What are the differences between Tape and stestr?

Tape

stestr

https://pypi.org/project/stestr/
Programming language

JavaScript

Python

Category

Unit Testing, Intergration Testing

Unit Testing

General info

tap-producing test harness for node and browsers.

Tape API is a small superset of the node core assert module

stestr is a Python test runner designed to execute unittest test suites

stestr executes unittest test suites by using multiple processes to split up execution of a test suite then stores a history of all test runs to help in debugging failures and optimizing the scheduler to improve speed.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It does support xUnit output

No

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

Yes

Stestr being a test runner that runs unittest tests, it can test fron-tend functionality and behaviour.
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)

Yes

Stestr being a test runner that runs unittest tests, it can run back-end tests for functionality and behaviour.
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

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

Yes

By use of a third party library like 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.

No

By use of a third party library like Fixture
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.

No

Yes

By using a library like test-generator

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)

No

Tape is a minimalistic framework that provides only essential features to make your assertions about your code

N/A

Grouping
Allows organizing tests in groups

No

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