Fast Shell Utilities to Report Maven's Unit Tests Results

I would like to share a couple of shell utilities that I have collected. These are for fast Maven multi modules reporting from your unit tests results, without having you to run entire Maven site reports, which can take a LONG time to generate if you have a large project! They should work on Linux or Window's Cygwin shell.

# Show failed tests among all the surefire results.
function failedtests() {
    for DIR in $(find . -maxdepth 3 -type d -name "surefire-reports") ; do
        ruby -ne 'puts "#$FILENAME : #$&" if $_ =~ /(Failures: [1-9][0-9]*.*|Errors: [1-9][0-9]*.*)/' $DIR/*.txt
    done
}
# Show the top tests that took the longest time to run from maven surefire reports
function slowtests() {
    FILES=''
    for DIR in $(find . -maxdepth 3 -type d -name "surefire-reports") ; do
        FILES="$FILES $DIR/*.txt"
    done
    head -q -n 4 $FILES \
        | ruby -ne 'gets; print $_.chomp + " "; gets; print gets' \
        | ruby -ane 'printf "%8.03f sec: ", $F[-2].to_f; puts $_' \
        | sort -r \
        | head -10
}

When developing with Maven, you often want to see a summary of failed tests, and you want those surefire TXT file content to see what's going on. The failedtests function will give you a list of all the failed tests filenames in all modules; and then you can cat each one to investigate.

With slowtests function you may quickly see the top 10 most time consuming tests from your project!

Enjoy!
