Software Quality: JSF Component Libraries


Working for a larger sofware company has some advantages. One of them is, to have a software quality checker at hand, which can be easily configured to run on any java project. What is called "msgJavaMessplatz" (Java measuring station) depends on quite popular tools.

- JavaNCSS - A Source Measurement Suite for Java
JavaNCSS is a simple command line utility which measures two standard source code metrics for the Java programming language. The metrics are collected globally, for each class and/or for each function.

- Checkstyle 4.4
Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard.

- FindBugs
Is a program which uses static analysis to look for bugs in Java code.

- Simian v 2.2.17
Simian (Similarity Analyser) identifies duplication in Java Code.

- Dependometer
Dependometer performs a static analysis of physical dependencies within a software system.

- Cobertura
Cobertura is a tool that calculates the percentage of code accessed by tests.

This was planned for quite some time now. Today, I finaly managed to setup the testing environment and run a few quality checks with the first candidates.
To give you a brief overview of the candidates, here are the basic metrics in terms of size and quality. I will compile more detailed results during the week and publish selected results. So stay tuned for more ....
