Agile Testing vs Traditional Testing: Key Differences and Benefits

It's the final seal of approval, ensuring that the product meets all the predefined criteria and is ready for release. As you can infer, agile development heavily relies on communication within the team. While automated or agile testing has obvious benefits, including improved quality, accelerated delivery, and reduced costs, making the transition from manual to automated testing isn’t an easy task. Whereas, in agile testing, documentation isn’t an essential part of a QA. QA testers, in this case, assimilate the facts that they need in any form, without much documentation, and carry off with the process.

Plus, the crucial role of testers in the development process is dynamic. Enterprises and businesses today focus on delivering high-quality and releasing products much faster. The key difference between traditional automation and Artificial Intelligence depends on the way of making decisions.

This approach allows the team to adapt to changes and deliver high-quality software throughout the development process. In order to understand agile testing, it’s important to understand what the Agile development methodology involves. It’s an umbrella term, encompassing many practices that are quite different from traditional development techniques.

Testers, here, typically test a particular module or a specific task and may not be aware of the potential dependencies of that module on the overall software. There are separate phases for integration testing and system testing. Test automation is a core agile practice and agile projects depend on it. This frees up developers so they can deliver high-quality code frequently. It provides a framework that lets the team maximize its velocity while maintaining high standards.

Traditional Testing Vs. Agile Testing

They should also be able to incorporate new tools and techniques as the project demands. Agile testing often blurs the lines between roles like 'Manual Tester' or 'Automation Tester.' Not sure what we are getting at? Progress is the leading provider of application development and digital experience technologies. His sharp eye for detail ensures everything works perfectly - both in the organization and the software we ship. All requirements for the software are captured in a software requirement specification (SRS) document. Remember, metrics should be used judiciously and in conjunction with qualitative assessments.

Classical testing and Agile QA

Treat bugs in new features and regressions in existing features differently. If a bug surfaces during development, take the time to understand the mistake, fix it, and move on. If a regression appears (i.e., something worked before but doesn't anymore), then it's likely to reappear. Create an automated test to protect against that regression in the future. The primary function of traditional testing is to certify the quality of the products.

Benefits of Traditional Testing

The reason why testers sometimes work on multiple projects is obvious—there is rarely a constant flow of tasks for testing to fill a full-time role. Therefore, it might be hard to convince stakeholders to have a dedicated testing resource allocated to a team. However, there are some reasonable tasks that a tester can do to fill their downtime when not engaging in testing activities. Agile testing, on the other hand, intends to help the team to “Move Forward (release) with working components and fix defects in future iteration”. As agile philosophy prescribes iterative approaches, various quality aspects are determined in every iteration using the agile testing techniques.

Classical testing and Agile QA

Let’s be honest here, once you’ve figured out what agile QA testing is, you’re going to have more questions. This means working with regularity and rhythm, with early and efficient communication taking precedence. Testers essentially need to be proactively agile, self-consciously applying its principals throughout their work. Shanika Wickramasinghe is a software engineer by profession and a graduate in Information Technology. She is an expert in Software Automation Testing and Web Development.


Our definition of agile testing is testing which occurs in and is appropriate to an agile software development environment. Many of the kinds of testing which are appropriate for other software development methodologies are suitable for agile testing – regression testing, feature testing, and so forth. But their methodology – how they fit with the software release cycle; the way that the tests are planned and success is understood – is often different. Global App Testing provides tester supply which is elastic and which entails a rapid turnaround, meaning you can expand your team instantly in the case of tests which can’t be automated. A  traditional development approach might separate team members based on the area they’re working on, and slowly add pieces together to create a finished product.

  • Some, like Rob Mason, go even further and argue that Agile is killing software testing.
  • Before choosing a suitable testing methodology from Agile testing vs traditional testing, it is always better to get to know what are the major characteristics that make one of them different from the other.
  • Agile testing provides ongoing feedback to the teams and to the customers.
  • Product managers lead the team in user story planning and assignment into iterations for coding

    and testing.

  • With proper planning, collaboration, and adaptation, many of these drawbacks can be mitigated.
  • Implementing a robust software testing strategy is the foundation of continuous delivery in any organization.

Working in an agile environmnet can be challenging for testers coming from traditional projects, but by being open, flexible, and adaptive, they will find that an agile team is a wonderful place to be a tester. The art of verbal and written communication is essential in an agile project. One of the projects that I am currently working on consists of 140 User stories, 83 Change requests, 51 Support and 115 tasks in all. It did not take more than two sprints to realize the need for automating this project simultaneously, as it was being developed and tested in parallel.

In most cases, the time allocated to the testing phase is reduced, as there is always a delay in the coding phase that takes more time than expected. When this happens, testing teams feel the impact as their time for testing is reduced. With agile adoption, there is a heavy reliance on the communication within the team. The testers are always in sync with the development team and plan the testing activity accordingly.

Classical testing and Agile QA

One thought was that one of the key parts of agile is that it is iterative and incremental and we get the opportunity to learn adjust and improve different ideas. Agile has had a huge impact on me both professionally and personally as I've learned the best experiences are agile, both in code and in life. You'll often find me at the intersection of technology, photography, and motorcycling.

The team’s focus is to produce quality software in a limited timeframe that maximizes its value to the customer. Most often, developers will execute manual tests and automated tests. These developers will work with their testers to guarantee the software delivered is of high quality.

In most cases, if you're on a long expedition, traditional testing might work. But if you need to adapt quickly, agile testing is your best choice. Software testers are part of each sprint, testing as features are developed. Conversely, you can go with the methodical and comprehensive traditional testing. Let's understand their key differences, benefits, and the scenarios where each shines. Before choosing a suitable testing methodology from Agile testing vs traditional testing, it is always better to get to know what are the major characteristics that make one of them different from the other.

Defects are entered, and then the software

Classical testing and Agile QA

development team or a committee determines which defects are fixed and which remain in a defect backlog for a future release. If defect fixes are coded, then all affected tests cases are updated and a regression test execution phase retests to ensure

the release quality. The product management team, like Agile, plans and documents the requirements based on customer needs. The plan and requirements documentation moves into the coding phase. Once the features are coded, then the software testers receive a code build to

begin testing. Software testers use the requirements and design documentation when they exist to develop test cases for all the planned features.

IEC IEEE 12207:2017 Systems and software engineering Software life cycle processes

The enabling systems include the manufacturing system to produce the system, support systems such as support equipment to maintain the system, and verification systems to test the system. The practice of concurrent engineering demands that these life-cycle considerations be addressed early and in a coordinated fashion. As a result, the enabling systems are developed concurrently with the operational system so that specific concerns, which may impact other parts of the life cycle, are addressed early in the development process. So far, we've focused on the stages of this cycle that deal with the conceptual and logical design of the data. We've seen how to perform conceptual data modeling using ORM, ER, or UML, and applied the Rmap algorithm to map a conceptual schema to a relational database schema.

  • System Design is a critical stage in the SDLC, where the requirements gathered during the Analysis phase are translated into a detailed technical plan.
  • Sign up for our monthly newsletter to learn about new developments, including resources, insights and more.
  • To manage and control a substantial SDLC initiative, a work breakdown structure (WBS) captures and schedules the work.
  • These changes require SE assessment to avoid loss of system capabilities while under operation.
  • During this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification.

Although these stages differ in detail, they all have a similar sequential format that emphasizes the core activities as noted in Table 1 (concept, production, and utilization/retirement). Once you've completed all testing phases, it's time to deploy your new application for customers to use. After deployment, the launch may involve marketing your new product or service so people know about its existence. If the software is in-house, it may mean implementing the change management process to ensure user training and acceptance. This phase often requires extensive programming skills and knowledge of databases.

How can AWS help you with your SDLC requirements?

On hardware, this is done with frequent program reviews and a customer resident representative(s) (if appropriate). In agile development, the practice is to have the customer representative integrated into the development team. A recent study by the National Research Council (National Research Council 2008) focused on reducing the development time for US Air Force projects. User requirements analysis and agreement is part of the concept stage and is critical to the development of successful systems. Without proper understanding of the user needs, any system runs the risk of being built to solve the wrong problems.

Section 16.7 examines recent extensions to or replacements of relational databases, such as object-oriented capabilities and XML. Section 16.8 provides an introduction to metamodeling, in which schemas themselves are treated as instances of a higher level metaschema. Software is a flexible and malleable medium which facilitates iterative analysis, design, construction, verification, and validation to a greater degree than is usually possible for the purely physical components of a system. Each repetition of an iterative development model adds material (code) to the growing software base, in which the expanded code base is tested, reworked as necessary, and demonstrated to satisfy the requirements for the baseline. Maintenance involves updating an existing software product to fix bugs and ensure reliability.


Other system engineering models, the Traditional (or waterfall), the Vee, Incremental, and spiral are described in those SEBoK articles. Using the Agile Mindset aligned with the Agile Values, the Principles of Agile Development and SAFe Lean-Agile Principles can be applied to the stages of the Agile SE Life Cycle. System management software that makes Red Hat infrastructure easier to deploy, scale, and manage across any environment. This results in more work for the same number of staff, making it hard to get ahead of technological change, innovation, and business demands. These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years. This document provides guidance and recommendations for assurance of a selected claim about the system-of-interest by achieving the claim and showing the achievement.

While the supplied product or service may be seen as the narrow system-of-interest (NSOI) for an acquireracquirer, the acquirer also must incorporate the supporting systems into a wider system-of-interest (WSOI). These supporting systems should be seen as system assets that, when needed, are activated in response to a situation that has emerged in respect to the operation of the NSOI. The collective name for the set of supporting systems is the integrated logistics support (ILS) system. During this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification.

Type of Value Added Products/Services

This stage involves deploying the developed system into the production environment. This includes activities such as system installation, data migration, training end-users, and configuring necessary infrastructure. Implementation requires careful planning and coordination to minimize disruptions and ensure a smooth transition from the old system to the new one. The INCOSE Systems Engineering Handbook shows what each systems engineering process activity entails in the context of designing for affordability and performance.

It has been suggested that information SDLC should not be confused with system (the delivered product) life cycle. The system life cycle begins when the SDLC delivers the final product, that is, when the implementation phase begins. The objective of this activity is to extend as long as possible the life cycle of an existing system. When this is not longer feasible or efficient, the system life cycle terminates and a new SDLC commences. A Generic Life Cycle Model shows a Definition stage, a Realization Stage and a Retirement Stage.

Significance of System Design

It covers management activities related to starting a project, building a team, and managing information through the translation and localization process. This document is independent of the software tools that may be used to produce or manage information for users and applies to both printed, embedded, and mobile information. Much of its guidance is system life cycle processes applicable to information for users of systems of hardware as well as software, systems, and services. It applies to the acquisition of systems, which can be comprised of products, services, or both, as well as to the supply, development, operation, maintenance, and disposal of systems, whether performed internally or externally to an organization.

system life cycle processes

This stage includes the development of detailed designs that brings initial design work into a completed form of specifications. This work includes the specification of interfaces between the system and its intended environment, and a comprehensive evaluation of the systems logistical, maintenance and support requirements. The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification. Many tools have evolved for use in the construction and maintenance of dependable systems, including automated specification and test generators, fault injectors, and fault profilers.

This step involves decomposing the system into pieces, analyzing project goals, breaking down what needs to be created, and engaging users to define requirements. An output artifact does not need to be completely defined to serve as input of object-oriented design; analysis and design may occur in parallel. In practice the results of one activity can feed the other in an iterative process. This may involve training users, deploying hardware, and loading information from the prior system.

system life cycle processes

Today’s complex and increasingly highly connected systems face rapid obsolescence under the stress of technological change, environmental change, and rapidly evolving mission needs. For these systems to remain robust against disruption they must be architected to agilely adapt. To meet these needs, the system must be assessed to apply the process that best serves the system, subsystem or component of the system of interest (SOI).

What is configuration management?

The team iterates through the phases rapidly, delivering only small, incremental software changes in each cycle. They continuously evaluate requirements, plans, and results so that they can respond quickly to change. The agile model is both iterative and incremental, making it more efficient than other process models.
