What is Agile Testing?

The agile testing methodology is based on Agile software development practices. It starts at the beginning of the software project and consists of a continuous method of testing and development.

What is the advantage of Agile methodology in testing?

The advantages of Agile methodology are given below:

  • The bugs or errors are easy to fix as the testing team works together with the development team. This saves money and time, resulting in better development.
  • The whole software development team works closely with the testers. Therefore, the product’s quality is properly analyzed, and it is enhanced.
  • The product documentation is reduced as the agile testers use reusable checklists.
  • It allows obtaining feedback from the end user, and new requirements can be included accordingly.
  • Lesser alterations between the bug fixes.

What are the principles of Agile Testing?

The principles of agile testing are:

  • Continuous testing - Testing is not just a phase but a continuous process where all members of the development team are involved.
  • Constant feedback - Business demands are met through continuous feedback.
  • Total participation - All members of the software team test the application.
  • Short response time - Continuous feedback reduces the response time.
  • Less test documentation – Reusable checklists are used to decrease the documentation.

What are the different types of Agile testing methodologies?

The different Agile Testing methodologies are:

  • Acceptance test-driven development
  • Test-driven development
  • Behaviour-driven development

What is Scrum in Agile testing?

Scrum is a methodology that helps the development team to measure the usability, performance, quality, speed etc. of a product.

The scrum testing in Agile involves the following activities:

  • Sprint meeting – The time required for the development of the component and the items that have to be picked from the backlog are analyzed here.
  • Daily Scrum – The information about the tasks have been completed and the next task that needs to be prepared is done here.
  • Daily work – The tester conducts system test, acceptance test, unit test and automation tests on the daily work of existing sprint.

What is User Acceptance testing in Agile?

User Acceptance Testing is the last stage of the software testing methodology where the testers evaluate whether the product meets the user requirements and specifications. Test cases are developed according to real-world problems. After the satisfaction of the end users, the software is launched in the market.

When is acceptance testing performed in Agile development?

Acceptance testing is performed after each iteration in the Agile environment before the software product is launched.

What is Exploratory testing in Agile?    

Exploratory testing in Agile is an approach through which the testers explore the boundaries of the software product. The method follows an unconventional process of performing test activities like designing new test cases, executing those cases and analysis of the results. The approach emphasizes on the tester’s creativity and skills.

What is BDD testing in Agile?

BDD stands for Behaviour Driven Development in Agile testing. In BDD, the software application is developed and documented according to the behaviour the user expects from it during the interaction.

The developers and testers keep in mind the expectations of the end users and focus on the feedback obtained from them. This helps them to reduce the code complexity, errors, time and allows enhancement of software quality.

How to improve the testing process in Agile?

The testing process in Agile can be improved in the following ways:

  • Quality assurance and testing must be planned properly beforehand. The quality objectives, standards, testing, limitations, scope, risk analysis and execution plan should be prepared earlier.
  • Extreme programming can be used; an approach that is capable of adapting to changing end-user
  • User acceptance testing can help detect bugs and ensure the quality of the product.
  • Conduct formal technical reviews to understand whether the product meets the standards and requirements.

What is the velocity in Agile testing?  

In Agile testing, Velocity is the amount of work the team needs to do in order to reach the sprint objective. After every iteration, the software team calculates the effort estimates of the user stories to know the velocity of the team. This helps them to evaluate the time they will require to complete the whole backlog.

Difference between burn-up and burn-down chart in Agile

A burn-down chart in Agile is used to depict the amount of work remaining to be completed in the project. These are simple and represent the amount of work by a line going towards zero. It hides features such as changes in the software scope. In the case of a fixed scope, the chart is ideal.

A burn-up chart is used to depict the amount of work completed. These aspects are represented by two lines in the graph. It shows the speed of the project and if any new requirements have been implemented. These are ideal for showing the development progress to the clients. Errors are rectified easily by the help of this chart.

Explain sprint backlog and product backlog in Agile.

Sprint backlog in Agile contains the product backlog items that the product backlog has. These items were decided to be included after consultation with the product owner. A sprint backlog helps the team to understand the short term goals needed to complete the project.

A product backlog is a list of aspects that the team has to work on to achieve a certain result. These can be architectural changes, new requirements, bugs or added features. It helps them to plan the tasks they will work in the future.

What is Kanban Agile?

Kanban in Agile is a lean software development process that emphasizes on the work in progress and quick delivery of the software product. It is used in a knowledge work environment where the work needs to be deployed as soon as it is completed. It is a system of analyzing the work that is done and its progress.

Kanban represents the work schedule showing what to perform, how to perform and amount of work to be done.

Describe the Scaled Agile Framework?

Scaled Agile framework is used to apply lean principles for the software. The entire framework is divided into 3 parts: Portfolio, Program and Team. It is useful when the product development time has to be enhanced and the Agile system has to be scaled across the firm. This can support the team while working independently.

What do all agile frameworks have in common?

Agile does not instruct to follow a specific methodology and encourages the teams to work flexibly, incrementally and collectively. However, the most common features among the different Agile frameworks are incremental delivery and incremental product development.

What is the difference between Waterfall and Agile Methodologies?

The differences between waterfall and agile methodologies are given below:

Agile Waterfall
Incremental approach during development. This follows a sequential approach during development.
Changes can be performed after the project starts according to requirements. After the project starts, changes cannot be made easily.
Testing takes place along with the development. Testing is performed after the Build phase.
After each sprint, the test plan is analyzed. The test plan is not analyzed during the testing phase.
As per the requirements, the project details can be altered during the SDLC. The details cannot be altered as it is defined only once by the business analyst.
