0manual evidence

Audit-ready reports generated automatically every run

Rail vehicles run multiple software surfaces: driver advisory displays, passenger information systems, door control panels, and connected maintenance dashboards. Each surface is developed by a different supplier, runs on different hardware, and must be validated across configurations. AskUI unifies this into a single test suite that validates the entire system before every software release.

The challenge

Why existing tools fall short

Embedded displays have no test hooks

HMI panels run proprietary or locked-down operating systems. No DOM, no API, no accessibility layer. Agentic interaction is the only viable approach for test automation.

Hardware variant matrix

The same software must work across multiple configurations with different display sizes, hardware revisions, and supplier setups. Each variant is validated manually, or not at all.

Cross-system scenario gaps

A driver action on one display must propagate to the passenger information system and door control. Testing each system in isolation misses the integration failures that matter most.

Evidence assembly is manual

Every release requires structured test evidence across all systems. QA teams compile screenshots, logs, and results manually, adding weeks to every validation cycle.

What AskUI delivers

One suite. Full coverage.

Cross-system validation

Validate that actions on one system produce the correct response across all connected surfaces.

—Driver input → verify passenger information update
—Door release → verify status on driver display
—Alarm event → verify propagation across all systems
—Single pass/fail covering the complete chain

Variant matrix testing

Run the same test suite across every hardware configuration without per-variant customization.

—Multiple display sizes and hardware revisions
—Different supplier panel configurations
—Automatic adaptation to screen layout differences
—Full variant matrix covered overnight

Agentic HMI interaction

AI agents interact with embedded HMI displays the way an operator does, with no instrumentation of the target system.

—Camera-based or screen capture observation
—No modification of the target software
—Adaptive to UI changes across software versions
—Works with any display technology or OS

Compliance & evidence

Evidence generated automatically

Audit-ready reports

Structured test evidence from every run across all systems.

Software update compliance

Evidence that updates don't introduce regressions across variants.

Audit trail

Timestamped, structured test documentation generated automatically for every release.

Operator procedure manuals

User manuals generated automatically from recorded workflows for each system variant.

How it works
