The internet has become incredibly popular these days, and a lot of individuals and businesses use it frequently for varying needs. From casual browsing to effective marketing, the Internet is now a one-stop place for all industries alike. Thus, to draw in a lot of customers or users, firms must provide quick and easy-to-use online apps or software.
As advancements are being made in the technology sector, the level of user-friendliness and accessibility standards is also increasing, and to fulfill this standard, performing the required test cases is very crucial. This is where test scenario design comes into play, as it helps developers and testers perform required test cases to check the accessibility and user-friendliness of a website or web application.
In this article, we will discuss the significance of test scenario design, and advanced techniques to create desired test cases, and have a look at how certain testing tools such as LambdaTest can enhance the test scenario testing design process by a high margin in accuracy and reliability. Let us start with understanding what test scenarios are.
What is Test Scenario and Test Scenario Design?
A test scenario is a high-level document of some use case or functionality that has to be tested. It can also be viewed as a grouping of activities or circumstances in which a tester may judge whether an application’s aspect or functionality is working as it should.
Unlike detailed test cases, which deal with the exact specification of inputs, expected results, and execution steps, test scenarios are broader and more conceptual. Test scenarios provide a foundation for developing detailed test cases. However, they only outline what shall be tested, not how to perform the tests.
Test Scenario Design
Test scenario design is the process of grouping the high-level conditions or use cases and documenting them. This process includes knowing the functionality of the application, how it can be used, and all the edge cases that need to be tested.
A good test scenario design should provide overall coverage of all the functionalities while also providing insights into the loopholes in testing. Test scenario design acts as a guideline for creating a detailed test case to make the testing process smoother and more efficient. Let us now have a look at the significance of test scenario design.
Significance of Test Scenario Design
The significance of test scenario design is mentioned in the following points:
Ensuring Comprehensive Coverage
One of the significant advantages of effective test-scenario design is that it will help in the complete coverage of an application’s functionality. In addition, testers can identify and document several use cases and conditions for making sure all the features of the application are tested. This will help in finding defects that might have been left out.
Facilitating Efficient Test Case Creation
Well-designed test scenarios give a very distinct roadmap of detailed test cases. They let the testers know precisely what should be tested and why. Hence, they make the entire process of writing detailed test cases much faster. This clarity makes the occurrence of redundant or missed test cases less common, thus making it a more effective and to-the-point testing process.
Communication and Collaboration Enhancement
Designing test scenarios closes the communication gap between the developers and the testers or business analysts. The test scenarios provide a high-level overview of the testing requirements, making the communication gap between technical and non-technical team members negligible. This property of test scenarios allows better cooperation during the testing process and assures similar knowledge about testing goals among the team members.
Identification of areas critical to testing
Test-scenario design identifies the critical areas of the application on which testing needs to be focused. Testers can focus their testing efforts on those areas that are most likely to contain defects or are most critical to the performance of the application by understanding what an application does and its numerous use cases.
Thus, prioritizing testing resources helps ensure quality software development. That is all in the significance of the test scenario, let us now have a look at the advanced techniques to create robust test cases:-
Advanced Techniques to Create Robust Test Cases
There are multiple techniques available to create robust test cases, some of the most prominent techniques are listed below.
Equivalence Partitioning and Boundary Value Analysis
Equivalency partitioning and boundary value analysis are two fundamental methods that aid in the creation of reliable test cases. Using the concept of equivalency partitioning, data is supplied to the system and separated into equal parts. All of these partitions can be tested by a single test case. This technique will reduce the number of test cases while covering all aspects.
On the other hand Boundary value analysis or BVA, will focus on testing these partitions at their boundaries. This technique becomes very important to test the edge cases since defects are generally found at the boundaries of input ranges.
Decision Table Testing
Decision table-based testing is a systematic technique that allows testers to deal with complex business logic. In this approach, the decision table will list all possible conditions against corresponding actions or outputs. Testing with the help of decision tables will ensure that all scenarios, including edge cases and corner cases, are covered by covering all possible combinations of the conditions. This is very useful for applications with complex decision-making processes.
State Transition Testing
State transition testing is a test design technique wherein the different transitions of an application go through several distinct states. The method is applied by determining the various states an application undergoes and all the possible transitions among these states.
Test cases would then be designed to ensure coverage of all possibilities of state transitions. Since this technique targets state-dependent behavior, it is very effective at detecting defects relating to this kind of behavior and ensures an application behaves correctly in all scenarios.
Use Case Testing
Use case testing is a type of testing where test cases are designed based on application use cases. Use cases describe what a user does to or with an application to achieve some goal.
Designing test cases that implement these interactions provides clear steps to ensure an application implements its intended functionality and is user-friendly. Use-case testing effectively finds usability issues and ensures that the application relates to user requirements.
Exploratory Testing
Testers examine the program without using pre-defined test cases in an informal yet effective technique known as exploratory testing. It depends on the creativity, experience, and intuition of a tester in finding out those defects that traditional testing methods might miss. Thus, exploratory testing is very handy for detecting unexpected issues and deeply understanding the behavior of an application.
Risk-Based Testing
Risk-based testing involves prioritizing test efforts on the basis of the risks associated with various parts of the software. The riskier areas of software are identified and tested first for defects, which is then followed by areas having less risk. This technique helps in optimizing test resources and ensures that the most important aspects of an application are thoroughly tested.
