Cucumber – Best BDD Framework for Selenium

Cucumber – Best BDD Framework for Selenium

One of the top reasons why developers prefer to use frameworks like Selenium is that it allows them to place the code and data in different places, which makes the program reusable and more efficient.

Cucumber is a Behaviour Driven Development (BDD) framework that can be used to tests your codes on Selenium. This blog will explore the reasons why Cucumber makes the best BDD framework for Selenium.

Selenium Framework

Selenium framework makes programs more effective as it places codes and data in different grids of the framework. Also, it breaks the code into smaller units that makes it easy for testing each function of the code. Selenium has three different kinds of frameworks – data driven, keyword driven and hybrid.

Cucumber

Cucumber is a testing tool that is built on Behavior Driven Development (BDD) framework. This software tool supports various programming languages such as Python, .NET, PHP, Perl, Java and more. It can be used to write acceptance tests that check functional validity of the codes and system behavior.

Cucumber is the preferred tool for creating acceptance tests as its focus is on the user-experience. Moreover, its operations can be easily understood by business stakeholders and decision makers who don’t come from a coding background. As it allows for reuse of codes, testing can be completed quickly and effectively.

Cucumber can be integrated with Selenium in just three steps:

  • Creating and implementing feature file
  • Creating Test runner file and executing the script
  • Creating Step Definition and running the acceptance test

Why is Cucumber the best BDD framework for Selenium?

Readable and understandable by all

One of the top reasons why Cucumber makes the best BDD framework for Selenium is the fact that this tool uses Gherkin language (plain text). So, even a person without any background in programming can understand the application code.

Developers, business analysts, testers, business stakeholders, clients – everyone can understand the application code, which makes process implementation or product release hassle-free.

Focuses on user behavior

The prime goal of any product or process is to deliver a great user experience. Cucumber is a behavior development tool that focuses on the code functionality and how it works with different user behaviors.

As user behavior can be different in real-time situations compared to testing environment, this testing tool can help test all possible user behaviors and evaluate the functional consistency of the codes.

Cucumber Tests All Possible Scenarios

Cucumber can be used to test all possible behavior scenarios of the process. A simple example would be website login. The test can be used to evaluate the results for scenarios such as

  • Different user names and passwords
  • When password is entered wrong – the next steps
  • When user clicks on forgot password
  • When user clicks on forgot user name
  • When user enters the wrong password more than the set number of times

However, while testing, it is possible to limit the number of scenarios tested by using relevant tags. It helps testers focus on feasible scenarios and not test all scenarios.

Data Driven Framework

Selenium has a data driven framework that enables huge codes to be broken down into smaller chunks that correspond to different functions. It also separates the test case from the function. So, Cucumber can be used to test individual functions of codes and evaluate user behaviour and experience. By doing so, testers can identify the exact code regions that affect the end behaviour and fixes can be easily made. It also enables codes to be reused in different scenarios based on the product or process requirements.

Test as the Code is being Built

Initially, developers would build the entire code and then it would be tested for bugs and inconsistencies. However, with Selenium and Cucumber, it is now possible to test even as the codes are being built by the developers. It helps reduce the time required to build a complex code. Also, evaluating program responses to user behaviour as the product is built can help identify gaps and errors in the early stages.

Conclusion

Developers prefer to use Selenium framework for building codes as it supports multiple languages, allows for code reuse, facilitates functional testing of codes and enables web-app testing. Cucumber is a user-friendly Behaviour Driven Development tool that can be easily understood and read by technical and non-technical persons. It also enables testing of user behaviour in different scenarios, which makes the product more effective and scalable. Above all, the easy deployment of Cucumber makes it the preferred BDD framework for integration with Selenium.
