Debugging a failing test doesn't include the full stack

by Esteban A. Maringolo

I'm trying to debug a failing test case in Pharo 5, but for some reason in certain tests I can't see the full stack, so basically I can't fix nor diagnose the failing test within the debugger because I only get the assert notification. This doesn't happen in Pharo 4, there seems to be a refactoring of the TestCase hierarchy, but I don't know how it affects the exception handling, which in the case of Glorp seems to not be very orthodox. Regards! â Esteban A. Maringolo

problem using curl and wget in zero-conf

by Dale Henrichs

I've been using zero-conf scripts to download the pharo vm for a while and occasionally the download fails to install the vm in the pharo-vm directory .... silently ..... with no clue as to what happened. even worse the exit status is zero so the failure isn't noticed until much later on in my install when an attempt is made to actually use the vm .... I do know that when I see these failures the pharo-vm does get created but is empty ... I got another failure today and figured that I would dig into this on my end to see if I could understand what might be going on .... The section of the zero-conf script that is suspect is the following: mkdir $VM_DIR $DOWNLOAD_TO$VM_DIR/vm.zip $VM_URL After the $VM_DIR is created (which I know happens), the $DOWNLOAD_TO script is run. Recently, I learned that a side effect of using the --silent option for curl is that error messages are also suppressed and I see that for curl, the `--silent` option is being used: if [[ `which curl 2> /dev/null` ]]; then DOWNLOAD="curl --silent --location --compressed "; DOWNLOAD_TO="$DOWNLOAD --output "; elif [[ `which wget 2> /dev/null` ]]; then DOWNLOAD_TO="wget --quiet --output-document="; DOWNLOAD="$DOWNLOAD_TO-"; else echo "Please install curl or wget on your machine"; exit 1 fi For curl if you want to turn off the progress meter (a good thing) and continue to report errors, you need to use --show-error in conjunction with --silent (as described in the man page) I think the same thing applies to wget, --quiet turns off error messages and progress .... you probably should be using --no-verbose to continue to get error messages ...

Re: [Pharo-dev] test coverage for String

by sheridan＠sheridan-mahoney.com

Hi Alexandre, Thanks for the reply - I was able to get things working. With regard to test coverage for String, I just wanted to let you know I'm adding tests in this area (just to hopefully prevent duplicate efforts...). Cheers, Sheridan ------------------------------ [ For people not aware of Hapao: Hapao is a visual test coverage tool for Pharo. More info on: http://bergel.eu/download/papers/Berg12c-HapaoSCP.pdf [37] ] Hi Sheridan, How did you load Hapao? Roassal seems to be missing. The following should work: Gofer it smalltalkhubUser: 'ObjectProfile' project: 'Spy2'; configurationOf: 'Spy2'; loadStable. I can get the coverage of the class String. Here is the result by the way: https://dl.dropboxusercontent.com/u/31543901/TMP/StringCoverage/index.html [38] Interesting to see that, despite all the unit test that uses String, String is not even 50% covered. I have attached the html coverage report to this email. Cheers, Alexandre
