what is Agile(scrum) & XP Methodology

By -
Agile & XP(Extreme Programming)  Methodology becomes the most popular testing method among Testing Industry. The main reason is this methodology emphasizes the involvement of the entire team and their interactions with each other, to produce a workable software that can satisfy a given set of expected features.As a result of such interactions, all ideas are exchanged among team members. and also the customer becomes the part of the project team so as to clarify any doubts/questions according to requirements.

In these models, the project team work step by step in bringing the project to completion in a phased manner.Software is delivered as small releases, with features being introduced in increments. As the changes are introduced incrementally, responding to the changes becomes very easy.

A typical XP & Agile project day starts with a meeting called stand up meeting. At the start of each day, the team meets to plan of action for the day. And the team brings up any clarifications or concerns and these are discussed and resolved. The entire team gets a consistent view of what each team member is working on. This meeting enable quick reactions to changes.

Even though the roles of testers and developers are different, in Agile & XP methodology there is no hard boundary between their roles. People cross boundaries and perform different roles in these models.

Advantages:

  • End Results with a Quality software
  • Better and immediate communication within project team including customer
  • Save of time and effort as the changes can be suggested at the time before going to depth
Disadvantages:

  • If the Customer representative is not clear with the requirement, then the whole team will go with the wrong path

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
