Not at all. It’s also about validating user experience, checking performance, ensuring compatibility on different devices/browsers, and confirming that the system behaves correctly under various conditions.
For manual testing — not necessarily. Understanding workflows and thinking analytically is key.
For automation testing — some scripting knowledge (like Python, Java, or JavaScript) is helpful, but you don’t need to be a full-stack developer.
Manual testing is when a person tests features step-by-step. Automation testing uses tools/scripts to test faster and in bulk. Manual testing is for exploratory and usability checks, while automation is for repetitive and large-scale testing.
Absolutely. As long as software exists — QA roles will exist. With the rise of automation, AI, and continuous delivery pipelines, skilled testers are more valuable than ever.
