Codedeception vs unittest2 comparison of testing frameworks
What are the differences between Codedeception and unittest2?

	Codedeception https://codeception.com/	unittest2 https://pypi.org/project/unittest2/
Programming language	PHP	Python
Category	Unit Testing, Acceptance Testing/Functional Testing	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.	Unittest2 is a newer version on the inbuilt unit testing framework unittest To use o use unittest2 instead of unittest, simply replace 'import unittest' with 'import unittest2'. It has many new features such as: - addCleanups for better resource management; -many new assert methods; - assertRaises as context manager, with access to the exception afterwards; - test discovery and new command line options (including failfast and better handling of ctrl-C during test runs); - class and module level fixtures: setUpClass, tearDownClass, setUpModule, tearDownModule; -test skipping and expected failures and many more improvements on the API and bug fixes
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	Yes unittest2 is a newer version of unittest which is an xUnit style framework for Python.
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 Front-end functionality and behaviour can be tested by unittest2. function by function
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 We can write tests with unittest2 to test each function for server-side behaviour
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 By use of the 'setUp()' function which is called to prepare the test fixture
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 unittest2 allows you to group your initialization code buy use of the 'setUp()' function and clean up code with a 'tearDown()' function
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	Yes unittest2 contains generator methods in the module 'unittest.TestCase'
Licence Licence type governing the use and redistribution of the software	MIT License	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	Yes Mocks are available from the library unittest.mock which allows you to replace parts of your system under test with 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 One can build suites either manually or use test discovery to build the suite automatically by scanning a directory
