SDLC MCQ

Software Development Life Cycle:

The Software Development Life Cycle is a process used in the software industry to produce and design high-quality software. The SDLC follows certain stages of designing, developing, testing software before launching it.

A typical SDLC life cycle is as follows:
There are various types of SDLC modes. Some of the popular SDLC models are as follows:


Software Prototyping

  • The process in which developers create a model of the actual software.
  • The intention behind creating this model is to get the actual requirements more deeply from the user.
  • Prototyping helps a lot in getting feedback from the customer.

 

Process of software prototyping

  1. Initial requirements identification
  2. Prototype Development
  3. Review
  4. Revise
     

Types of prototyping

  1. Rapid Prototyping/Throwaway: In this type, we build a prototype with very little effort to get the requirement from the user after getting the requirements, we throw away this prototype and start building the actual software.
  2. Evolutionary Prototyping: The prototype on the top of which we can build the whole actual system.
     

Testing in Software Engineering 

  • At different stages of software development, we need to test what we develop.
  • When we develop a unit, we test it when we integrate it with other units.
  • Also, it needs to be tested before giving the software to the customer.
  • In some testing types, we directly deal with the code, which is known as white box testing.
  • In some other cases, we do not have to look at the code and it is known as black-box testing.
  • A mixture of these two is known as gray box testing.

 

Unit Testing

  • Testing a single unit of the software is known as unit testing.
  • In this testing, we will test an isolated unit of the software, which contains lots of the units.

 

Integration Testing

  • Here, the testing of a few units of the software is done separately. Now, after testing, those units are integrated.
  • After integrating those units, it is again tested.
  • This is known as integration testing.

 

Regression Testing

  • Here, a new module is made and it is added to the software.
  • Whenever a new module is added to the software, it is tested to check whether the software is working fine with the change.
  • This is known as regression testing.

 

System Testing

  • The complete software is ready and working as a system.
  • In this testing, the focus is the entire software. The testing is done based on Evolutionary are input and output.
  • Software compatibility is tested on different kinds of OS.
  • Testing the software comes under the black box testing category.

 

Stress Testing

  • The software is tested under unfavorable conditions.
  • In this testing, the software is pushed to its maximum limit to check whether any failure occurs under some unfavorable conditions.
