What is a set of input values that cover the boundary values for an e-commerce system selling cooking supplies?

In the context of boundary value analysis, which is a testing technique that focuses on the values at the edges of input ranges, the correct answer includes values that specifically target the boundaries related to input limits for the e-commerce system selling cooking supplies.

Option C features the values 0.4, 0.5, 25.0, and 25.1. This set effectively captures important edge cases:

• Values like 0.4 are just below a lower boundary, while 0.5 represents that lower boundary, allowing for the examination of both inclusion and exclusion at that point.
• Similarly, 25.0 is the upper boundary, and 25.1 is just above it. This allows testers to check if the system correctly allows or denies input at these critical junctures.

By including boundary values, this selection helps ensure that the system behaves correctly at the very limits of acceptable input, which is crucial for verifying that the application can handle edge cases without errors or unexpected behaviors. Such thorough testing at boundary conditions is essential in e-commerce systems to prevent issues that could lead to financial discrepancies or poor user experiences.
