Acceptance Testing

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.

Gauge is a light-weight cross-platform test automation tool for writing acceptance tests.

Gauge is a free and open source framework for writing and running acceptance tests. Some of its key features include: -Simple, flexible and rich syntax based on Markdown.; -Consistent cross platform/language support for writing test code.; -A modular architecture with plugins support.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

MiniTest is an xUnit style framework in that is has assertion functions in the style of xUnit/TDD

No

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

No

Yes

You can test front-end behaviour by creating testing specifications to test front-end behaviour
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test various back-end components

Yes

You can test back-end behaviour by creating testing specifications to test back-end behaviour
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.

Yes

Minitest has group fixtures

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

Mocking is available through the Minitest::Mock class which is a simple and clean mock object framework

Yes

You can create mocks using third party libraries like moq
Grouping
Allows organizing tests in groups

Yes

Allows grouping by nested Ruby classes. RSpec-like "context" method is available for spec syntax through the minitest-spec-context extension gem

Yes

You can create test suites with Gauge which can be run using multiple parameters.
