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

	Peridot http://peridot-php.github.io/	Lettuce https://pypi.org/project/lettuce/
Programming language	PHP	Python
Category	Unit Testing	Unit Testing, Acceptance Testing
General info	Peridot is a lightweight, extensible testing framework for PHP It features an event-driven architecture that allows testers to easily customize the framework via plugins and reporters, and uses the 'describe-it', syntax making the testing language clear and readable	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.	No	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 Front-end components can be tested with Peridot	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 Back-end componets and behaviours can be tested as small units	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	Yes Peridot has several methods that allow one to create and define fixtures	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.	Yes There are methods to create group fixtures in Peridot	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.	N/A	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)	Peridot does not include mocking out of the box but there are some great tools like 'Mockery' and 'Prophecy' which Peridot intergrates very well with	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	Yes By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.	Yes It allows grouping of tests
