Behavior-Driven Development (BDD) Widget Testing in Flutter

Testing plays a crucial role in ensuring the reliability of Flutter applications, and Behavior-Driven Development (BDD) helps developers create readable, structured, and maintainable test cases.

In this blog, we’ll explore bdd_widget_test, a BDD-style widget testing framework that automatically generates Flutter widget tests from Gherkin .feature files.

By the end, you’ll be able to write, generate, and execute BDD tests in Flutter with ease! 🚀

📌 Why Use BDD in Flutter?

✅ Readable Tests → Written in Given-When-Then format, making them easy to understand.

✅ Better Collaboration → Non-technical stakeholders can review and contribute.

✅ Automated UI Testing → Ensures app behavior matches expectations.

📌 Setting Up BDD in Flutter

1️⃣ Add Dependencies

Update your pubspec.yaml:

dev_dependencies:
  build_runner:
  bdd_widget_test: <latest version>

flutter pub get

📌 Writing BDD Test Cases in Flutter

2️⃣ Create a Feature File

BDD tests are written in .feature files using Gherkin syntax.
