Behat

Behat is a Behavior-driven Development (BDD) framework for PHP that allows developers to write tests using natural language. It is an open-source tool that aims to bridge the gap between stakeholders and technical teams by enabling them to collaborate and communicate effectively.

One of the key features of Behat is its focus on behavior-driven design, which emphasizes writing tests that describe the expected behavior of the application in terms of user stories or scenarios. These scenarios are written in Gherkin, a simple language that is easy to read and understand by both technical and non-technical stakeholders.

Behat supports various types of testing, including acceptance testing, functional testing, and integration testing. It provides a rich set of assertions and supports different testing frameworks, such as Selenium and Mink, which allow testing web applications in different browsers.

Behat can integrate well with various PHP frameworks such as Laravel, Symfony, and Yii. It also supports various plugins and extensions that allow developers to extend its functionality to meet their specific needs.

Pros

  • Open-source tool.
  • The use of Gherkin language gives good clarity and easy-to-read test cases.
  • Provides great HTML reports for test executions.
  • Supports execution in headless browsers like PhantomJS.
  • Works on Mac, Ubuntu, and Windows.
  • Has good community support and documentation.

Cons

  • Scripts are created in PHP, so QA needs to know PHP.
  • It supports only desktop browsers, and there is no support for mobile browsers. Read: Top 10 Desktop Testing Tools – [2025].
  • API testing is not supported by default.
  • Implementation time is lengthy, and test executions are not that fast.
  • Initial configuration and environment setup can be time-consuming.

PHPSpec

PHPSpec is designed to encourage Behavior Driven Development (BDD) and Object-Oriented Programming (OOP) practices. It is an open-source tool that helps developers write tests that describe the behavior of objects and classes in a clear way.

The emphasis on BDD design encourages developers to write tests that describe the code’s behavior in a natural language format. This makes it easier to understand the code’s expected behavior and helps ensure that the code is written to meet the desired behavior.

PHPSpec supports a number of built-in matchers that allow developers to write tests that describe the expected behavior of objects and classes. These matchers can be used to check that methods are called with the correct parameters, that properties are set to the correct values, and that exceptions are thrown when expected.

PHPSpec also supports the use of “mock objects,” which are objects that mimic the behavior of real objects but are designed for testing purposes. Mock objects can be used to simulate interactions between objects and help developers write tests that accurately reflect the behavior of the code.

Pros

  • PHPSpec is purpose-built for specifying and designing behavior of PHP objects, not just verifying functionality. So it is useful for BDD.
  • Supports object-oriented programming practices and encourages developers to write testable and maintainable code.
  • Integrates with various PHP frameworks, including Symfony, Laravel, and Zend, making it easier to write tests for code built on top of these frameworks.
  • Supports the use of mock objects, which can be used to simulate interactions between objects and help developers write tests that accurately reflect the behavior of the code.
  • Provides a range of built-in matchers, making it easier to write tests that accurately reflect the behavior of the code.

Cons

  • PHPSpec can have a steep learning curve, especially for developers who are not familiar with behavior-driven design or object-oriented programming practices.
  • PHPSpec may not be the best choice for testing legacy code or code that was not written with testing in mind.
  • Not be the best choice for testing applications that are heavily dependent on external systems, such as databases or APIs.
  • Since PHPSpec focuses on describing object behavior, a strong grasp of object-oriented principles is essential to use it effectively.

PHPUnit

PHPUnit is the most commonly used testing framework, mainly supporting unit and integration testing. Developed by Sebastian Bergmann, it’s considered a programmer-oriented framework. PHPUnit can also be used by developers for test-driven development. Though it can’t be used for End-to-End testing or API testing, this tool finds its place in Unit and Integration testing between Components. Almost every PHP framework uses PHPUnit for Unit testing. It supports execution via the command line and tests various controllers without extending it. PHPUnit can be installed by downloading the PHAR or added as a development-time dependency to your project using Composer. 

Pros

  • It’s an open-source testing tool that is maintained by the community, ensuring regular updates, bug fixes, and community-driven improvements.
  • It is widely used for unit testing on all PHP platforms and has become a cornerstone of Test-Driven Development (TDD) in PHP.
  • Used for analyzing the code coverage efficiently. Helping developers identify untested parts of the application and maintain high-quality codebases.
  • It provides different types of test reports, such as code coverage reports.
  • Test suites can be efficiently run via the command line or CI pipelines, making it a good fit for automation and continuous integration workflows.
  • PHPUnit supports custom test runners, annotations, and assertions, allowing teams to adapt tests to their specific needs.

Cons

  • PHPUnit is not designed for end-to-end (E2E), UI, or API testing. While there are workarounds with additional libraries, it’s not its core strength.
  • Unlike Behat or PHPSpec, PHPUnit does not follow a BDD-style syntax.
  • PHPUnit is developer-centric. It assumes coding knowledge and a technical understanding of the application internals, making it unsuitable for non-technical QA teams.
  • Writing tests for complex scenarios (mocking, stubs, exceptions) often requires significant boilerplate code, which may slow down the testing process or reduce maintainability.
  • Effective use of PHPUnit often requires developers to have a deep understanding of the application’s internal logic and architecture.

Codeception

Codeception is one of the most used testing frameworks that support unit testing, functional testing, and acceptance testing. It became more popular because of its high test execution speed, ease of use, and easy maintainability of the code base. It has default integration with PHP frameworks like Symfony2, Laravel4, Zend, Yii, etc. Codeception requires a version of PHP greater than 5 for installation; it also involves curl. Codeception can be installed by downloading the PHAR or manually downloading and installing it via Composer. Codeception follows a behavior-driven development approach. So, test cases can be written in the Gherkin language, similar to JBehave and Cucumber. It integrates with many CI tools like Jenkins and TeamCity. It provides various database modules supporting database testing. Codeception also has REST modules that help to test web services. 

Pros

  • Codeception supports Behavior-Driven Development (BDD) via Gherkin syntax. Tests are written in a human-readable format, making it easier for teams to understand test scenarios.
  • Codeception allows for unit, functional, and acceptance testing within a unified framework. This makes it suitable for full-stack testing.
  • It can be integrated with other frameworks like Selenium, and it seamlessly integrates with popular PHP frameworks like Symfony, Laravel, Yii, Zend, and more.
  • It provides detailed execution reports, including stack traces and screenshots (for failed UI tests), which improve debugging and test maintenance.
  • Designed with CLI execution in mind, it is highly compatible with automated CI/CD pipelines.

Cons

  • It supports the PHP language, so the QA person needs to have good knowledge of PHP.
  • Java and Ajax in the webpage can’t be tested using Codeception.
  • Though it can be used for unit testing, it’s volatile when it comes to code changes.
  • Acceptance tests using real browsers (e.g., via Selenium) tend to be slower, particularly in large test suites, and resource-intensive.
  • Functional tests that emulate browsers (without real rendering) may produce false positives, especially in JavaScript-heavy applications.
  • Codeception is limited to desktop browsers for UI automation. Native or hybrid mobile app testing requires external tools or complex configurations.

Wrapping Up

In summary, there are several testing frameworks available for PHP, each with its own strengths and weaknesses. Choosing the right framework will depend on the specific needs of your project and the experience and preferences of your development team. By selecting the right framework and following best testing practices, you can ensure that your PHP application is thoroughly tested and free of bugs and errors, leading to a better user experience and greater overall success of your project.
