Unit Testing

General info

Codeception is a full-stack testing framework for PHP

It is inspired by BDD and provides a way of writing acceptance, functional and even unit tests. It is powered by PHPUnit.

kotest is a powerful, elegant and flexible test framework for Kotlin, formerly known as kotlintest

Kotest has excellent support for data driven testing or table driven testing where it has the ability to quickly rerun the same test over and over with a predefined set of inputs and expected values
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

One is able to write acceptance tests which are used to look at functionality from a user's perspective. It is able to look at pages in browser (Chrome, Firefox or PhpBrowser)

Yes

You can test front-end components with kotest
Server-side
Allows testing the bahovior of a server-side code

Yes

It supports back-end tests, by writing functionaltests one can be able to test server behaviour

Yes

Yes, you can test back-end components with kotest
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

One can define a fixture and write the test with Codedeception, use the yii2-codedeceptionextention which will autoload fixtures for you

Yes

kotest contains fixtures, that is the setup / teardown functions
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

One can define group fixtures

Yes

kotest has group fixtures available
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

Codeception provides Codeception\Stub library for building mocks and stubs for tests

Yes

You can use a third party library like mockk to create mocks
Grouping
Allows organizing tests in groups

Yes

Codeception consists of three so-called “suites”: A “unit suite” for all unit tests, a “functional suite” for all functional tests, and an “acceptance suite” for all acceptance tests.

Yes

You can create test suites with kotest
