I just pushed a change for my teammates: we’re now using Bundler on our Rails 2.3.5 application. Things went rather well, but our continuous testing server choked a bit on that.

First, I had forgotten to run bundle install after pulling changes. Then I had to ignore our cucumber environment, because it depends on rb-appscript which is a native gem on Mac OS X. Our CT machine is a Linux box, hence the change. Then, bundle install would fail installation because it didn’t have sudo access:

I was busy writing a message to the Ruby Bundler Google Group when I remembered bundle install has an optional parameter which specifies where the bundle should be installed. I changed my CT script to run bundle install --without=cucumber vendor/gems and bundle did it’s magic, and my CT box started running tests.

Much rejoicing ensued.

For the record, here’s our testing script:

 1 #!/bin/bash
 2 cd /home/francois/adgear-admin
 3 
 4 if [ -z $1 ] ; then
 5         echo "Can't proceed if I don't know which branch to test"
 6         exit 1
 7 fi
 8 
 9 TSTAMP=`date +%Y-%m-%d-%H:%M`
10 BRANCH=$1
11 LOG=/home/francois/build-logs/$BRANCH-$TSTAMP.log
12 
13 (
14         git fetch origin                                           && \
15         git reset --hard origin/$BRANCH                            && \
16         echo =======================                               && \
17         git show                                                   && \
18         ( bundle install --without=cucumber vendor/cache || true ) && \
19         nice rake db:adgear:production:update parallel:prepare parallel:test
20 ) > $LOG 2>&1
21 
22 if [ "$?" = "0" ] ; then
23         /usr/bin/curl -s -o /dev/null -d "{\"message\":{\"body\":\"Test Suite Passed -- $BRANCH -- http://ct.local:9001/logs/$BRANCH/$TSTAMP\"}}" -HContent-Type:application/json -u 12345:X http://oursite.campfirenow.com/room/12345/speak.json
