Agile Testing Interview Questions and Answers

Here are a few crucial characteristics of Agile testing methods:

• To ensure tests are done over every simple and even the smallest unit of code that is being developed.
• To create a result oriented testing process that advantages the management and technical aspects of the project.
• Utilize Agile methods of testing over units of code to match the complex requirements at every stage of the development.

Developers have to be adaptive in this case to ensure the successful implementation of the Agile method of testing for the project.

• With a massive development concept, developers have to break it up to facilitate periodic testing.
• Frequent builds and version for developers due to short iterations of test cycles.
• Sudden changes will be required which may create complex situations for the development team.
• Cautious integration of smaller unit pieces to support the significant integration test which may come later.

With Agile testing, developers will have higher control over the code or design that is under development due to the implementation of an incremental and iterative development phase in the project. This will also promote a confident mindset among the team members. The small unit development process also brings the required modularity to the product, making it more reusable.

• Agile promotes incremental methodology, whereas sequential methods are used by conventional techniques.
• Agile focuses on a complete group associated with the project and the required interaction in between them. Compared to which, other ways only emphasize processes and tools.
• Agile focuses on an end product which must be best to the functions but without documentation priority. The conventional methods work opposite it.
• Agile methods include clients as an integral part of the whole project development, whereas this may not be a case for other methodologies.

The Agile testing life cycle is as follows:

• Iteration -1 - This identifies, prioritize the potential project and cinder its feasibility.
• Iteration 0 (Warm Up) – Project initialization and initial input formalities, and the emphasis are on building a unit.
• Construction Iterations - Active client participation in determining the expected output and requirements.
• Release - Start of production, final system testing and end-user training.
• Production – Operation, support and identification of system defects.
• Retirement – Complete system removal from production and user migration.

The product backlog is usually maintained by the owner of the project which contains every requirement and feature list of the products. Whereas, the sprint backlog is a subset of product backlog which includes elements and features related to a particular sprint only.

In Agile, velocity is a metric which is calculated by addition of efforts estimates associated user stories completed in an iteration. The speed will predict how much work Agile can achieve in the sprint and the required time for its completion.

In a pair programming technique, two programmers work as a team in which one writes the code where the other one reviews that code. The roles are switchable throughout the process.

It can benefit the team with:

• Improved code quality and reduced chance of errors.
• Knowledge sharing among team members.

A test stub in Agile is a small code which mimics a specific component in the system and can replace it. The output of the test stub will be the same as the component it will return.

An Agile tester should:

• Be able quickly to proc toss and understand the requirements.
• Know Agile principles and concepts.
• Understand the risks associated with a project as it gets complex.
• Prioritize the work based on the requirements.
• Regular and well-processed communication with the development team and other project associates.
