Difference between waterfall and agile model:
Waterfall- Deadlines are fixed of the project delivery.
Agile- Fast and flexibility of the dead-line
Agile Model-(Fast and Flexible)
1. Agile model is Fast and flexible.
2. In which projects deadline are flexible.
3. It promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.
4. Development and testing activities are concurrent.
5. This model promotes continuous iteration of development and testing throughout the software development life cycle of the project.
1.Project Requirement- To take the understanding of the project & project module.
2. Stories- To makes the stories as per discussion with the client and Team.
3. Test Cases- To makes the test scenarios as per requirement.
4. Tasks- To make the tasks of the project module in which we are broken the module into the small part and estimate the time and assign to the developer team.
5. Iteration- In which we are following the cycle ( planning, developing & Testing)
6. Acceptance Testing- In which testing to be done at client end site.
Scrum-It is agile development method which mainly focus on the task how to manage it in the team. In scrum technique, test must be broken down so that they can be completed within one sprint. It has three roles-
Sprint- Each iteration of a scrum is known as Sprint.
Burn Down Chart- Burn chart shows the graph between the completed task and remaining task statistics.
Advantages of Agile model:
1. Customer,developer and tester continuously interacted to each other
2. Rapidly customer satisfaction and continuous delivery of the software.
3. Regular adaptation to changing circumstances.
4. Between the development changes in requirements are easily handled.
5. Face-to-face conversation between the customer,developer and tester.
6. Working software is delivered frequently (weeks rather than months).
7. Close, daily cooperation between business people and developers
Disadvantages of Agile model:
1. Difficult to Assess the Effort Required at the Beginning of the Software Development Life Cycle
2. Can be Very Demanding on the Users Time
3. Costs can Increase as Testers Required all the Time Instead of at the End
4. The project can easily get taken off track if the customer representative is not clear what final outcome that they want.
1. What is the Process for creating a test script?
Step 1 – Thorough understanding of Project.
Step 2 – Find the all areas that will be tested.
After understanding the requirements, we make a list of what are the areas in this application that will be have to be tested. In other words, we identify the test requirements. The focus in this step is to identify “What” to test.
Step 3 – Once We have the test scenarios, planning how to test them, how to test a particular feature, what data to enter (test data) and what is the expected result.
Once we have the test scenarios, we concentrate next on “How” to test them. This phase involves writing detailed steps about how to test a particular feature, what data to enter (test data) and what is the expected result.
Once these 3 steps are done, we are ready for testing.
2. What is the most challenging situation you had during testing?
Ans- If you came across any such a situation and found any interesting Bug that was difficult to find out or analyzed any project risk accurately before occurring then this could be the answer to this question.
3. What is Risk Based Testing?
Ans- Identifying the critical functionality in the system then deciding the orders in which these functionality to be tested and applying testing.
4. What is Defect Clustering?
Ans- Any small module or functionality may contain more number of defects – concentrate more testing on these functionality.
5. What is Exploratory Testing?
Ans. Exploring the application, understanding the functionality, adding (or) modifying existing test cases for better testing is called exploratory testing.
6. What is Software Configuration Management?
Ans. The process of identifying, Organizing and controlling changes to software development and maintenance.
(or)
A methodology to control and manage a software development project
7. What is Code Walk Through?
Ans. Informal analysis of the program source code to find defects and verify coding techniques.
8. What is Scalability Testing?
Scalability testing is done using load test by changing various software, hardware configurations and testing environment.
9. What is Difference between QA, QC and testing?
Ans. QA?
It is process oriented
Aim is to prevent defects in an application
QC?
Set of activities used to evaluate a developed work product
It is product oriented
Testing?
Executing and verifying application with the intention of finding defects
What is V-model ?
– V- model means Verification and Validation model.
– Each phase must be completed before the next phase begins.
– Testing of the product is planned in parallel with a corresponding phase of development.
V model has the different phases as shown in the above diagram.
Advantages of V-model:
Disadvantages of V-model:
What is Spiral model?
The spiral model has four phases.
1. Planning Phase:
2. Risk Analysis:
3. Engineering Phase:
4. Evaluation phase:
Advantages of Spiral model:
Disadvantages of Spiral model:
