Firebug test-bot support for scheduled running of Firebug test suite.


Installing TestBot


  • You need Python virtual environment
  • In case it doesn't come within the Python package you also need Python setuptools
  • You might also need to install lxml (tested with lxml-2.3.6.win32-py2.7.‌exe). See also Known Issues on this page.
  • You might want to add following to your PATH: C:/Python27/;C:/Python27/Scripts/ (related to Python 2.7)
  • In case you don't wont to install from the source, you can just (assuming easy_install is in your path):

However, it is recommended to install from source

easy_install runFBTests
  • Download Testbot source from GIT repository:
git clone
  • Install from the source:
cd Firebug-Test-Runner
python install
  • Using testbot:
runFBTests --help
  • Run testbot:
runFBTests --serverpath http://legoas/firebug
  • Update tests from the GIT:
git pull origin master
python install


Python Virtual Environment:

Install pip and virtualenv for Ubuntu 10.10 Maverick and newer:

$ sudo apt-get install python-pip python-dev build-essential 
$ sudo pip install --upgrade pip 
$ sudo pip install --upgrade virtualenv 

Install virtualenvwrapper

sudo pip install virtualenvwrapper

Update config file for virtual environments:

gedit .bashrc

Put at the end of the file:

export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/

Reload the config file:

source ~/.bashrc

Create new virtual environment called ‘Firebug’:

mkvirtualenv firebug

Install Firebug testRunner:

sudo apt-get install python-setuptools
sudo apt-get install libxml2-dev libxslt-dev 
sudo apt-get install python-lxml

Install git:

sudo apt-get install git

Download Firebug Test Runner source:

git clone

Install Firebug Test Runner:

cd Firebug-Test-Runner
python install

Execute Test Runner:

/usr/bin$ python runFBTests --serverpath

Mac OS

This section needs to be yet revisited

Install pip, virtualenv and virtualenvwrapper:

Install GIT

Install GCC

Install lxml

Run this to make the 'mkvirtualenv' command working:

  • source /usr/local/bin/

Run test-bot:

  • sudo runFBTests --debug --serverpath http://legoas/firebug

Command Line Arguments

  -h, --help            show this help message and exit
  -p PROFILE, --profile=PROFILE
                        The profile to use when running Firefox
  -b BINARY, --binary=BINARY
                        The binary path to use. If unspecified appropriate
                        binaries will be downloaded automatically
  -s SERVERPATH, --serverpath=SERVERPATH
                        The http server containing the firebug tests
                        URI to couchdb server for log information
                        Database name to keep log information
  -t TESTLIST, --testlist=TESTLIST
                        Url to the testlist to use
  --interval=WAITTIME   Number of hours to wait between test runs. If
                        unspecified tests are only run once
  --debug               Enable debug logging

Custom Server With Tests

Testbot is using by default so, make sure this is what you want, otherwise specify your own server:

runFBTests --serverpath

Serverpath also specifies where test-bot.config (the name of the config file is hardcoded) is located. The whole path is computed as follows:

serverpath + "releases/firebug/" + "test-bot.config"

So, make sure the config file is available on your custom server.

Custom Couch DB

If you want you can set up your own CouchDB and point testbot at that one.

runFBTests --couch --database myfirebugdb

You can also specify the database in test-bot.config


In order to preview your custom database, you can configure test result viewer through URL:

Custom Test List

You can also specify a test list on the command line:

$ runFBTests -c -d firebug -s http://legoas/firebug -t http://legoas/firebug/firebug.html

Again, you can specify custom test-list in test-bot.config file


Known Issues

  • runFBTests depends on an external python package for scraping the latest firefox builds. There is a bug in this package where it won't return the download url for Firefox 3.6 on Mac OS X 64-bit systems.
  • This package also depends on lxml which in turn depends on the libxml2 and libxslt packages. You may also need the python-dev package. In linux and mac this hasn't been a huge problem (just apt-get or port install the packages if it isn't done automatically) but building lxml has given me some headaches in windows (although maybe your development environment is set up better than mine). If setuptools can't compile lxml automatically, I'd recommend installing the pre-compiled binary of lxml found here: (assuming you are using 32 bit Python) before running setuptools.
  • Do not use GIT_TAG and GIT_BRANCH fields in your custom config (needs to be fixed).

Testbot Config

Automated running of tests is configurable using a config file. Testbot currently expects this file to be available here:

The file follows syntax of INI Files. Here is an example:




Each section (there are three in this example) specifies one configuration. Name of the section should be descriptive, but isn't currently used by testbot.

  • FIREBUG_XPI - URL of Firebug XPI file used in this configuration.
  • FBTEST_XPI - URL of FBTest XPI (Firebug test harness) file used in this configuration.
  • GIT_BRANCH - GIT branch in Firebug GIT repo that is used by testbot to pull all test files. Testbot puts these files on its own web server.
  • GIT_TAG - GIT revisiion
  • GECKO_VERSION - List of Firefox versions used for testing in the configuration
  • TEST_LIST - Test suite used by test bot in this configuration.
  • DB_URL - URL of an online CouchDB where all test-results should be uploaded
  • DB_NAME=firebug2 - Name of the online database where to upload data.

Browser Window Size

Some tests depends on the browser window (with Firebug) size. For example, there can be a test that right clicks on an element in Firebug HTML Panel and opens a context menu on it - in order to execute an action. In case where the HTML Panel is too small the element doesn't have to be visible and the click wouldn't open the menu. The test would fail, even if the feature actually works.

For this reason, FBTest harness sets the browser window size to 1024x768 (as the minimum required size) and moves the window to [0, 0] position on the screen. This is done only in cases where the -runFBTests flag is specified for firefox.exe. So, users running tests as part of the daily development process are not bothered by the browser resizing.

The actual size and location can be specified in preferences:

extensions.fbtest.defaultOuterWidth [default 1024]
extensions.fbtest.defaultOuterHeight [default 768]
extensions.fbtest.defaultScreenX [default 0]
extensions.fbtest.defaultScreenY [default 0]

Example Scenario

  • As soon as you have Firebug-Test-Runner installed try to execute runFBTests --help on your command line. If you see a list of possible arguments it works well and you can proceed to the next step.
  • Now you need to setup your web server. Let's call it legoas.
  • The config file can look like as follows:
  • And finally, you just need to launch the test-bot and specify serverpath.
runFBTests --serverpath http://legoas/
  • The test bot automatically runs all tests and uploads all results the specified database.
  • Open test-result viewer and specify your database:
