Live Recorder for Test

Diagnose and fix serious software defects before they cause havoc on customer site with software flight recording technology

Record & replay program execution of your test run

Is your engineering team hitting intermittent failing tests which they can't reproduce and are left undiagnosed?

  • Catch sporadic failures exposed by your test suites which current debugging techniques and systems are unable to handle.
  • Record, rewind and replay your Linux C/C++ code to see the value of any memory location (and any register) at any moment in your program’s execution history.
  • Capture all non-deterministic data and reliably recreate your application’s entire memory and register state on demand at any point in its execution with minimal overhead.

What Live Recorder for Test can do for you

A data-driven approach to software failure diagnostic to reduce uncertainty and costly delays in your release schedule.

Clear your growing backlog of undiagnosed failing tests
Realise the full potential of your investment in Continuous Integration, turn your tests green and unblock your development pipeline.
Track down impossible defects
Capture the most challenging software defects - even the sporadic non-deterministic failures no-one can get to the bottom of.

Safeguard your customer relationships
Mitigate risks of outages, security breaches and memory leaks making their way into production and impacting your client relationships and bottom-line.

Chosen by world-leading organizations to deliver the highest quality software

How Live Recorder for Test works

Enhance your test suite to capture hard-to-reproduce bugs. Use Undo's record, rewind and replay technology to catch failures 'in the act' (making them 100% reproducible), and analyze the recording using Undo's reverse-debugging functionality.

Live Recorder for Automated Test seamless integration

Seamless integration

Run your program under the standalone Live Recorder executable or embed Live Recorder in your test suite. Replay is enabled by Live Recorder's reverse-debugging functionality UndoDB. No matter your set-up, we help you integrate our tools.

We are extremely excited about the potential to simplify and improve our fuzz testing infrastructure with Live Recorder, allowing us to significantly reduce the effort to find and fix complex defects very early in the development cycle.
Alexander Boehm
Test Architect, SAP

We started using Undo's reverse-debugging functionality when we were stuck on a memory corruption issue for over a week. Using Undo's software, we were almost immediately able to find the cause by setting a data break point on the corrupted data’s memory location, and running the process backwards in time until it hit the exact piece of code corrupting it. Saved us weeks of effort.
