You can add a URL parameter ?pk_ab_test=$variationName to any URL to force the activation of a specific variation. Make sure to replace $variationName with the name of a variation. If you run multiple tests on the same page, you can activate different variations by specifying the variation names comma separated: $variationName1,$variationName2.

This is useful when you are integrating an experiment and you want to test each variation or when you need to share a URL for each variation with your colleagues to get an approval before running an experiment.
