Agile Methodology in Software Testing

Types of Requirements

We are now clear with the definition, so let's now move to the different types of requirements of Agile Methodology in Software Testing.

There are mainly three types of requirements of Agile Methodology, which are as follows.

1. Business Requirement: This is a crucial part of any Agile project. This tells why we are building the product and what benefits we are getting from the product. This condition is taken care from both client and the business team.
    
2. User Requirement: This part informs the benefits that users are going to receive after the development of the product. This also gives the task list that a user can perform using the software.
    
3. Functional Requirement: This part tells the features that must be present in the product after the deployment. The system engineer uses this requirement to analyse the tasks that need s to be done in the software/product.

Methods in Agile

There are many methods present in the Agile development process. We will discuss each of them one by one. 

Scrum

Scrum is a method that says to focus on task management within a team environment. Scrum believes in separating members into a short team structure so that development can be done on different parts of the product at a time. 

The Scrum has mainly three roles that are mentioned below.

• Scrum Master: The Scrum master gives the tasks to each team member. Along with this, the scrum master helps the members overcome the issues in the process. He also organises the meetings.
   
• Product Owner: The main task of the product owner is to check the backlogs and prioritize the tasks in the stack. He is also responsible for the delivery of tasks along with all features in each iteration.
   
• Scrum Team: The Scrum team performs their tasks and ensures that they are done on time with all the required features.

eXtreme Programming (XP)

The XP method works perfectly when the client is unsure about the features that must be present in the product. This method also works well when the owner constantly changes the demands. 

The steps to perform the XP are described in the below image.

The first step is the Project Requirement. The term Stories is used to describe the gathering of the business requirements. In this type of project, the update cycle is less known as iteration. It can be a span of 14 days time period.

The XP is further divided into 6 more phases. Let us have a look at them also.

• Planning
• Analysis
• Design
• Execution
• Wrapping
• Closure

Crystal

Crystal is based on the chartering process. It has three basic concepts that need to keep in mind while using the Crystal technique.

• Chartering: There are many steps that are involved in the phases. The steps include the developing team, a team that will perform the PFA (Preliminary Feasibility Analysis). Along with these, an initial plan and fine-tuning of the development method is needed.
   
• Cyclic Delivery: There must be two or more delivery cycles, including the team updates and rechecking the release plan. The implementation should be checked through the program test integrate iterations. The product must be reviewed before deployment.
   
• Wrap Up: This is the step where the product goes to the deployment process, and the users give feedback and review post-deployment.

Karban

The word Karban originated from a Japanese word whose meaning is a card that has all information. Similarly, the product's details should be noted after each stage completion. This method is mainly adopted in the agile concepts of software testing.

The main focus of Karban is to manage the work within the time period and without overloading the workers.

LSD

The full form of LSD is Lean Software Development. It follows a simple rule or principle that says, "Just in time production". The main motive for using this is to increase development speed and reduce cost.

The steps to perform the LSD are as follows.

• Eliminating Waste
• Amplifying learning
• Defer commitment (deciding as late as possible)
• Early delivery
• Empowering the team
• Building Integrity
• Optimize the whole

FDD

FDD means Feature Driven Development that involves the features of design and building. The FDD is different from other Agile methods as it has a feature to develop the product in short and specific phases separately.

The FDD has many features, such as design inspection, code inspection and design. The products in FDD are completed keeping the below things in mind.

• Domain object Modeling
• Feature development
• Class/ Component Ownership
• Feature Teams
• Inspections
• Configuration Management
• Regular Builds
• Visibility of progress and results

Pros of Agile Methodology

The advantages of Agile Methodology are as follows

• The delivery of software is unremitting in the Agile methodology
   
• The client can look at the work done by the developer and check whether the product has all the features that meet their expectation
   
• The product owner can also ask to change or update any features at a later stage
   
• The communication between the client and DevOps should not break in the Agile methodology as that features and other details may change daily
   
• The client will be satisfied as the dev team deliver the features with details after each cycle

Cons of Agile Methodology

The disadvantages of Agile Methodology are as follows:

• The documentation is very less in the Agile methodology
   
• The idea of actual effort can not be counted at the initial stage of the project
   
• Many times the features are not clear, which leads to zero prediction of the expected result
   
• The project may face an unknown bug that can lead to a major risk in the development

Frequently Asked Questions

Define Agile Methodology in Software Testing.

Agile Methodology is a process that is followed by the software development team. This process includes the iteration of development, testing and fixing the issues in the whole development cycle.

What are the different types of requirements in Agile?

The main three requirements in Agile development are Business, User, and Functional requirements.

Name the methods present in the Agile.

There are mainly six types of methodologies in Agile, which are Scrum, XP, Crystal, Karban, LSD, and FDD.
