Hi! We've started to generate code coverage reports for test suites of some projects on a regular basis. You'll find on overview for LibreSSL (Portable) here: http://www.opencoverage.net/libressl/index_html/sources.html Out of 59877 conditions and decisions 13389, or 22.36% were covered during yesterdays run. OpenSSL currently has 67832 conditions/decisions, i.e. the project's goal of simplifying the code has been reached. The percentage covered through the test suite is lower however. Hence I wonder whether our use of the Linux port or our build configuration is to blame. You might be able to use the reports for your coding and testing efforts. Attempts to increase test coverage can sometimes result in spotting of buggy code paths. If you spot a problem with our setup or have any questions please drop me a note. Harri.
