CartSure Input validation using BVA and EP

Business Scenario

Welcome!

You are now continuing your learning journey in the CartSure project as a Software Tester.

After performing functional testing, retesting, and regression testing activities, your manager introduces you to another important testing concept today — Input Validation using Boundary Value Analysis (BVA) and Equivalence Partitioning (EP).

After understanding these techniques, you begin designing input validation test cases for CartSure features by considering different valid, invalid, boundary, and special character inputs.

Once the test cases are prepared, you execute them carefully and analyze the results to verify whether the application correctly accepts valid inputs and rejects invalid data with proper validation messages.

These activities help ensure that CartSure handles user inputs accurately, improves application reliability, and delivers a better user experience.

So, today you will learn how to apply Boundary Value Analysis and Equivalence Partitioning techniques to design effective input validation test cases for the CartSure project.

Task 1: Understanding BRD

Before you start building anything, you need to clearly understand what the client actually wants.So, let’s begin by understanding the BRD (Business Requirement Document) shared by the client.

BRD Full Form is Business Requirement Details.BRD like a plan for building a house. This plan helps the builder understand what to build.In the same way,BRD tells developers what the client wants to build

Click to download BRD : BiteBox_BRD.pdf

After going through BRD list down the Core Features and  Web Pages in the tabulated Format as shown Below.

Task 2: Create WireFrame

Now that you understand the requirements, don’t jump into coding yet. Before development, we always visualize the layout.

Now lets  create a simple wireframe for the homepage.

A wireframe is like a layout plan of a house. Before building, you decide where rooms, doors, and windows will be placed.Similarly, a wireframe helps you plan where elements like headers, images, and buttons will appear on a webpage—before adding design or colours.

Task 3: Code Editor Installation

Good work on completing the planning phase.

Now we will start development. Before that, make sure your system is ready with the required tools.

In this step we will install the VS code editor that will help to Write code efficiently,Organize files , Run and test your application
