Coverage matters when considering a testing partner.
At Testlio, we think of test coverage on three dimensions:
1. Devices: The real hardware that our human testers work on matters most to our clients. We never simulate or emulate devices and conduct app testing on a nearly infinite combination of platforms and devices.
2. Locations: In many cases, where we test is critical. With testers in nearly 100 countries around the world, including thousands in the US, we can bring people to precisely the place you require for location testing.
3. Languages: Our testers speak, and can test in, more than 100 languages. When you need linguistic expertise, coupled with functional, localization, and other QA testing services, Testlio can help.

Locations Covered
Location is often paramount when it comes to test coverage. Today’s test coverage strategy must take into account the evolving ways consumers engage with technology. Apps increasingly meet consumers with a frictionless experience from the digital realm into the physical world. At work, home, the mall, while traveling, or catching a game at the ballpark.
