=== Using a local Talos repo ===
=== Testing Locally ===
 
If you are making changes to Talos itself, you will want to test your changes by building and running your local copy of the Talos source code:
 
'''Clone Talos:'''
 
hg clone http://hg.mozilla.org/build/talos
 
'''Run the [http://hg.mozilla.org/build/talos/file/default/INSTALL.py install script]''':
 
cd talos
python INSTALL.py
# (Ignore errors like "fatal error: 'yaml.h' file not found. To get rid of this error message you can download and install PyYAML from http://pyyaml.org/wiki/PyYAML but it is not necessary.
 
The INSTALL.py script creates a [https://developer.mozilla.org/en/Python/Virtualenv Virtualenv] in the same directory as 'INSTALL.py' and installs the talos [https://developer.mozilla.org/en/Python#Python_packaging python package] into the virtualenv, including its [https://wiki.mozilla.org/Auto-tools/Projects/MozBase MozBase dependencies] via 'python setup.py develop'. ''(Alternatively, you can perform these steps yourself.)''
 
'''Activate the virtualenv:'''
 
''(on windows):''
Scripts\activate.bat
 
''(on osx/linux)'':
. bin/activate
 
'''Unpack a copy of firefox somewhere''' (for this example, we'll use `which firefox` as if firefox was on your path).
 
'''Set up a webserver''' if you're not using the '--develop' flag. (WE STRONGLY RECOMMEND USING THE --develop FLAG.)
 
* Set up apache or similar webserver to have http://localhost -> the talos subdirectory of the talos checkout.
* Alternatively you can use the --develop flag to PerfConfigurator which configures to use a python webserver, [https://github.com/mozilla/mozbase/tree/master/mozhttpd mozhttpd], as shown below
 
'''Run the tests''':
