A Legacy Code kata that focuses on refactoring an ugly piece of legacy code.

This kata contains a lot of common flaws for pedagogical purposes:

• Cyclomatic complexity
• Code duplication
• Lack of dependency injection
• Dependency cycle
• Bad Entity/Value-object choice
• Non-deterministic processing
• Static service

This is an application to search facts ("birth of Elvis Presley"...) by keywords, and to find related facts as well.

You're given this code base with the following instructions:

• BUG: when the user enters a too long sentence in the input, then the application closes
• ENHANCEMENT: we need to evolve the dates comparison: facts with the same days (and month) on different years must be considered equals

• Start to test manager.get() : check that get("Mort elvis") return "Mort d'Elvis Presley"
• You can split Dao into production and Stub implementation with interface
• Add constructors to inject DaoStub

• you can install jar with the following command:

mvn install:install-file -Dfile=libs/company-api-1.0.jar -DgroupId=fr.arolla.jam -DartifactId=legacy-kata-dependency -Dpackaging=jar -Dversion=1.0
