Simple unit test and mocking framework
Unit Test & Mocking Framework for PHP., (*1)
Create mocks and stubs on the fly with the Mock Framework and Unit test your code with the Unit Test framework. This all comes in one pakcage, ready and easy to be used!, (*2)
A simple unit test and mocking framework., (*3)
Simply install the testsuite through composer:, (*4)
/> composer require annexus/testsuite
Now create a folder in your project that will contain all your tests. In that folder create a simple test class (see description below for a simple example). Note, the filename MUST be the same as your class name. Example:, (*5)
File: SomeTest.php
You should then name your class like so: class SomeTest { }, (*6)
Now you're ready to run your test. The command from console should look like this:, (*7)
/> php [path to TestSuite.phar] [path to folder containing tests]
Or, if you want to load a bootstrap file like composers "autoload.php" or your custom file:, (*8)
/> php --bootstrap [path to bootstrap file] [path to TestSuite.phar] [path to folder containing tests]
Example:, (*9)
/> php /var/www/vendor/annexus/testsuite/TestSuite.phar /var/www/tests
Or with bootstrap file, (*10)
/> php --bootstrap /var/www/vendor/autoload.php /var/www/vendor/annexus/testsuite/TestSuite.phar /var/www/tests
A Unit Test class (or Test Case) can have any name and must always extend from CFUnitTestCase and therfor this class must be included. It is important that the class name of the Unit Test is the same as the file name., (*11)
A test method MUST have Test_ as prefix. All other methods will not be run by the Test Suite., (*12)
class ExampleTestCase extends CFUnitTestCase
{
public function Test_A_simple_assertion()
{
$this->assert(5)->should()->be(5)->and()->beGreaterThan(2);
}
}
Additionally a Test Case can also have one of the following methods:, (*13)
public function setUp() - This is run before each test method is executed public functin tearDown() - This is run at the end of each test method public function setUpBeforeClass() - This is run before any test method is executed public function tearDownAfterClass() - This is run after all test methods are executed
An assertion can be made in a fluent way. The following assertions are supported., (*14)
// Mixed assertion
$this->assert($string)->Should()->be('something');
$this->assert($array)->Should()->be($someOtherArray);
$this->assert($bool)->Should()->notBe(true);
// Type checking
$this->assert($string)->Should()->beAString();
$this->assert($object)->Should()->beAnObject();
$this->assert($array)->Should()->beAnArray();
$this->assert($int)->Should()->beAnInt();
$this->assert($float)->Should()->beAFloat();
$this->assert($bool)->Should()->beTrue();
$this->assert($bool)->Should()->beFalse();
$this->assert($mixed)->Should()->NotBeNull();
$this->assert($mixed)->Should()->beNull()
$this->assert($string)->Should()->beEmpty();
$this->assert($string)->Should()->NotBeEmpty();
// String specific assertions
$this->assert($string)->should()->haveLength(5);
$this->assert($string)->should()->beEquivalentTo($someString); // Case insensitive compare
$this->assert($string)->should()->startsWith($someString); // Case sensitive compare
$this->assert($string)->should()->startsWithEquivalent($someString); // Case insensitive compare
$this->assert($string)->should()->endWith($someString); // Case sensitive compare
$this->assert($string)->should()->endWithEquivalent($someString); // Case insensitive compare
$this->assert($string)->should()->contain($someText);
$this->assert($string)->should()->notContain($someText);
$this->assert($string)->should()->containEquivalentOf($someString); // Case insensitive compare (also on array values)
$this->assert($string)->should()->notContainEquivalentOf($someString); // Case insensitive compare (also on array values)
// Array specific assertions
$this->assert($array)->should()->contain($someOtherArray); // On intersect = success
$this->assert($array)->should()->notContain($someOtherArray); // When not intersects = success
$this->assert($array)->should()->notContainNull();
// Number assertions
$this->assert($int)->should()->beGreaterOrEqualTo($number);
$this->assert($int)->should()->beGreaterThan($number);
$this->assert($int)->should()->beLessOrEqualTo($number);
$this->assert($int)->should()->beLessThan($number);
$this->assert($int)->should()->bePositive();
$this->assert($int)->should()->beNegative();
$this->assert($int)->should()->beInRange($min, $max); //min=1, max=2 and given=2 will result in success
// Date assertions
$this->assert($datetime)->should()->beAfter($someDatetime);
$this->assert($datetime)->should()->beBefore($someDatetime);
$this->assert($datetime)->should()->beOnOrAfter($someDatetime);
$this->assert($datetime)->should()->beOnOrBefore($someDatetime);
// Throwable assertions
$this->assert()->should()->shouldThrow($func); Give the method that should be executed as an anonymous function to this method.
$this->assert()->should()->shouldThrow($func)->WithMessage('Exact exception message');
$this->assert()->should()->shouldThrow($func)->WithMessage('* psrtial message'); // The asterisk acts as a wild card. Can be used at the beginning, end or both sides of the string
$this->assert()->should()->shouldNotThrow($func);
// Extending assertions with "And()"
$this->assert($string)->should()->beAString()->and()->HaveLength(5);
When you want to mock an object then you must first include the class CFMock/CFMock.php. Now mocking will be a breeze., (*15)
You create a mocked version of an object like this:, (*16)
$mock = new Mock::create( 'DummyClass' );
$mock->aCallTo('SomeMethod')->returns('some value');
// Or even namespaced classes can be loaded:
$mock = new Mock::create( '\Some\Namespace\DummyClass' );
Calls can then be made on the $mock object., (*17)
The mock framework also comes with a few assertions., (*18)
expectCallCount(2); // Expects that many calls to a certain method expectMinimumCallCount(2); // Expects at least that many calls to a certain method expectMaximumCallCount(2); // Expects a maximum of 2 calls to a method, less is fine as well expectNever(); // A certain method should never be called expectOnce(); // Only a single call is expected to be made to a certain method
A typical setup for a mock test could be this:, (*19)
$mock = new Mock::create( 'DummyClass' );
$mock->aCallTo('SomeMethod')->returns('some value')->expectOnce();
$mock->someMethod('message'); // Will return the string: 'some value'
This is obviously not a real world example, but it should illustrate the idea., (*20)
When you have created your unit tests then these can easily be run from the browser. Simply browse to "vendor/testsuite/annexus/Unit/Runners/WebWebRunner.php", (*21)
In there you can simply hit the "Run Tests" button or select the tests you want to run., (*22)
You can also run tests through command line:, (*23)
There are two ways to run tests:, (*24)
Notice that "--bootstrap" MUST come as the first argument. That command could be useful for example to load the "autoload.php" file that comes with composer. So you have access to all your classes in your Unit Tests., (*25)
