  3. QA in Open Source Projects Here: Technical aspects independent of ISO-certification Diverse, not always as desired Tools to support process

  4. QA Tools Bug Tracking (RequestTracker, OTRS) Code Checker (lint etc.) Memory Monitor (Valgrind, Electric Fence) Compiler Warnings (-Wall -Wextra !) Black box testing (dejagnu) Unit testing (JUnit, autotools)

  5. Unit Testing Background: eXtreme Programming Goal: Automated, ubiquitous testing Frameworks: Junit, PyUnit, Test::Unit, autounit, ...

  6. Autotools

  7. autotools Standard GNU framework autoconf, automake, libtool, etc. Used in typical Open Source projects Generated configuration scripts in packages ./configure && make && make install Goal: “make test”

  8. Embedded Aspects Cross toolchains autotools are prepared for cross compilation Problem: Program execution on target TESTS_ENVIRONMENT=ssh username@targethost Prerequisite: Target is powerful enough to execute tests in addition to normal program Transparent evaluation of results

  9. Example Test Protocol
