Top 10 Agile Interview Questions

Q#1. What is Agile Testing?

Ans. Agile Testing is a practice that a QA follows in a dynamic environment where testing requirements keep changing according to the customer needs. It is done parallel to the development activity where testing team receives frequent small codes from the development team for testing.

Q#2. What is the difference between burn-up and burn-down chart?

Ans. Burn-up and burn-down charts are used to keep track 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.

Q#3.  What is an epic, user stories and task?

Epic: A customer described software feature that is itemized in the product backlog is known as epic. Epics are sub-divided into stories

User Stories: From the client perspective user stories are prepared which defines project or business functions, and it is delivered in a particular sprint as expected.

Task: Further down user stories are broken down into different task.

Q#4. Explain how you can measure the velocity of the sprint with varying team capacity?

When planning a sprint usually, the velocity of the sprint is measured on the basis of professional judgement based on historical data. However, the mathematical formula used to measure the velocity of the sprint are:

  • First – completed story pointsX team capacity: If you measure capacity as a percentage of a 40 hours weeks
  • Second – completed story points/ team capacity: If you measure capacity in man-hours

For our scenario second method is applicable.
