Agile Testing Interview Questions

 
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 Kanban and scrum is known as Scrum-ban. Wherever there are unexpected user story 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.

 
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.
 
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.

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.
