what is V Model?

By -
The V-Model splits testing into two parts as Design and Execution. The model starts with overall business requirement.Once the requirement is ready then software,hardware,human resource requirement becomes the next step.Then the detailed design of software will be prepared based on the SRS..This design document will be used as a blue print for the later phases like coding and testing. Test design starts with the time when requirement document (SRS) is ready. Test design is done early while the test execution is done at the end.

After design phase, the construction(coding) will be followed based on the system design document and SRS. As the testing design is ready, the execution of testing will be conducted by the tester.There are different types of tests for each phases of this life cycle model.

In Execution, program units have to be tested independently before combining them into components. This is called Unit testing. With the individual units of system is tested then units are combined together as Component, then the component is tested is called Component testing. Then all the tested components are integrated to form a whole system and the integration between these components are tested in Integration Testing. When the whole system is ready it is tested according to the customer requirement.This is called system testing. Then the final product is tested by the customer and it can be accepted if all the requirement is met without any faults. This is called Acceptance testing.

Advantages:
  • as  test plans are prepared along wit the project plans, execution starts immediately once the code is ready
  • changes can be updated in any phase before execution
  • reducing last minute work
Disadvantages:
  • all the units should be ready at the time of component testing
  • all the components should be ready at the time integration testing
  • if the unit or component is not ready then other tested units & components have to wait for that units & components have to be done
  • waste of time to wait for other units or components

What is Prototype Model?

The goal of prototyping based development is to counter the first two limitations of the waterfall model. This prototype is developed based on the currently known requirements. Development of the prototype obviously undergoes design, coding and testing. But each of these phases is not done very formally or thoroughly. By using this prototype, the client can get an "actual feel" of the system. Advantages It could serve as the first system. Prototyping is an attractive idea for complicated and large systems for which there is no manual  process or existing system to help determining the requirements. The customer doesn’t need to wait long as in the Linear Model. Feedback from customers are received periodically and the changes don’t come as a last minute surprise. Users are actively involved in the development It provides a better system to users, as users have natural tendency to change their mind in specifying requirements and this method of developing systems s

State-based and Graph-based Testing: The Ultimate Beginner’s Guide State-based and Graph-based Testing: The Ultimate Beginner’s Guide Hey there! 👋 Today, we're talking about State-based testing and Graph-based testing , two techniques that help make sure software behaves just the way it's supposed to. And don’t worry—we’ll keep things simple with real-life examples to make it all crystal clear! Ready? Let’s get started! 🚦 What is State-based Testing? State-based testing is a technique where the software is tested by considering the various states of the system and how it transitions from one state to another based on different inputs or events. This technique is particularly useful when the software’s behavior depends on its current state. Imagine you’re driving a car. Your car’s state changes based on what you're doing, right? It could be in "Park," "Drive," "R
