What does the fuzzing method involve when testing a line?

The fuzzing method, when testing a line, involves not relying heavily on traditional measurement techniques or tools. Instead, it often refers to a method of increasing the confidence in assessments through a less precise approach that may include observing the behavior of the line rather than performing detailed measurements.

The other options focus on concrete methods of testing that involve direct physical interaction or measurements with instruments, which are more conventional and often viewed as more reliable. For example, using high voltage terminals or directly touching the line with a tool involves clear and definitive actions that follow standard testing protocols. Reading the line with a digital multimeter represents a precise and accepted practice for verifying electrical states. These methods provide tangible and verifiable results, differing significantly from the fuzzing method’s more abstract and less formal approach to testing.
