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

	Lettuce https://pypi.org/project/lettuce/	Robot Framework https://robotframework.org/
Programming language	Python	Python
Category	Unit Testing, Acceptance Testing	Acceptance Testing
General info	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	Robot is a Python framework used for acceptance/functional testing Robot is an automated test framework which has a simple plain text syntax and can be extended easily with Python or Java libraries. It can run on the .net-based IronPython and on Jython which is Java based.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No However It can generate xml results for behaviour tests xUnit style	No
Client-side Allows testing code execution on the client, such as a web browser	Yes By integrating Lettuce with Selenium’s Python bindings, you have a robust framework for testing Django applications. It can test front-end behaviour	Yes Robot has a rich library and can also be easily integrated with Selenium for browser automation to test front-end components
Server-side Allows testing the bahovior of a server-side code	Yes Lettuce can test various server and database behaviours and interactions	Yes Robot can be used for back-end tests as well
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	N/A	There is no inbuilt way to work with fixtures in Robot however it can integrate with unittest and use fixtures that way
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	By integrating with unittest
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 By using a third party library	Yes Robot has a library called the Robot Framework Faker library. It contains 147 keywords used for generating random test data
Licence Licence type governing the use and redistribution of the software	Unknown	Apache License 2.0
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)	By adding the lettuce-tools library one has access to the Mock module to implement a configurable http REST mock.	Yes Robot can access Python's mock library for mocking
Grouping Allows organizing tests in groups	Yes It allows grouping of tests	Yes One can create a test suite with Robot
