Agile Testing Interview Questions And Answers

1. What is the difference between burn-up and burn-down charts?Answer: Burn-up and burn-down charts are used to keep track of the progress of the project.Burn-up charts represent how much work has been completed in any project whereas Burn-down chart represents the remaining work in a project.

2. Explain the Iterative and Incremental Development in Agile?Answer: Iterative Development: Software is developed and delivered to the customer and based on the feedback again developed in cycles or releases and sprints. Say in Release 1 software is developed in 5 sprints and delivered to the customer. Now the customer wants some changes, then development team plan for 2nd release which can be completed in some sprints and so on.

Incremental Development: Software is developed in parts or increments. In each increment a portion of the complete requirement is delivered.

3. What is the Application Binary Interface?Answer: Application Binary Interface or ABI defines an interface for complied application programs or we can say it describes the low-level interface between an application and the operating system.

4. What qualities should a good Agile tester have?Answer: The agile tester should be able to understand the requirements quickly.They should know Agile concepts and principals.As requirements keep changing, testers should understand the risk involved in it.The agile tester should be able to prioritize the work based on the requirements.Communication is a must for an agile tester as it requires constant communication with developers and business associates.

5. How a tracer bullet can be used?Answer: Tracer bullet can be used as a spike with the current architecture or the current set of best practices. The purpose of a tracer bullet is to examine how an end-to-end process will work and examine feasibility.Tracer ammunition, which is a part of bullet built with a small pyrotechnic charge in their baseIt is a fictional detective, alter ego of Calvin in the comic strip Calvin and HobbesIt is used in Scrum (software development)to describe a proof-of-concept deliverablePathfinder (library science) – a term for those pathfinders produced by the Library of Congress.

6. Does maximum velocity mean maximum productivity?Answer: No, in an attempt to maximize velocity, a team may, in fact, achieve the opposite. If asked to maximize velocity, a team may skimp on unit or acceptance testing, reduce customer collaboration, skip fixing bugs, minimize re-factoring. While potentially offering short-term improvement (if you can call it that), there will be a negative long-term impact. The goal is not to maximize velocity instead the optimal velocity over time, which takes into account many factors including quality of the end product.

10. What are the different roles in Scrum?Answer: The three scrum roles i.e. Scrum Master, Product Owner, and Team should be explained with the details of a few primary responsibilities of each role. You can add more details as mentioned below for a particular depending on the role you are getting interviewed for.

Product owner – A product owner is actually the stakeholder of the project. He represents the project requirements before the team. He is responsible to have a vision of what to build and convey his detailed vision to the team. He is the starting point of an agile scrum software development project.

Scrum team – Scrum team is formed by the collective contribution of individuals who perform for the accomplishment of a particular project. The team is bound to work for the timely delivery of the requested product.

Scrum Master – Scrum master is the leader and the coach for the scrum team who checks whether the scrum team is executing committed tasks properly. He is also responsible to increase the efficiency and productivity of the team so that they can achieve the sprint goal effectively.

The three agile frameworks are:-

  • Test-driven development
  • Feature-driven development
  • Kanban

15. What do you mean by product burndown chart?Answer: The product burn down chart is the graphical representation of a description that shows implementation and the non-implemented product backlog.

16. Explain what is a story point in the scrum?Answer: It can be considered as a unit to estimate the total efforts required to complete or to do the particular task or implementing a backlog.

17. In what way does agile testing(development) methodology differ from the other testing(development) methodologies?Answer: In Agile methodology, the code is broken into small parts and at a time, only that particular code is worked or tested. Continuous communication on the particular code part is done by a team so that the focus is only on that particular code. This makes the agile process more flexible and focused.

18. What is a Release candidate?Answer: The release candidate is a code /version /build released to make sure that during the last development period, no critical problem is left behind. It is used for testing and is equivalent to the final build.

There are several processor plans involved in this methodology like communication with the team, short strategical changes to get the optimal result, etc. (Company)

29. What do you know about ‘build-breaker?Answer: When sometimes developers accidentally commit bug in the software and when such bug stops the compilation processor generates the warning or failure in the normal execution of testing, we say that the build is broken and the major priority of the tester is to get back again to the normal stage by resolving the bug issue.

This question is to test the analytical capability of the candidate. Answer can be-

Work with the PO to understand the exact requirement to update test cases. Also, understand the risk of changing the requirement. Apart from this one should be able to write generic test plans and test cases. Don’t go for the automation until requirements are finalized.

37. Explain Pair Programming and its benefits?Answer: Pair programming is a technique in which two programmer works as a team in which one programmer writes code and other one reviews that code. They both can switch their roles.


Improved code quality: As the second partner reviews the code simultaneously, it reduces the chances of mistake.Knowledge transfer is easy: One experience partner can teach another partner about the techniques and codes.
