All the benefits of simulators with no required setup

Waldo makes it easier for iOS developers to interact with virtual devices. Tap, shake, scroll, rotate, and  swipe through your application like the phone is in your hand. As soon as you upload a build, your desired device is ready to go, and always in a fresh state.

Unlock concurrent testing across custom device settings

Significantly reduce the time it takes to run a comprehensive testing suite across multiple devices. Waldo supports simultaneous tests across various device configurations, so you can easily identify and replicate issues impacting certain users.

Work within your existing development framework

React, Swift, Ionic...Waldo works with your existing tech stack to make automated testing a seamless part of your process. Upload an existing emulator or simulator build and start building your tests in minutes.

What is a simulator in mobile app testing?

A simulator provides an environment that has all of the configurations and known software settings of a device. This allows developers to test their mobile applications thoroughly and ensure the functionality is consistent in a “virtual-native” environment, especially when interacting with external applications.

Simulators can help you test important transaction points in your application, the read/receive ability of the app, and allow you to view how device settings (screen resolution, screen size, etc.) impact the visual display of the app.

Why test on a mobile simulator instead of a real device?

Mobile simulators provide a faster and infinitely more scalable option for iterative testing during development. This can help you screen for various bugs and regressions more efficiently.

Real devices are still an important part of testing, allowing you to capture things that simply cannot be simulated: like battery health/levels, connection latency, or storage issues impacting the performance of your iPhone or Android device.

What to look for in a mobile simulator for testing?

Something that makes your life easier from setup through testing.
An ideal mobile simulator has no intense coding, scripting, or time consuming, heavy-lift maintenance required. Simulators should improve your efficiency: meaning from setup through testing your life should get easier.

A tool that enables concurrent testing on multiple device types.
Your end users will be accessing your work on a variety of device types. Your mobile simulator should help you catch bugs quickly and in-cycle by empowering the team to run multiple tests across multiple device types.

Something that positively impacts your server expenses.
Testing shouldn’t be a bottleneck or a cost center…it should be a competitive advantage! Mobile simulators can and should reduce the costs usually associated with testing while still giving you valuable insight into regressions, bugs, and other unwanted behavior.
