What Is The Difference Between Coverage-Based
Testing And Usage-Based Statistical Testing
Perspective
Usage-based statistical testing considers the
objects of testing from a users side and pays
the main attention to the usage scenarios,
sequences, templates. At the same time
coverage-based testing considers the objects of
testing from a developers side and pays the main
attention to covering functional or execution
units.
Objects
Although the objects tested may overlap,
coverage-based testing is commonly used to test
and cover not very big objects and usage-based
statistical testing is commonly more appropriate
for big software systems.

What Is The Difference Between Coverage-Based
Testing And Usage-Based Statistical Testing
Timescale
For big software systems, coverage-based testing
is often used in early sub-stages of software
testing. At the same time usage-based testing is
usually used in late sub-stages of testing, such
as system and acceptance testing.
Independent Verification Validation
Although both coverage-based and usage-based
testing can be used for both verification and
validation test, usage-based statistical testing
is more likely to be used for validation test
because of their interrelation to clients and
users.

Software Bug Identification
In usage-based statistical testing, software
bugs that are more likely to be detected by users
are also more likely to be monitored in testing,
which may lead to corresponding bugs being
identified and eliminated for reliability
betterment. In coverage-based testing, bugs are
more closely related to objects under test,
leading to effectual software bug removal.

What Is The Difference Between Coverage-Based
Testing And Usage-Based Statistical Testing
Testing environment
Usage-based statistical testing uses testing
environment similar to that for in-field
operation at client installations. At the same
time coverage-based testing uses environment
specifically set up for testing.
Techniques
Different techniques may be used to construct
models and create test cases to conduct
systematic coverage-based testing. When these
models are augmented with usage information,
normally as the probabilities associated with
checklist items, partitions and states they can
be used as models for usage-based statistical
testing as well.

Testing And Usage-Based Statistical Testing
Software Tester
Dedicated professional software testers normally
conduct usage-based statistical testing and
coverage-based testing may be conducted by either
professional testers or by developers themselves.
Client and User Roles
Usage-based statistical testing models are
created with comprehensive client and user input.
At the same time coverage-based testing models
are often created without active client or user
input.

Testing And Usage-Based Statistical Testing
Stopping aspect
Usage-based statistical testing uses product
reliability purposes as the stop criteria while
coverage-based testing uses coverage purposes as
the stop criteria.
