Testing Fuel

Fuel uses PHPUnit for it's Unit Testing needs. It must be installed for the tests to run.

NOTE: No code will be accepted without tests written.

Running Tests

Running the unit tests is as simple as navigating to the root install folder on the command line and running the following:

$ phpunit

That's it! You can also tell it specific groups (which we will get into in minute) to run. For example to run only the core tests:

$ phpunit --group Core

Writing Tests

Where do they go?

All tests are to go in the tests folders inside their respective parent folder. For instance:

• App tests go in fuel/app/tests
• Core tests go in fuel/core/tests
• Package tests go in fuel/packages/package_name/tests

File / Class Naming

The Test class names should be in the form of Tests_Whatever.

Filenames should be all lower case and be the class name minus the "Tests_" part.

Some example names:

// Good
Tests_Arr in fuel/core/tests/arr.php
Tests_Image in fuel/core/tests/image.php
Tests_Fuel in fuel/core/tests/fuel.php

// Bad
Arrtests
Somestuff

Test Grouping

All tests inside the core folder must be in the core group. A classes test's should also be grouped together under the name of the class.

Here is an example of a core class test with proper DocBlocks:

/**
 * Arr class tests
 * 
 * @group Core
 * @group Arr
 */
class Tests_Arr extends TestCase {

	/**
	 * Tests Arr::element()
	 * 
	 * @test
	 */
	public function test_element()
	{
		// Test code here
	}
}

All App tests should be in the app group.

Namespaces

All core tests should be in the Fuel\Core namespace. This is so that we are sure we are testing the core classes, not any extensions that may be in app.

App tests can be in any namespace.

What class do I extend?

All tests should extend the Fuel\Core\TestCase class.

**NOTE: if you are in the Fuel\Core namespace you can leave off the Fuel\Core namespace and just extend TestCase.

Example

namespace Fuel\Core;

/**
 * Arr class tests
 * 
 * @group Core
 * @group Arr
 */
class Tests_Arr extends TestCase {

	/**
	 * Tests Arr::flatten_assoc()
	 * 
	 * @test
	 */
	public function test_flatten_assoc()
	{
		$people = array(
			array(
				"name" => "Jack",
				"age" => 21
			),
			array(
				"name" => "Jill",
				"age" => 23
			)
		);

		$expected = array(
			"0:name" => "Jack",
			"0:age" => 21,
			"1:name" => "Jill",
			"1:age" => 23
		);

		$output = Arr::flatten_assoc($people);
		$this->assertEquals($expected, $output);
	}

}
