Overview

Behavior-Driven Development (BDD) is a collaborative software development practice that bridges the gap between business stakeholders, developers, and testers. It combines principles from Test-Driven Development (TDD) and Domain-Driven Design (DDD) to focus on the expected behavior of applications from a user's perspective.

Why is BDD in the GitOps-Lab?

This repository focuses on creating robust Kubernetes-based infrastructure that supports modern application development practices. BDD is included as a critical part of the testing strategy to ensure that application deployments align with business requirements and behave as expected under various scenarios.

  • Integration with CI/CD Pipelines:

    • BDD tests will act as guards for application deployments.
    • These tests will be integrated into the CI/CD pipelines, ensuring that staging environments are validated before promoting changes to production.

  • Cluster-Based Testing:

    • BDD tests will run directly against applications deployed on Kubernetes clusters.
    • This approach ensures that tests validate real-world behavior, taking into account the actual runtime environment.

Planned Setup

Infrastructure for BDD Testing

  1. Staging Environments:

    • BDD tests will target staging environments deployed within the Kubernetes cluster.
    • Each deployment pipeline will provision isolated staging environments for running tests.

  2. Testing Frameworks:

    • Cucumber:
      • Used for both .NET Web API and React frontend applications.
      • Supports writing test scenarios in Gherkin, ensuring clarity and collaboration between stakeholders.
    • Cluster Access:
      • CI/CD pipelines will grant BDD tests access to the staging environments via kubectl or API gateways.

  3. CI/CD Integration:

    • Pipelines will execute BDD tests as part of the pre-deployment checks for staging environments.
    • Only deployments that pass all BDD tests will be considered for promotion to production.

Key Features of BDD

  • User Stories and Scenarios:
    • User stories describe the desired behavior of the application in simple terms.
    • Scenarios provide concrete examples of behavior, written in plain English using the Gherkin language.
  • Automated Testing:
    • Scenarios are converted into automated tests that validate the application's behavior against the defined requirements.
  • Continuous Validation:
    • Ensures that applications consistently meet business requirements as they evolve.

Example BDD Scenario

Scenario: User logs in successfully
  Given the user is on the login page
  When the user enters valid credentials
  Then the user is redirected to the dashboard

Benefits of Integrating BDD in GitOps-Lab

  • Alignment with Business Requirements:
    • Ensures that applications deployed on Kubernetes clusters meet user expectations.
  • Improved Collaboration:
    • Encourages communication between developers, testers, and business stakeholders through shared understanding of application behavior.
  • Deployment Confidence:
    • Acts as a safety net, allowing only validated deployments to proceed to production.
