Why is it beneficial to write test cases based on experience and intuition?

Writing test cases based on experience and intuition is beneficial because it allows testers to draw from their firsthand knowledge of similar systems, past issues, and user behavior to identify potential problems that may not be easily captured by formal testing techniques alone. This practical insight can enhance the effectiveness of testing by providing a more comprehensive view of the application under test.

Experience often reveals common pitfalls or tricky functionalities that may be overlooked in a formal test scenario, especially in complex or dynamic environments. By supplementing formal testing techniques with insights gained from experience and intuition, testers can create a more robust set of test cases that covers a broader range of scenarios, including edge cases and usability concerns. This combination not only improves the likelihood of finding defects but also leads to a more user-centric perspective on testing, as the insights from real-world experience can inform better test design.
