For the best possible results, your test lab needs to make use of the absolute latest in cutting edge technology. Because this is the arena in which you test changes and additions to your network—including new connected devices like the internet of things (IoT)—you need to find a way to replicate existing network conditions as closely as possible. Otherwise, you might test out new service offerings or network adjustments in a lab setting only to find that your service doesn’t work correctly under real life conditions—which could result in costly delays, outages, and potential subscriber churn.
One of the biggest concerns we hear from telco operators looking to automate their tests is the relative ease or difficulty of test case scripting. Telecoms aren’t typically staffed with a huge number of technically proficient developers, and a complex testcase scripting language would therefore make it difficult to leverage non-technical personnel in the testing process. This is an eminently reasonable concern. After all, the fewer people there are in your organization who can understand the tests being performed, the more likely you are to find yourself saddled with a testing silo—which could potentially lead to slower bug fixes and poor alignment between testing and other functions.
At telco operators around the world, test engineers and operations managers are experiencing a bit of a conundrum. With networks growing in complexity by the day and manual testing getting more time consuming than ever, the need for automation is becoming obvious. At the same time, not all automation is created equal, and testers need to make sure they’re equipped with the right tools for the challenges that await them as modern networks continue to evolve.
Since the introduction of LTE in 2009, most telco operators have had to maintain three networks in parallel—2G, 3G, and LTE—with smooth interworking between the three of them, sometimes even in the course of a single phone call. Not only that, but operators need to offer their customers seamless connections with a host of other legacy systems, from ISDN to POTS. Each time the larger telco landscape gets more complex (which happens practically by the day), the presence of existing legacy systems amplifies that complexity—making life increasingly difficult for the testers tasked with verifying network functionality.
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.
MVNOs (mobile virtual network operators) sometimes get a bad rap. This isn’t entirely without reason: A recent report found that MVNO download speeds across the U.S. are 23% worse than those of their host networks on average. While download speeds for MVNO often could reach the same heights as their host networks, they tended to offer those speeds less consistently, leading to lower “consistent quality scores” in terms of meeting minimum speeds and staying below allowable levels of jitter, latency, and packet loss.
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.
As of a few years ago, more than 90% of software testers reported that they were automating between 50 and 100% of their tests. Of the survey respondents who had automated, about a quarter saw ROI immediately, another quarter within 6 months, and another quarter within a year. Fewer than 10% failed to reach ROI. Naturally, the telecom domain is its own beast, and in all likelihood the numbers for automation adoption would look a little bit less robust—but an examination of similar trends adjacent to the telco industry can still be telling for network operators and testers.
Mobile banking is not just a fad. By 2020, the U.S. is expected to have more than 160 million mobile banking users, and in the UK mobile banking is already overtaking internet banking in popularity. This could be attributed to a number of factors, from simple convenience to the increasing primacy of mobile phones in general—but whatever the cause, the implication for banking and financial services businesses is pretty clear: you really need a robust mobile application that your subscribers can access on the go.
Let’s say you’re migrating all of your subscribers to a highly redundant HSS database. You know it’s going to be a long process, but you want to set an ambitious deadline and perform the migration before your next quarterly all-hands meeting. As such, you put together a list of the things that are most likely to cause delays. And what should be at the top of that list? Depending on how your current test operations function, service verification could be your prime suspect.
