In which of the following testing methods is the test engineer equipped with the knowledge of
system and designs test cases or test data based on system knowledge?
A.
Integration testing
B.
Regression testing
C.
Whitebox testing
D.
Graybox testing
Explanation:
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 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.
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
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.
