What is a use case?

Test case is a description of steps that a quality assurance expert needs to test a system function. A use case is a detailed walk through of how a user interacts with a system to achieve a particular goal. It focuses on the user's perspective and their objective, outlining the interactions needed to reach their desired outcome. Whether it's booking a flight, editing a document, or monitoring a device, the use case outlines the path to get there. 

Use cases are beneficial for various reasons:

Clear Communication:They provide a clear understanding of how a system should function from the user's perspective. This is helpful for developers, designers, and anyone involved in creating or managing the system.

Identifying Requirements: By outlining user interactions, use cases help identify the functionalities and features a system needs to possess.

Testing and Validation: Use cases can be used to create test scenarios to ensure the system behaves as expected and meets user needs.

What are the different ceremonies in Agile?

Image
Agile ceremonies are formal meetings or events held within an Agile development process to ensure transparency, collaboration, and progress. These recurring gatherings keep everyone informed, aligned, and focused on delivering value throughout the project life-cycle. Here are the four most common Agile ceremonies: 1.Sprint Planning: This meeting marks the beginning of a new sprint (a short development cycle). The development team, along with the product owner, collaboratively plan the tasks for the upcoming sprint. Activities: The product owner presents the product backlog, a prioritised list of features and functionalities for the product. The development team selects user stories (requirements) from the top of the backlog and estimates the effort required to complete them within the sprint time-frame. This estimation is often done using relative sizing techniques . The team collaboratively defines clear and measurable goals for the sprint, ensuring everyone is aligned on what needs ...

Difference between blackbox and whitebox tests

Image
The key difference between black box testing and white box testing lies in their approach to examining software functionality. Here's a breakdown to clarify: Black Box Testing: Black box testing, also known as behavioural testing, treats the software as a black box. Testers are concerned with the external behaviour and functionality without considering the internal code structure. Black box testers typically don't require in-depth knowledge of the software's internal code. They focus on requirements, specifications, and user stories. Black box testing is useful for: System testing and user acceptance testing. Usability testing. Smoke testing and sanity testing. Black box testing techniques are: Equivalence partitioning Boundary value analysis Error guessing and User scenario testing These techniques focus on input values, expected outputs, and system behaviour under various conditions. Advantages: Black box testing reflects how actual users interact with the software, i...

Explain STLC with an example?

Image
The Software Testing Life Cycle (STLC) s a set of phases that defines the testing approach for a software development project. It outlines the various activities and tasks involved in ensuring the quality and reliability of the software being developed. The STLC includes the following phases: Requirement Analysis: In this phase, testers analyse the requirements documents to understand what needs to be tested. They identify testable requirements, create test scenarios, and determine the testing scope. Test Planning: Test planning involves defining the test objectives, test strategy, test approach, and resources required for testing. Test plans and schedules are created based on factors such as project timelines, budget, and available resources. Test Case Development: Test cases are developed based on the test scenarios identified during the requirement analysis phase. Test cases outline the steps to be executed, the expected results, and the test data required for each test sce...
