Unit Testing

General info

Complete suite of testing facilities

Minitest is small, fast, and it aims to make tests clean and readable. It supports test-driven development (TDD), behavior-driven development (BDD), mocking, and benchmarking.

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.

Yes

MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD

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

No

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

You can test various back-end components

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

Minitest supports test fixture functions

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

Minitest has 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.

Yes

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

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

Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework

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

Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem

Yes

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