Mockery
Mockery is a simple yet flexible PHP mock object framework for use in unit testing with PHPUnit, PHPSpec or any other testing framework. Its core goal is to offer a test double framework with a succinct API capable of clearly defining all possible object operations and interactions using a human readable Domain Specific Language (DSL). -

Kahlan is a full-featured Unit & BDD test framework a la RSpec/JSpec which uses a describe-it syntax and moves testing in PHP one step forward.
Kahlan lets you stub or monkey patch your code directly like in Ruby or JavaScript without any required PECL-extensions.

Requirements
Main Features
- RSpec/JSpec syntax
- Code Coverage metrics (xdebug or phpdbg required)
- Handy stubbing system (mockery or prophecy are no longer needed)
- Set stubs on your class methods directly (i.e allows dynamic mocking)
- Ability to Monkey Patch your code (i.e. allows replacement of core functions/classes on the fly)
- Check called methods on your classes/instances
- Built-in Reporters (Terminal or HTML reporting through istanbul or lcov)
- Built-in Exporters (Coveralls, Code Climate, Scrutinizer, Clover)
- Extensible, customizable workflow
Syntax
<?php
describe("Example", function() {
it("makes an expectation", function() {
expect(true)->toBe(true);
});
it("expects methods to be called", function() {
$user = new User();
expect($user)->toReceive('save')->with(['validates' => false]);
$user->save(['validates' => false]);
});
it("stubs a function", function() {
allow('time')->toBeCalled()->andReturn(123);
$user = new User();
expect($user->save())->toBe(true)
expect($user->created)->toBe(123);
});
it("stubs a class", function() {
allow('PDO')->toReceive('prepare', 'fetchAll')->andReturn([['name' => 'bob']]);
$user = new User();
expect($user->all())->toBe([['name' => 'bob']]);
});
});
