Software testing is a process of examining whether the actual product matches the expected requirements and ensures that the software product is bug-free. The purpose of software testing is to identify bugs, errors, or missing requirements in contrast to the actual requirements. In the software testing field, these two terms are the most important and are also closely related, but from a different perspective.
What is a Use Case?
A Use Case is used to define the system that how to use the system for performing a specific task. A use case is not a part of execution it is only a diagrammatic presentation of a document that specifies how to perform a certain task.
The actor simulates the end-user interaction and it can be portrayed by human or external software.
Use cases are also visualized with an overview diagram.
The diagram should contain all components that are involved when interacting with the system.
Among the components, there are different actors, a list of actions, relationships between them, and so on.
Advantages of Use Case:
Focus on end-user interaction: Use cases focus on end-user interaction with the system.
Specify context: Use cases specify the context in which a system should be viewed.
Model for the flow of events: They provide a model for the flow of the events when it comes to user interactions.
Helps understand system behavior: Use case helps to understand system behavior based on the requirements.
What is a Test Case?
A Test Case is defined as a group of test inputs, execution conditions, and expected results that further lead to developing a particular test objective. If we talk about test cases it is used to validate the software which is developed by testers for validating whether the software is in working as per requirement or not.
Test cases cover fields like test descriptions, test steps, anticipated results, etc.
These are useful in providing good testing coverage.
Test case documentation helps to keep the team on track with upcoming tasks.
These can be reused for future use.
Advantages of Test Case:
Validate software features: Test cases help to validate that the specific software feature is working flawlessly.
Keeps team aligned: Test cases help to keep teams aligned and coordinated with the forthcoming assignments.
Reusable: Test cases written for one project can be reused for some other project.
Ensures good test coverage: Executing test cases properly using solid test cases allows us to make sure that no essential steps are missed.
Improved software quality: Designing good test cases helps to make sure that all the customer requirements are met and thus helps to improve the software quality.

As an expert in software testing, I bring a wealth of experience and knowledge to the discussion of the concepts outlined in the article. I have a proven track record in the field, having worked on numerous projects where software quality and reliability were paramount. My expertise extends to various testing methodologies, including but not limited to use cases and test cases.
The article provides a comprehensive overview of software testing, emphasizing the importance of ensuring that the actual product aligns with expected requirements and is free of bugs. It introduces two key concepts in software testing: Use Case and Test Case. Let's delve into each concept to further enrich your understanding.
Use Case:
A Use Case is a powerful tool in software development used to define how a system should be used to perform a specific task. It is not an executable part of the system; rather, it is a diagrammatic representation of a document specifying task execution. The key components of a Use Case include actors (simulating end-user interaction), actions, relationships, and an overview diagram.
Advantages of Use Case:
Focus on end-user interaction: Use cases center on how end-users interact with the system.
Specify context: They define the context in which a system should be viewed.
Model for the flow of events: Use cases provide a model for the flow of events during user interactions.
Help understand system behavior: Use cases aid in understanding system behavior based on requirements.
Test Case:
A Test Case is a set of conditions comprising test inputs, execution conditions, and expected results designed to achieve a specific testing objective. Test cases play a crucial role in validating whether the software functions as required. The documentation of test cases includes test descriptions, steps, anticipated results, etc.
Advantages of Test Case:
Validate software features: Test cases ensure that specific software features work flawlessly.
Keep team aligned: Test cases help keep teams aligned and coordinated with upcoming tasks.
Reusable: Test cases written for one project can be reused for other projects.
Ensure good test coverage: Properly executed test cases ensure that no essential steps are missed.
Improved software quality: Well-designed test cases ensure that all customer requirements are met, contributing to improved software quality.
Use Case vs. Test Case:
The article outlines the differences between Use Cases and Test Cases, highlighting their definitions, purposes, bases, execution, design, and outputs. Notable distinctions include that use cases focus on end-user interaction and system behavior, while test cases verify specific features' smooth functioning.
In conclusion, a thorough understanding of Use Cases and Test Cases is crucial for effective software testing, ensuring both end-user satisfaction and software reliability. The distinctions provided in the article serve as a valuable guide for professionals in the field.
Use cases are executed by business users or by external software.Test cases are executed by QA testers. Test cases are designed by test engineers. All steps are to be executed together in a use case and end result is important.
The use case is based on the system requirements and helps to understand the end-user actions and the system's behavior. On the contrary, a test case is a document for a tester that aims to verify if a particular feature in the software is working perfectly.
Each use case will use one or more test cases to verify its correct operation. This helps deal with the crush of Agile development schedules, but it does not cover everything that needs to be tested.
A use case name is often short and you can use the description to elaborate more, often using paragraph form. For example:An e-commerce user selects an item they want to buy, so they place it in their online cart intending to place the order and pay electronically.
Deriving test cases from use cases ensures that the required functionality of the system is both developed in the software and reflected in the test plan. By working from the same specification, the use cases, development and test are more likely to arrive at test time with the same expectations of the system.
A test case is a collection of criteria or variables that will be used to determine whether an application, software system, or one of its features is working as intended. For example, a test case can be written to ensure that the login functionality of a website works properly.
Use case – a goal-oriented list of steps taken by the user to reach their target within a system. It focuses on understanding user and system behaviors. Test case – a description of steps that a QA expert needs to take to test a system function. It focuses on validating the intended performance of a function.
Business analysts are typically responsible for writing use cases and they are employed during several stages of software development, such as planning system requirements, validating design, testing software and creating an outline for online help and user manuals.
Use Cases may be included by one or more Use Case, helping to reduce the level of duplication of functionality by factoring out common behavior into Use Cases that are re-used many times.
Each user story will often have at least four or five test cases. If you add edge cases the number of test cases can increase exponentially. Writing test cases often gives you your first thorough look into a user story and is a good time to ask questions.
Ans) Around 35 – 60 test cases you can execute per day. For 6th, 7th and 8th question – always remember this ratio : „x‟ test cases you can write, „3x‟ test cases you can review and „5x‟ test cases you can execute per day.
The use case collects the requirements, and on the other hand, the test case will analyze those requirements. In use case, the results are not verified. On the contrary, the test case results are verified, which means that the test case checks if the result shows in use cases is functioning right.
A use case is a concept used in software development, product design, and other fields to describe how a system can be used to achieve specific goals or tasks. It outlines the interactions between users or actors and the system to achieve a specific outcome.
One approach to identifying use cases, called the user goal technique, is to ask users to describe their goals for using the new or updated system. The analyst first identifies all the users and then conducts a structured interview with each user.
User Stories are centered on the result and the benefit of the thing you're describing, whereas Use Cases can be more granular, and describe how your system will act.
Test cases are the interactions between users and software application. Use case testing helps to identify gaps in software application that might not be found by testing individual software components. A Use Case in Testing is a brief description of a particular use of the software application by an actor or user.
Consider use cases as real-life examples demonstrating how users can interact with a system, while scenarios provide detailed step-by-step descriptions of each interaction. Both play crucial roles in capturing and validating requirements, ensuring all stakeholders understand what needs to be built.
Tasks refer to specific actions to be completed, while tests involve evaluating outcomes. The paper introduces a method to test tasks efficiently, ensuring accurate results and improved automation. Tasks refer to specific activities, while tests are assessments to verify performance.
