FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

TestTube: Unit Testing Framework
TestTube is a lightweight and extensible unit testing framework for PHP. Originally built to support the Xpression library, its design prioritizes flexibility, making it suitable for small to medium-sized projects.
Requirements
- Composer must be installed.
Installation
-
Create a new TestTube project (you can replace 'example' with your desired directory name):
-
Configure
composer.jsonto autoload the PHP libraries you want to test: - Regenerate autoload files:
Writing Your First Test
Let’s create a simple test for a Calculator class.
-
Inside the
testsdirectory, create a folder to group your test files (e.g.,demo). Create a PHP file for your tests, such ascalculator.php: - Define a
bootmethod to instantiate the object(s) required for your tests:
If more than one object is required, return an array containing the objects:
-
Create a test method. Each test method should take as parameters the objects returned by the
bootmethod. By default, test method names must be camel-cased and start with 'test': -
Define the body of the test, using an appropriate
assertmethod: - Run your tests from the project's root directory
Example Output:
- Modify the expected value to simulate a failed test:
Re-running the tests will produce:
Once a test file contains more than one test, the output will show both the filename and method name to help pinpoint failures.
Advanced Features
Assertions
TestTube includes several assert methods:
assertEquals($expected, $actual, $failureMessage = null)assertTrue($boolean, $failureMessage = null)assertFalse($boolean, $failureMessage = null)
The $failureMessage parameter is optional, and a default message will be generated if omitted.
Custom Test Method Names
If you need non-standard test method names, you can declare them using the $useMethods property. You can also disable automatic detection of test methods starting with "test" by setting $useTestMethods to false:
Templates
To follow the DRY (Don't Repeat Yourself) principle, TestTube allows you to extend from templates stored in the templates directory. For example, to share a boot method across multiple test files:
-
Create a reusable template:
- In your test file, extend this template:
The setup Method
The setup method helps to maintain a separation of concerns between object creation and configuration. It allows for any further customisation of the objects returned by the boot method before each test. Like test methods, it must accept each object returned by boot as a parameter:
