Use Case vs Test Case: Core Differences

In the Software Testing landscape, Use Case and Test Case are the most important terms, and they are somehow related to each other. As these terms are related, they are often apply interchangeably by software professional inadvertently. However, it is important to translate these terms and know their dispute for accurate use. This clause focuses on explaining these two term with model, their advantages, and their divergence.

What is a Use Case

A Use Caseis a detailed description of how a user interacts with a system to achieve a specific goal or task. It is a technique used in software engineering, particularly in requirements gathering, to adumbrate the functional requirement of a system. Use example are typically used to specify the demeanor of a system from the view of its users (or & # 8220; actors & # 8221;).

In Software testing, the term “ use case ” is used to line all the potential steps a exploiter may perform to interact with the scheme. It let you to chalk out all the possible proficiency and how the end-user can use the covering with a set of instructions to the scheme and the expected result of the interaction with the system. It is a list of activeness or event steps typically defining the interaction between an actor and system to accomplish a destination.

Use case also help QAs understand the areas where mistake could occur while interacting with the scheme and design features to solve those erroneousness. A use case is a graphical representation of a document excuse the steps an actor should perform to test the system.

Components of Use Case

Depending on the complexity of the use case, each use case must control the following combination of elements:

1. Actor:A individual someone or a group of people that interact with the system.
2. System:A product/service/software under test.
3. Goal:The successful user outcome.
4. Stakeholder (s):A mortal, group, or company that is directly or indirectly involved in the project and who may affect or get affected by the issue of the project.
5. Chief Actor:A stakeholder who initiates an interaction with the system to reach a finish.
6. Preconditions:The state of a scheme and its environment that must be met before a specific test can be run.
7. Triggers:Events that occur for a use suit to begin.
8. Basic Flow of Success Scenario:A Use case flow that demonstrates the idealistic case in which nothing goes improper.

Use Case Diagram

In the Unified Modelling Language (UML), a use causa diagram is used to create a ocular representation of an real live system. By employ specialized symbols (for Actors, use case) and connectors are required to create a use case diagram.

A use cause is represented by its name in an oval, and the histrion is represented by a stick figure with the name below. Each action between an actor and a use case is correspond by a line.

The Use case diagrams help to specify the basic flow of events in the system. This high-level diagram can help the entire scrum squad to see the system under test and to discuss and specify workflows in the system.

Use case diagrams are generally created by business analysts at the former stage. However, it can be employed at any level of the. This can help the team to think of all the possible scenarios a system can perform. It besides assist to find if there is any scenario missing to be integrated.

Example of a Use Case

Assuming the use example of an online shopping scheme between a customer and marketer through an online shopping application. Here ’ s what the Use Case Diagram would be like.

The above use event diagram depicts an Online shopping scheme consisting of two principal actor: Customer and Seller. Six use cases are place to explicate the high-level functionality of the online shopping scheme.

A customer can view products, add products to drag, checkout, and place orders. A seller can view products, update existing product details and its terms, and add/remove production from inventory.

Here, considering an online shopping scenario initiated by a customer, the following are the details of the elements affect.

• Actor: A Customer.
• Trigger: The client wishes to buy the items via an on-line shopping app.
• Precondition: Network should be available, and the app should be logged in.
• System: Online Shopping App.
• Goal: Complete purchase successfully.
• Stakeholder: App owner.

Best Practices to Create a Use Case

Here are some of the best pattern to follow for creating a use causa:

1. In a use case, each step should exhibit an action.
2. The turn of use cases should be someplace between five to ten for better apprehension and less complexness.
3. Avoid using if argument. if argument comes with an else statement, and employing this would create complexity and confusion. Instead, use verbs like validate and verify. (The scheme verifies the login is valid)
4. Use causa steps should be simple, short, and easy to understand.
5. Do not include UI while creating use cases for any scheme. UI is bound to modify in the Agile framework, and we would not be interested in updating the use case for any UI update.
6. Use instance should show a high level of representation and should not include minor things of the system.
7. Use cases should only excuse the functional piece of the scheme and should not include the designing.

Advantages of Use Case

Creating a use event has many benefits, some of them are:

1. Use causa diagram fall under the functional requirement documentation technique. It is used for defining and direct functional requirements in a scheme.
2. Use cases help assure that the correct system is developed by capturing the requirements from the end user & # 8217; s point of view.
3. It is utilise to model the basic flow of case in a use case.
4. It is used to visualize software designing at a high grade. Large complex applications can be split into pocket-size modules.
5. It is employ to capture the core functionalities of a scheme.
6. It is presented in a simple and non-technical words so that it is easy translate by stakeholders, client, developers, and tester.
7. As Use cases focus on the exploiter of the system, not the scheme itself, existent system demand can be name earlier in the plan procedure.
8. Use cases could serve in later stages as a groundwork for.

What is a Test Case

A Test Caseis a set of conditions or variable that a tester employ to determine whether a scheme or application behaves as expected under specific circumstances. It defines the steps to be executed, the input data to be employ, and the expected results, to verify that the system functions correctly.

A test case is a papers which has a set of conditions/ actions/ steps that are performed on the software covering in order to verify the expected functionality of the feature under test. A test case is generally used to validate whether the developed feature is working as per requirement or not. It is a first-level action that is derived from test scenarios.

Components of Use Case

A test case designing comprises,

1. Test Case Id (which should be unique)
2. Test Case Description
3. Preconditions
4. Test Data
5. Steps to execute
6. Expected Result
7. Actual Result
8. Status
9. Test case Author
10. Test case Executed by
11. Date of execution
12. Comments

To, a QA need basic writing acquisition, attention to detail, a good apprehension of the covering under test, and out of box mentation. A test case should be written in such a way that it can be executed by any testing team member.

Suppose person A is act as a tester and has written test cases for an application. Assuming, some day after. individual A is out of the function, and thither ’ s an urgent motive to run the test cases. Then in such a case, if the test case is not compose properly (no stipulation, uncompleted steps, incorrect test data), it can not be executed by any early squad except person A.

To avoid such dependency, the test case should be written properly, covering all the particular.

Example of a Test Case

Assuming the use event of an online shopping system between a customer and seller through an online shopping coating. Here are some of the examination cases for the use cases mentioned in the previous subdivision.

Best Practices to create a Test Case

Here are some of the best practices to be followed while creating Test Cases:

1. Test case should be simple and leisurely to see so that any team appendage can execute it.
2. Use assertive language while creating a tryout case (Go to the domicile page, Click on the Login push, Enter credential, etc.)
3. Test lawsuit should be created by hold the client & # 8217; s requirements in mind. In the end, you would need exam cases that can be easily understood by the end user and encounter their prospect.
4. All the necessary step should be lend in a test case in the initiative place. Also, the author & # 8217; s name should be added. In future, if there is any difficulty in understanding the steps, the several writer can be approached to fix the same.
5. Test case id and exam case description should be unique, which helps assort them in the bug tracking creature.
6. Ensure all the requirements are mapped to the trial case.
7. Expected Result should have statements containing “ should be ” / “ must be ”.
8. Test case should be generic so that it can be reuse.
9. Test event should invariably be peer-reviewed. If in case any requirement/ step or precondition in a test lawsuit is missing, it can be contribute, making the test suite robust.

Advantages of Test Case

1. Writing test cases at the former stage assist to find gaps in the design.
2. It .
3. It can be reused for future releases. Any new team extremity can refer to this test case to execute it.
4. If there is any feature bestow, append a corresponding test case will secure the test case is executed in all future free, thereby scaling the test suite.
5. It is used to showcase the overall health of the application.
6. It help by giving true results.

Use Case vs Test Case

A use causa draw how a user interacts with a system to attain a goal, concentrate on user behavior and system functionality. A test causa, on the early hand, provides elaborate steps to control the system ’ s behaviour, including inputs, actions, and require results to ensure proper functionality.

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