We live in a globally connected world, and yet the differences between cultures run deep. If your site is available worldwide, you have to account for them, and it goes well beyond translated text.
Localization (often shortened to L8N) is about handling differences in number formats, currencies, and more. In Germany, for example, dates follow the DD/MM/YY pattern and numbers are written as 1.234,56 rather than 1,234.56. Localization testing checks whether your site handles all of these cultural and linguistic differences correctly.


Multinational companies cannot afford to get localization wrong. Mistakes risk offending users, or simply making your content unreadable to a global audience. If a film releases on November 5th, it matters enormously whether that appears as 5/11, 11/5, or 11.05.
Units bring their own traps. A US pint, for instance, is about 20% smaller than a British one. And the real challenge is the sheer number of variables involved, on top of confirming that your site defaults to the right localization settings on its own.
Functionize makes localization testing genuinely straightforward. Upload a spreadsheet containing every variable you want covered, and the system works through each test, validating against the correct data for each locale. Prefer databases? Drive the same tests from SQL instead.
Every Functionize test also runs from our Test Cloud in its own virtual machine, and can launch from anywhere on the planet. That makes it easy to verify your application picks the correct L8N defaults for each region.


Setting up data-driven testing is usually a nightmare. You have to figure out how to reach the data source, label every item, and wire it all into your scripts.
Functionize Test Data Management (TDM) turns that into a few clicks, and an AI-powered auto-mapping mode does most of the wiring for you.
Nothing beats testing from a real machine in the target country, but maintaining hardware around the world is not realistic for anyone.
The Functionize Test Cloud gives you the next best thing: virtual machines distributed across the globe, so your tests experience your application the way local users do.


Chances are your app relies on one or more plugins or other third party content, and it is vital to confirm that this content also picks up the correct locale.
Unlike traditional test scripts, Functionize tests have full visibility into embedded content, so you can fold it into every localization test you run.
