To answer this question, you need to understand the concept of Cyclomatic Complexity and its relationship with testing methods.
Cyclomatic Complexity is a software metric that measures the complexity of a program by counting the number of independent paths through the code. It helps in determining the number of test cases required to achieve a certain level of coverage.
The testing method that involves considering the internal structure, logic, and implementation details of the software is known as White box testing. White box testing is also referred to as structural testing or glass box testing.
Therefore, the correct answer is:
Option D) White box - This option is correct because Cyclomatic Complexity is a metric used in white box testing to measure the complexity of a program and determine the number of test cases required.
