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

• PHP 7.2+
• Composer
• phpdbg or Xdebug (only required for code coverage analysis)

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']]);

    });

});
