General info

Mocha is a widely used JavaScript test framework for Node.js

Mocha is a simple, flexible and the one of the widely adopted JS test framework. Mocha usually runs tests serially which enables the accurate reporting. Also it's useful for asynchronous testing, and provides various king of test reports. Spec is default test reporter for mocha, there are many test reports like Nyan, Dot matrix, Tap, Landing strip, List and Progress. Mocha is being used with many other test frameworks like Selenium WebDriver,, wd and Cypress

SimpleTest is a unit test and web test framework for PHP

It has JWebUnit style functionality and support for SSL, forms, frames, proxies and basic authentication
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.


It has an XUnit reporter available which outputs an XUnit-compatible XML document, often applicable in CI servers.


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


Mocha Runs in the browser and is used widely to test front-end components and functionality. It can test various DOM elements, front-end functions and so on.


With SimpleTest common but fiddly PHP tasks, such as logging into a site, can be tested easily
Allows testing the bahovior of a server-side code


Mocha provides convenient ways of testing the Node server.It works well with Chai (an assertion library) where it provides the environment for writing server-side tests while we write the tests with Chai


Server-side behaviour can be tested by writing simple unit tests to test functionality and behaviour of single components.
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Mocha provides the hooks before(), after(), beforeEach(), and afterEach() to set up preconditions and clean up after your tests


It can import fixtures using a mixin like 'given()' method
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.


Mocha allows grouping of fixtures


It allows grouping of fixtures
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.


Simpletest has support for generators

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)

Provides Mocking capabilities through third party libraries like sinon.js, simple-mock and nock


It allows for one to build Mock objects.To create a mock version of a class we need to include the mock object library and run the generator. This will create a clone class which we use to create new instances(objects) in our test cases.
Allows organizing tests in groups


Grouping is supported and is accomplished by the using a nested 'describe()'


There are several ways of grouping tests; one is to simply place multiple test cases into a single file, another is to mark any base test cases that should not be run as abstract, Simpletest gives you a couple of options
