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


Programming language




Unit Testing

General info

Atata is a C# / .NET test automation framework for web

Atata is an open source test framework that uses fluent object pattern. It consists of the following concepts: components (controls and page objects), attributes of the control search, settings attributes, triggers, verification attributes and methods

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
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.


You can use Atata with xUnit frameworks


unittest2 is a newer version of unittest which is an xUnit style framework for Python.
Allows testing code execution on the client, such as a web browser


Atata is based on selenium and is used for browser automation. You can test various front-end functionalities and behaviours


Front-end functionality and behaviour can be tested by unittest2. function by function
Allows testing the bahovior of a server-side code



We can write tests with unittest2 to test each function for server-side behaviour
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


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.


unittest2 allows you to group your initialization code buy use of the 'setUp()' function and clean up code with a 'tearDown()' function
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.


unittest2 contains generator methods in the module 'unittest.TestCase'

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)


Mocks are available from the library unittest.mock which allows you to replace parts of your system under test with mock objects
Allows organizing tests in groups


One can build suites either manually or use test discovery to build the suite automatically by scanning a directory
