1. What is SDLC?

Answer: SDLC, Software Development Life Cycle is a process used by software industry to design, develop and test high quality software that meets or exceeds customer expectations.

2. What are The different models of SDLC?

  • Waterfall Model

  • Agile Model

  • Prototyping Model

  • Iterative Model

  • Spiral Model

  • V-Model

  • Incremental Model


3. What are the different types  of software requirements?

  • Business Requirements (BR): High level

  • Market Requirements (MR): high level drilling down into BR

  • Functional Requirements (FR) – Functionality of the product

  • Non-Functional Requirements (NFR)- Reliability, Scalability, Security, Integration, etc.

  • UI Requirements (UIR):


Market Requirements (MR) and  UI Requirements (UIR) are not included in traditional software requirements. 

4. Why do software have bugs?

  • SDLC involves humans at all levels which make software prone to human errors and also technical errors.

  • BA can make errors while gathering and documenting requirements

  • Developers can have programming errors.

  • Different parts of software may not communicate with each other

  • Complexity of software

  • Time limit

  • Multi Tier implementation.


5. What can happen if software is not tested?

  • Monetary loss

  • Time

  • Bad reputation

  • Law Suits

  • Injury/death

What is unit testing

https://www.youtube.com/watch?v=h9RvPN3kiHk&feature=youtu.be   Testing of individual software components or units or modules. Typically unit testing is done by the programmer and not by testers. Unit is smallest and complete set of code which accepts input, processes and gives output The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as you expect.

Regression Testing

https://www.youtube.com/watch?v=qaANTCZt20g What is Regression testing? It is a type of software testing that verifies that software performs correctly after the change or defect fix. Changes may include software enhancements, patches, hardware, networking, data structure, configuration changes, etc. In other words purpose of regression testing is to identify that  new defects are not introduced in the system after the change. 2) At what levels regression testing should be done? At all levels mainly Unit Testing, Integration testing and System Testing: Focus on testing is different at different levels. 3) What are the types of Regression testing techniques? Corrective Regression Testing: Progressive Regression Testing: Retest-All Strategy:. Selective Strategy: (dependencies between a test case and the program entities it covers) 4) What should be the frequency of regression testing? Ideally Regression testing should be done after bug fix and after any change to the syste
