What type of testing is based on the tester's knowledge, experience, and intuition?

Experience-based testing is grounded in the tester's knowledge, experience, and intuition. This approach leverages the tester's understanding of the application under test, combined with their insights into potential weaknesses or challenging areas that may not be easily covered by formal test cases. It relies heavily on the tester's ability to identify risks and to formulate test scenarios based on their past experiences, domain knowledge, and the context of the project.

This type of testing is particularly valuable in environments where agile methodologies are employed, as it allows for rapid exploration of functionalities without the constraints of predefined test scripts. It encourages testers to think creatively and to utilize their judgment to discover defects that might otherwise be overlooked in structured testing processes. This adaptability is a key strength in iterative development cycles.

In contrast, automated testing relies on predefined scripts and does not inherently incorporate the tester's intuition or experience. Ad-hoc testing, while also informal like experience-based testing, does not systematically use the tester's prior knowledge to guide the test process. Scripted testing is based on detailed specifications and requirements, which again contrasts with the exploratory and intuitive nature of experience-based testing. Thus, the focus on utilizing the tester's own insights and background as the core of the testing approach makes experience-based testing the correct answer
