• Run git clone https://github.com/shezdev/honeycomb-makers-test
• cd honeycomb-makers-test (root directory)
• Run bundle install in the root directory

• Run ruby run_ex1.rb to execute the first example, which should look like this:

• Run ruby run_ex2.rb to execute the second example, which should look like this:

• I used a test-driven approach to build this functionality using RSpec.
• To test:
• Run rspec from the root directory
• Currently shows 19 examples, 0 failures

• Most of the functionality was provided in the example given to us in /example
• I re-wrote the functionality from scratch using a TDD Approach
• I delegated output/printing to a Printer module, that mixed in to the Order class.
• When it came to building the new functionality (a mechanism for applying Discounts to orders), I built another module called "Promotions", that also mixed in to the Order class.

We have a system that delivers advertising materials to broadcasters.

Advertising Material is uniquely identified by a 'Clock' number e.g.

• WNP/SWCL001/010
• ZDW/EOWW005/010

Our sales team have some new promotions they want to offer so we need to introduce a mechanism for applying Discounts to orders.

Promotions like this can and will change over time so we need the solution to be flexible.

These are the Broadcasters we deliver to

• Viacom
• Disney
• Discovery
• ITV
• Channel 4
• Bike Channel
• Horse and Country

• Standard Delivery: $10
• Express Delivery: $20

• Send 2 or more materials via express delivery and the price for express delivery drops to $15
• Spend over $30 to get 10% off

Provide a means of defining and applying various discounts to the cost of delivering material to broadcasters.

We don't need any UI for this, we just need you to show us how it would work through its API.

Based on the both Discounts applied, the following examples should be valid:

• send WNP/SWCL001/010 to Disney, Discovery, Viacom via Standard Delivery and Horse and Country via Express Delivery based on the defined Discounts the total should be $45.00

• send ZDW/EOWW005/010 to Disney, Discovery, Viacom via Express Delivery based on the defined Discounts the total should be $40.50
