General info

Complete suite of testing facilities

Minitest is small, fast, and it aims to make tests clean and readable. It supports test-driven development (TDD), behavior-driven development (BDD), mocking, and benchmarking.

Atata is a C# / .NET test automation framework for web

Atata is an open source test framework that uses fluent object pattern. It consists of the following concepts: components (controls and page objects), attributes of the control search, settings attributes, triggers, verification attributes and methods
xUnit

Allows testing code execution on the client, such as a web browser

No

Yes

Atata is based on selenium and is used for browser automation. You can test various front-end functionalities and behaviours
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test various back-end components

No

Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Minitest supports test fixture functions

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.
