Short answer

How can I debug failed tests using my AI?

Your AI uses Mabl tools to fetch specific execution details and visual evidence. It pulls the exact failure reason and screenshots so you can identify the root cause in your chat window. You get a clear breakdown of what went wrong.

The outcomes.

Where your debugging data lands.

The AI organizes the information it pulls from Mabl into these specific outcomes.

TRIAGE

Failure summaries

The AI pulls the specific error message from the execution. You get a plain-text explanation of why the test stopped.

VISUAL

Screenshot analysis

The agent retrieves visual evidence from the failed run. You can see exactly what the UI looked like at the moment of failure.

HISTORY

Execution logs

The AI looks through previous runs to find patterns. This helps you see if a failure is a one-off or a recurring regression.

HUMAN

Manual fixes

The AI identifies the problem but doesn't touch your code. You still need to go into your IDE to apply the actual fix.

The workflow

What your AI does when a test fails.

The AI acts as a bridge between your test runner and your conversation.

  1. Locate the failure

    The agent scans your recent Mabl activity to find the specific run that didn't pass.

    mb.list_executions

  2. Fetch error details

    The AI pulls the specific failure reason and metadata for that exact test instance.

    mb.get_execution

  3. Analyze visual state

    The agent retrieves the screenshots captured during the failed step to show you the UI state.

    mb.get_execution

  4. Summarize root cause

    The AI combines the error text and the visual data to explain the problem to you.

    mb.get_execution

    Can the AI fix my Mabl tests automatically?

    No. The AI can only read the execution data and screenshots to tell you what happened. You have to perform the actual fix in Mabl.

  • 02

    Can the AI trigger a new test run?

    No. The current tools only allow the AI to list and get details from existing executions.

  • 03

    Does the AI see all my Mabl data?

    The AI only sees the data it needs to answer your specific question, such as execution logs and screenshots.

  • 04

    Can the AI delete failed executions?

    No. The AI has no capability to delete or modify any data within Mabl.

  • 05

    How does the AI get the screenshots?

    The AI uses the execution data provided by Mabl to retrieve the visual evidence associated with a failed step.
