A Walk through of Behavior Driven Development (BDD) for Every Business

This article is a walkthrough of Behavior Driven Development (BDD) for every business. BDD makes it easier to automate tests so that you can achieve maximum efficiency with your Application development. With BDD, you can establish a process for automated testing that allows you to quickly and easily test changes in code and verify behavior. Automated tests can be triggered when code is changed, reducing the effort involved in testing each change. This enables teams to test changes faster and with greater assurance of quality, leading to higher customer satisfaction in your product.

What is Behavior Driven Development?

A user’s expected behavior when engaging with an application, is documented and designed into the program using the agile software development process known as behavior-driven development (BDD). Bloat, bloated code, unneeded features, and lack of concentration may all be avoided by developers by pushing them to concentrate just on the desired behaviors of a program or app. The techniques used in acceptance testing and test-driven development (TDD) are combined, improved, and combined in this methodology. A typical behavior-driven development project would start with a discussion between the managers, customers, and developers to get a general idea of how the product is intended to function. When all of the behavior tests are passed, the product has complied with all criteria and is prepared for delivery to the customer. The behavior expectations for the product are then set as goals for the developers.

Features of Behaviour Driven Development:

1. Switching from testing to behavior-based thinking
2. Ensures that the business stakeholders, business analysts, the QA team, and developers are working together.
3. The language that is commonplace is simple to define.

BDD frameworks like Cucumber or JBehave are enablers, acting as a “bridge” between Business & Technical Language. It is driven by Business Value and Extends Test-Driven Development (TDD) that uses natural language that even non-technical stakeholders can also understand.

BDD Tools Cucumber:

A wonderful testing framework that supports behavior-driven development is called Cucumber (BDD). It allows the users to express application behavior using a straightforward grammar specified by a language called Gherkin in plain meaningful English text. Although Cucumber is built in Ruby, it may also be used to “test” programs written in Java, C#, and Python in addition to Ruby.

How SpecFlow works:

The Ruby on Rails Cucumber framework served as a model for SpecFlow. Cucumber expresses user stories using the Gherkin format in plain English. The Cucumber gem is used to run the user stories after the expectations for each story that have been written. A similar idea is used in the NET environment by SpecFlow, which enables the developer to express the feature in straightforward English. It also enables the writing of specifications in Gherkin format for better human reading.

Feature File:

• The feature file is a crucial component of the cucumber tool which is used to create acceptance phases for automation testing. The application definition is often followed by the acceptance steps.
• Typically, a feature file is a shared file that contains the features, situations, and feature descriptions that will be tested.
• The feature file serves as both a starting point for writing the cucumber tests and a live document during testing.
• The feature file has the “feature” extension.
• There must be a distinct feature file for each program feature.

Step Definition

• A procedure containing an expression connecting it to one or more Gherkin steps is known as a step definition.
• The cucumber will search for a step definition that matches the Gherkin step when it executes a Gherkin step in a scenario.
• Step definitions are not connected to a specific scenario or feature file.
• A step definition’s file, class, or package name has no bearing on the Gherkin steps it will match.
• The expression of the step definition is all that matters.

Test Runner:

• As the name itself suggests, Test Runner class require to run the features file and generate report
• It is a library that picks the test files and the source code directory to run in order to check for faults and problems.
• The Test Runner additionally makes sure that the file is executed and notifies if the test files are operating as intended to fulfill benchmark standards.
• The Test runner can execute functional tests and output results in line with the configuration.
• The Test Runner should be able to run test files on a variety of actual devices in order to run tests and find faults in the test suite quickly and accurately.

Reports in BDD Framework:

There are many open-source tools available that can generate awesome pretty HTML reports (Extent Reports, Masterthought). The term “HTML Report” refers to reports created online or through HTML report generators utilizing the HTML language.  This report comprises with details of feature files, feature steps, no of steps passed, no of failed steps, and details of failed steps along with error console log and snapshot. This report is mapped with Behavior of Application and meaning full for business reporting.

In the above walkthrough, we found that Behavior Driven Development (BDD) is an awesome framework for every business. It changes the way of Automation and the way we report the automation reports to businesses. At ThoughtCoders, we have specialized Automation professional teams who can develop automation frameworks within a short span of time. Some cool features of Behavior Driven Development frameworks are:
