Programming language

JavaScript

.NET

Category

Functional Testing, Asynchronous Testing

General info

Vows is a testing framework for NodeJS applications.

Vows supports Asynchronous BDD & continuous testing for two reasons first, reason is that node.js is asynchronous, and therefore our tests need to be, second,is to make test suites which target I/O libraries run much faster.

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
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

Yes

You can use Atata with xUnit frameworks
Client-side
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

Since it specifically tests Nodejs it tests back-end components and other server-side behaviours and functions

No

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

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.

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.
