General info

Sleipnir is a BDD-style framework for Swift

Sleipnir is a pure Swift BDD testing framework inspired by cedar, that is not dependent on NSObject, and does not use XCTest. Sleipnir has nice command line output and support for custom test reporters and other features, like seeded random tests invocation, focused and excluded examples/groups

JS Unit test framework, BDD based for Node.JS applications used with Angular.JS web applications and also paired with 'Karma' task runner

It's a BDD (Behavior Driven Development) test framework for JavaScript especially designed for manual QAs to understand the automation tests. It does not depend on the any JavaScript framework or browser. So it's very well suited for Node.js projects and websites
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

N/A

No

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

Yes

You can test front-end behaviour by defining specifications for classes, objects and functions

Yes

Jasmine works well in and with browsers to test client-side components and functionality
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test back-end behaviour by defining specifications for classes, objects and functions in the back-end

Yes

Jasmine works with NodeJs to test its back-end components and behaviour
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Fixtures are available by using beforeEach{ } and afterEach{ } to setup the test parameters

Yes

By using 'jasmine-fixture' which can help write specs that interact with the DOM making it easier to injectHTML fixtures
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

Group fixtures are available through the beforeAll{} and afterAll{} blocks to setup group fixtures

N/A

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

Yes, developers can create mock objects with sleipnir using a third party library like Cuckoo.

By using a a plugin called jasmine-ajax that allows ajax calls to be mocked out in tests
Grouping
Allows organizing tests in groups

Yes

You can declare example groups with Slepnir

Yes

Using the describe function which is for grouping related tests, typically each test file has one at the top level.
