Expleo, the technology partner for innovative companies, today announces details of its role in the launch of the StopCOVID NI contact tracing app, built to have interoperability with the COVID Tracker app deployed in the Republic of Ireland. Expleo carried out extensive quality testing on the app, the world’s first cross-border tracker device aimed at stopping the spread of COVID-19.

The StopCOVID NI app was built using the same technology and design as the Republic of Ireland’s COVID Tracker app, which Expleo’s quality assurance team was also heavily involved in. For the Northern Ireland app, Expleo’s team carried out more than 1,000 hours of testing and was responsible for ensuring that it was user-friendly, reliable and capable of sending and receiving anonymised data to and from both the Northern Ireland and Republic of Ireland versions of the app. As a result, users will be notified if they have had close sustained contact with a confirmed case of COVID-19, regardless of which application they are using.

Expleo’s expert team carried out multiple processes and strategies to ensure that a user’s surroundings did not negatively impact the performance of the app. Testing was also carried out on public transport to ensure that users only received notifications when appropriate.

Quality tests included:

  • Performance testing – Expleo’s quality assurance and quality engineering teams carried out load testing on the app to ensure that large volumes of people could download it at the same time without causing it to crash.
  • Exposure Notification Distance Testing – As devices have varying Bluetooth signal strengths, Expleo tested varying attenuation values to maximise compliance with requirements.
  • Database Validation – Testers ensured that users’ anonymised data, gathered from downloads and registrations, was populated in the database without interfering with the anonymised data of other users.
  • Graphical user interface (GUI) testing – Expleo tested the look and feel of the app, ensuring user-friendly navigation; the correct and reliable function of buttons; and that all content and text matched requirements.

Dan West, Chief Digital Information Officer for the Department of Health, Northern Ireland said: “The StopCOVID NI app is an essential next step to successfully reopening Northern Ireland. The fact that this application can operate in conjunction with the COVID Tracker app in the Republic of Ireland offers even more protection – particularly for those living in the border regions.

“With consideration for GDPR and privacy concerns, there was obviously a stringent set of requirements for both these apps. Expleo’s knowledge and expertise ensured that both applications were completed in compliance with all regulations.”

Scott Armstrong, Director, Expleo, said: “COVID-19 has caused havoc for people and communities across the island of Ireland. After our involvement in the successful launch of the Republic of Ireland app, we are honoured to have the opportunity to use our extensive experience in software testing and quality assurance to also support Northern Ireland’s fight against coronavirus.”

“We have been very pleased to see such high volumes of people downloading the Republic of Ireland’s version and we hope that the app will be similarly embraced in Northern Ireland so that we can all work together to stem the spread of COVID-19.”
