Few Testing Methods for Software Testing :
1.Destructive Testing:
Ø The
destructive testing is about breaking the software application to assess their
quality. It is done intentionally to check the robustness of the software and
find out the point of failure.
Ø It
checks the unpredictable behaviour of the application. The most interesting
thing is that there is no need to understand the original requirements of a
software product.
Ø The
benefits of this testing is that it helps to understand predictable behaviour
when the software is put in unfavourable conditions.
Ø During
destructive testing, proper and improper software behaviour is checked. Also,
improper usage, improper input data and proper output data are checked.
Ø The
destructive testing can be used with other testing like Alpha/Beta Testing,
Regression Testing, Acceptance Testing, etc.
Ø There
are some conditions in destructive testing such as the software will not
process invalid input data and output data should always be correct
regardless of the type of input data is given.
2.Fault Injection Testing:
Ø It
is done by introducing a fault in the code for testing the robustness of the
application and its capabilities in the error handing.
Ø When
the fault is introduced directly into the code it is called compile – time
injection and when the fault is introduce through the software triggers to
cause specific scenarios in a running system it is called runtime injection.
Ø The
purpose is to ensure that the system is able to recover from the fault and
identifies the design weakness where even a single fault could lead to severe
error or systemic failure.
3.Endurance Testing:
Ø This
testing is also known as soak testing. It is done to check whether the
application can sustain the load for the long time or not. It is a type of
non-functional testing.
Ø The
system reaction parameter is measured by examining the system whether it can
sustain a huge load for a longer period of time.
Ø The
benefits of this testing is that it helps to find out the critical memory leaks
that may lead to the crash of an operating system.
Ø The
failure to close connections between the layers of the system may leads to stop
working of modules of the system. The failure to database connections may lead
to system crash.
4.Equivalence Partitioning
Testing:
Ø There
is time and budget constraints so it is not possible to do exhaustive testing
for each set of test data. The tester
needs to intelligently select test cases from the pool of data that covered all
the scenarios.
Ø In
this technique the input data is divided into different equivalence data
classes. The advantages of this testing is that it gives clear guidelines for
determining the test cases without comprising the effectiveness of the data.
