You implemented the task, found an undocumented critical case during testing, and the release is in two days. What are your actions?

If a dangerous case is discovered two days before the release, it is important to quickly assess the risk and make a decision:

1. Inform the team and management about the identified problem, describe its impact and likelihood of occurrence.
2. Evaluate whether the bug can be quickly fixed and conduct minimal testing.
3. If the fix is possible without significant risk, apply the patch and perform regression testing.
4. If the fix is risky or time-consuming, consider postponing the release or releasing with a known limitation, accompanied by a relevant warning.

The main thing is not to ignore the problem and not to release a potentially dangerous product without informing interested parties.
