Iteration 2 - Vehicle Class Implementation

Overview

In this iteration, I implemented the Vehicle class, which represents a vehicle with passengers and tracks whether it is speeding. The class includes methods to add passengers, check speeding status, and count adult passengers.

Key Features Implemented

• Vehicle Class:

  • Initialized with year, make, and model attributes.
  • Tracks whether the vehicle is speeding.
  • Manages passengers inside the vehicle.

• Key Methods:

  • initialize: Initializes the vehicle with year, make, and model, and defaults for speeding and passengers.
  • speeding?: Returns whether the vehicle is speeding.
  • speed: Sets the vehicle to speeding.
  • add_passenger: Adds a passenger to the vehicle.
  • num_adults: Returns the number of adult passengers in the vehicle.

Test Coverage

• I used TDD to ensure the Vehicle class behaves as expected:
  • Initialization of vehicles with the correct attributes.
  • Correctly tracking speeding status.
  • Adding passengers and correctly counting the number of adults.

Challenges

• Handling missing attributes during initialization (e.g., nil values for year).
• Ensuring accurate counting of adult passengers in the vehicle.

Fixes

• Addressed failing tests related to missing attributes by adding default values.
• Ensured that the speeding? method reflects the vehicle’s true speeding status after calling the speed method.
• Corrected test expectations for the number of adult passengers.

Reflection

• Successfully implemented all features for the Vehicle class using TDD.
• All tests have passed, and the class is ready for further integration with the rest of the system.
