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.

Peridot is a lightweight, extensible testing framework for PHP

It features an event-driven architecture that allows testers to easily customize the framework via plugins and reporters, and uses the 'describe-it', syntax making the testing language clear and readable
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

No

Front-end components can be tested with Peridot
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

Yes

Back-end componets and behaviours can be tested as small units
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

No

Yes

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)

Peridot does not include mocking out of the box but there are some great tools like 'Mockery' and 'Prophecy' which Peridot intergrates very well with
Grouping
Allows organizing tests in groups

Yes

By use of describe and context blocks and it has a Runner which is responsible for running a given Suite.
