Browser testing that follows the journey beyond the first screenshot.

whether Save saved anything.
/carbon-browser puts CARBON's investigation into a
reachable page or web application using an available local browser
controller. The agent can inspect, act, observe, and change its next
question based on the result.
The interesting
part happens after the click
Take an upload flow. Choose a file, watch the progress, interrupt it,
retry, and inspect the resulting record. Does the app show the right
file? Is there a duplicate? Does the error leave the form usable?
Source code can explain the implementation. Browser evidence shows
what the user encountered in the tested environment. A useful report
connects the two without pretending that reading a handler means the
interaction succeeded.
CARBON keeps page states and relevant evidence so a finding has a
location, a sequence, an expected result, and an observed result.
Surprising failures deserve another attempt from a known state.
Use an isolated session
/carbon-browser test the local upload flow with synthetic files; inspect progress, cancellation, retry, and reload
The default should not be your everyday browser session, with its
real accounts and open customer work. The command negotiates available
browser capability and respects gates around purchases, messages,
deletions, and other consequential actions.
If the necessary controller or access is missing, that is a blocker
to report, not a reason to describe imagined clicks.
The convenience is straightforward: investigate the interface in the
same coding conversation where the feature is being built. A browser
journey should not require a second project just to ask the first useful
question.
