Scientific Software DevelopmentDaily Observations in Research Labs and Industry…
Specific phenomenon: developments starting small (short script) but grow larger and larger during time
Team sizes: from 1 student to > 50 scientists from several departments
Lots of scientists (i.e. mathematicians, physicists, engineers) have no education in software engineering but developing large and/or critical applications
Their aim: fast implementation or their ideas into running code
Loss of productivity through archaic tools und procedures
old text editors (vi, Emacs, Notepad)
code exchange via e-mail, memory sticks or NFS
no methodical testing

SVNCheckerHook Script Framework for Subversion
Function
Better integration of version control in the dev process
Especially the connectivity to the bug tracking system
Usage
Called by subversion via a hook (pre-commit, post-commit)
External tools will be integrated via plug ins

configWebService
Configuration interface via WebService:
Changes can be seen fast
Dev team can make changes easily
Small amount of administrative action needed

SVNCheckerFuture activities (no time schedule)
Planned extension:
Graphic UI for configuration
Through a web interface and/or via an eclipse plug-in
Visions:
Fully fledged test suite
Complete traceability of developement process
Integration of provenance recording (http://www.gridprovenance.org)
