General info

Kahlan is a full-featured BDD testing framework

It is a full-featured BDD testing framework that embraces the KISS (Keep It Simple, Stupid) design principle. Kahlan makes it possible to write unit tests using the 'describe-it' syntax and requires at least PHP 5.5

PHPUnit is a unit testing framework for the PHP programming language

PHPUnit is a programmer-oriented testing framework and is an instance of the xUnit architecture for unit testing frameworks.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

It's an instance of the xUnit architecture for unit testing frameworks
Client-side
Allows testing code execution on the client, such as a web browser

Yes

Kahlan allows you to test front-end components and behaviour easily

Yes

It can perform Unit tests and can test various front-end components and behaviours
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test individual back-end components using Kahlan

Yes

By performing unit tests on singular back-end components
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Fixtures can be defined by use of 'setUp()'method and cleaned using the 'tearDown()'method

Yes

By use of a setup code. The setup code consists of two Important template functions, the 'setUp()' function (called to create the objects to be tested) and 'tearDown()' function (called to cleanup the objects which you tested)
Group fixtures
Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests.

Yes

You can write group fixtures

Yes

It does support group fixtures
Generators
Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way.

Mocks
Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed)

Yes

With Kahlan's stubbing system you are able to set stubs (like mocks) directly to your class methods (dynamic mocking)

Yes

One of its main features is that PHPUnit comes with out of the box support for Mock objects
Grouping
Allows organizing tests in groups

Yes

Kahlan allows you to group tests syntactically using a closure syntax. It has describe and context methods for grouping

Yes

It allows grouping of tests and by using the @group annotation one can tag a test to belong to one or more groups
