Nose is a tool to detect the evolution of bad smells over several versions of a Java SVN repository. It is just a Clojure program that automates the task by running inFusion over the specified versions of the project and stores the results in a serverless database for its study. The motivation and the results obtained can be found in the report.
If you want a quick overview, you can have a look at the presentation given by Javier Pérez at the Belgium and Netherlands software evolution workshop.
The application can be used with leiningen by checking out this repository or the latest version of a standalone jar can be downloaded from the tags section of this repository.
It can be launched by using java -jar.
The application has three subcommands:
-
db, which manages the database. At this moment it only accepts another subcommand,create, which creates a database calledsmell_history.sqlitein the work directory. -
analyse, which runs inFusion for a project and takes three arguments. The first one is the location of the inFusionC executable, which bundles with inFusion. In the OS X application it can be found inside it, ininFusion.app/Contents/MacOS/inFusionC. The second one is the location of a svn repository containing the project to be analysed. The third one is an existing folder where the xml reports will be created.There are two options available:
-for--first-revisionthat specifies the starting revision. The default value is 0.-lor--last-revisionthat specifies the last revision. The default value is the max revision of the repository.-sor--stepthat specifies how continuos the revisions are. Will iterate over the repository using such increments. The default value is1.
-
transform, which takes a folder that contains the inFusion reports and loads them into the database.
The results obtained in the database can be processed in order to obtain further information. The paper presents the study of bad smells removals in four software repositories.
