Manual Testing

Will you compare it to something done manually?

Manual testing adds subjectivity to QA that only a human can have. In certain cases, especially for products that are not yet fully developed, the manual approach provides the necessary flexibility without the need for an exhaustive definition.

We ensure that devices are interoperable by performing functional, performance and UX testing. We conduct dynamic tests on site, subjecting devices to handover testing, cell and network changes, and international roaming. We test 3G, 4G, 5G, VoLTE, VoWIFI and ViLTE. We also standardise SIMs from all national and international manufacturers.


In line with our methodology, we assist with the exhaustive testing of router, MiFis, PLCs and MESH network devices. Our tests include functional, UX, peak performance (Dual Band, 11n/11ac/11ax), load and security testing. We also validate third-party software agents running on the CPE.


The video ecosystem is vast and Centum Digital has extensive QA experience throughout the value chain – ranging from ingests and coding, to playback on the customer’s end device. Video testing requires a highly specialised background. That’s why we have been keeping up to date with the latest technologies for more than 15 years at Centum Digital in our continuous training process.


We are specialised in the testing of apps and web with heavy video traffic. We can start from scratch, regardless of whether there is a test plan in place or not. We work in teams with agile methodologies, ensuring that our testing adds value in each sprint.


Internet of Things environments have specific properties that require testing based on different scenarios to ensure quality. We have created our own testing methodology for IoT using a dual approach that tests first in the unit and then during integration. Download our methodology and start testing your environment professionally.




Automation has revolutionised testing. Working in short cycles forces us to speed up the QA process and this can’t always be achieved manually. This is why we’ve been developing specific tools and improving our methodology at Centum since 2015. We guarantee that you’ll only ever speak to genuine automation experts.


Cybersecurity should respect the principle of protecting what is truly important – with the necessary measures at an effective cost. We’ll tell you how it’s done.


CENTUM Digital has more than 16 years of experience in the provision of critical systems engineering services in the most demanding environments.
