How many test cases are needed to achieve minimum test coverage based on given grading conditions?

To determine how many test cases are needed to achieve minimum test coverage based on given grading conditions, it's essential to understand the concept of test coverage and how it relates to the specific conditions being tested.

In this context, minimum test coverage refers to the least number of test cases required to adequately test all specified grading conditions. These grading conditions could involve various scenarios and outcomes that need to be covered, such as different score ranges, edge cases, or specific requirements outlined in the testing specifications.

Achieving the correct number of test cases relies on analyzing each grading condition and ensuring that all possible outcomes are tested. The calculation typically includes evaluating each condition to ensure that each possible scenario is represented in a test case.

Choosing 8 test cases indicates that this is the least number necessary to comprehensively satisfy all conditions presented. This choice reflects a balanced approach to coverage, ensuring that no significant condition is overlooked while not excessively duplicating efforts through redundant test cases.

Ultimately, the selection of 8 test cases is indicative of a careful consideration of test scenarios, leading to a strategic and efficient testing process that ensures all necessary conditions will be adequately validated.
