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

	Tape https://github.com/substack/tape	Espec https://github.com/antonmi/espec
Programming language	JavaScript	Elixir
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	BDD driven testing framework for Elixir It is a testing framework written from scratch which is inspired by RSpec and the main idea is to close to its perfect DSL (Domain Specific Language)
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 Front-end components can be tested; there is also espec_phoenix for the Phoenix web framework
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 databases and server behaviour can be tested using Espec
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	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	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)	No Tape is a minimalistic framework that provides only essential features to make your assertions about your code	Yes It has a Built-in mocking functionality on top of Erlang 'meck' library
Grouping Allows organizing tests in groups	No Tape contains only the essential features for making assertions on your code	Yes By use of context blocksand tags functions
