Phony for Kahlan is a plugin for the Kahlan testing framework that provides general integration with the Phony mocking framework, as well as optional auto-wired test dependencies.
In other words, if a Kahlan test (or suite) requires a mock object, it can be defined to have a parameter with an appropriate type declaration, and it will automatically receive a mock of that type as an argument when run.
Stubs for callable
types, and "empty" values for other type declarations are
also supported.
Installation is only required when using the dependency injection features of the plugin. The plugin can be installed in the Kahlan configuration file like so:
<?php // kahlan-config.php
// disable monkey-patching for Phony classes
$this->commandLine()->set('exclude', ['Eloquent\Phony']);
// install the plugin once autoloading is available
Kahlan\Filter\Filters::apply($this, 'run', function (callable $chain) {
Eloquent\Phony\Kahlan\install();
return $chain();
});
Once the plugin is installed, any tests or suites that are defined with parameters will be supplied with matching arguments when run:
describe('Phony for Kahlan', function () {
it('Auto-wires test dependencies', function (PDO $db) {
expect($db)->toBeAnInstanceOf(PDO::class);
});
});
Phony for Kahlan supports automatic injection of mock objects. Because
Phony doesn't alter the interface of mocked objects, it is necessary to use
on()
to retrieve the mock handle in order to perform stubbing and
verification:
use function Eloquent\Phony\Kahlan\on;
describe('Phony for Kahlan', function () {
it('Supports stubbing', function (PDO $db) {
on($db)->exec->with('DELETE FROM users')->returns(111);
expect($db->exec('DELETE FROM users'))->toBe(111);
});
it('Supports verification', function (PDO $db) {
$db->exec('DROP TABLE users');
on($db)->exec->calledWith('DROP TABLE users');
});
});
Phony for Kahlan supports automatic injection of stubs for parameters with
a callable
type declaration:
describe('Phony for Kahlan', function () {
it('Supports callable stubs', function (callable $stub) {
$stub->with('a', 'b')->returns('c');
$stub('a', 'b');
$stub->calledWith('a', 'b')->firstCall()->returned('c');
});
});
The following table lists the supported type declarations, and the value supplied for each:
Parameter type | Supplied value |
---|---|
(none) | null |
bool |
false |
int |
0 |
float |
.0 |
string |
'' |
array |
[] |
iterable |
[] |
object |
(object) [] |
stdClass |
(object) [] |
callable |
stub() |
Closure |
function () {} |
Generator |
(function () {return; yield;})() |
When using a type declaration that is not listed above, the supplied value will be a mock of the specified type.
By necessity, the supplied value will not be wrapped in a mock handle. In
order to obtain a handle, simply use on()
:
use function Eloquent\Phony\Kahlan\on;
it('Example mock handle retrieval', function (ClassA $mock) {
$handle = on($mock);
});
