Programming language

PHP

Category

Unit Testing

Browser Automation

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

Puppeteer is a Node library which provides browser automation for chrome and chromium

Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium; It provides a high-level API to control Chromium or Chrome over the DevTools Protocol
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

Yes

By testing your PHP classes that run your front-end

Yes

Most things you can do manually in the browser can be done using puppeteer, therefore you can create a testing environment for your tests to run directly. You can test front-end functionality such as UI testing with puppeteer
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

No

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

N/A

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

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.

Yes

There are methods that act as generators

No

Licence
Licence type governing the use and redistribution of the software

Free

Apache License 2.0

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

No

Grouping
Allows organizing tests in groups

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

No
