  1. ALMA/ACS Software Engineering M. Zamparelli European Southern Observatory ACS Course Japan, July 2005

  2. Software Engineering • Software Engineering and Quality Assurance activities: • Software Process • Document Reviews, Format, Templates • Development Environment • Integration Procedure • Coding Standards • Code Inspection • Configuration Management • Testing framework and assessment • Change Management ALMA/ACS Software Engineering

  3. Major SE deliverables to ALMA • the tool to build the software with (Makefile) - in maintenance • the version controlled storage area where the software is (CVS) – in maintenance • the problem tracking system (Action Remedy) we use to track faults and change requests - pending replacement/upgrade • the system you document your software with (both inline and online – doxygen, TWiki) – in maintenance • The automated Night Reporting Infrastructure (NRI) which checks standards compliance– in maintenance • generic CASE tools (UML Modeling, Editors, Quality Control) – being updated, reviewed • standards for mostly all the process phases and deliverables ALMA/ACS Software Engineering

  4. <module>/ws/src <module>/ws/object <module>/ws/include <module>/ws/lib <module>/ws/test <module>/ws/man <module>/lcu/src <module>/lcu/include <module>/lcu/man ……. Separation of WS from LCU code Separation of source from headers (for C,C++) Separation of application code from test code ownership assignment, homogeneity Directory Structure ALMA/ACS Software Engineering

  5. esoMakefile • a project wide set of rules, centrally stored and managed. • every developer has to add only the module specific part: the name of the files to be treated! • allows exceptions (it is a normal Makefile) Based on the features of GNUmake and strictly correlated with the environment variable set up and the directory and Software Module standards. ALMA/ACS Software Engineering

  6. <modName>/src/Makefile For every software modules: • defines what has to be build as a list of variables • includes the project-wide rules ($ACSROOT/include/acsMakefile) • defines the standard targets: all, man, install, clean (if necessary, they can be customized) ALMA/ACS Software Engineering

  10. Quality Assurance Tools ALMA/ACS Software Engineering

  11. Automated Inspections (NRI) • Build reports (GO/NO-GO) • Tests (availability, execution results GO/NO-GO, coverage, memory behaviour) • Coding Standards (ALMA, MISRA, Motorola, Scott Meyers, Sun) • Inline documentation sufficiency • lines of code (total, per language, per module, production vs test code) • Algorithmic Complexity (McCabe) • module dependency diagrams • SPR statistics, number of commits, number of unused files • Java duplicate classes verification • Events and Channels in use • metrics on design quality (Robert C. Martin, for Java) ALMA/ACS Software Engineering
