How to Write Test Scenarios That Ensure App Success

Test scenarios provide a structured way to verify system functionality and are essential for ensuring app success.
They focus on what needs to be tested rather than the specific steps to be followed during testing.
Test scenarios make it easier to discuss testing scope with stakeholders and adapt to changing requirements.
Steps to write compelling test scenarios include analyzing requirements, listing user workflows, and prioritizing critical scenarios.
Dependencies and pre-conditions should be identified in test scenarios to avoid unexpected blockers during execution.
Test scenarios should be clear, concise, and reviewed with stakeholders for alignment with business objectives.
Test scenarios and test cases serve different purposes, with test cases providing step-by-step instructions for test execution.
Test scenarios should align with real-world user behavior, cover edge cases, and remain reusable across various test phases.
When writing test scenarios, it is important to avoid excessive details and regularly refresh them to reflect application changes.
Test scenarios are crucial for efficient software testing, offering flexibility and adaptability in complex and dynamic environments.

Spring Boot Essentials: The Interview Cheat Sheet

The DispatcherServlet is the front controller in the Spring MVC framework, routing incoming HTTP requests to appropriate handlers.
Spring Boot simplifies web application development by providing conventions over configurations and automatic setups.
Layered architecture in Spring Boot separates applications into Controller, Service, and Repository layers for better organization.
Maven aids in dependency management by automating the download and management of project libraries.
Maven follows a lifecycle with various phases, where each phase represents a step in the build process.
The @SpringBootApplication annotation conveniently combines multiple annotations in Spring Boot applications.
@Controller returns view names, while @RestController is used to return data directly as the response body.
@RequestMapping, @GetMapping, and @PostMapping are annotations for mapping HTTP requests to specific methods in Spring controllers.
In Spring Boot, a Bean is a Java object managed by the Spring container and can be defined using annotations or configuration classes.
The Inversion of Control (IoC) container in Spring handles object creation, dependency injection, and lifecycle management.
