What is an Edge Case?
An Edge Case is a scenario that occurs only under extreme or unlikely conditions, often at the boundaries of the system’s capabilities. While edge cases may be rare, they can reveal vulnerabilities or limitations in the design, making it essential to consider them during the development process.
Designers and developers must decide how to handle edge cases, balancing the need for robustness with the cost and complexity of addressing them. Ignoring edge cases can lead to negative user experiences or system failures, particularly for users with specific needs or in unique situations. Testing for edge cases ensures that the product is resilient and can accommodate a wide range of user interactions.
