Treasure map

Prerequisites

• JDK 14

Build project

./gradlew build

Run tests

./gradlew test

Framework usage

I used Spring Boot 2.2 framework for this app.
I did not used it in domain packages to be framework agnostic (only Java core allowed) I mainly used it for :

• testing
• DI (it could be done manually but SB do it well for me)

What could be improved?

• Treasure quest with multiple users has not been implemented
• Add additional checks on treasure map configuration (a same box should have only one type)
• Use a domain id (which is an UUID) for explorer (instead of name)
• Add log message on exceptions

Performances

I did not do benchmarks on large CSV files but in ApplicationFactory the method toDomain use 5 times filter stream method. This method is in O(n) so performance could be not really good on large collections.
One solution could be using builder for treasure map construction

Output

Csv result file is dropped in output/ folder

Git history

I did not autosquash my work deliberately in master branch to show the way I work so there is lots of fixme commits
