A case for humans.

Testing in the wild captures real-world user experiences – browsing, network connections, and infinite devices and operating system combinations.

Testlio’s global network of 10,000 expert testers with more than 1,200 real device/OS combinations can catch and report details missed by automated runs. They mirror your customers’ locations, network connections, and device/OS combinations. And, catch issues like:

  • Network connectivity issues – How do your web and mobile apps respond when your users lose service?
  • Truly accurate displays – What does your web and mobile app look like on a real screen from device to device?
  • Location – Does your digital offering change depending on where it’s used?
  • Physical experiences – Can your apps take pictures and scan QR codes with ease?
  • Interactivity with other apps – Does your web and mobile app switch cohesively between different programs like the app store and photos? Are pop-ups negatively affecting your UX?
  • Interactivity with hardware – Are your apps swiping and dragging like you want them to?
  • Context-driven results – How do device-based variables such as battery life affect your user experience?

A case for machines.

Automated testing on real devices enables you to conduct repeatable tests much faster.

  • Less expensive than managing an in-house device lab.
  • Debug issues faster.
  • Gain immediate access to various devices.
  • Test on new and legacy browser versions
