Difference between Cucumber and QTP

Before knowing the differences between cucumber and QTP first, let's take a quick introduction of these.

Cucumber

Cucumber is a Behavior Driven Development tool used by the testers to develop test cases for the testing of behavior of the software.

Cucumber uses Gherkin language to write the test scripts. Gherkin language is a simple English text language hence anybody can understand it without any technical knowledge.

It allows developers, testers, business analysts, etc. to automate functional verification and validation in an easily readable and understandable format (e.g., plain English).

Cucumber tool was initially written in the "Ruby" programming language. It was exclusively used only for testing of Ruby as a complement to the RSpec BDD framework.

But now, Cucumber supports a variety of different programming languages including Java, JavaScript, Python, PHP, Net, Perl, etc. with various implementations. In Java, it supports native JUnit.

QTP

QTP stands for Quick Test Professional. It is a software tool which helps testers in performing automated functional testing. In QTP, the automated functional testing is done without any monitoring and only after the completion of test script development. QTP is best suited for regression testing of the software applications.

QTP uses Visual Basic Scripting (VBScript) language for automation testing of the software applications.

VBScript is not an object-oriented language, but it is an object-based language.

We don't need to install the Scripting Engine exclusively, as it is already available as a part of the Windows Operating System (OS).

The Current version of VBScript is 5.8, which is a part of Windows 7.

Now, let's have a look at fundamental differences between Cucumber and QTP:

Cucumber	QTP
It is a Behavior Driven Development tool used to develop test cases for the behavior of software's functionality.	It is an automated functional testing tool.
Cucumber is best suited for the development of the web application's behavior.	QTP is best suited for regression testing of the applications.
Cucumber is a free or open-source BDD (Behavior Driven Development) tool.	QTP (Quick Test Professional) is an expensive paid testing tool.
Cucumber is a supported BDD testing tool.	QTP is an Automation testing tool which offers automation testing for Functional and Regression testing.
Cucumber framework supports many languages such as Java, Scala, Groovy, etc. beyond Ruby.	QTP supports only VB script.
Cucumber includes both testers and developers to write automation steps.	QTP includes only testers to Write automation steps.
Cucumber is used to test only web applications.	QTP is used to test the web, desktop, and any client-server application.
Cucumber testing is less reliable as compared to selenium and QTP.	It is more reliable than Cucumber.
Cucumber works very fast in Plugin.	QTP works slower in Plugin as compared to Cucumber and Selenium.
