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)

LightBDD is a BDD test framework that allows you to create easy to read and maintainable tests

LightBDD is a BDD test framework offering ability to write tests that are easy to read, easy to track during execution and are summarized in user friendly reports. It also allows developers to use all of the standard development tools to maintain them
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

No

No, but it is Integrated with xUnit frameworkslike NUnit, xUnit, MsTest.TestFramework and Fixie.
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

Yes

You can test front-end behaviour using lightBDD
Server-side
Allows testing the bahovior of a server-side code

Yes

databases and server behaviour can be tested using Espec

Yes

You can test back-end behaviour/functionality using lightBDD
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

N/A

Yes

Fixtures are available through the FeatureFixture class.
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

Yes
