Software is a key
success factor for many businesses across departments like Accounting and Finance,
HR, R&D, Sales, and Production. However simply developing the software is
not adequate. It has to be thoroughly tested for all performance metrics. Not using
testing to run your development project is hardly a peril you can afford to
take in today’s times of cut-throat competition. System testing and integration
testing offer two very good avenues to plug in any issues and avoid mishaps
post release. Get to know these different forms of testing and what benefits do
these provide -
Key Types of Testing
1. System Testing
System testing is
the mechanism used in the testing of a completely integrated system to verify and
ensure it meets the defined means or specified requirements. What this means is,
during system testing the entire system will be tested as a whole to make sure
it complies with the desired outcomes.
2. Integration Testing
involves the combination individual software modules to test them as a group. However,
before integration testing, your software professionals need to conduct unit
testing to check the credibility of every module.
Main Differences between System Testing and Integration
A] What do they focus on?
System Testing – It will always
concentrate on functional and non-functional testing. This includes testing of security,
load, recovery, performance and stress.
Integration Testing – When
it comes to integration testing, the main focus is functional testing. That is, how
two modules should be combined and tested in the form of a group.
B] Where do they start?
System Testing – It is supposed
to start from requirement specifications. This is because it is meant to check whether
the system works properly in accordance with the requirements set.
Integration Testing – On the
other hand, integration testing begins with the interface specifications. This way,
it is possible for software engineers to determine whether or not the different
software modules are capable of integrating efficiently.
C] What do the professionals pay attention to?
System Testing – The persons
conducting system testing have to focus on the functionality of the system when
it comes to system testing.
Integration Testing – In case
of integration testing, the testers need to pay attention to how well the
modules integrate with each other.
D] What happens first?
System Testing – Before conducting
system testing, it is essential for the testers to perform integrated testing.
Integration Testing – Prior
to integrated testing, unit testing is compulsory, only then can the testers proceed
to test the integration capacity of individual software modules.
E] Visibility testing
System Testing – For system
testing, there is no visibility testing conducted with regards to the code.
Integration Testing – It involves
the testing of the visibility of the modules integration structure.
F] Level of testing
System Testing – It is considered
to be high-level testing because it takes place after the integration testing process
Integration Testing – This
testing is a low-level testing because it is involved in the initial stages of
You can easily optimize
the entire software development lifecycle by making a judicious and budget
friendly decision based on these two critical forms of testing.
