​
Helper throws because no client is configured

Cause: The flow called a client-dependent helper before the runner configured the testkit client. Check:
  • the runner calls configureTestkitClient(...) before flow execution
  • tests call resetTestkitClient() between cases

​
saveBaselineScreenshot() throws

Cause: The configured client was created without saveSnapshot. Check:
  • the runtime passed snapshot support into createTestkitClient(...)

​
QR code helper returns undefined

Check:
  • the selected element actually contains a QR code
  • the screenshot is stable and large enough to decode reliably

​
Update a baseline screenshot programmatically

If the QA Wolf editor doesn’t let you promote a new screenshot as the updated baseline, you can do it in flow code instead. Add saveBaselineScreenshot to the flow temporarily, run it once to save the new baseline, then remove it.
The name must exactly match the name used in the corresponding toHaveScreenshot call. Remove this line once the baseline has been updated — it is not meant to run in normal test execution.
