Q. What are dynamic testing tools? Explain the functions that they must support.
Ans. Dynamic testing tools:
1: coverage analyzers (execution verifiers): A coverage analyzer is the most common and important tool for testing. It is often relatively simple. One of the common strategies for testing involves declaring the minimum level of coverage, ordinarily expressed as a percentage of the elemental segments that are exercised in aggregate during the testing process.
2: output comparators: these are used in dynamic testing-both single-module and multiple- module (system level) varieties to check that predicted and actual outputs are equivalent. This is also done during regression testing.
