What is software testing?
Definition:
Software testing is a process of comparison between Expected result and Actual result of the software, and to ensure that the software should be defect free. Through the testing testers can identify the errors, gaps or requirement missing elements of the system.
In IT industry software testing can be done either Manually or Automation Testing using available tools.
Testing is important to meet the customer
requirements. If software in the system is not tested properly before its
launch, then there is a chance to fail the software or possibility to force an error in the system and it also effective to loss the
Reputation, Money, Time and Life.
For Example:
Traffic signals are the way of solution to control vehicle movement and the traffic signals all are working on software. For the normal working of the traffic signals we need to do software testing of the traffic signal. Because if we do not test the software and launch without testing, then there is may chance to fail the proper working of software and traffic signals may not be working properly and the possibility of the accident may increase.
When we develop software we all make mistakes in the software. Software testing is necessary to find the defect in the software during the development.
To check the software there are Three major factors are Important as given below:
a) Correctness
b) Completeness
c) Quality
