Aircraft went into service with all passenger O2 (Oxygen) test stop buttons deployed. I worked on Passenger Oxygen Masks Inspect Zone 231 and Zone 232. I inspected masks; cleaned them; and closed oxygen panels. Test stop buttons were in stowed position at the end of my shift.
B737 Technician reported that aircraft was released for service with passenger oxygen test stop buttons deployed.
