Let’s say you’re planning to migrate to a new high-redundancy CS core network—what’s the first challenge that comes to mind? For many of you, it might be network architecture. The structure of modern telco networks is increasingly complex, and any new network rollout is going to be much more involved as a result. To wit, you’ve got to make sure that you’re setting up the core network protocols correctly (in accordance with the 3GPP standards), that your network can interconnect successfully with other networks, that it has functioning access layers for end users devices, and much more.
At most telco operators, end-to-end tests are the dream. Given that each new network update or service offering potentially requires dozens of testcases verifying conformance, acceptance, functionality, and performance, true end-to-end tests that validate the entire functioning of the network from the end-user’s perspective are daunting and often difficult to accomplish (especially if you’re testing by hand). As such, your average network tester might balk at the idea that end-to-end testing wasn’t enough to ensure high network quality—considering that going end-to-end is no mean feat in itself.
Every year, Gartner gives a rundown of what it predicts will be the major strategic trends for companies to explore in the coming year, and 2019 was no different. The leading research and advisory firm has some lofty expectations for the year ahead—including practical blockchain applications, an increase in distributed cloud computing, more focus on transparency, and the democratization of expertise, among others—but one of their new strategic trends in particular caught our eye at SEGRON: hyperautomation.
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?
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.
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.
We talk a lot on this blog about end-to-end testing, and we don’t plan to change that fact any time soon. Why? Because end-to-end still represents the only testing methodology that puts the needs of end-users at the center of the testing process—and end-user experience is only becoming more important in the ever-changing telecom domain. So, naturally we want to give our readers the tools and information they need to outline end-to-end tests within their networks in order to maintain a high quality of service. That’s why today we’re taking a deeper look at some specific instances of end-to-end testing, in order to provide a more concrete idea of what this methodology looks like in practice.
We’ve talked a little bit already at this blog about how automated testing is becoming a virtual necessity for telco operators. As increasing device fragmentation and the proliferation of different protocols continue to inflate the number of use cases that require testing, human testers are struggling to keep up. But, if you’re reading this, you probably know all that. More than that, you’re probably almost ready to take the plunge and seriously consider an automated testing solution for your business. The question at this point is, how do you choose the right tool?
Automation is often treated like a magic bullet, a cure-all for increasing demands on testing personnel who face new network quality concerns, additional devices, and other challenges every day. However, the truth is that automating any process, especially a critical one like network testing, is fraught with pitfalls. These five best practices can help ensure the success of network testing automation.
End-to-end testing—it’s all the rage right now in any number of industries, and with good reason. As global technologies become more connected and more thoroughly interwoven into the fabric of society, more thorough and efficient testing will become not just a luxury, but a necessity. As such, it should come as no surprise that a number of testing automation providers have cropped up in the past few years, covering everything from software security to telecoms. This, too, makes sense on the surface: how different could testing solutions for different industries really be? If you can automate verification for a new social media platform, why can’t you do the same for VoIP verification?
