when only one object is required across the system. Singletons are designed to ensure there is a single (hence the name singleton) class instance and that is global point of access for it, along with this single instance we have global access and lazy initialization.

He provides a basic Singleton implementation in PHP, a "User" class that always returns the same instance of itself no matter how many times the "singleton" method is called. He continues on and touches on one of the pain points around singleton use - many developers consider them an anti-pattern because their results can make it difficult to correctly test. He talks about how they break the Single Responsibility Principle (part of SOLID) and how they can hide dependency injection.

Singletons, Anti-patterns, and patterns in general are not good or bad; what makes a Singleton an Anti-pattern is not the pattern itself but how often is poorly implemented and how easy it is to do so.

QaFoo.com:
Code Reuse By Inheritance
January 20, 2014 @ 10:55:18

On the Qafoo blog today Kore Nordmann has a new post talking about code reuse through inheritance. He talks about base classes, sharing code and abstraction.

To me, inheritance has two properties: Defining an is-a relationship [and] making it possible to share code between classes by extending from a common base class. The is-a relationship between classes is one thing I like to use inheritance for. [...] The other thing you can use inheritance for is to share code between multiple classes. [...] I personally think that the latter is one of the worst things you can do in object oriented design. Bear with me for a moment and let me try to explain why I think that.

His example of doing it the wrong way is using the Active Record design pattern and how it's usually implemented - storage logic in the base class and business/table logic in the extending class. He then gets into an example that's a bit "smaller" creating diff display functionality and how the "code reuse by inheritance" creeps in a lot in helper methods. He also briefly looks at testing (or not testing) private methods and and the "Depth of Inheritance Tree" metric's recommended value.

NetTuts.com:
Acceptance Testing With Codeception
January 03, 2014 @ 11:45:39

On NetTuts.com today there's a new tutorial posted from Andrew Perkins about acceptance testing with Codeception, an alternative testing framework that's been gaining popularity in the PHP community.

Codeception is a multi-featured testing framework for PHP. It can handle unit, functional, and acceptance testing of web applications and it's powered by the already very popular PHPUnit testing framework.

Codeception allows us to test different kinds of user perspectives and site scenarios while they are visiting our app to ensure a pleasant user experience. By testing multiple scenarios, we can simulate a user's natural flow throughout our application to make sure the app is working as expecting.

The tutorial guides you through the process of getting Codeception up and running and creating a first test. The example test hits a basic PHP-enhanced HTML page to uppercase a given string. They show how to create the test skeleton and flesh it out with a test for the page load as well as the form submission.

MaltBlue.com:
Do We Use Magic Methods or Not?
December 13, 2013 @ 10:39:20

In the latest post to his MaltBlue.com site Matthew Setter takes a look at magic methods. He tries to answer a few basic questions about them - are they worth using and can you truly test effectively when they're in use.

As a freelance Zend Framework developer, I'm always looking to improve the quality of the applications I produce. So over the last 6 - 12 months, I've been learning as much as possible about testing. During this time, I've found the way I code's dramatically changing (and improving). [...] In a recent development session, I attempted to test some of my ZendDb based classes, specifically the code which used the magic methods for dynamically building where clauses. [...] I can't speak for what it's like using PHPUnit's mock objects, as I always use Mockery instead. But after attempting to do so in Mockery, I hit a stumbling block when trying to test the chained call.

His example is a call to "lessThanOrEqualTo" to create his where clause that makes use of the "__get" magic method to get and return "Where" object. After some research (and conversations on IRC) he started wondering if the magic methods were worth the trouble they may cause during testing. He references this post and lists several of the comments made about their use, most of them not in favor.

Elephant in the Room Podcast:
Episode #004 Testing Resistance
November 26, 2013 @ 09:23:13

The Elephant in the Room podcast has released their latest episode - Episode #4, "Testing Resistance":

In this episode, Konstantin and Mathias discuss some of the reasons team have trouble getting started with testing. We talk about how frameworks, and especially their documentation, do little to make it easier. But we are to blame as well: the Conference speakers, bloggers, and community leaders, talk about Quality Assurance, but we are inadvertently creating barriers. Instead of helping people, often we make it harder for them to admit to not knowing how to properly test. We discuss the need for finding the smallest testable units, and how kata's can help you get familiar with the tools. Finally, Everzet gives you some homework.

You can listen to this latest podcast either via the in-page player or by downloading the mp3 for listening offline. If you like what you hear, be sure to subscribe to their feed to get the latest.
