List of Agile Testing Questions and Answers for Interview:-

Define Agile Testing?

Agile testing is a software testing practice that emphasizes testing from the perspective of customers who will utilize the system.

Agile testing does not rigidly follow the pre-defined testing procedures, but rather focuses on testing iteratively against newly developed code until quality is achieved from an end customer’s perspective.

Agile testers:

  • Use reusable checklists to suggest tests.
  • Focus on the essence of the test rather than the incidental details.
  • Use lightweight documentation styles/tools.
  • Capturing test ideas in charters for Exploratory Testing.

What Are The Different Approaches To Testing On Agile Development Projects?

  •  First, you want to test as early as you possibly can because the potential impact of a defect rises exponentially over time (this isn’t always true, but it’s something to be concerned about). In fact, many agile developers prefer a test-first approach.
  •  Second, you want to test as often as possible, and more importantly, as effectively as possible, to increase the chance that you’ll find defects. Although this increases your costs in the short term, studies have shown that greater investment in testing reduces the total cost of ownership of a system due to improved quality.
  •  Third, you want to do just enough testing for your situation: Commercial banking software requires a greater investment in testing than membership administration software for your local Girl Scouts group.
  •  Fourth, pair testing, just like pair programming and modeling with others, is an exceptionally good idea. My general philosophy is that software development is a lot like swimming it’s very dangerous to do it alone.

What Is Application Binary Interface (abi)?

A specification defining requirements for portability of applications in binary forms across different system platforms and environments.

What Is The Difference Between Agile Testing And Rad?

Agile testing is used to test the design in the early stages of the SDLC life cycle.

Rad is an informal name given to agile.

What Are The Key Characteristics Of Agile Testing Methodology?

When adopting agile methods for testing, we ensure that the tests are done over every simple and small unit of code that is being developed. This type of testing has a lot of advantages in the management and technical aspects of the project.

With greater control over the progress that is being made in the development and a demonstratable code at hand every time, the agile methods of testing can prove very useful.

The requirements if complex, can be easily matched up at every stage of development by having agile methods of testing over units of code. This will avoid the possibility of facing requirement conformance mismatches.

What are the Changes That A Development Team Has To Accept If Agile Testing Is On The Cards?

The adaptive nature of the development teams plays a major role if we have to successfully implement an agile method of testing for the project.

  •  Every small change that is being made has to be done in a completely testable form. This means the development of even a very large concept has to be broken up accordingly to facilitate periodic testing.
  • The short iterations of test cycles also would mean that the development team has to come up with frequent builds and versions.
  • When a project is already being tested with other long term methods of testing, a sudden change can be very difficult to be brought in.
  • Unit testing will, in turn, be a major test of integration for each developer and one has to cautiously integrate the smaller pieces of the unit that have already been tested.

In What Kind Of Environments Do The Agile Testing Methodologies Prove Very Successful And Where Do They Don’t?

The agile methods of testing can be a very good way of developing a project which has to have a periodic deliverable and which has very few members in the team with fixed resources. In such scenarios, the Agile methods can help to get the maximum efficiency and stability in the products under development. In such cases, the requirements are not so varied and remain quite constant.

On the other hand, if we consider a very large organization that is developing software or any other product which has a lot of modules and a lot of functional requirements (business logic) then agile methods may just prove to be a hurdle in the development of different modules. So it is not a good idea to adopt agile testing methods in large projects with a wider scope of operations.

How Can Agile Methods Help In Marketing And Business Aspects Of A Product?

The agile methods help in churning out workable code at every stage of development. So marketing of a product can be really effective as the updates to the software/product can come in handy in promotions.

The Inspect and adapt an approach that agile implements can help the product developers to change/add new functionalities over the previously developed layers.

This adaptive approach again can help in keeping the product up-to-date in the market.

How Can It Be Advantageous To The Developers?

Technically the agile methods implement an iterative and incremental development phase in the project.

This means the developers have higher control over the design/code that is under development.

This can be helpful in maintaining a confident mindset among the team members.

Also, the smaller units of development can bring in the much-needed modularity in the product, making it more reusable than the traditional methods can offer.

Key Differences Between Agile And Other Conventional Methodologies?

  •  The product that is developed is based upon incremental, rapid cycles rather than sequential methodology which is deployed by conventional models(INCREMENTAL means each release is tested about its functionality and its increments are small and calculative ).
  •  Where other methods emphasize processes and tools, this method stresses on people and interactions. The customer’s point of view is also given a priority as well as developer and tester also have their say in the upbringing of the product.
  •  The product should be working as thought and expected, but its documentation isn’t given a priority.
  •  The agile method focuses on an end product that is functional and takes into consideration all the conditions but the documentation isn’t a priority on the agile method’s list.
  •  This is also because the developer, tester, and the customer or client are always in conversation and they do know how the product is going to shape up.
  •  All Agile methods include the customer as an integral part of the team, customer clarifies the developer about the need requirements and limitations of the product.

What Is An Agile Testing Life Cycle?

Almost all the other software development life cycles either follow a sequential model (eg waterfall model) or an iterative model. But for processes that are a little more complex, these models find it difficult to tackle the changes which are large in number and continuous.

The agile model was basically made in order to counter these changes effectively and smoothly. This method is a collection of values, principles, and practices that tests and provide the feedback to convert it into a new style of development.

Development life cycle:

  •  Iteration -1 :Identify, prioritize the potential project, and consider its feasibility.
  •  Iteration 0 (Warm-Up): Initiates the project, takes care of the initial input, and the emphasis is on building a unit.
  •  Construction Iterations: The client participates actively and advises about the expected output, requirements, and stuff which is not required by the project.
  •  Release: Deploys first release into production, Final system testing, and trains end-users.
  •  Production: Operates, supports, and identifies defects in the system.
  •  Retirement: Removes the system completely from production and migrates the users.

In What Does The Agile Testing (development) Methodology Differs From The Other Testing (development) Methodologies?

Anytime applying the agile testing methodology, the testers (developers) ensure that the whole process of testing (development) is broke into as small steps as possible and just a small unit of code is tested (developed) in each of these steps.

The team of testers (developers) is communicating consistently the results of their work, and change the short term strategy and even the development plan on the go, based on the results of agile testing.

The agile methodology encourages flexible and rapid response to change which should lead to a better end result.

Can Agile Methodology Be Applied Also In Other Than Software Testing And Development Projects?

While asking these sort of agile testing interview questions, employers try to recognize if you really understand the benefits of this methodology and can see a practical application of it in various areas of business.

To state that this methodology can be, and maybe even should be, applied in all the instances and test cases where we have insufficient entry data, or work in an unknown area, or simply work within a small team, or where many unpredictable variables take place is a good answer.

It is in fact used quite commonly in bio-medicine, biochemistry, or physics. Anyway, it could be used in many other areas.

Understanding Agile Software Development:?

Agile Software Development primarily focuses on an iterative method of development and delivery. The developers and end-users communicate closely and the software is built.

A working piece of software is delivered in a short span of time and based on the feedback more features and capabilities are added. The focus is on satisfying the customer by delivering working software quickly with minimum features and then improvising on it based on the feedback.

The customer is thus closely involved in the Software Design and Development Process. The delivery timelines are short and the new code is built on the previous one. Despite this, the high quality of the product cannot be comprised.

How Is Testing Approach Different In An Agile Development Scenario?

The Testing Strategy and Approach in Agile Development could be very different from traditional bureaucratic methods.

In fact, it could vary with project needs and the project team. In many scenarios, it may make sense to not have a separate testing team. The above statement should be understood carefully. By not having a testing team we do not consider testing to be any less important.

In fact, testing can be done more effectively in a short turn around times, by people who know the system and its objectives very well.

For example, in certain teams, Business Analysts could be doing a few rounds of testing each time the software version is released. Business Analysts understand the Business Requirements of the Software and test it to verify if it meets the requirements.

Developers may test the software. They tend to understand the system better and can verify the test results in a better way. Testing for AGILE Software Development requires innovative thinking and the right mix of people should be chosen for doing the testing.

What To Test?

  • Given the relatively short turn around times in this methodology, it is important that the team is clear on what needs to be tested. Even though close interaction and innovation are advocated rather than processes, sufficient emphasis is given to the testing effort.
  • While each team may have its own group dynamics based on the context, each code has to be unit tested. The developers do the unit testing to ensure that the software unit is functioning correctly.
  • Since the development itself is iterative it is possible that the next release of code was built by modifying the previous one. Hence Regression Testing gains significant importance in these situations.
  • The team tests if the newly added functionality works correctly and that the previously released functionality still works as expected.
  • Test Automation also gains importance due to short delivery timelines. Test Automation may prove effective in ensuring that everything that needs to be tested was covered.
  • It is not necessary that costly tools be purchased to automate testing. Test Automation can be achieved in a relatively cost-effective way by utilizing the various open-source tools or by creating in-house scripts. These scripts can run one or more test cases to exercise a unit of code and verify the results or to test several modules. This would vary with the complexity of the Project and the experience of the Team.

Typical Bugs Found When Doing Agile Testing?

Although nothing is typical about any Agile Development Project and each project may have its own set of complexities, by the very nature of the paradigm bugs may be introduced in the system when a piece of code is modified/enhanced/changed by one or more Developers.

Whenever a piece of code is changed it is possible that bugs have been introduced to it or previously working code is now broken. New bugs/defects can be introduced at every change or old bugs/defects may be reopened.

Steps Taken To Effectively Test In Agile Development Methodology:?
  • As a wise person once said there is no substitute for hard work. The only way one can effectively test is by ensuring Sufficient Test Coverage and Testing Effort Automated or otherwise.
  • The challenge could be a lack of documentation, but the advantage could be close communication between team members thereby resulting in greater clarity of thought and understanding of the system.
  • Each Time Code is changed Regression Testing is done. Test Coverage is ensured by having Automated Scripts and the right mix/combination of People executing the Test Cases.
  • Exploratory Testing may also be encouraged. Exploratory Tests are not pre-designed or pre-defined. Tests are designed and executed immediately. Similarly, ad hoc testing may also be encouraged. Ad-hoc testing is done based on the tester’s experience and skills.
  • While automated Test Cases will ensure that the Test Cases scripted are executed as defined, the team may not have enough time to design and script all the test cases.
Ensuring Software Test Coverage?
  • To ensure that the delivered product meets the end user’s requirements it is important that sufficient testing is done and all scenarios are tested.
  • Sufficient Test Coverage in an Agile Development Scenario may be tricky but with close cooperation and the right team dynamics, it may not be impossible.
  • The objectives of the Project should be clear to the entire team. Many teams advocate Test-Driven Development. At every stage, the Software is tested if it meets the requirements. Every Requirement is translated to a Test Case and Software is validated/ verified. While the Processes and Documentation are not stressed upon sufficient steps are taken to ensure that the software is delivered as per the User Expectations. This implies that each Software delivery should be tested thoroughly before it is released.
  • The timelines being short requires that the person testing the software has sufficient knowledge about the system and its objectives.


An Agile Approach Advocates Which Of The Following Approaches?

Get something business-valuable delivered as quickly as possible, consistent with the right level of quality.

How Is It Different To Traditional Waterfall Or The V Model?

The big difference is that in agile environment, testing is not a phase; it is an activity parallel to development.

  • In agile environment, small features of software are delivered frequently, so testing activity should be parallel to development activity. Testing time is short as we are only testing small features.
  • In the waterfall model, there is a testing phase at the end of the development so, testing is a big effort done after the whole application is developed. Testing time is long as we have to test the whole application.
What Are The Different Methodologies In Agile Testing?

There are various methods present in agile testing such as

  • Scrum
  • Crystal Methodologies
  • DSDM (Dynamic Software Development Method)
  • Feature driven development (FDD)
  • Lean software development
  • Extreme Programming (XP)
What Are The Benefits Of Agile Software Development?

Agile methods grew out of the real-life project experiences of leading software professionals who had experienced the challenges and limitations of traditional waterfall development on project after project.  The approach promoted by agile development is in direct response to the issue associated with traditional software development – both in terms of overall philosophy as well as specific processes.

What Is The Agile Manifesto?

The agile software development emphasizes on four core values:

  • Individual and team interactions over processes and tools.
  • Working software over comprehensive documentation.
  • Customer collaboration over contract negotiation.
  • Responding to change over following a plan.
What Are Some Of The Key Features Of Agile Development?

Some of the key features of agile development are

  • Collective code ownership and freedom to change.
  • Incremental approach (e.g. user stories are incrementally implemented). Automation (e.g. TDD — Test Driven Development).
  • Customer focused (for e.g. internal and external users and business analysts are your immediate customers).
  • Design must be simple.
  • Designing is an ongoing activity with constant re-factoring to achieve the rules of code simplicity like no duplication, verified by automated tests, separation of responsibilities, and minimum number of classes, methods, and lines.
What Is Scrum?

A scrum is an innovative approach to getting work done inefficient way. It is iterative & incremental agile software development method. These iterations are time-boxed with various iterations & each iteration is called Sprint. According to the latest surveys, Scrum is the most popular agile project management methodology in software development. The term Scrum is formed from Rugby.

Scrum is ideally used where highly emergent or rapidly changing requirements. Scrum is basically worked on a self-organizing, cross-functional team. In the overall scrum team, there is no team leader who assigns the task to the team rather whole scrum members work as a team & they decide the task on which they will work on. Also, the problem will be resolve by the team.

What Are The Three Main Roles In Scrum?

The Scrum team consists of three main roles:

  • Product Owner: Manages the product backlog. PO is the voice of the business and creates new features to be developed for the application.
  • Scrum Master: Responsible for managing the sprint, remove any impediments and keeps track of the progress of the project.
  • Scrum Team itself: Composed of developers, designers, and QA. This forms the team which is responsible for delivering high-quality software.
What Is Sprint?

Sprint is a predefined interval or the time frame in which the work has to be completed and make it ready for review or ready for production deployment. This time box usually lies between 2 weeks to 1 month. In our day to day life when we say that we follow 1-month Sprint cycle, it simply means that we work for one month on the tasks and make it ready for review by the end of that month.

Which Of The Following Best Describes The Approach For Determining The Iteration Length?

The team should agree on the length of the iteration taking the size and complexity of the project into consideration.

As Product Owner, Which Of The Listed Guidelines Should You Follow While Creating The Product Backlog?
  • Split high priority customer requirements that are too big into multiple smaller stories.
  • Update the Product Backlog whenever the customer or development team comes up with new requirements.
  • Prioritize the requirements based on business value and risk.

AGILE TESTING Interview Questions and Answers PDF

Mention The Key Difference Between Sprint Backlog And Product Backlog?
  • Product backlog: It contains a list of all desired features and is owned by the product owner.
  • Sprint backlog: It is a subset of the product backlog owned by the development team and commits to deliver it in a sprint. It is created in Sprint Planning Meeting.
Which Scrum Artifact Helps In Tracking Progress?

Sprint burndown chart.

Scrum Master Is Responsible For?

The Scrum process being adopted and used properly.

Which Of These Advocates The Anti-gold-plating Mechanism Of Agile?

Simplicity-the art of maximizing the amount of work not done is essential.

What Is A Test Stub?

A test stub is a bit of code that replaces an undeveloped or fully developed component within a system being tested. The test stub is built such that it mimics the actual component by generating specific known outputs. The stub can be used as a substitute for the actual (fully developed) component for testing purposes. The stub can also be used during testing to isolate system components and troubleshoot problems. A test stub is also known as a test double.

Explain In Agile, Burn-up And Burn-down Chart?

To track the project progress burn up and burn down charts are used

  • Burn up Chart: It shows the progress of stories done over time.
  • Burn down Chart: It shows how much work was left to do overtime.

What Is Dynamic Software Development Method (dsdm)?

DSDM is a Rapid Application Development (RAD) approach to software development and provides an agile project delivery framework. The important aspect of DSDM is that the users are required to be involved actively, and the teams are given the power to make decisions. Frequent delivery of products becomes an active focus with DSDM.

Main Characteristics Of Agile Methodology?

Every person can approach the question from their own view, and perhaps a software tester would give a different answer than a project manager.

Nevertheless, you can list cross-functional team composition, face-to-face communication, solving problems immediately after these are identified, and working solution as a primary metric of progress, as the main characteristics of agile development.

Can We Apply Agile Methodology To Other Areas And Projects?

Employers try to understand if you see the real benefits of agile, and the practical application for various areas of their business.

To say that the methodology can be (and perhaps even should be) applied anytime we have insufficient entry data, or when we work in an unknown area, or simply within a small team, or when many unpredictable variables play the role in the final outcome, would be a good answer. Bio-medicine, biochemistry or physics belong to the fields where we apply agile methodology ever more frequently.

In What way Does The Agile Testing (development) Methodology Differ From The Other Testing (development) Methodologies?

Anytime applying the agile methodology, the testers (developers) ensure that the whole process of testing (development) is broke into as small steps as possible and just a small unit of code is tested (developed) in each of these steps. The team of testers (developers) is communicating consistently the results of their work, and change the short term strategy and even the development plan on the go, based on the results of agile testing. The agile methodology encourages flexible and rapid response to change which should lead to a better end result.

What Is Re-factoring?

Re-factoring is modifying existing code to improve its performance, readability, extensibility, etc. The code’s functionality remains as it is.

What Are The Two Key Factors When Working As A Qa In An Agile Team?

QA can add a lot of value to an agile team because of the different mindset. Testers can and should think about the different possible scenarios to test a story.

However the most important asset that they can bring is:

  • To prevent defect: A should advocate best practices along the way to prevent defects from entering the system in the first place.
  • To provide fast feedback: It is important for developers to know if the new functionality works as expected and if regression tests pass, and they need that feedback quite quickly. QA should provide the results of the tests to developers as soon as possible.
What Are The Disadvantages Of Agile Models?

In the case of some software deliverables, especially the large ones, it is difficult to assess the effort required at the beginning of the software development life cycle.

  • There is a lack of emphasis on necessary designing and documentation.
  • The project can easily get taken off track if the customer representative is not clear what final outcome that they want.
  • Only senior programmers are capable of taking the kind of decisions required during the development process. Hence it has no place for newbie programmers unless combined with experienced resources.
