General info

Doctest is an inbuilt test framework for Python

Doctest is a test framework that comes prepackaged with Python. It is a simple library with a functionality that makes it possible to search for pieces of text that look like interactive Python sessions and executes these sessions to see if they work exactly as shown.

tap-producing test harness for node and browsers.

Tape API is a small superset of the node core assert module
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

It does support xUnit output
Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can write tests for any part of your front-end code to test any component or functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

With tape you can test any back-end component, behaviour and functionality after all it supports TAP (Test Anything Protocol)
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

No

Lacks fixture management which can make writing tests harder

No

Tape contains only the essential features for making assertions on your code but there is a package called redtape that extends tape to give you beforeEach and afterEach functionality
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.

No

Lacks fixture management

No

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

No

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)

A good external library for using Mocks with Doctest is minimocks

No

Tape is a minimalistic framework that provides only essential features to make your assertions about your code
Grouping
Allows organizing tests in groups

Yes

One can group tests

No

Tape contains only the essential features for making assertions on your code
