Current Scenario Product Management, Designer & Developer has created a new screen with a button for an Android application. They can't decide on two Variants, which position should be the button.
Current Scenario possible button positions
Current Scenario They decide to make a user test with about six participants. => NO explicit result What now?!
Current Scenario Already a published application in the Playstore. => make a so called AB-Test It is a Test on a live application, where an amount of users get one variant and the others another. Depending on the success ratio you have now the best fitting solution.
Development Part Create switches depending on a business logic and create a proprietary solution, which is not reusable. Republish the application and hope everybody will update after the test to the final solution.
Here comes Customer's Choice
Customer's Choice a lightweight Android library for making simple usability tests on a live application https://github.com/alosdev/CustomersChoice
Usage add the library (*.jar) to your project CustomersChoice.getVariant("Variant name"); returns the chosen variant for the test and reports the test start CustomersChoice.reachesGoal("Variant name"); for reporting the goal THAT'S ALL ;)
Does it crash?
No
Minor Problem: it returns always variant 1
Configuration of Variants code JSON string in resources configuration file on the SD card configuration file in the network For testing purpose over a Broadcast Intent with overwriting.
Attributes for a Variant Name (required) startTime in Milliseconds endTime in Milliseconds spreading, int definition for ratio of different Variants {"variants":[{ "startTime": 768997, "endTime": 3787789, "spreading": [1,2,1], "name": "Variant name"}, {...} ,...]}
Extensibility You can write easily plugins for: Reporting Logging Open Source
Live Coding-/ Demo time
Demo Application
Attention make always clear what and how to report. Also gaining the results you need. source: http://i.imgur.com/h2JClux.jpg
