SDLC-STLC-AGILE Flashcards
What is your Responsibility as an SDET?
As a Software Development Engineer in Test (SDET), my responsibilities include:
Automating Tests: Convert manual test scenarios into automated tests using automation tools.
Test Planning: Create test plans that verify user stories and system requirements.
Bug Detection: Identify and document defects in the application.
Perform Various Tests: Participate in different types of testing such as Functional Testing, Regression Testing, and Smoke Testing.
Agile experience in your most recent project?
In our recent project, we ran 2-week sprints with a release every 6 weeks. The team had 5 developers, 3 testers, a Scrum Master, a BA, and a PO.
- Each sprint started with planning and grooming by the PO.
- Daily standups kept us aligned on progress.
- We presented features in a Sprint Demo for feedback.
- We ended with a Retrospective for improvement ideas.
- As an SDET, I presented features in the demo.
STLC vs SDLC?
STLC (Software Testing Life Cycle) focuses only on testing activities, ensuring software quality through planning, execution, and reporting of tests.
SDLC (Software Development Life Cycle), on the other hand, includes the entire software development process, including testing, from initial planning to deployment and maintenance.
Where are your requirement documents?
- Requirements describe user expectations for the software.
- In my project, they are written as Acceptance Criteria for each User Story.
- Product Owners create User Stories, and Business Analysts write the Acceptance Criteria.
- All are stored in Confluence.
Where is the Requirement coming from?
Requirements are provided by the Product Owner (PO), based on input from stake holders customers and competitor analysis.
Is the requirement good or bad?
A good requirement is SMART or INVEST: Specific, Measurable, Attainable, Realistic, and Testable. For example, “As an authorized user, I should log into the app within 2 seconds.”
What is Agile?
- Agile is a flexible approach to software development that focuses on iterative delivery, collaboration, and adaptability to change.
- Agile is a flexible method where requirements can be changed anytime, with continuous feedback and adjustments. Changes are always welcome.
What is Agile Framework?
The Agile framework includes
Roles like Product Owner (PO), Scrum Master (SM), and the Team.
Ceremonies like Sprint Planning, Daily Scrum, Sprint Review, Sprint Retro, and Grooming session.
Artifacts like the Product Backlog, Sprint Backlog, and Burnout Chart.
What is Waterfall methodology?
- Waterfall methodology is a linear software development approach where progress flows through distinct phases sequentially. Each phase must be completed before moving to the next, with no option to go back.
- Waterfall methodology is a linear software development process where each phase—requirements, design, implementation, testing, and maintenance—must be completed before moving to the next, with no returning to previous phases.
Which Agile framework did you use in your previous projects?
I have heard Extreme programming (XP) , Kanban, Feature Driven Development and Scrum.
But I have only worked with scrum.
Relation between Agile and Scrum? What is Scrum?
- Agile is A customer-focused approach for flexible software development.
- Scrum is An Agile framework ideal for projects with fast-changing needs.
Why do we need Agile? Waterfall and Agile?
We need Agile because Waterfall has these issues:
- Requirements are hard to change once set.
- Each phase must finish before the next starts (e.g., testing can’t start before coding ends).
- Customers see the product late, causing delays or outdated software.
Agile is better because:
- Changes are accepted, and feedback is used to improve the product after each sprint.
- It’s an ongoing process where features are built, reviewed, and improved continuously.
What are Different roles in Scrum?
Roles in Scrum:
- Product Owner (PO): Defines the vision, creates user stories, and prioritizes the backlog.
- Scrum Team: Works together to deliver the product on time.
- Scrum Master: Leads and coaches the team, ensuring tasks are completed and improving team productivity.
Describe your scrum team?
Currently in my project we have 11 members in our scrum team. *
1 PO - Stephen.
6 Dev - Linda, Raj, John, James, Ryan, and Karan.
3 Test - Myself, Arjun, and Shelly.
1 SM - Roger.
Have you heard of scrum of scrums?
Yes, Scrum of Scrums is used when multiple teams are involved in a project. It helps teams coordinate, collaborate, and focus on specific agenda items during meetings.
Explain Burn-down and burn-up charts?
Burn-down and burn-up charts track project progress. Burn-up charts show completed work, while burn-down charts display remaining work.
What is Sprint?
A Sprint is a time-boxed phase (2-4 weeks) in Scrum where user stories are divided into modules, delivering a potentially shippable product.
How long is your Sprint?
My current sprint duration is 2 weeks.
Product backlog & Sprint Backlog?
Product backlog contains all features and requirements maintained by the project owner, while
Sprint backlog is a subset of the product backlog, containing features and requirements specific to the current sprint.
Velocity of a sprint and how it is measured?
Velocity measures how much work a team completes in a sprint. It’s calculated by adding the story points of completed tasks. For example, finishing 5 stories worth 3 points each results in a velocity of 15 points per sprint.
How often do you release?
We release features every 3 months based on the product owner’s roadmap. In case of critical defects in production, we perform emergency hotfix releases to resolve customer issues promptly.
What happens when requirements change in middle of sprint?
In Agile, when requirements change mid-sprint, I analyze the impact on completed work to see if it adds or reduces scope. We then re-estimate the user story to update the Level of Effort.
