Unit Testing

General info

Cypress users are typically developers or QA engineers building web applications using modern JavaScript frameworks. This is the top tier UI automation framework which outsmarts Selenium based frameworks in most of the aspects!

Cypress enables you to write all types of tests: 1. End-to-end tests; 2. Integration tests; 3. Unit tests; 4. Cypress can test anything that runs in a browser; Apart from that Cypress provides the Dashboard facility for CI/CD

Kiwi is a Behavior Driven Development library for iOS development

The goal behind Kiwi is to provide a BDD library that is simple to setup and use, and create tests that are more readable than what is possible with the bundled test framework.
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.



Kiwi is an xUnit style framework
Allows testing code execution on the client, such as a web browser


This is the primary goal of Cypress, it tests anything that runs in a browser and works to build great user experience that is it tests the applications flow from beginning to end from a user's perspective. It is built to handle modern JavaScript frameworks especially well and also works equally well on older server rendered pages or applications


You can test front-end components with kiwi
Allows testing the bahovior of a server-side code


Although Cypress is not a general automation framework, nor is it a unit testing framework for your back-end services, It can test back-end behaviours for example using cy.task() command which provides a way for running Node code, so you can take actions necessary for your tests outside of the scope of Cypress


You can test back-end components with kiwi
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test


Cypress has inbuilt fixtures capabilities or example using the command 'cy.fixture(filePath)' loads a fixed set of data located in a file

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.


Cypress can create group fixtures using the 'cy.fixture' command


kiwi has a beforeEach(aBlock) which is run before every 'it' block in all enclosed contexts. Code that sets up the particular context should go here and afterEach(aBlock) which is run after every it block in all enclosed contexts
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.



through the beforeAll(aBlock) and afterAll(aBlock) functions.

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)


Cypress comes built in with the ability to stub and spy with cy.stub(), cy.spy(), It also automatically bundles 'sinon', 'lolex' and 'sinon-chai' which all work to give Cypress mocking capabilities


Kiwi has inbuilt support for stubs and mocks,including null mocks, class mocks, protocol mocks
Allows organizing tests in groups


Cypress allows you to configure tests into groups however there is no way currently to run the groups


Kiwi uses the block syntax in iOS to define groups of assertions and share setup state between collections of tests
