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.

JUnit is an open source Unit testing framework for java

JUnit is useful for developers to write and run repeatable tests. JUnit has been crucial in the development of test driven development and is partof the xUnit family of unit testing frameworks
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

It is 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

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 such as individual classes and functions that create the front-end
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

You can test classes and functions that compose the back-end such as database connections and so on
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

JUnit contains a setUp() method, which runs before every test invocation and a tearDown() method, which runs after every test method.
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

You can use setUp() and tearDown() inbuilt functions as 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.

N/A

You can use JUnit-quickcheck to generate test data
Licence
Licence type governing the use and redistribution of the software

MIT License

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

JUnit does not support mocking internally but you can use a mock framework like Mockito to generate mock objects.
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

In JUnit you can create a test suite that bundles a few unit test cases and runs them together. You use both @RunWith and @Suite annotation are used to run the suite test.
