Add to Try Server Automated Testing Support

Introduction

We are trying to add to a Try Server, that will be set up at Seneca, automated testing support (TUnit (make check), mochitest, reftests, crashtest)

People

  • Armen Zambrano G. (armenzg) #seneca channel
  • People from Mozilla helping me: Rob Campbell, Robert Helmer, Ben Hearsum, Robert Sayre, Mike Shaver, Adam Delyea and Dave Humphrey

News

  • 16-Apr-2008
    • Updated wiki page
    • Reftests was not running properly (it timed out - stdio - exit code -1 after 1200secs)
    • Changed DISPLAY to :2 and build 45 shows that we got GREEN with reftest
    • I have to add cronjob to run perl processchange.pl every 2 mins
    • There are 2 linux slaves on vmlinux1.hera
    • To upload a patch you must use an LDAP account (I have to investigate this)
  • 15-Apr-2008
    • The try server with unit tests runs properly
    • Forked on tryserver account, sendchange.cgi and sendchange-ui.pm
    • Forked on buildmaster account, processchanges.pl and download.log
    • All of the previous files have been copied with suffix _test
    • Created on tryserver and buildmaster the folder "patches_test"
  • 12-Apr-2008
    • We can now run the Unit Tests on vmlinux1.hera which is a virtual machine using the CentOS 5 image
    • We needed a DISPLAY to display in the unit tests, I set on the steps the value DISPLAY=:0
    • We needed to start an X server; I found the way to do it was startx(maybe xstart, not sure), which started the desktop environment. Used ps -ef | grep X to find out.
    • There is X :0 (started by root), Xvnc :1 and Xvnc :2
  • 21-Mar-2008
    • Access to the waterfall view of Hera's buildbot and force a build by selecting lin-test link that shows you the builder's status
    • When forcing a build I do not get immediate builds
    • The tests are not running properly (Error: no display specified)
    • I do not know why do I see the code been build with gmake
    • Links to see some of the forced builds I did: #13 #14 #15 #16 #17
  • 18-Mar-2008
    • Granted access to the Hera server
  • 16-Feb-2008
    • There will be no release this week, since I have been working on the Buildbot and Cairo project
    • It seems that Adam has been setting up the first node and the slaves during this week. I will probably have an account next week.
  • 1-Feb-2008
    • Since I could not wait for the Seneca Hera Try Server to be ready, I decided to set up buildbot on my laptop and so far is working
  • 29-Jan-2008
    • SERVER NEWS: The main OS (CentOS 5.1 and Windows 2003 Server) are installed. Once they are configured we will duplicate them to the rest of the nodes.
    • Soon the server will be completely running and we will have access to it
    • I have added a repository svn:Seneca Hera Try Server - automated-testing integration an I am modifying the master.cfg file to meet the purposes; It is based on buildbot-configs/testing/unittest/
    • I might set up this Saturday my own try server at home
 
mozbuild.py and the test suites classes defined
  • 18-Jan-2008
    • We are waiting for the Buildbot Farm to be set up at Seneca
    • At this point I have been able to run "make check" tests and mochitests. Explained in blog how to do this
    • Read Buildbot manual, discovered that I have to write some Build Steps but there's some configuration done by the community (check links section)

Releases

NOTE: I did not work on this project for a month but instead I worked on the Cairo project

Release Apr. 9th

  • You can upload a patch through sendchange_test.cgi. You can also upload another .mozconfig, which overwrites default .mozconfig. Please specify the proper patch level (we suggest to create diffs from mozilla/ and select 0 as the patch level)
  • Wait for a couple of minutes and refresh [1] until you see your build running
  • I would like to show the steps to make everything happen in your machines but I have not setup this server. Assuming we were in the same environment/setup:

Steps

How to setup a tryserver ([2])
Setting up the buildmaster # cvs -d:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -d tryserver mozilla/tools/buildbot-configs/tryserver # cd tryserver (This brings env.py, tryserver/steps.py and unittest/steps.py with others) # cvs -d:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -d buildbotcustom mozilla/tools/buildbotcustom # cvs -d:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -d processor mozilla/webtools/buildbot-try/processchanges.pl # mv processor/processchanges.pl . # rm -rf processor

  1. TBA - IN HERE TO BE ADDED STEP TO CHECK OUT MASTER.CFG

Release Apr. 5th

  • Nothing to release, I have only been able to run build with tests (with warnings) in my designated

BRANCH of slaves

  • The form to upload a test to the tests branch has been created

Release Mar.21st

  • Blog post about setting the automated tests on Hera - armenzg: Sess16 - Automated testing on Hera
  • The files that have been modified in Hera are: master.cfg (to add the steps to do the tests), mozbuild.py(contains classes that group few steps into one and does more intelligent steps), mozconfig-linux-tests(which contains the .mozconfig for the lin-test builder) and env.py (which contains MozEnvironments['centos'] environment variables)
  • Read about some errors encountered in the NEWS section in this page

0.5 release

This release was meant to just allow buildbot to run tests steps after a build. In Hera should do the same and also allow the "try-server" way.

Steps

NOTE: I assume you can build mozilla firefox. This steps are to build on Linux (my flavour is Ubuntu7.1) 

# sudo apt-get install buildbot
# buildbot --version
Buildbot version: 0.7.5
Twisted version: 2.5.0
# buildbot create-master ~/BuildbotMaster
# buildbot create-slave ~/Buildslaves localhost:9989 slave1 slavepassword1
# Untar this BuildbotMasterArmen0.5.tar.gz file in your ~/BuildbotMaster directory
# buildbot start ~/BuildbotMaster
# buildbot start ~/Buildslaves/
# open your web browser and open this URL http://localhost:8010, you should see the results

NOTE 2: There is more explanation in these two posts (Sess10 and Sess11 NOTE 3: The only way for me to assure that these steps works for everyone, I would have to try it from a clean install of Ubuntu

Info

  • You can see which tasks get done at the bottom of this page
  • I will add the instructions on how to set up a Buildbot try server when I do it at my house
  • The image on the side shows the classes that are defined in the mozbuild.py which are later on used as Buildsteps on the master.cfg file
