In today’s connected environments, digital signage has evolved far beyond marketing screens or passive displays. It now plays a mission-critical role in delivering real-time information, guiding customer journeys, and powering business operations across sectors including retail, transport, workplace and hospitality. At the heart of this infrastructure is Engage Suite, ZetaDisplay’s proprietary CMS platform responsible for ensuring that content is delivered reliably, securely, and at sca
Behind Engage Suite’s performance is a structured, expert-led testing function, headed up by Test Manager Katjana Brandt. From software updates to player firmware, from complex data integrations to hardware compatibility, ZetaDisplay’s test and QA processes ensure that every piece of the platform works as expected.
A testing function built for modern digital signage
Testing software designed for digital signage requires a broad lens. It’s not only about validating features or checking interfaces. It involves understanding how content is delivered across different hardware models, firmware versions, operating systems and browsers. It involves ensuring that updates roll out smoothly across thousands of installations. And it requires a structured approach to quality that supports continuous development.
Katjana explains that the team covers both manual and automated testing across Engage Suite’s backend, frontend and hardware integrations. Their work includes API testing, firmware compatibility checks, regression testing and performance evaluation across global locations. This ensures Engage Suite behaves consistently and reliably, whether a screen is operating in Stockholm, Tokyo, or New York.
A mature, structured and future-focused approach
When ZetaDisplay first consolidated its software portfolio, testing needed to evolve into a coordinated function. Today, it operates with clear processes, specialized tooling, and integrated workflows that support the entire development organisation.
Testing is embedded throughout the software delivery lifecycle. Developers perform initial tests in controlled environments, after which the QA team validates functionality in dedicated PR environments, combined environments and full test releases. Automated regression tests run alongside manual checks, ensuring a holistic view of stability and performance.
To broaden coverage, ZetaDisplay has invested in tools that allow automated testing across multiple browsers and operating systems, reflecting real customer usage patterns. This significantly strengthens coverage and ensures Engage Suite performs well on the technologies most used across our customer base.
Security, performance and real-world reliability
As Engage Suite evolves, the testing strategy evolves with it. In recent years the function has expanded into areas such as:
- Security testing coordinated with external specialists, ensuring data protection and system resilience
- Global performance monitoring, evaluating response times from various regions
- Hardware compatibility validation, particularly as player software grows more advanced
- Automation expansion, allowing a broader set of test cases to run nightly
Each of these areas supports ZetaDisplay’s commitment to delivering dependable, enterprise-grade digital signage solutions for mission-critical environments.
Developing skills and supporting future talent
Quality assurance requires specialized technical competence, and we are committed to strengthening the field. The testing function collaborates with programmes such as Jobbsprånget and EC Utbildning to provide placements and long-term opportunities for emerging talent. Several testers at ZetaDisplay began through these pathways and have since grown into key contributors within the organization.
The team values structured methodologies, including ISTQB terminology, Xray for Jira-based test case management, and frameworks such as the Agile Testing Quadrants. This ensures testing remains consistent, measurable and aligned with industry standards.
A critical pillar of Engage Suite’s success
Reliable signage is central to the customer experience. Whether displaying real-time transport information, promotional campaigns, or workplace communication, screens must work every time. Engage Suite’s testing function ensures that reliability.
Through a combination of structured processes, expert competence and continuous improvement, the testing team plays a crucial role in ensuring ZetaDisplay delivers stable, modern and future-ready digital signage solutions.
