What is overnight manual software testing?

Overnight manual software testing refers to the process where testers manually execute test cases and validate software functionalities during the night shift, typically outside regular business hours. This approach is often used to maximize productivity by ensuring testing progresses around the clock, especially for projects with tight deadlines or global teams. Testers in this role identify bugs, verify fixes, and ensure software quality without relying on automated tools, making their observations and documentation crucial. Working overnight may also involve collaborating with teams in different time zones and ensuring that any critical issues are communicated before the start of the next business day.
