At Trade Me we're looking to make selling items even easier and so we've decided to build our very own package shipping network. We've dug a tunnel between the North and South Islands that enables us to offer the same rates for parcels sent anywhere in the country, and we've just finished fueling up our fleet of courier vans; all that remains to be done is to update the website so that users can be advised how much their items will cost to send.
Our new service shipping costs are based on size and we offer different prices for small, medium, and large boxes. Unfortunately we're currently unable to move heavy packages so we've placed an upper limit of 25kg per package.
| Package Type | Length | Breadth | Height | Cost | | --- | --- | --- | --- | --- | --- | | Small | 200mm | 300mm | 150mm | $5.00 | | Medium | 300mm | 400mm | 200mm| $7.50 | | Large | 400mm | 600mm | 250mm | $8.50 |
We need you to implement a component that, when supplied the dimensions (length x breadth x height) and weight of a package, can advise on the cost and type of package required. If the package exceeds these dimensions - or is over 25kg - then the service should not return a packaging solution.
You will be expected to produce a solution that solves the above problem. While this is a simple component we would expect it demonstrate anything you’d normally require for a production ready and supportable solution - so think about standards, legibility, robustness, reuse etc. What we don’t require is a fancy user interface - a simple command line or test harness will suffice.
You are free to choose how you implement the solution though your choices should ideally align with your skills and the role you are applying for. You are welcome to make assumptions about the solution along with any improvements you think enhance or add value to the solution - though please be aware of the original scope.
We will send you an invite to our Bitbucket git repository where you can commit or upload your code. Once finished let us know via email and we’ll take a look.
Best of luck, and we look forwards to your response!
a. The task is implemented with .NetCore3.0 in Vistual Studio.
b. 5 Projects are added to the solution. They are Console Project for demo, Business class library, Data Model class library, Unit Test Project, Utility class library.
c. Unit Testing is implemented with xUnit, Moq libraries.
d. Project implementation tries to refer to the SOLID principle and makes each component more independent and reusable.
e. Factory Pattern is used to implement retriving existing package type information from multi data sources.
Thanks again for sharing this opportunity and I appreciate your time reviewing my code.
Any questions, suggestions and comments are more than welcome.
