What is operational testing in software testing?

Operational testing alludes to the assessment of a product application preceding the creation stage.
Operational testing guarantees framework and part consistence in the application's standard working condition
(SOE). 

Operational testing is applied in a predetermined domain during different programming advancement life cycle
(SDLC) stages for the assessment of programming framework usefulness. 

Operational Acceptance Testing guarantees framework and segment consistence in the application's standard
working condition (SOE). 

Types of Operational Testing

Installation Testing

Load & Performance Test Operation

Backup and Restore Testing

Security Testing 

Code Analysis 

Failover Testing 

Recovery Testing

End-to-End Test Environment Operational Testing

Operational Documentation Review 

Why Operational Testing ?

During OAT programming setups and operational help, segments meet up 

It tests the execution of useful or basic changes to programming or administration in a practical or non-useful
condition 

This testing decides if an application can be sent on a system as indicated by IT Infrastructure Library (ITIL)
norms 

It tells whether a product will work the manner in which it is intended to without disturbing the business
procedure 

OAT focuses for the most part on these parts of programming item 

Versatility 

Recovering ability

Manageability and supportability

Integrity

Conclusion:

In Software Testing, Operational Testing ensures that the framework and part's consistency in the application's
standard working condition (SOE).
