Agile Testing Interview Questions & Answers (2025)

AGILE methodology is a practice followed by QA and is known to promote continuous iteration of development. This testing takes place in the dynamic environment as the requirements keep changing according to the needs of the customer. This testing takes place throughout the development of the software lifecycle of a particular project. Unlike the Waterfall model the testing and development activities are concurrent. The Agile testing is done to the developmental activity in a parallel order and the team testing it receives small codes frequently from the development team.

The agile testing is based on four core values:

1. Giving more importance to the team and individual interactions more than tools and processes
2. Giving more importance to working software more than comprehensive documentation
3. Customer collaboration is above contract negotiation
4. Responding to change above following a plan

The sprint backlog is basically treated as the subset of the backlog of a product that contains requirements and features that are related to that specific sprint only. The Product Backlog is generally maintained by the owner of the project that contains each and every requirement and features of the product.

In the traditional Waterfall model, the testing is generally done at the end of development. However, in Agile methodology, the testing is done in parallel with the developmental activity, which means that as the development progresses so does the testing.

A release burns down the chart is a graph, which is used to depict the release that is still pending and was planned earlier.

Pair programming is basically a technique where two programmers work as part of the team. Here, one programmer is assigned to review the code which the other one is writing the code. The role can be easily switched between the programmers.

The Benefits of Pair Programming:

1. Easy transfer of Knowledge: One experienced partner can always teach the other one about codes and techniques.
2. The code quality is improved: if the second partner is reviewing the code simultaneously, then it simply reduces the chances of mistake.

Incremental Development: Software development is done mainly in increments or more specifically, parts. In every single increment, a part of the complete requirement is to be delivered.

Iterative Development: Software is known to be delivered after developing it, to the customer. Based on the feedback, the software is again developed in cycles and released in sprints. For example, if in Release 1 after five sprints the software is developed and delivered to the customer. After that, if the customer wants changes to be made, then the development team has to make plans for the second release that will be completed in sprints and so on.

  The good qualities of a tester are as follow:

1. An agile tester should have a better and quick understanding of the requirements.
2. Agile principals and concepts should be known by the Agile Tester.
3. He should be able to understand the risk involved in the requirements as they always keep changing.
4. Agile tester, based on the requirements, should know how to prioritize the work involved.
5. An agile tester must be able to communicate with the business associates and developers as their work depends upon better communication.

This question basically tests the analytical capability of the candidate. The answer can be given as:

You need to work with PO and to update the test cases one needs to understand the exact requirement. The agile tester must also understand the risk involved in changing the requirement every time. Keeping all this aside the agile tester must also be able to write the test cases and generic test plan. One must not go for the automation until and unless the requirements are finalized.

Topic: User Stories are created by the business owner that defines the actual business requirement.

Tasks: Tasks are created by the team to accomplish the business requirements development

Epic: A group of related user stories is known as an Epic.

To show the progress of the project, a dashboard is used, and that dashboard is known as Taskboard. It generally contains:

1. User story: The actual business requirement or the user story.
2. To Do: Tasks that can be worked upon.
3. In Progress: Tasks, that is in progress.
4. To Verify: Tasks that are still pending for the testing or verification
5. Done: Tasks that are completed.

It is a technique that involves Test-first development where we first test then goes on to write the complete code for production. After that, the test is run again based on the result so as to refactor the code that fulfills the requirement for the test.

The model of a software development that is the combination of Kanban and Scrum is known as Scrum-ban. Wherever there are unexpected user stories or frequent changes, the Scrumban is used there as maintenance projects. This way the minimum completion time for user stories can be reduced.

Planning poker is also referred to as Scrum poker, which technique based on card estimation basically based on the general agreement.

1) To begin with, either owner or the customer reads the agile user story, and its features are understood by the estimator.

2) Every estimator has planning cards each having a different number on it, like for example 0, 1, 2, 3, 5, 8 and so on. The number on the card stands for the story points or ideal days.

3) The features set by the owner of the product are discussed by the Estimator after selecting the cards based on their estimation.

4) In case a common value is selected, then-then that is the estimate. If it is not the case, then they discuss upon the minimum and maximum value estimation.

5) The above process is repeated until and unless they all reach a general agreement.

As there are advantages, there are disadvantages as well for using an agile model; they are as follows:

1. Focusing on documentation and design is not proper sometimes.
2. If there is even a simple mistake in understanding the guidelines that are provided by the customers, then programmers may have to do it all again or else the outcome of the project will not be satisfying to the customer.
3. Agile model is not that to predict. When encountered with a large project, it is not easy to predict the amount of effort needed in the project.
4. Basically, High-level decisions are catered by Veterans, which is most of the time combined with non-experienced ones. Fresher may have no to little scope to grasp proper knowledge.

Some key principles that differentiate agile testing from others are:

•  The focus is on satisfied customers.
•  The code is clean and bug-free.
•  Changes suggested by the customers are always welcomed.
•  The work is done collectively by developers and whole team business persons.
•  The focus is on essence as opposed to lengthy documentation.
•  Face-to-face conversations are emphasized upon.
•  Sustainable development is promoted.

In what way does agile testing (development) methodology differ from the other testing (development) methodologies?

The methodology followed by Agile testing requires the code to be broken down into small units and only one unit is worked upon or tested at a time. This is not the case with other testing methodologies. This agile process practiced by the team focuses on one particular unit of the code through continuous communication. This method is more flexible.

While using test driven developments, collaborators of class responsibilities, pair programming, daily stand-up meeting, reviews, continuous integration, time-boxed task board, and more, you will easily know that you are simply using the best- agile development.

The main roles in the scrum are:

1) Scrum team: The scrum team comprises of individuals who work together to achieve the best results for any given task. The requested product is delivered by a committed scrum team with a deep bond.

2) Scrum master: As the name suggests, the scrum master is the individual responsible for the proper execution and working of the entire team. The scrum master is a leader as well as a coach. It is his duty to ensure that the team performs at their best, being productive towards both, the scrum as well as the end sprint goal.

3) Product owner: The responsibilities of the product owner include the delivery of a complete and clear picture with respect to what is to be built. The product owner also conveys the same idea to the team.

The last phase of any sprint which is generally held after the sprint review meeting is called the sprint retrospective meeting. The entire team including the scrum master participates in it in order to discuss the good and bad aspects of the sprint. The team confers over the needed improvements, and the discussion lasts for around three hours.

Developers might accidentally execute a bug during the development of the software. When such kinds of bugs generate warnings, result in failed normal executions during testing, or even hamper the compilation process- this irregularity is referred to broken build. The priority of the tester in such cases is to bring the development back to the standard stage by quickly resolving the issue with bugs.

An acceptance test is a formal description of the behavior of a software product which is done by users, customers, or other authorized entities to determine application/software needs and business processes. It is generally used to decides the client's approval regarding any application.

A user story template is a common format used to write user stories that help the user to include key pieces of information about that user story. A user story can be written by anyone.

A regression suite is a set of related regression tests within a regression plan such that it helps development teams concentrate on new functionality while maintaining stability with every new product increment. Then the impact analysis is used to analyzing the impact of changes in the deployed product or application while it's testing.

Scrum Poker is a consensus-based estimating technique. It is a simple tool or technique used by developers for voting on how many story points a story has in a Scrum process in an easy and efficient way.

The challenges that one can face in their Agile project are as follows:

• Lack of planning
• Change resistance to agile
• Clashes with finance
• Legacy HR practices
• Taking a waterfall approach to agile rollouts.

The test that should be done during the sprint can be explained as each sprint in this phase comprises agile practices therefore developers verify unit testing and service integration testing, and also, the testers perform agile acceptance testing.

Yes, I have performed the removal of impediments as a scrum master on behalf of the scrum team as a good Scrum Master will push for permission to remove impediments to team productivity and he will be prepared to ask for forgiveness.

LoadRunner is one of the software that is used for testing. It comes from Micro Focus. Loadrunner is a testing software is used for testing the behavior of a measuring system, applications, and performance under load. One can use LoadRunner to simulate many users at the same time. This is done by making use of application software. Stimulating of multiple users by LoadRunner can also be done when the performance of the major part of the application software is first recorded and then analyzed. This software simulates the activities of a user by generating messages between these application parts. These generated messages are stored in scripts.

Vulnerability Testing is also known by many as Vulnerability Assessment or Analysis. Vulnerability testing is simply a process of defining, detecting, classifying and prioritizing vulnerabilities in network infrastructure, computer system or applications. Vulnerabilities include security loopholes. Vulnerability testing plays a key role in helping in knowing the threat an environment is facing before proper measures are implemented to solve or correct them. To solve these vulnerabilities, both the vulnerable vendor and tools such as network security scanner are used. Every organization or business regardless of the size that is facing cyber-attacks will benefit greatly from vulnerability testing.

Continuous testing goes a long way in checking the business risk coverage. This is considered as the primary goal of continuous testing. This testing offers immediate and detailed information whether releasing a candidate will be too risky to continue to the delivery pipeline. Continuous Testing is the running of automated tests on software to determine the risk related to the software. The feedback gotten after continuous testing of software will determine its release or not. It is used to establish a safety net that prevents software failure headlines. It is also valuable in the development of software as it protects the user experience.
