What is Functional Testing?? Verifying the functionality of each and every component thoroughly or vigorously in an application against the requirement is called functional testing. Example : Requirement given by the customer for banking application  Login       1.1)Username: Username should be a 5 digit account number.  1.2)Password: Password should be a minimum of 6 and a maximum of 12 characters.           2. Amount transfer : 2.1)To a/c no: It should be 12 digits a/c number. 2.2)Amount: It should accept a minimum of 200 and a maximum of 50,000.                       2.3)Bank Name: It should be a valid bank name.

Software Testing   : Testing the application for finding defects and also to make sure that the software is not deviating from the requirement given by end user is called as Software testing. Different Testing Types is illustrated in the image below: White box testing : In white-box testing internal structure, design, coding of the application/software is tested. It is also called as open box testing, Transparent testing, Glass box testing, Transparent testing. Example :  Class A{ public static void main(String []args){ int a,b,c,d; a=10; b=20; c=a+b; System.out.println(c); } } In the above example, variable d is declared but not used. To perform white box testing, we should have good programming knowledge and hence most of the time it is done by developers. Black Box Testing : In black-box testing, we test the functionality of the application moreover as an end-user and hence we don't require programming knowledge. Grey Box Testing : Grey box testing is performed with limited i

In Derived Model, We derived the feature from one model to another and other features are added of our own. Example :   The spiral model is derived from the Water Fall Model. V - Model is also derived from Water Fall Model. Water Fall model is Known as Mother of all Models.  Also Read : What is Water Fall Model in SDLC?
