What are the differences between Lens and Tape?

	Lens https://github.com/spencer-mortensen/lens	Tape https://github.com/substack/tape
Programming language	PHP	JavaScript
Category	Unit Testing	Unit Testing, Intergration Testing
General info	Lens is a unit-testing framework for PHP Lens is a unit-testing framework for PHP that needs no assertions	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.	N/A	Yes It does support xUnit output
Client-side Allows testing code execution on the client, such as a web browser	Yes It can test front end components	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 It can test back-end behaviour	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	N/A	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.	N/A	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
Licence Licence type governing the use and redistribution of the software	N/A	MIT License
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)	N/A	No Tape is a minimalistic framework that provides only essential features to make your assertions about your code
Grouping Allows organizing tests in groups	N/A	No Tape contains only the essential features for making assertions on your code
