Jumpstart Your PHP Testing with Codeception
May 26, 2016 @ 12:41:35

The Toptal.com blog has posted a new tutorial that wants to help you make the most of your application via testing. They show you how to use Codeception to create a set of tests to ensure your application is working as expected.

Before moving on to Codeception and PHP, we should cover the basics and start by explaining why we need testing in applications in the first place. Perhaps we could complete a project without wasting time on tests, at least this time?

Sure, you don’t need tests for everything; for example, when you want to build yet another homepage. [...] However, you definitely do need testing when: your team uses BDD/TDD, your Git repo contains more than a couple commits, [and] you are a proper professional, working on a serious project.

They start with a look at the kinds of things testing solves in your development process and the different kinds of tests you can create. From there they introduce Codeception, an alternative testing tool to the widely used PHPUnit. The tutorial helps you get it installed and shows you how to make a simple, first test. It helps you execute the test, debug issues that might pop up and the different assertions you can use. With the fundamentals in place, they move on to more details on using it for functional and unit testing.

Acceptance Testing a Laravel and Vue.js Application
May 20, 2016 @ 11:57:28

Mohamed Said has written up an article about acceptance testing a Laravel+Vue.js application with the help of the Selenium WebDriver functionality.

The good thing about writing tests at a mature stage of the project is that many of the basic parts of the application are settled down, major changes have slowed, so deciding the shape of tests can happen in a more solid way. Testing too early, in my opinion, leads to the need of changing tests whenever you change functionality, so it’s work * 2.

This post is about a single type of tests and I think it’s the most interesting one.

He starts with a brief description of what acceptance testing is for those not familiar with the concept. He then gets to the Selenium WebDriver, provides a summary on that as well and points out the main tool they use for their tests: the Javascript driver it provides. the syntax on the driver is a bit difficult to follow so they also suggest layering Nightwatch.js on top to make for simpler, cleaner and easier to read tests. There's also information and (acceptance) testing the backend of the application with various tools, ultimately deciding on the use of Codeception.

Master Zend Framework:
How to Test Zend Framework Applications with Codeception - Part Two
Oct 26, 2015 @ 09:31:13

The Master Zend Framework site has posted the second part of their tutorial series showing how to test Zend Framework applications with CodeCeption, a tool allowing for behavior-driven testing methods on PHP applications. In part two of the series they finish up the examples from part one and put them to use.

In part one of this series on testing Zend Framework applications with Codeception, we covered what Codeception is, how to install and configure it, and how to enable and configure the Zend Framework 2 module; finishing up by writing some basic acceptance and functional tests. [...] Here, in part two of the series we see how to retrieve and test registered services using BDD-style testing. This isn't going to be an exhaustive look at every possibility of what's available. Instead, what I'm going to do is show a simple set of examples which use two extra modules which come with Codeception and how they enable descriptive, BDD-style, tests.

The tutorial starts by getting into a bit more detail on what BDD-style testing is and some of the basic terminology. They help you install two modules to help make writing your tests simpler. The tutorial walks you through generating a new test for a fictional "Video" table gateway class and how to flesh it out to pull the service from the service manager, configure the database connection and write a few checks to verify the type of the service fetched and the number of records it returns.

Hafiz Waheeduddin Ahmad:
API Testing: Installing and Using Codeception
Jun 15, 2015 @ 15:45:41

Hafiz Waheeduddin Ahmad has a new post to his site, part three of a series he's posted on API testing, looking at the use of Codeception for testing API output and functionality.

In this post, we will have a look on how we can use Codeception for API testing.

He starts by helping you get Codeception installed through Composer through a "require" command line call. He then walks you through the setup of the project and how to use the "codecept" command line tool. He covers the generated directory structure the bootstrapping created and how to set up a sample configuration for your API. He then gets into writing an example test, showing how to check things like authentication, HTTP header information, response codes and response contents. Finally he shows how to run the tests in both a normal and more verbose way.

Matthew Turland:
Customizing Codeception Database Cleanup
May 12, 2014 @ 11:15:24

If you're a Codeception user, you'll find Matthew Turland's latest post interesting. In it he shares a way to customize database cleanup between the tests. Codeception handles it a bit differently that how PHPUnit's Db module does.

Recently, I was looking into ways to speed up the runtime of the test suite at Blopboard. We use the Codeception framework to write functional tests for our REST API, part of which entails putting the database into a known state using Codeception’s Db module. The behavior of this module is similar to that of the PHPUnit Database extension with one exception: where PHPUnit only truncates tables and leaves their schemas intact, Codeception removes the database structure and expects the SQL dump it uses to recreate it between tests. I must admit to not understanding this design decision of Codeception, nor attempts to clarify it.

He admits that his solution is "a bit hacky" but it does work to truncate the table rather than drop the entire schema and wait for a rebuild. His "DbHelper" class is used in place of the Db module. He traced through the execution path of the Db module and found a "hook" where he could override the "cleanup" method to prevent the schema drop and replace it with a truncate. He also includes code for a suggested addition to Codception that would handle the same thing in a more integrated way.

Acceptance Testing With Codeception
Jan 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.

Nothing is Untestable: AspectMock in Action
Aug 01, 2013 @ 11:26:12

On the Codeception site they've posted a guide to using the AspectMock feature of the testing tool to prove that "nothing is untestable."

We already announced AspectMock, the mocking framework that may dramatically change the way you do testing in PHP. In this video Jeffrey Way shows how AspectMock is different from others. In this post we will demonstrate its powers too, and we will try to break some stereotypes about PHP testing. To get the code tested, you should always keep in mind how you would write a test for it. We know unit testing requires some good practices to follow and bad practices to avoid.

Their first example involves testing singletons, notorious for being difficult to test because of their "global" state. He also gives a more practical example using a Yii2-based application and a login form. True to its name, the AspectMock uses Aspect Oriented Programming concepts to make the "magic" happen behind the scenes.

Getting on Testing Ship
Jun 13, 2013 @ 11:06:54

On the Codeception blog there's a new post that advocates getting on the testing ship even if the project you're currently on isn't using tests (or TDD).

In this blogpost we will try to figure out how to get faster into the testing. What tests to write at first? Let's say we already have a project and we didn't practice TDD/BDD developing it. Should we ignore testing at all? Definitely no. So where should we start then?

They suggest a three-tiered pyramid approach - UI at the top, Integration testing in the middle and Unit testing as the foundation. They talk about the times when testing doesn't make sense, like when your application is based on a third-party tool (like WordPress or Drupal). They recommend starting with functional testing and working your way back down, especially if your framework supports it. Obviously they encourage the use of Codeception for it, but also recommend even something like Selenium tests if nothing else.

Headless Browser Testing with Selenium2 and PhantomJS
May 29, 2013 @ 11:13:58

On the CodeCeption blog they have an example if how to use the testing tool to run headless with Selenium2 and PhantomJs to work with Javascript or DOM elements in the page.

The latest version of PhantomJS is an easy to install, stand-alone binary that doesn't require installing Node.js or any other dependencies, and ships with its own 'Ghost Driver' for implementing the WebDriver Wire Protocol. Which means you can drive it using the Selenium2 driver in Codeception, and anything that you can test in Chrome, Firefox, Safari, or IE using Selenium2, you can now test in half the time using PhantomJS.

They help you get the tools you need installed and show you how to start up the Selenium server and connect PhantomJS to it. Then you just run the acceptance tests for your application and get some feedback directly in the terminal window from the execution.

Headless testing can be a bit of a challenge, since it's impossible to 'see' what failed. But in this case, Codeceptions default logging and screenshot capture on failure can be extremely helpful, since you can then actually see the state of the browser at the point of failure.

Specification or Testing: The Comparison of Behat and Codeception
May 08, 2013 @ 09:28:34

On the Codeception site today there's a new post that compares their tool, Behat and PHPUnit for testing your applications.

This is guest post by Ragazzo. He uses Behat as well as Codeception for making his project better. He was often asked to do a comparison between Codeception, Behat, and PhpUnit. In this post he explains the commons and different parts of this products.

The author talks some about the difference between functional/acceptance tests and how they fit in with behavior driven development. He includes some examples of Behat test formats (Gherkin) and how it can be used for both the functional and acceptance side of things. He also talks some about why he prefers Codeception over Behat(+Mink) for his testing. A sample Codeception test is included, showing a login form check.
