WHY TESTING IS NECESSARY BEFORE DEPLOYMENT


Deploying a software without testing is equal to riding a bicycle without brakes






Example :
If a person is riding a bicycle with maximum speed suddenly he saw a big tree in front of him then he applied the brakes but brakes are not working then what’s the condition of the person


In the same way a company developed a software according to client’s requirement in a company’s environment I do not know whether software is working as client’s need but I know software works.
Now company deployed a software to the client after reaching the software to the client. Now Client started using it in hospital. but because of change in environment my software works in different way .


Now software should work like this :

Software should stop working for every 20 seconds and after 10 seconds again software should start working but because of change of some code and change in the environment software is not getting stopped for every 20 seconds its working continuously

Software is working like this :

If the patient is sent to a automatic machine for a treatment to cure some disease at that time machine is using the software which our company was developed and it was the first time the doctor is using our software in his hospital then what’s the situation of the person who went inside the machine is ?

Example :
So deploying software without doing testing some time causes to death. And the bicycle incident shows without testing starting the work some time gives us a bad result so start testing when something is going to do
Developing software may takes only some years but testing that developed software can take impractical amount of time
