Let’s say you have a small system whose functionality you want to test, and you determine that there are five distinct use cases that require verification. As a technically-adept test engineer with a fair amount of programming skill, what do you do? In all likelihood, you simply script up each test case individually, so that for each use case there’s a unique piece of code that needs to run in order to make sure that everything is working smoothly. This makes sense, and as test automation has become more common (in some sectors, anyway), we've seen a lot more people doing just that. For a limited number of test cases, this is probably the smart thing to do. But what happens when it’s not half a dozen use cases that require scripting, but hundreds or thousands?

Are Tests Run on Rooted Devices Reliable?

Sometimes, the OS that comes built into an Apple or Android device can seem like it’s actively preventing you from doing what you want. And, to some extent, that’s true—Apple only lets you download the apps that are in the App Store because there are some actions that they want to prevent you from taking. As an end user, this often seems capricious and arbitrary. As a tester, it feels similar: why shouldn’t you be allowed to make the necessary changes and additions to the phone’s functionality to make end-to-end testing easier?

If you’re a telco test engineer, you know that the world of telecommunications is getting more complex by the day. Your service needs to integrate with more devices than ever, and you still have to maintain interworking with any number of legacy systems. This is driving an increase in the number of test cases that require verification, and also a renewed push towards automation across the field. Whether you’re selecting an automation solution or simply trying to keep your testing process as efficient as possible, it’s important to keep tabs on the new challenges and opportunities that are likely to be coming down the pike.

Legacy Telephony: the Importance of Backward Compatibility

Backward compatibility is a noble goal for any communication system. For telecom networks in particular, it's an important part of providing seamless coverage across legacy platforms, which means you can keep customers happy without forcing them to upgrade their service constantly. By placing an emphasis on service in this way, you can help protect revenue over time. That said, ensuring legacy integration can often provide challenges for operators.

How To: Enterprise Mobility Testing

One of the most significant ways in which the rise of mobile phones and laptops has changed the business world is encouraging a tremendous increase in mobility. Not only are employees at many businesses able to telecommute more easily than ever before, folks traveling for business are able to stay connected so effectively that it can feel like they’ve never left the office at all. For obvious reasons, this makes life easier and more pleasant for a lot of folks, all while helping to make truly global enterprises more connected than ever. The cost of this increased freedom, however, is a subsequent increase in complexity for telco operators.

The pace of technological change has been speeding up at a seemingly unprecedented pace in the 21st century, and in few places is that more evident than in the telecom sector. Just a few short decades have taken us from what would now be considered legacy telephony through 4 generations of broadband cellular networks—with a fifth on the way. In the meantime, things like VoLTE and VoWiFi have become commonplace offerings in your typical telco operator’s portfolio. The race to provide new service offerings and update the functionality of existing ones is underway, and it’s already pretty heated.

Why Is Beyond End-to-end Testing for IoT Devices Important?

It’s become a fairly well established stereotype that people in many parts of the world can’t or won’t look up from their smartphones. Back in the day, the only reason to look at or think about your telephone was because it was ringing or because you intended to make a call fairly imminently. As a consequence, if a signaling error was preventing your home phone from completing calls as intended, you might not even notice for a few days. Nowadays, on the other hand, if your LTE service is interrupted for two or three minutes you’ll probably notice immediately—and you’ll be none too happy about it.

How To: Verifying Roaming Service

One of the top goals that every telecom operator aspires to is consistent service, and a big part of that consistency is tied to how well you can coordinate with other networks to offer high quality roaming service for your customers. Perhaps more so than in the past, users don’t want to comb through a lot of fine print about where their in-network coverage begins and ends—they simply want to be able to use Gmail while they’re out and about in the world without experiencing any glitches or service anomalies.

What Does End-to-End Testing Mean for Telecoms?

Sep 19, 2019 9:00:00 AM / by Thomas Groissenberger posted in Network Testing, Automation, End-to-End Testing

The digitization of telecommunications has led to the adoption of many software testing methodologies, including end-to-end (E2E) testing. Sometimes confused with system testing, E2E testing goes much farther, validating the interoperability of different network components and their complex interactions.

Outsourced vs. In-house: Which Testing Method is Better for Telecoms?

Sep 17, 2019 9:00:00 AM / by Thomas Groissenberger posted in Automation, Automation ROI

At some point in their growth and development, most businesses regardless of industry eventually reach a point where they realize they can’t do it all themselves. Either they need help marketing their product, or some of their more tedious HR tasks could be outsourced, or their testing operations could be made more efficient by partnering with an outside agency. Some companies outgrow this stage and ultimately reclaim their ability to do things in-house, but others continue to grow with their partnerships in tact. Neither approach is necessarily better than the other—but they both present distinct pros and cons.
