Alle unsere Java Klassen verwenden einen einheitlichen Style. Außerdem verwenden wir Checkstyle bzw. das Checkstyle Eclipse Plugin, mit vordefinierten Rules, um keine Zeit bei der Entwicklung zu verschwenden.
Die Checkstyle rules sind im JVx Repository unter dem Dateinamen
<jvx>/trunk/java/library/checkstyle_opensource.xml
abgelegt.
Für Klassen verwenden wir folgenden Style:

Folgende Regeln werden durch diese Vorlage definiert:
String sValue = "bar";
Für Interfaces verwenden wir folgenden Style:

Durch den Einsatz von Unit Tests stellen wir sicher das die Basisfunktionalitäten wie erwartet funktionieren. Ein Unit Test kann niemals die komplette Funktionalität in allen erdenkbaren Konstellationen testen, doch ohne Unit Tests können die Qualitätsanforderungen nicht erfüllt werden. Wir setzen daher ein funktionierendes Set an Unit Tests voraus.
Die Unit Tests werden getrennt vom Core Source Code gespeichert:
<jvx>/trunk/java/library/src/com/sibvisions/foo <jvx>/trunk/java/library/test/com/sibvisions/foo
Als Testing Framework kommt JUnit zum Einsatz.
Für Unit Tests verwenden wir folgenden Style:
