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

	Espec https://github.com/antonmi/espec	Doctest https://docs.Python.org/2/library/doctest.html
Programming language	Elixir	Python
Category	Unit Testing	Unit Testing
General info	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)	Doctest is an inbuilt test framework for Python Doctest is a test framework that comes prepackaged with Python. It is a simple library with a functionality that makes it possible to search for pieces of text that look like interactive Python sessions and executes these sessions to see if they work exactly as shown.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	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 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	N/A	No Lacks fixture management which can make writing tests harder
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 Lacks fixture management
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	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)	Yes It has a Built-in mocking functionality on top of Erlang 'meck' library	A good external library for using Mocks with Doctest is minimocks
Grouping Allows organizing tests in groups	Yes By use of context blocksand tags functions	Yes One can group tests
