Topic #: 2
What are the various activities performed in the planning phase of the Software Assurance Acquisition process? Each correct answer represents a complete solution. Choose all that apply.
Graybox testing is a combination of whitebox testing and blackbox testing. In graybox testing, the test engineer is equipped with the
knowledge of system and designs test cases or test data based on system knowledge. The security tester typically performs graybox testing
to find vulnerabilities in software and network system.
Answer C is incorrect. Whitebox testing is a testing technique in which an organization provides full knowledge about the infrastructure
to the testing team. The information, provided by the organization, often includes network diagrams, source codes, and IP addressing
information of the infrastructure to be tested.
Answer A is incorrect. Integration testing is a logical extension of unit testing. It is performed to identify the problems that occur when
two or more units are combined into a component. During integration testing, a developer combines two units that have already been tested
into a component, and tests the interface between the two units. Although integration testing can be performed in various ways, the
following three approaches are generally used:
The top-down approach
The bottom-up approach
The umbrella approach
Answer B is incorrect. Regression testing can be performed any time when a program needs to be modified either to add a feature or
to fix an error. It is a process of repeating Unit testing and Integration testing whenever existing tests need to be performed again along with
the new tests. Regression testing is performed to ensure that no existing errors reappear, and no new errors are introduced.
