Answer / me a tester

Well Guys its a very common interview question :

Functional testing : •It is testing of application
functionality and examination of its compliance with the
software requirements specification (SRS).

Usability Testing: Lets learn this with an example

E.G If you go in a hotel where there are 5 rooms
Room 1 - Bed room
Room 2 - Kitchen
Room 3 - Bathroom
Room 4 - Noraml room
Room 5 - Servent room

If you are asked to go in kitchen what will you do .. you
open each room to check which one is the Kitchen.
if we need to make this task simpler what we need to do ?
we just put a lable in front of each room then what I need
to do just read the label and find where the kitchen is..
this is called usability testing .
In short the button that is label as resgistration form
opens the resgistration form.

Perforamance testing :

Well performance testing is a mixture of two things

Load Testing , Stess Testing.

Now what are they
Load Testing : E.g If 100 user hits on a same button on a
website at same time it is called load testing.

Stress Testing: E.G If 100 user hits on 6 different buttons
on same time is called sterss testing

of the application such as response time,throughput.
these performance testers test the performance of the
application by using some performance tools such as Load
runner,jmetre..

Functional testing – This type of testing ignores the internal parts and focus on the output is as per requirement or not. Black-box type testing geared to functional requirements of an application.
