Why BDD Automated Testing Fails (and How to Fix It)

Behaviour-Driven Development (BDD) automated testing is an increasingly popular approach that seeks to bridge the gap between development and business teams. By focusing on collaboration and creating test cases that reflect real-world user behaviours, BDD strives to ensure robust software quality and stakeholder alignment.

However, despite its potential, BDD automated testing often fails due to implementation challenges. For automation testers, QA engineers, and BDD consultants, these failures can significantly impact team efficiency, project outcomes, and overall quality assurance practices.

This blog dives into the five key reasons why BDD automated testing fails and provides actionable solutions to help teams optimise their processes.

Understanding BDD Automated Testing

BDD automated testing is a software development methodology and testing approach that places emphasis on collaboration across different stakeholders, such as business analysts, developers, and testers. It leverages a business-readable syntax (commonly Gherkin) to describe application behaviours and ensure that automation test cases align with business requirements.

Key Objectives of BDD

• Foster collaboration between technical and non-technical stakeholders.
• Ensure a shared understanding of application behaviour through readable scenarios.
• Deliver high-quality software by embedding meaningful tests into the development process.

Unlike traditional testing approaches, which may rely heavily on technical test scripts, BDD prioritises scenarios written in plain language. This ensures that both business and technical teams can easily understand and contribute to the testing process.

However, despite these advantages, implementation challenges often arise.

1. Lack of Strong Collaboration Between Teams

Why It Happens

Collaboration is the foundation of BDD, but many teams struggle to establish effective communication between business analysts, developers, and testers. Misalignments in understanding requirements often lead to poorly written scenarios, making it difficult to extract value from BDD.

The Fix

• Regular Cross-Functional Discussions: Organise weekly or bi-weekly meetings where all stakeholders review project requirements and evaluate scenarios together.
• Adopt Collaborative Tools: Use tools like Jira or Confluence to document, track, and share scenarios to ensure everyone is on the same page.
• Implement the "Three Amigos" Approach: Conduct "Three Amigos" meetings (involving a business analyst, developer, and tester) to define scenarios and clarify acceptance criteria collaboratively.

Encouraging a culture of communication and collaboration ensures that teams remain aligned throughout the entire development lifecycle.

2. Poorly Written Scenarios

Why It Happens

When Gherkin scenarios are unclear, overly technical, or ambiguous, they fail to serve their intended purpose.

For instance, scenarios that describe how a feature works, instead of focusing on what behaviour to test, can complicate automation and reduce scalability.

The Fix

• Educate Teams on Gherkin Best Practices:

1. Use simple, concise language.
2. Avoid implementation details in Given-When-Then statements.
3. Focus on outcomes or end-user behaviours.

• Scenario Checklist:

1. Define what to test, not how to test.
2. Ensure scenarios are actionable and testable.
3. Maintain clarity and avoid jargon.

For example, instead of writing

```

Given the user visits the login page

When they enter their credentials and click "Submit"

Then the system checks the database to validate the credentials

```

Write:

```

Given the user visits the login page

When they enter valid credentials

Then they gain access to their account

```

Clarity in scenarios helps both automation testers and business stakeholders focus on the true requirements.

3. Tight Deadlines and Lack of Planning

Why It Happens

Many teams rush into the implementation stage without accounting for the time and effort required to integrate BDD methodologies effectively. Without proper planning, BDD often becomes an afterthought, with poorly defined scenarios and inadequate automation coverage.

The Fix

• Integrate BDD into Project Roadmaps: Include scenario drafting, code reviews, and test automation phases in your project plan to allocate sufficient time.

• Split the Workload:

1. Start with high-priority, high-value scenarios for immediate implementation.
2. Iterate and expand test coverage over multiple sprints.

• Leverage Automation Tools:

1. Use tools like Cucumber, SpecFlow, or Behave to accelerate scenario implementation and streamline the testing process.

By aligning BDD with your development timeline, you create a foundation for successful testing

4. Misuse of Automation Frameworks

Why It Happens

The effectiveness of BDD depends heavily on selecting the right tools and frameworks. Many teams either choose frameworks that don’t suit their tech stack or fail to optimise their chosen framework, impacting efficiency and results.

The Fix

• Choose a Suitable Framework

1. For .NET projects, use SpecFlow.
2. For Python, explore Behave or Lettuce.
3. For JavaScript, consider Cucumber.js.

• Optimise Test Automation

1. Avoid redundant step definitions—reuse whenever possible.
2. Maintain a clean and modular test design to enhance scalability.

• Framework Evaluation Checklist

• Does it integrate with your existing tools (like CI/CD pipelines)?
• Does it support your tech stack?
• Does it offer active community support for troubleshooting?

A well-suited framework tailored to your team’s needs can make or break your BDD implementation.

5. Lack of Maintenance and Continuous Improvement

Why It Happens

Initially successful BDD implementations can falter if scenarios and step definitions become outdated or neglected. Without maintenance, automation efforts lose relevance and impact.

The Fix

• Adopt Continuous Test Maintenance

1. Schedule regular reviews of step definitions and scenarios to ensure they remain valuable.
2. Designate a team or individual to oversee test maintenance.

• Integrate Testing into CI/CD Pipelines

Use tools like Jenkins, CircleCI, or Azure DevOps to automate test execution and incorporate maintenance into routine workflows.

• Encourage Feedback Loops

Establish a culture of continuous improvement where team members provide input to refine scenarios and processes.

Proactively maintaining your test suite ensures long-term success and adaptability.

Take Your BDD Automated Testing to the Next Level

BDD automated testing has the potential to drive collaboration, improve software quality, and align testing with business goals. However, common pitfalls—such as poor collaboration, poorly written scenarios, tight deadlines, improper framework use, and neglect- can hinder its success.

By proactively addressing these challenges, teams can unlock the full power of BDD and create a scalable, efficient testing process that delivers meaningful results.
