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 comesCustomer'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
Attention
make always clear what and how to report. Also gaining the results you need.
