Unit Testing

General info

Intern is minimal test system for JavaScript designed to write and run consistent.

Intern is a complete test system for JavaScript designed to help you write and run consistent, high-quality test cases for your JavaScript libraries and applications. Using Intern we can write tests in JavaScript and TypeScript using any style like TDD, and BDD. Intern can run unit tests in most browsers that support ECMAScript

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

Intern is a complete test system for JavaScript It Runs in the browser and can test any front-end component and functionality

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

Since it is a complete testing system that can test any type of JavaScript code, it can test server-side behaviour and components as well

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

N/A

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.

N/A

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)

Intern uses the Dojo Toolkit’s AMD loader. To mock, you should be able to just use the standard AMD 'map' feature, else you can use third party libraries like sinon.js

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

You can group tests into Suites which may be specified as file paths or using glob expressions, there is typically one top-level suite per module.

Yes

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