Telemetry Experiments

Getting started

  • clone the repo http://hg.mozilla.org/webtools/telemetry-experiment-server/
  • create a new folder under experiments/ for your new experiment
    • it is highly recommended that you use `hg cp` from an existing folder (this makes review easier as it's able to track the changes made to the boilerplate files)
    • e.g.
      • cd experiments; hg cp e10s-beta45-withoutaddons my-new-experiment
    • use a descriptive folder name to highlight the feature, channel and version
  • the main experiment code lives in code/bootstrap.js

Manifest file

  • the file under experiments/your-experiment/manifest.json contains the configuration details for your experiment
  • the "sample" value, for example, tells the percentage of users (matching the other criteria) that will receive your experiment

install.rdf file

  • the file under experiments/your-experiment/code/install.rdf file contains details about the experiment add-on. The <type> value for all experiments should be 128. Note that an add-on with type=128 does not work by drag'n'dropping it to Firefox like a regular add-on (it needs to be loaded by the experiment system)

Building the experiment

  • To build the experiment, you just need to create an .xpi file with your bootstrap.js and install.rdf files. Put this xpi in the root of your experiment folder (i.e., experiments/your-experiment/)
  • If you grab one example Makefile from the tree, you just need to use `make experiment` and the xpi will be created for you
    • note that the xpi is created under a build/ folder. You need to move it the proper location (the root of your experiment)
