Mobile testing has been a long and arduous process for many companies across the globe. Testing an app on hundreds of devices is a bit mind-boggling. Many companies have hesitated to adopt these ideas as they are caught in a vicious circle. They cannot decide whether to use a mobile testing lab or test their apps on real devices.

What is a Mobile Testing Lab?

Facebook’s mobile device testing lab at the Prineville Data Centre has Android and iOS devices that test Facebook applications and Instagram. Thousands of mobile devices are racked for testing apps that would soon launch into the real world. The high-tech lab is remotely operated and specifically targets device behavior regarding speed, memory usage, and battery consumption.

This spirit of delivering the best user experience amidst which Facebook came up with a multimillion-dollar mobile testing lab is worth the applause. A dedicated mobile testing lab will go a long way if you share the same business goal.

In this blog, we will explain how mobile testing labs work and how you can use them to test your mobile device.

The Need For Mobile Testing Lab

A reliable testing facility ensures that no stones are left unturned – this is possible when you run your app on all possible devices. Here are the key reasons why it makes sense to have a dedicated mobile device lab:

  • Find and fix bugs at the earliest
  • Reduce the time-to-market
  • Launch more features per app release
  • Cover all possible mobile devices
  • Agile and DevOps methodology

Why do Developers and Testers Prefer Mobile Testing Labs?

Mobile phones have evolved immensely since they first became a part of our daily lives. With OS, screen resolution, device sizes, and overall design varying from one brand to another, developers and testers must confirm that their apps are compatible with all the different mobile phones.

However, it is nearly impossible to own all these smartphones and keep upgrading to the new ones when they are released just to test a few applications on them.

And thus, comes the need of mobile device testing labs that allow the developers and testers to validate their applications on cross-platform devices, including Android and iOS. Using such labs is useful for testing the apps on real-devices to identify potential issues in the system.

The mobile testing lab setup is truly a great option for developers and testers to ensure that their apps do not encounter bugs once they have gone through rigorous testing.

Key Considerations to Keep in Mind While Creating a Mobile Testing Lab

1. Compatibility

Speaking of Android OS, in 2019, there were around 2.5 billion devices. These devices ran on various OS versions, screen resolutions, and network types. So, your lab must be capable of embracing the maximum number of devices.

2. Device Infrastructure

Once you have chosen your target devices, consider the architectural aspect of your hardware. Having solid and reliable servers to manage mobile devices and execute test scripts would be best. These servers should be able to collect the requests by Dev and QA teams, process and execute these requests, as well as deliver the results & reports to the respective stakeholders.

3. Internet and Power Supply

These are the lifelines of any test lab. As the devices in a test lab add up, the WiFi bandwidth must also be updated. You would struggle with timeouts or slow server responses with weak Wi-Fi points. Next comes the batteries of your mobile devices. Batteries overheat and degrade over time which may need regular replacements and repairs.

4. Automated Testing

The clear takeaway of embracing automation testing for mobile apps is that you simultaneously test various devices, operating systems, and network types. A single test script lets you save on your QA spending, enhance coverage, and fasten the bug resolution.

5. CI/CD Integration

Today, almost every online business has a mobile app. For some, the mobile app is their first step or the only platform where they interact with their new and existing customers. To streamline the regular app updates, it is imperative to adhere to Continuous Integration (CI) and Continuous Delivery (CD) protocols.

Mobile Testing Lab – Is the Investment Necessary?

Not really. 

A dedicated test lab only makes sense when you have a realistic budget and infrastructure at the place. You need to be prepared for the fact that your mobile device may get outdated within days and you would have to update your repository every now and then.

Here is a quick rundown of mobile testing on real vs virtual devices:

 CriteriaReal DevicesSimulators & Emulators
CostVery costlyMinimal cost
Reliability Exhibit accurate resultsMimics real devices and provides reliable results
ProcessingTesting is much fasterTesting is slower
DebuggingDebugging and capturing defects is tricky Easy to debug and capture defects
Cross-Platform TestingTime-consumingNeeds less time

Hence, for many ‘practical’ reasons, building your own data center with physical devices is not ideal. New devices will launch more rigorously in the near future and you would always find yourself struggling to keep your hardware up to the minute.

Why Does Cloud Testing Make Sense?

Mobile phone manufacturers compete with each other to launch feature-rich devices. This is a treat for the users; these regular enhancements make it quite a task for testing companies to validate the applications in the dynamic ecosystem.

Investing and maintaining a dedicated lab is not feasible. A reliable and convenient alternative to achieve quality goals is a cloud platform. Cloud-based testing offers access to a large or possibly every device and network type for application testing. And with the rapidly evolving mobile technology, the need for mobile cloud solutions will rise.
