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)

Atoum is a unit testing framework specific to the PHP language

Atoum is similar to SimpleTest and is designed to be implemented rapidly, simplify test development and allow for writing reliable, readable, and clear unit tests
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

Yes

Autom can perform unit tests on various front-end components and behaviours
Server-side
Allows testing the bahovior of a server-side code

Yes

databases and server behaviour can be tested using Espec

Yes

Autom can perform unit tests on servers/back-end components
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

By using the 'given()' method to setup your environment
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

By using the 'given()' method to setup your environments
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.

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

By use of autom mocks which are decoupled and easier to maintain
Grouping
Allows organizing tests in groups

Yes

By use of context blocksand tags functions
