How is Heisenbug handled?

Heisenbug is not documented in any standard way or with a special document. It is a term that denotes a type of bug whose behavior changes or disappears when attempting to investigate or debug it.

When working with a Heisenbug, it is important to record as much information as possible about the context in which it occurs:

• Exact reproduction steps (even those that seem insignificant).
• System state (load, memory, CPU).
• Application and system logs.
• Software version, environment (OS, browser).
• Time of the error occurrence.
• Test or environment configuration.

This information is usually added to the standard bug description in a bug tracking system (Jira, Azure DevOps, etc.), explicitly indicating instability or the inability to reproduce fully, and assigning a high priority for investigation.
