Agile Testing Methodology for Software Development
Agile Testing Methodology for Software Development
Agile Testing is a software testing practise that follows the principles ofagile software development.Collaboration between the customer of the projectand the project team plays a key role. Collaboration in general plays asignificant role when it comes to agile testing and helps to align thedevelopment of the project with the needs of its stakeholders.Advantages of Agile Testing in Agile Software Development: * Agile Testing saves time and money. As we all know, in the business world, time is money so that’s always a plus. * Less documentation to fill out and write up which also saves you time, money and effort. * Regular feedback from the stakeholders and end-users of the project which means that the project can be completed to suit the end-user in the best way possible. * Daily agile meetings held as part of the method help to determine issues and be prepared for them well in advance. Testing is not a phase of the agile method. The phases will be explained laterone. Testing is continuous throughout the project and ensure continuousprogress. It helps the project to move along its path. Continuous feedback isgenerated so that the project can complete its goals to the specificrequirements of the project user to its highest potential.With the agile methodology everyone tests, which means teams, developers andother stakeholders whereas in the more traditional methodology only the teamtests.In agile testing continuous feedback in each iteration allows for a shortenedfeedback response time which in turn, means that resolving an issue that hasarisen will cost less and take up less time. Any defects are seen to in eachiteration which allows for a consistently clean code.Instead of long documentation, agile testers focus more on the test as a wholerather than incidental details by using reusable checklists. Normally, withmore traditional methods, testing is carried out after implementation whileagile testing is carried out alongside implementation.
The Agile Software Development Team Structure
The agile methodology is heavily dependent on collaboration. Thus, it’simportant that you know the titles and roles of everyone involved in an agilesoftware development team structure.While the internal structure of an agile team may vary depending on whatspecific methodology you should use generally you can expect to have at leastthe roles specified below: * Team lead * Team members (or developers) * Product owner * TestersThe general responsibilities allowed for each role are self-explanatory.However, the specific way in which teams are assigned these responsibilitiescan largely differ. To clarify, there are 5 different types of agile teams.
Building an Agile Software Development Team
When you think about an agile software development team you might imagine agroup of professionals that function like a well-oiled machine with 150%efficiency and first-rate delivery speeds.Although that can be an ambitious goal for your development team, building anagile software development team demands intentional and perpetual effort.There is no one perfect solution or secret to building a highly-effectiveagile team, but here are some tips that can help you put together a solidteam.
Agile Software Development Philosophy and Methodology
When Alaistair Cockburn – one of the signatories of Agile Manifesto – rejectedthe very premise of “people as resources”, it helped set the cornerstone ofagile software development philosophy and methodology: * Treating complex systems, not people, as non-linear and non-deterministic * Adaptive methods instead of predictive * Reducing the “leap-of-faith” * Just the “right amount” of documentationAs another forefather of Agile Manifesto Martin Fowler writes, the agilemethodology developed as a reaction to engineering methodologies that he deems“bureaucratic”.According to him, planning out big chunks of software process in amazingdetail is all good – until change kicks in.That’s where engineering methods start resisting and fail while agile“welcomes change”, even thrives on it!Being people-oriented instead of process-oriented is another of agile’sphilosophical views. “Agile methods assert that no process will ever make upthe skill of the development team, so the role of a process is to support thedevelopment team in their work.”, writes Fowler.An example of Agile process’ sprint workflowIn describing a difference between predictive vs adaptive notions, heunderlines the separation of design and construction (the former is difficultto predict and needs costly and creative individuals and latter moreconvenient to predict).And while Fowler argues that predictability isn’t impossible, he’s certainlyaware of requirements unpredictability and the way to control them is through– iterations.Since agile software development is method tailoring, it’s distinguishingcharacteristic if situation-appropriateness.Time frames known as iterations involve teams working on all functions, at theend of which progress is reviewed (with the customer). After this, ROI is re-evaluated and optimized.Scrum, one of the agile process workflows, has some of the shortest iterationslasting only two weeks. This means that teams are in the constant process ofplans adaptation. For the betterment of this workflow, stories (descriptionsthat define requirements) are added to iterations.In close relation to agile software development methods are softwaredevelopment life cycles: practices such as pragmatic programming or workflowssuch as the aforementioned Scrum or Kanban).Other practices include: * Cross-functional teams * Behavior-driven development * Continuous integration * Iterative and incremental development * Pair programming * Planning poker * Refactoring * Story-driven modeling * Timeboxing * User story etc.
Collaboration in Agile software development
The people who are developing your project cover all critical areas ofexpertise. They will cooperate closely with each other and adjust theiractions according to your needs. The cooperation among team members whounderstand and work according to agile principles will work differently to aclassic team in software development. They will all contribute not only theirknowledge but help each other solving problems and suggesting alternativeideas to challenging issues. The decision-making process will becollaborative, not hierarchical.The flexibility and adaptability in the collaboration between the client, theproject manager and developers are what makes the process agile. For a productowner, the ability to adjust to recommendation puts his project on the righttrack. The same goes for the project manager and the team, who adapt to therequirements (often changing) of the product owner and together, they find themost suitable solution to fulfill them. If anything needs clarification, allthose participating in the project make themselves available and communicateregularly.
Software development process
Estimations of time and costs for the agile project will initially seem quiteambiguous. This may be stressful, but gets quickly alleviated by tangibleeffects of work. Agile software development produces working pieces ofsoftware very quickly. We can get a couple of simple features or a loggingscreen up and running within the first weeks.The further the project progresses, the more accurate estimations can be doneregarding the remaining work.After the initial weeks of intensive work, the active involvement of theclient is significantly reduced. If few or no major changes are needed, theproduct owner is informed about the progress and shown the work effects forapproval. They still attend meetings at the start/end of each iteration toapprove the completed work and plan the next stage.A few weeks before the projected completion of software development, theproduct should be ready for final testing, approvals and launch. Introducingchanges at this stage is still possible, but this could mean delays or evenadding new iterations to the project, depending on how significant the changesare. The client should be made aware of this fact.
Should I use Agile in my upcoming software development project?
No matter which framework you choose – Scrum, Extreme Programming, Kanban orsomething else – using Agile is always the right decision. You can even usethe principles from two approaches and take what’s best for you from both.That is called a hybrid Agile methodology.When picking a framework, you should take a closer look at your organizationand the software development company you will collaborate with. Also, thinkabout the details of your project. What are the biggest risks regarding thestrategy you planned? Is your product complicated and rich in advancedfeatures? Or maybe you care about a short time-to-market? Answering thesequestions will help you determine the risks and chances you should addresswith the right workflow methodology.The details of your company also matter – Agile can be a great projectmanagement tool for any startup or enterprise, but you need to adjust it tothe size, structure and style of working.
Explanation on Agile Software Development methodology
Agile software development methodology is a step by step approached in solvingissue that used self-organizing, cross functional teams. It has this planningthat adapt time boxed approached. It encourage rapid response and flexible toany changes needed. The concept behind this is framework.Framework that promotes interaction to be ready by unforeseen situations,develop through-out input and output.Agility must have these values to ensure development. 1. Adaptability 2. Transparency 3. Simplicity 4. UnityIt encourage to follow and do the following thinking; 1. Strategy 2. Release 3. Iteration 4. Daily 5. Continuous These characteristic must be visible to ensure burndown, velocity, burnout,test are met to make this software working.
Explanation on Agile Software Development methodology
Hello Eldreda,The methodology of agile methods is quite significant, because it is notfocusing so much on their weight but on their first orientation of people andadaptive nature than predictive. The agile methods always welcome the changes.They try to adapt and thrive on change even to the point of changingthemselves.The architecture of agile method is to get the project organized and moving inthe right direction.Some advantage of agile method are given mentioned below:1. Incremental Deployment2. Building Quality In3. Eliminate Waste4. Gradual emergence of architecture5. Excellent Visibility6. Right Product7. More EnjoyableThank You.Paul Jolie.Agile vs Waterfall: Which methodology to use in your project?Agile vs. Waterfall is a long debate that has been going on in the globalmarket for quite some time now. Many marketers and agile enthusiasts arguethat the waterfall is dead. However, many traditional organizations claim touse it till the day. In fact, almost 51% of the organizations have found to beusing waterfall methodology, either often or always in software development.Whatever the scenario may be, the reality is that every software developmentproject has its needs and requirements, and that could be fulfilled with aspecific development approach. Today, we will be talking about agile vs.waterfall methodology and their pros and cons to help you choose the perfectdevelopment approach.Let’s get started!

The Agile software development cycle
The Agile software development cycle can be broken down into six steps:concept, inception, iteration/construction, release, production andretirement.The first step, concept, involves the identification of business opportunitiesin each potential project as well as an estimation of the time and work thatwill be required to complete the project. This information can then be used toprioritize projects and discern which ones are worth pursuing based ontechnical and economic feasibility.During the second step, inception, team members are identified, funding isestablished and the initial requirements are discussed with the customer. Atimeline should also be created that outlines the various responsibilities ofteams and clearly defines when work is expected to be completed for eachsprint. A sprint is a set period of time during which specific work has to becompleted and made ready for review.A visualization of the Agile software development cycleThe third step, iteration/construction, is when teams start creating workingsoftware based on requirements and continuous feedback. The Agile softwaredevelopment cycle relies on iterations — or single development cycles — thatbuild upon each other and lead into the next step of the overall developmentprocess until the project is completed. Each iteration typically lasts betweentwo to four weeks, with a set completion date. The goal is to have a workingproduct to launch at the end of each iteration.Multiple iterations occur throughout the development cycle and they eachpossess their own workflow. A typical iteration flow consists of: * defining requirements based on the product backlog, sprint backlog and customer and stakeholder feedback; * developing software based on the set requirements; * conducting quality assurance testing, internal and external training and documentation; * delivering and integrating the working product into production; and * gathering customer and stakeholder feedback on the iteration in order to define new requirements for the next sprint.The fourth step, release, involves final quality assurance testing, resolutionof any remaining defects, finalization of the system and user documentationand, at the end, release of the final iteration into production.After the release, the fifth step, production, focuses on the ongoing supportnecessary to maintain the software. The development teams must keep thesoftware running smoothly while also teaching users exactly how to use it. Theproduction phase continues until the support has ended or the product isplanned for retirement.The final step, retirement, incorporates all end-of-life activities, such asnotifying customers and final migration. The system release must be removedfrom production. This is usually done when a system needs to be replaced by anew release or if the system becomes outdated, unnecessary or starts to goagainst the business model.Throughout the Agile cycle, different features can be added to the productbacklog, but the entire process should consist of repeating each step over andover until every item in the backlog has been satisfied. This makes the Agilecycle more of a loop than a linear process. At any time, an enterprise canhave multiple projects occurring simultaneously with iterations that arelogged on different product lines and a variety of internal and externalcustomers providing different business needs.
Defining the Agile Software Development Process
In the 1990s, some brilliant programmers came up with a way to meet theindustry’s growing demands for quick turnaround solutions. They divided thesoftware development life cycle into smaller manageable chunks. Focusing on1-2 features, these chunks are time-boxed for development over 2-3 weeks.Agile takes the lead from the Waterfall model. But it is different as youdon’t complete a particular phase for all features and specifications in one-go. Instead, you pick and choose the features you can manage to develop in 2-3weeks (called sprints).Then you run the entire cycle of analysis, design, development, testing, andimplementation on those features in one-go. So, this makes Agile development avery popular choice.Because it ensures that product features are rapidly developed, giving roomfor the quicker launch of products in the market. Sounds fascinating right?
