Passive income: NO

Quality Assurance (QA) testing is generally not a passive income side hustle. Most QA testing requires active participation, such as manual testing, writing test cases, and reporting bugs. Automation can reduce manual effort, but setting up and maintaining automated tests requires ongoing work. Outsourcing is possible, but it involves managing a team, which is not passive. Most people do not reach a passive income level in QA testing; it remains active work. Some may believe automation leads to passive income, but it often requires significant initial setup and continuous updates. Passive income in QA testing is rare and typically only achieved by a few outliers who manage to create a highly efficient system or tool that others use.
