Tape vs Lettuce comparison of testing frameworks
What are the differences between Tape and Lettuce?

	Tape https://github.com/substack/tape	Lettuce https://pypi.org/project/lettuce/
Programming language	JavaScript	Python
Category	Unit Testing, Intergration Testing	Unit Testing, Acceptance Testing
General info	tap-producing test harness for node and browsers. Tape API is a small superset of the node core assert module	Lettuce is a BDD testing tool for Python Lettuce is a testing tool for Python which is inspired by Ruby's Cucumber that supports Gherkin. It can execute plain-text functional descriptions as automated tests for Python projects just like Cucumber does for Ruby
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	Yes It does support xUnit output	No However It can generate xml results for behaviour tests xUnit style
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 By integrating Lettuce with Selenium’s Python bindings, you have a robust framework for testing Django applications. It can test front-end 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 Lettuce can test various server and database behaviours and interactions
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	N/A
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	N/A
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 third party library
Licence Licence type governing the use and redistribution of the software	MIT License	Unknown
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	By adding the lettuce-tools library one has access to the Mock module to implement a configurable http REST mock.
Grouping Allows organizing tests in groups	No Tape contains only the essential features for making assertions on your code	Yes It allows grouping of tests
