Scenario Testing: Using Behavior-Driven Development (BDD)

Behavior-Driven Development, or BDD, is one of the sophisticated software development approaches. It mainly improves partnerships between software development, testers, & stakeholders. Behavior-driven development highlights scripting scenarios in a standard language format that can be effortlessly understood by the team.

This practice, called scenario testing, plays a crucial role in the Quality Assurance (QA) process by defining short, clear, and testable behaviors for the software.

In scenario testing, Behavior-Driven Development (BDD) leverages the Gherkin language to define key traits and their expected results in a structured manner. This guarantees that QA teams have a complete understanding of the needs and can effectually validate that the software meets its proposed functionality.

By incorporating Behavior-driven development (BDD) into the QA workflow, teams can enhance communication, spot issues early, and accomplish better test coverage, eventually resulting in top-quality software.

What is BDD testing?

BDD or Behavior Driven Development, is a software development method for writing test cases in normal English. It assists QAs with zero technical know-how to comprehend what is going on in the project, which closes the gap between technical and business persons. The Behavior-driven development approach is simpler to understand and has lower technicality.

The crucial advantage of behavior-driven development (BDD) is that it is derived from TDD (test-driven development), which supports Automation testing with multiple test data and minimal code interference.

Behavior-driven Development is employed through the Cucumber framework for automating test cases in a clear and perfectly organized manner. Cucumber feature files are scripted in a language termed Gherkin that ends with .feature extension.

How do you write a BDD scenario?

A BDD (Behavior Driven Development) scenario is written through the Gherkin language and usually follows a “Given-When-Then” approach.

  • Given: The primary state or context of the system.
  • When: The event or action that activates the scenario.
  • Then: The projected result or outcome.

The syntax makes it simple for all stakeholders to know and check the system’s behavior.

Limitations of BDD (Behavior-driven development)

Even though Behavior-driven development has several challenges, benefits also exist. To completely realize the profits of customer-centric development and guarantee successful deployment, it is imperative to understand & tackle these challenges.

Stages of BDD (Behavior-driven development)

Behavior-driven development comprises 3 crucial stages:

  1. Detection
  2. Preparation
  3. Automation

How does Behavior-driven development profit the QA procedure?

BDD (Behavior-driven development) proffers multiple rewards to the quality assurance procedure, improving the overall consistency and quality of software. Let’s check out how Behavior-driven development advantages the Quality Assurance procedure:

  1. Enhanced Collaboration & Better Communication
  • Normal Language: Behavior-driven development utilizes standard and easy language for writing scenarios, which bridges the gap between experts and non-technical in a team. This confirms that everybody, including QA’s, developers, plus stakeholders, understands the projected behaviors and necessities of the software.
  • Shared Understanding: By including all stakeholders in the conception of scenarios, Behavior-driven development (BDD) promotes mutual know-how of the project requirements and acceptance conditions.
  1. Concise and Clear Requirements
  • Specific Specifications: Scenarios written in Gherkin language offer specific and clear specifications of how the software must behave. This lessens ambiguity and assists QA teams know exactly what needs to be tested.
  • Constancy: The structured format of Behavior-driven development (BDD) circumstances (Given-When-Then) confirms constancy in how necessities are documented & tested.
  1. Early Discovery of Issues
  • Requirement Justification: By defining test scenarios early in the software development procedure, potential problems and misunderstandings can be recognized and fixed before coding starts. This decreases the likelihood of flaws later in the development cycle.
  • Continuous Feedback: Behavior-driven development (BDD) supports CI (continuous integration) and continuous testing, enabling Quality Assurance teams to obtain immediate feedback on the influence of changes and catch problems early.
  1. Improved Test Coverage
  • Comprehensive Test Scenarios: Behavior-driven development encourages writing comprehensive scenarios that cover multiple use cases, user interactions, and edge cases. This guarantees comprehensive testing and decreases the chances of missing crucial test cases.
  • Behavior Focus: Focusing on the software behavior rather than its execution details results in meaningful and user-centric testing.
  1. Effectiveness and Automation
  • Test Automation: Behavior-driven development scenarios can be directly converted into test automation using tools such as Behave, Cucumber, and SpecFlow. This lessens the necessity for manual tests and enhances the effectiveness of the Quality Assurance process.
  • Reusable Steps: The step definitions in Behavior-driven development (BDD) are reusable, which saves extra effort and time while generating new tests for the same functionalities.
  1. Living Documentation
  • Updated Documentation: Behavior-driven development (BDD) scenarios serve as living documentation that changes with the software. They offer an accurate and current description of the system’s behavior, which is valuable for future development and maintenance.
  • Traceability: Linking scenarios to user requirements or stories gives traceability, confirming that all necessities have corresponding test cases.
  1. User-Centric Tests
  • Focus on User Experience: Behavior-driven development scenarios are written from the user’s perspective, confirming that the software meets user prospects and delivers a positive user experience.
  • Real-Time Scenarios: Testing real-time circumstances helps QA teams validate the software’s features in user-centric, practical contexts.
  1. 8. Lesser Regression Issues
  • Regression Automation Tests: With Behavior-Driven Development, test automation can be conducted frequently to ensure that fresh alterations do not damage current functionality. This helps manage the constancy of the software over time.
  • Constant Tests: Incorporating Behavior-Driven Development with Continuous Integration/ Continuous Delivery pipelines enables frequent testing, giving constant validation of the software as it progresses.

What are Scenario tests in Behavior-Driven Development?

It is a modern technique of defining and validating the software’s behavior through particular, illustrative instances written in a standard format. Such scenarios define how the software should act in specific situations, guaranteeing that all stakeholders have a common knowledge of the needs and projected results.

Key Aspects of Scenario Testing in BDD:

  • Plain Language Descriptions: Scenarios are written in simple language using the Gherkin syntax, keeping them accessible to everybody involved in the project, counting QA teams, software developers, and non-technical stakeholders.
    • Structured Format: Scenarios usually follow a “Given-When-Then” format:
    • Given: The primary context or condition of the system.
    • When: The event or action that triggers the scenario.
    • Then: The projected output or result.
  • Collaboration: Scenario testing accelerates collaboration among teams by including all stakeholders in the formation of the scenarios. This confirms that the necessities are clearly agreed upon by every person.
  • Automation: Scenarios (mentioned in Gherkin) can be automated using Behavior-Driven Development tools such as SpecFlow, Cucumber, and Behave. Such tools execute the scenarios as automation testing, guaranteeing that the software behaves as anticipated.
  • Documentation: Behavior-driven development scenarios serve as active documentation that progresses with the software. They give a clear and updated description of the software’s behavior, which is precious for management and future development.
