Faker is a tool to generate fake data.
https://github.com/fzaninotto/Faker support was added to Tiki18 as one of the Packages, allowing to generate fake tracker items to facilitate testing tracker or Unified Index performance, for instance.
You can use it through the Console command line script.
php console.php faker:tracker [-f|--field [FIELD]] [-i|--items [ITEMS]] [-r|--random-status] [--reuse-files [REUSE-FILES]] [--] <tracker>
Command to create 5 new items, with random tracker item status (open, pending or closed), on tracker 1:
php console.php faker:tracker -i 5 -r -- 1
