The service allows users to search for flights between two cities, specifying a date range and preferences. It recommends the best flights based on price and availability, considering factors like layovers and travel duration.

Requirements

Modernized TDD Scenario: TV Price Comparison Service

Scenario

Test-drive code that compares prices on smart TVs from three different sources, each with modern or legacy data access methods. The service will allow users to specify the make and model of a TV and recommend the retailer(s) offering the best price.

Data Sources

An online retailer providing a RESTful web API.

Music Streaming Service

Test-drive code that manages the catalog and subscriptions of a digital music streaming service. Customers can browse and search the catalog by title, artist, and genre. Record labels and independent artists submit their tracks to the platform, and the service maintains a catalog with details about each track, including the streaming rights and availability status.

Key Features
