auction-system's Introduction

auction-system

A simple auction system implementation, provides a bid tracker interface and concrete implementation with the following functionality:

Record a user's bid on an item
Get the current winning bid for an item
Get all the bids for an item
Get all the items on which a user has bid

The project includes an API, implementation, unit tests and a barebones web frontend.

Run the web frontend (e.g. in linux) with the following commands:

mvn clean install
java -jar webapp/target/webapp-1.0.0-SNAPSHOT.jar

then browse to http://localhost:8080

auction-system's Issues

Set up license header enforcing

Set up maven so that the build fails if any java source file is missing the appropriate license header

Improve web frontend layout and styling

Javadoc coverage

Current javadoc coverage of the project is empty.

Handle bidding corner cases

Currently, several corner cases when bidding on items are not handled or behave in a nondeterministic way, for example:

When two users bid with the same amount, it's unclear who will be returned by getWinningBid()
An user can potentially issue a bid with a lower price than his previous bid

Externalize properties from persistence.xml

Some properties used for testing (e.g. hibernate schema generation) were typed directly into the persistence.xml file. They should be externalized in a properties file so that production values can be set differently from test context values

Refactor API dataobjects to avoid redundancy

Right now there are several different objects with the same purpose (holding bid data), they should probably be refactored to reduce their number

Improve unit test coverage

right now, the integration test only cover successful use cases. It should also cover missing parameter handling, etc.

Web frontend should provide feedback when submitting new bids

Web frontend: perform data validation and provide meaningful feedback

Repackage the webapp project as a WAR file
