AVA

Programming language

PHP

JavaScript

Category

Unit Testing

Unit Testing, Intergration Testing

General info

PhpSpec is a testing tool based on the concept of emergent design using specification

PhpSpec is a tool to use at the spec level or SpecBDD, a type of BDD; It's process generates code for you and guides you through the SpecBDD process through the command line

Futuristic, new, fast and concurrent JavaScript test runner with simple test syntax

AVA is a test runner for Node.js with a concise API, detailed error output. JS is a single-threaded but Node.JS is a parallel due to it's async behaviour. Ava leverages that and it can run tests concurrently
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

No

However Ava supports the TAP format which allows us to use the tap-xunit reporter to produce xUnit (JUnit) XML
Client-side
Allows testing code execution on the client, such as a web browser

Yes

By testing your PHP classes that run your front-end

Yes

You can write tests for the DOM with Ava, testing front-end components is easy with Ava
Server-side
Allows testing the bahovior of a server-side code

Yes

You can use PHPSpec to test your PHP classes that run your back-end

Yes

Ava utilizes the async I/O nature of Node and runs concurrent tests on NodeJs applications' back-endsA node server can have its endpoints tested with Ava
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

You can define fixtures

Yes

Using Ava's ava-fixture library it supports 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

You can define group fixtures

Yes

Ava has support for 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.

Yes

There are methods that act as generators

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

It has built in support for Mocks

AVA has no mocking built in, to mock functions you can use third party libraries like Sinon.js.
Grouping
Allows organizing tests in groups

In PHPspec, you can group specification files by a certain namespace in a suite

No

There is no support for grouping tests
