Structural
Software Testing
Structural
testing is a type of software testing that
uses the internal design of the software for testing or in other words the software
testing which is performed by the team which knows the development phase of the
software, is known as structural testing.

Structural
testing is related to the internal design and implementation of the software
i.e. it involves the development team members in the testing team. It tests
different aspects of the software according to its types. Structural testing is
just the opposite of behavioral testing.
Types of Structural Testing
There
are 4 types of Structural Testing:
Types
of Structural Testing
Control Flow Testing:
Control
flow testing is a type of structural testing that uses the programs’s control
flow as a model. The entire code, design and structure of the software have to
be known for this type of testing. Often this type of testing is used by the
developers to test their own code and implementation. This method is used to
test the logic of the code so that required result can be obtained.
Data Flow Testing:
It
uses the control flow graph to explore the unreasonable things that can happen
to data. The detection of data flow anomalies are based on the associations
between values and variables. Without being initialized usage of variables.
Initialized variables are not used once.
Slice Based Testing:
It
was originally proposed by Weiser and Gallagher for the software maintenance.
It is useful for software debugging, software maintenance, program
understanding and quantification of functional cohesion. It divides the program
into different slices and tests that slice which can majorly affect the entire
software.
Mutation
Testing:
Mutation
Testing is a type of Software Testing that is performed to design new software
tests and also evaluate the quality of already existing software tests.
Mutation testing is related to modification a program in small ways. It focuses
to help the tester develop effective tests or locate weaknesses in the test
data used for the program.
Advantages
of Structural Testing
·
It provides thorough testing of the software.
·
It helps in finding out defects at an early stage.
·
It helps in elimination of dead code.
·
It is not time consuming as it is mostly automated.
Disadvantages of Structural
Testing
·
It requires knowledge of the code to perform test.
·
It requires training in the tool used for testing.
·
Sometimes it is expensive.
