Why Testing is Important ?
Beginner PHP developers tend not to compose tests for their code. The greater part of us started our careers by testing new features and functions we had quite recently written in the program window one by one, and when something turned out badly we were clueless regarding what to do.
Writing tests for our code can save valuable debugging time and hours of a cerebral pain. At the point when untested code goes into production, the reviews we’ll get most likely won’t be so pleasant. So what can we do?
Probably the best idea is to establish a productive testing workflow in which we need to write our own testing code that checks if our application code works properly.
The trick is that the testing code should be composed before the application code. Along these lines we can guarantee from the earliest starting point that the code we compose works legitimately. The testing code will go into discrete records. On the off chance that we later chance upon any mistakes in our PHP application, we don’t have to do whatever else, simply run our tests that ideally will give us appropriate insights about the issues.
Other than saving time and properly preparing our app for production, testing has many other advantages too, such as:
- More Maintainable Code
- Facilitated Refactoring
- Less security issues
- Less bloated code base (adapting the application code to the pre-written test code will make us omit superfluous parts)
- Better Performance
PHPUnitis the best-known testing system for composing Unit Tests for PHP applications. Unit tests take little segments of code called units and test them one by one. With the assistance of PHPUnit we can direct test-driven advancement.
It tends to be used via the command line, and it gives us a convenient TestCase class that we can reach out as indicated by our necessities. PHPUnit likewise enables developers to use pre-written assertion methods to assert that the app behaves a certain way
Codeception doesn’t just empower us to compose Unit Tests, yet additionally Functional and Acceptance Tests. These two last tests the PHP application overall with all highlights integrated, not as units. Codeception enables us to empower and design distinctive modules as per our improvement needs.
It’s coordinated with numerous PHP development framework, for example, Symfony2, Laravel4, Yii, Phalcon, and the Zend Framework. This implies we can utilize a PHP automation testing framework and a PHP development framework together to build up a super efficient development work process.
Behat is a prevalent conduct driven PHP testing framework. The tests we can compose with Behat look preferably like stories over code. Behat utilizes the StoryBDD subtype of behaviour-driven development (the other subtype is SpecBDD).
The framework was enlivened by the Cucumber projectthat is a testing framework for the Ruby programming language.
PHPSpecadditionally pursues the behaviour-driven testing approach, however its other subtype called SpecBDD. With PHPSpec we have to compose the details first that describe how the application code will act. It was additionally motivated by a Ruby testing framework called RSpec.
Storyplayer is a full-stack testing framework that makes it conceivable to write end-to-end tests for an entire platform. Storyplayer has support for creating and destroying test environments on demand. It pursues the TDD testing approach, and enables us to write functional tests that can check an application overall.
Peridot is a lightweight, extensible testing framework for PHP. It includes an event-driven architecture that enables testers to effectively customize the framework via plugins and reporters.
Peridot utilizes the describe-it syntax to build up a clear and readable testing language that clearly describes how our application code should behave.
Atoum is a natural and present day PHP testing framework that enables us to run unit tests. It simplifies test development, and as it’s a young framework it utilizes some more up to date abilities that were presented in PHP 5.3 (it can‘t be used with older PHP versions) to provide us with a speedy and easy-to-understand testing process.
Atoum ensures a high level of security during test execution, as it isolates each test method in its own PHP process.
Kahlan is a full-highlighted BDD testing framework that makes it conceivable to compose Unit Tests utilizing the describe-it syntax. It grasps the KISS (Keep It Simple, Stupid) structure rule. Kahlan requires requires at least PHP 5.5.
It has a small code base, it’s said to be about 10 times smaller than PHPUnit, and it has loads of features that provide us with an extensible and customizable testing workflow.
Selenium is an advanced testing framework that automates browsers. This implies it’s conceivable to compose User Acceptance Tests that examine the entire app as a whole.
Selenium is a robust tool that has its own WebDriver API that can drive a browser natively as though a real user would use it either locally or on a remote machine. Selenium is an excellent tool for testing more mature web applications.
Automated testing frameworks enable us to compose higher quality PHP code, and because of the popularity of the language we have numerous options, so we can pick the one that meets our development needs the best.
There’s something critical however that we generally need to remember. Automated testing might be powerful & amazing, but it can never substitute beta testing – tests done by genuine people will’s identity the future users of the application.
