FAQ: August 2026 Webinar Q&A

By David Frank

Question

Answer

Can Sandbox capture screenshots during testing?

Yes. Screenshots can be captured through ADB or OCR, depending on the environment. Capture commands can also be included when building a test case, allowing screenshots to be collected at specific points during execution. Sandbox itself does not store the artifacts during the interactive session, but the capture commands can be prepared for the automated test run.

Question

Answer

Can the entire test execution be recorded as a video?

No. Full video recording is not currently available due to the amount of data it would generate. Instead, teams can capture as many screenshots and text outputs as needed. Screenshots can also be captured automatically when a test step fails, providing evidence of the terminal state at the point of failure.

Question

Answer

Can an already saved test case be edited in Sandbox?

Not yet. Editing an existing saved test case directly in Sandbox is a planned future capability. The intention is to allow users to load an existing test case, modify it, and save the changes as a new version, supporting greater traceability through test case versioning.

Question

Answer

Does the ADB extension rely on OCR, or can it use resource IDs?

ADB and OCR are separate methods. ADB connects directly to the terminal, typically over USB, and receives its own data stream rather than relying on camera-based OCR. With ADB, interactions can also target resource IDs instead of only recognized text.

Question

Answer

Can cards from an EMV L3 test tool be selected directly in Sandbox?

Not currently. Integrating test cards from third-party EMV L3 tools directly into the selectable card list is something PaytestLab is exploring. The goal would be to make those test cards available for selection directly within the testing environment, but this functionality is not yet implemented.

Question

Answer

Can magstripe cards be used in Sandbox?

Yes. PaytestHub includes a magstripe card library with several predefined cards, and users can also add and label their own. Test cases can reference a card by its name or label, allowing the appropriate magstripe card to be selected and swiped. This functionality can be used from Sandbox as well as when creating a standard test case.

Question

Answer

Can Sandbox extract a transaction reference for use in another test step?

Yes, provided the transaction reference is accessible within the environment. For example, it can be extracted from a terminal screen using ADB or OCR, or from a returned payload in an integrated setup. The extracted reference can then be stored as a variable and reused in a subsequent test step.
