Basic Targeting

For example, to target users who use a desktop browser, the following can be done:

    return true;

If you, for example, want to target on Firefox users using it on macOS:

if(User.browser.firefox && User.browser.mac){
   return true;

More advanced Targeting

If you want to specifically target only the cases checked by the quality assurance, it can be helpful to only allow browsers from a certain version to participate in the test.

//Target on Internet Explorer with Version from 9 and up
if(User.browser.msie && User.browser.version >= 9){
   return true;


Engine flags

If detected, one of these flags may be set to true:
