Every business wants high-quality software to satisfy their customer. However, achieving high-quality software is not an easy task. It requires thorough planning, robust development, and continuous testing.
All this can be achieved by using an agile approach to software development and testing. Let us now try to understand how this methodology works in software testing.
What is agile methodology?
It is a software testing process that is guided by certain values or principles stated in the agile manifesto for software development.
Agile methodology follows an incremental/iterative approach where requirements develop gradually from customers and testing teams.
The main aim of this methodology is to deliver quality software to the client. It is achieved through continuous delivery of value-adding software aided by constant communication with the client and also among team members.
It not only focuses on fast delivery but also the constant delivery of value to customers. In this approach, the software is developed in stages and it allows easy bug identification and fixing.
What are the principles of agile testing?
Below mentioned are the eight principles of this testing method:
• Ensure continuous testing - In this methodology the teams continuously test the product to ensure that the product is continuously progressing. Testing is done along with the development
• Provide continuous feedback - In this methodology testers provide continuous feedback to team members regarding quality improvements
• Involve the whole team- This methodology states that testing is not the only responsibility of testers alone rather it should be done by every team member be it a developer, business analyst, tester, etc.
• Ensure quick feedback – Since the business team participates in each iteration it helps to receive quick feedback on development work
• Deliver high-quality software – With the help of thorough testing, teams can detect and fix issues and vulnerabilities in the software in the same iteration as they are developed. This ensures that quality software is delivered to end-user
• Ensure less documentation – In this methodology teams use a reusable checklist. This methodology lays strong emphasis on current customer needs rather than comprehensive documentation of requirements and instructions.
• Follow test-driven approach - In this methodology, testers evaluate the product at the time of implementation, rather than after implementation (as is the case with traditional testing methods)
• Prioritize customer satisfaction – Customer satisfaction is the top priority as per this methodology. Since customers are exposed to their product during development, they can adapt and update requirements as development progresses. Accordingly, tests can be modified as requirement changes
What are the agile testing quadrants?
The testing quadrants simplifies the tester's efforts and helps them to identify which test to run? when to run a test? and how to run a test?
Quadrant 1 – It is known as an automated quadrant, in this quadrant those tests are performed that helps the team to improve code quality. It includes automated tests like unit and component tests.
Quadrant 2 – It is known as a manual and automated quadrant, In this quadrant tests that are designed to improve business outcomes are performed.
These tests help teams to create a product that drives value for business and customers. It includes running automated and manual functional tests examples, story test, prototype, simulations
Quadrant 3- It is known as a manual quadrant, this quadrant provides feedback for tests in quadrants 1 and 2. The testing team, business owners, and customers realistically use the product to test the user experience and measure business results.
Quadrant 4 - It is known as the tool quadrant and in this quadrant, technology is used to tests the non-functional requirements including security, compatibility, and stability. Tests used in quadrant 4 include stress, performance, and infrastructure testing.
What is the agile testing lifecycle?
Below mentioned are the five phases of the agile testing lifecycle:
• Test Planning: The first step consists of designing a test plan. All the stakeholders such as engineers, designers, clients, and consumers, come together to prepare schedules for the testing
• Test Agility Review: Agility tests are regularly conducted during the period of creation. These are used to assess technology’s success.
• Daily Scrums: At the beginning of each day, the teams conduct a daily stand-up meeting to set priorities for the day. It makes testers understand the research status.
• Impact Assessment: This process is the life-cycle evaluation process that lets testers set expectations for another life-cycle. Users and partners receive the inputs and reviews to conduct an impact assessment.
• Release Readiness: In this process, developers determine which applications are fully integrated and prepared to go live, and which applications must be reverted to the previous development stage.
What are the different types of agile methodologies?
Here are the different types of methodologies:
• Adaptive Software Development (ASD): As the name itself suggests it is an approach that focuses on the adaptive environment while software development. It enables teams to adapt according to the changing environment, collaborate, speculate, and learn throughout the process of software development.
• Feature Driven Development (FDD): It is an iterative and incremental software development process. This methodology is known for short iterations and frequent releases.
It works on a simple five-step process that allows rapid development. It has pre-defined development standards that help the teams to move quickly. It is useful for very big corporations that work on large projects.
• Scaled Agile Framework (SAFe): This framework is for development teams and it emphasizes three pillars i.e.; Team, Program, and Portfolio. It helps teams to collaborate more effectively and helps the organization in achieving quality products.
• Extreme Programming (XP): This methodology is very helpful in projects that require constant changes and quick delivery. It emphasizes continuous product development and customer satisfaction and uses scrum-like cycles or sprints. It includes customer interaction, team member’s participation, quick feedback loops, test-driven growth, and one to three weeks shorter iterations.
Conclusion: Today enterprises are shifting towards more advanced and modern approaches such as agile methodology. This methodology has gained much prominence in the IT world due to the benefits that it provides to IT teams.
With the help of these methodologies, teams can deliver a high-quality product to the customer on time. Leverage agile testing from a next-gen QA and software testing services provider to achieve quality software and to enhance CX.
