User stories and Use cases are both used to document the requirements. They both capture features of the system. They’re both used by the development team to construct the best solution. They can be used to organize and categorize requirements. And they can be used as references during testing to ensure that the requirements have been met. While user stories and use cases are similar, they also differ in substantial ways. The difference can be challenging to understand and explain, especially if your team is making a transition from a Waterfall software development environment to Agile and Scrum. Each serves a distinct purpose, and they both have their place on a well-run software project. We will try and cover User story vs Use case in this article…
Requirements analysis is an important aspect of software testing. On many traditional projects, this was devoted solely to Business Analysts, who worked closely with their clients to build out a framework onto which development could be executed. With an effective agile project, Quality Assurance engineers should also be part of this phase who can provide significant value. The software code, doesn’t matter how well it’s written, can’t do anything if there are ambiguities in requirements. It’s better to catch the requirement ambiguities and fix them in early development life cycle. It’s a fairly well established theory that the later in the software development life-cycle an issue is discovered, the more expensive it is to fix, and that most often, this cost growth curve is exponential rather than linear. So it’s important to have requirement analysis and catch these incorrect requirements before design specifications.
How do you know the magnitude of a project? How to derive project estimates? How do you know what to build? Or in testing terms, what should be the expected behavior of a software that you are testing? High-level requirements, Software Requirements Specification (SRS), Functional Specification Document (FSD), User Stories or Use cases – whatever you call it in your project – is essentially a requirements documents which forms the basis for software development & testing. A Software requirements specification (SRS) is a description of features and functionalities of a software system to be developed.
How do you ensure test coverage? – One of the most common interview question. After all, client doesn’t want anything skipped in testing & then face the embarrassment of end-user failure in live application. What’s the basis for the Test coverage? Yeah! Requirements – functional, technical & non-functional – every single requirement needs to be tested. What if by mistake the Test team over-looked one of the requirement & didn’t write test cases for it? How will a Test Manager or Client come to know about it? ‘Requirement Traceability Matrix’!
