Why Choose Flow BDD?

The most productive way to implement Behaviour Driven Development. You write the code first and this generates documentation and diagrams.

Do more with less

Focus on your tests and best practices. Flow BDD is an open source framework that uses "Wordify" to translate your clean Java code into beautiful, interactive docs.

Code-First, Always

Write clean JUnit 5 tests. No regex glue, no brittle feature files, no framework overhead, just one annotation!

Visual Debugging

Get automated Mermaid.js sequence diagrams for every test run to see exactly where communication breaks.

Boundary Assurance

Perfect for AI-assisted coding. Ensure LLM-generated logic follows the expected behavioral boundary.

Why do functional testing including BDD

Verifying Behavior

Ensuring the system does exactly what the business intended.

Enabling Refactoring

Providing the safety net needed to improve code without breaking functionality.

Living Documentation

Acting as the ultimate source of truth for how the system actually works.

Increased agility

Iterating with Fast Validated Feedback, Value Amplification, Waste Elimination

The Traditional BDD Problem

Tackle the "Gherkin Tax"

Traditional frameworks like Cucumber, JBehave etc... often lead to code duplication and massive refactoring overhead. Flow BDD removes the following:

Four layers of complexity (Feature, Glue, Orchestration, FT Framework)

Corrupted code caused by rigid feature file structures

High maintenance costs and diminishing returns as projects grow

Brittle Regex mappings that break during refactoring

Be more productive

Be more productive, with higher quality tests and less code

Higher quality tests and less code

Less complexity

Lowering the cost of maintaining and adding testing

Increasing productivity

Oh, and you get sequence diagrams plus many new features are in the pipeline
