The application unexpectedly crashed during testing. What are your actions?

If the application unexpectedly crashes during testing, my actions would be:

1. Gather information: check application logs, system logs, error messages.
2. Reproduce the error: try to repeat the scenario to understand the conditions of the crash.
3. Analyze the cause: determine whether the problem is related to code, environment, resources, or external services.
4. Document: record reproduction steps, logs, and analysis results.
5. Report to the team: pass the information to developers or support responsible.
6. Propose solutions: if possible, suggest workarounds or fixes.

This approach helps quickly localize and resolve the issue.
