* Self-teaching and on-the-job experience: Many game testers gain their skills through independent learning (using online resources, tutorials, etc.) and then entering the field as a junior tester. This route has no set timeframe.
* Associate's or Bachelor's degrees in related fields: A degree in computer science, software engineering, or a related field can provide a strong foundation for game testing, though it's not a direct path. These degrees typically take 2-4 years.
Therefore, there's no single answer to your question. If you're thinking of pursuing a related degree, it'll take 2-4 years. If you're looking to learn through experience, the timeframe is much more variable and depends on your learning pace and job opportunities.
