Difference between Cucumber and Selenium

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

Cucumber

It is a Behavior Driven Development tool used to develop test cases for the behavior of software's functionality. It plays a supporting role in automated testing.

In other words, cucumber is a software tool used by the testers to develop test cases for the testing of behavior of the software.

Cucumber tool makes the test scripts very easy, because the test cases are written in a simple English text, which anybody can understand without any technical knowledge. This simple English text is called the Gherkin language.

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

Cucumber tool can be used along with various testing tools such as Watir, Selenium, and Capybara, etc.

Cucumber tool was originally 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, PHP, Net, Python, Perl, etc. with various implementations. In Java, it supports native JUnit.

Selenium

Selenium is one of the most widely used open-source Web UI (User Interface) automation testing suite. Selenium supports automation across different browsers, platforms, and programming languages.

Selenium can be easily deployed on platforms such as Windows, Linux, Solaris, and Macintosh. Moreover, it supports OS (Operating System) for mobile applications like iOS, windows, mobile, and android.

Selenium supports a variety of programming languages through the use of drivers specific to each language. Languages supported by Selenium include C#, Java, Perl, PHP, Python and Ruby. Currently, Selenium Web driver is most popular with Java and C#. Selenium test scripts can be coded in any of the supported programming languages and can be run directly in most modern web browsers. Browsers supported by Selenium include Internet Explorer, Mozilla Firefox, Google Chrome, and Safari.

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

Cucumber vs Selenium
Cucumber Selenium
It is a Behavior Driven Development tool used to develop test cases for the behavior of software's functionality. It is an automated testing tool.
Cucumber is a free or open-source BDD (Behavior Driven Development) tool. Selenium is also a free or open-source testing tool.
Cucumber is a BDD supported tool. Selenium is a both Functional and Performance (Selenium Grid) testing tool.
Cucumber framework supports many languages, such as Java, Scala, Groovy, etc. beyond Ruby. Selenium also supports many languages, such as Java, .Net, etc.
Cucumber includes both testers and developers to write automation steps. Like Cucumber, Selenium also includes both testers and developers to write automation steps.
Cucumber is used to test only web applications. Like Cucumber, Selenium also used to test only web applications.
Cucumber testing is less reliable as compared to Selenium and QTP. The process of Selenium makes testing more reliable and dependable.
Cucumber works very fast in Plugin. Selenium works slower in Plugin than Cucumber.
