Cypress is an open-source and free test automation tool, which can be used extensively in the long run. It is mainly used for front end test automation. This tool is mainly developed to solve the issues that the teams face, while automating an application.

Cypress helps to achieve the following −

Configure tests.

Configure tests.

Execute tests.

Identify errors (if any).

Selenium and Cypress are often compared in terms of their functionalities. However, Cypress is different in architecture and features. Moreover, it resolves some of the issues we face in Selenium.

Cypress is based on Javascript and executes tests within the browser. It helps to develop the tests which include −

Unit tests.

End to end tests.

Integration tests.

Features
The important features of Cypress are listed below −

Supports Test-Driven development.

Provides Dashboard services.

Efficient debugging with Developer Tools accompanied with generation of stack trace and errors.

Provides the screenshots for failed tests.

Not necessary to add waits to stop the execution for some time. By-default, the waits are applied, prior to executing the following step or assertion.

Able to monitor and control the characteristics of server response, functions, and timers, which are essentially needed for unit testing.

Check and manage network traffic.

Allows the multi-browser support.

In-built feature to capture videos of execution is available.

Can be integrated with continuous integration tools.

Page responsiveness with viewport sizing.

Reloads changes applied to tests by default.

Friendly Application Programming Interfaces (APIs) are available.

Test runner available, which allows the test execution straight from the User Interface (UI).

C++ is one of the world's most popular programming languages.

C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems.

C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs.

C++ is portable and can be used to develop applications that can be adapted to multiple platforms.

C++ is fun and easy to learn!

As C++ is close to C, C# and Java, it makes it easy for programmers to switch to C++ or vice versa.

A class is a user-defined blueprint or prototype from which objects are created. It represents the set of properties or methods that are common to all objects of one type. Using classes, you can create multiple objects with the same behavior instead of writing their code multiple times. This includes classes for objects occurring more than once in your code. In general, class declarations can include these components in order:

Modifiers: A class can be public or have default access (Refer to this for details).
Class name: The class name should begin with the initial letter capitalized by convention.
Superclass (if any): The name of the class’s parent (superclass), if any, preceded by the keyword extends. A class can only extend (subclass) one parent.
Interfaces (if any): A comma-separated list of interfaces implemented by the class, if any, preceded by the keyword implements. A class can implement more than one interface.
Body: The class body is surrounded by braces, { }.
An object is a basic unit of Object-Oriented Programming that represents real-life entities. A typical Java program creates many objects, which as you know, interact by invoking methods. The objects are what perform your code, they are the part of your code visible to the viewer/user. An object mainly consists of:

State: It is represented by the attributes of an object. It also reflects the properties of an object.
Behavior: It is represented by the methods of an object. It also reflects the response of an object to other objects.
Identity: It is a unique name given to an object that enables it to interact with other objects.
Method: A method is a collection of statements that perform some specific task and return the result to the caller. A method can perform some specific task without returning anything. Methods allow us to reuse the code without retyping it, which is why they are considered time savers. In Java, every method must be part of some class, which is different from languages like C, C++, and Python.
