What is the difference between Use Case and Test Case?

 

Use cases are designed in the requirement and design phase of the SDLC methodology. Use cases are used to explain and document the interaction that is required between the user and the system to accomplish the user’s task. They are created to help the development team understand the steps that are involved in accomplishing the user’s goals.

A test case is a documented set of instructions that aim to validate whether a software application meets its intended design and functionality. It provides a systematic approach to verify that the software performs as expected under specific conditions.

 

Below are the differences between Use Case and Test Case in tabular format.

 

USE CASE

TEST CASE

1. A use case is a graphical representation of actions that describes the behaviour of a system to do a task.

1. Test Case is a document specifying a set of actions to be performed on the application under test to verify the expected functionality.

2. To create a use case SRS (System Requirement Specification) is required.

2. To write a test case preconditions, test data and steps are required.

3.Use cases are prepared on requirements.

3.Test cases are prepared on Use cases.

4.Require Requirement documents.

4.Test Data, Test Scripts.

5.Business Analyst create use case by collecting the requirement

5.Tester/ QA Analyst create a test case by using use case

6.End user executes the use case

6.Testers executes the test case

7.The purpose of use case is to understand the end-user interaction with the system

7.The purpose of the test case is to validate whether that particular feature is functioning as expected or not.

8.The use case focuses on the end user

8.Test case focuses on the Test result

9.The result of the use case has not been verified

9.The result of a test case is verified with the expected result

10.Use case interacts with the user

10.Test case interacts with the result

WHAT ARE THE BENEFITS IN FOLLOWING DEVOPS PRACTICES?

Image
  INTRO DevOps is a combination of the word’s "development" and "operations." In practice, it signifies a collaboration between development and operations teams. DevOps is a software development methodology that is frequently viewed as a process, a culture, or a framework of principles that enables organizations to deliver products quickly and on an ongoing basis.   KEY PURPOSE OF DEVOPS DevOps was developed to address the problems arising from the traditional practice of having isolated teams—where development, testing, and operations work separately on a single product. This separation often leads to inefficiencies, as each team has distinct priorities, tasks, and schedules that may not align with one another. The primary aim of DevOps is to establish a more unified development cycle. Additionally, embracing a DevOps culture can lead to greater team efficiency, quicker release cycles, and more effective feedback systems.   DEVOPS PRACTICES A few essential practice...

What are different types of non-functional tests

                                                                   Non-functional testing plays a vital role in software testing by examining the non-functional characteristics of a software application. In contrast to functional testing, which checks if the software executes its intended tasks accurately, non-functional testing evaluates the software's performance under different conditions. This encompasses aspects such as performance, scalability, reliability, usability, and security, among other factors. OBJECTIVES OF NON-FUNCTIONAL TEST §   The goals of non-functional testing include enhancing the usability, efficiency, maintainability, and portability of the product. §   It aims to minimize production risks and costs related to the non-functional features of the produc...

WHAT ARE THE DIFFERENT CEREMONIES IN AN AGILE SCRUM TEAM?

Image
       As we embark on our Agile journey, it’s essential to understand the key ceremonies that will guide our workflow and collaboration. These ceremonies are the backbone of our Scrum framework, ensuring that we stay aligned, transparent, and continuously improving.                                                      CEREMONIES IN AN AGILE SCRUM TEAM   In an Agile Scrum team, several key ceremonies play a crucial role in keeping the team aligned and productive. Here are the main ones: The Sprint: A sprint in Scrum is a fixed length of time (usually one month or less) where ideas are turned into value. Sprints occur consecutively until the product is complete (or without end). Often, teams measure their future in sprints. Backlog Refinement (Grooming): This ongoing process involves the team reviewing and prioritizing ...
