DiUS are keen on this "Agile" thing. We want to develop a tracking system for Agile cards.
Your application should cater for the following:
- Be able to create cards. Cards have a title, description and estimate in points
- Cards belong to an iteration
- Assume a board has only one iteration at the moment
- An iteration can have multiple columns. (It should have at least two, one starting and one done)
- There is a column designated as the starting column. And one designated as the done column.
- Columns have a name
- You can undo your last card column transition. So if you moved it to the done column, you can undo that move by calling a method
- You can calculate the velocity of a given iteration. This is defined as the sum of the points of all cards that are in the done column for an iteration.
- You can get all the cards in a particular column
- You can enforce a work in progress limit (expressed in points) for a column. If you try and add a card to a column that goes above the WIP limit, an exception should be thrown
Your interface should look something like the folllowing:
board = new Board(columns);
iteration.add(card);
iteration.velocity();
iteration.moveCard(card, toColumn);
iteration.undoLastMove();Notes on implementation:
- use Java, Javascript, Groovy, Scala, Ruby or Swift
- try not to spend more than 2 hours maximum. (We don't want you to lose a weekend over this!)
- don't build guis etc, we're more interested in your approach to solving the given task, not how shiny it looks.
- don't use any frameworks (rails, spring etc), or any external jars/gems (unless it's for testing..)
When you've finished, zip up the solution and send it to bmorrison@dius.com.au. Happy coding :)
