Experiments

Overview

Experiments are how you use your feature flags to expose your target groups to different application behaviors.

Creating an Experiment

  • Goto Rollout's dashboard, on the left sidebar, click on Experiments, at the very top of that list. This will bring you to the Experiments page.
  • This will show you any experiments that you have defined.
  • To create a new experiment, click the Create Experiment button at the top, right-hand corner of the screen.
  • This will launch a dialog that walks you through experiment creation.
  • First, under Flag, choose your platform, and then select the flag itself. The list of flags is generated automatically after you add a flag to your code base and run your application.
  • If you want a refresher on how to add a flag to your code, please see: Creating Feature Flags
  • Next, pick a name for the experiment, and type that under Name.
  • When you're ready, click the Set Audience button, which will finish the creation of the experiment and send you to the Experiment Details screen, where you select the deployment rules.

Deleting an Experiment

  • Goto Rollout's dashboard, on the left sidebar, click on Experiments, at the very top of that list. This will bring you to the Experiments page.
  • From this page, pick the experiment that you wish to delete, and click it.
  • Now, click on the Delete Experiment tab at the top, next to Settings.
  • You'll be taken to the screen for deleting an experiment, which gives you a warning about what this implies: that deleted experiments cannot be restored.
  • If you wish to proceed, click the red Delete button. You will receive another warning in the form of a modal dialog.
  • This will return you to the Experiments page, and you will notice that your experiment is now gone.

Modifying Experiment Settings

  • Goto Rollout's dashboard, on the left sidebar, click on Experiments, at the very top of that list. This will bring you to the Experiments page.
  • Select an experiment
  • To get to the experiment settings, click the Settings tab at the top, next to Audience.
  • To set your experiment's name, type in the Name text box. This cannot be empty.
  • You can change the Stickiness Property of an experiment, before changing the stickiness property, please read: Stickiness Property
  • If you wish to add a description, enter that in the Description field.
  • You can also look at the experiment's flag in the Flag text box. You cannot, however, edit this field.
  • Finally, at the bottom, you can archive this experiment by clicking the Archive Experiment link and clicking the Archive button in the warning dialog that comes up.
  • Archiving will cause the experiment not to appear in the active experiments on the Experiments page. This is usually used for experiments which are in a steady state, either fully deployed or fully rolled back.
  • When editing the settings for an archived experiment, you will see an Unarchive Experiment link. You can click this to make the experiment active once again.
  • When editing the settings, you do not need to take any kind of explicit action to save; your modifications are saved automatically.
