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

	Espec https://github.com/antonmi/espec	NBi http://www.nbi.io/
Programming language	Elixir	.NET
Category	Unit Testing	Integration Testing, Unit Testing, Acceptance 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)	NBi is an open-source framework for testing Business Intelligence solutions or validating data quality. NBi helps you to create tests targeting your databases, cubes, etls and reports. Tests are written in xml using an intuitive syntax therefore thereis no need of any development language. Nbi tests target databases, cubes, etls and reports
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	No
Server-side Allows testing the bahovior of a server-side code	Yes databases and server behaviour can be tested using Espec	Yes Nbi tests Business intelligence software which retrieve, analyze, transform and report data therefore it targets databases, cubes, etls and reports and you can natively connect to any database supporting OleDb or ODBC connection
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
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	N/A
Licence Licence type governing the use and redistribution of the software	MIT License	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)	Yes It has a Built-in mocking functionality on top of Erlang 'meck' library	Yes You can create your own mock objects
Grouping Allows organizing tests in groups	Yes By use of context blocksand tags functions	Yes Yes, Nbi comes with a solution to automate, as much as possible, the creation of the test-suites through its user interface, named GenBI
