Testing is often conducted based on situations, sometimes real and other times imaginary. This is done in order to evaluate the performance of the software under all possible situations. The aim of this article is to help you understand more about Test Scenarios.
Definition Of Test Scenario
A Test Scenario is a scene or a situation that checks a particular function of the program. It may also be done to access how the software performs as a whole, from the viewpoint of its users. When it is not possible to do exhaustive testing, Test Scenarios are developed to cover almost all aspects of the program. Most often this testing is also known as Scenario Testing.
Features Of Test Scenario
Significant features of a Test Scenario are:
- Consists Of Detailed Test Procedure – A test scenario usually has multiple test cases associated with it. These test cases define how the Test Scenario needs to be executed. In other words, a Test Scenario the big picture that needs to be tested through various test cases that provide the actual details.
- One Liner Statement – Test Scenarios are usually a single line statement that tells what needs to be tested. For example, a Test Scenario could be, "Check internet connectivity". This would comprise of multiple test cases that would check the internet connectivity through all the available modes. Hence, a Test Scenario is a broad description of the functionality that needs to be checked.
- Makes For easy Prioritization – when the scope of testing is very large, it becomes difficult to test everything. In such cases, prioritization is a must. This is achieved through the building of Test Scenarios. Those functionalities that are imperative to the success of any software are given more importance and therefore, tested thoroughly. On the other hand, lesser known functions are checked but not rigorously. This way the entire software is covered in testing in a judicious manner.
Benefit Of Test Scenarios
The main benefits of Test scenarios are:
- Prevents Repetitive Testing - A well thought of Test Scenario can tremendously reduce the testing workload. This is because it prevents the testing of the same feature again and again under different testing techniques. It leads to saving of time, money as well as effort.
- Helps Build Better Test Cases – Test cases are built on the basis of Test Scenarios. Hence, a Test Scenario that is carefully developed after deep thoughts will lead to such test cases that are meaningful and checks the software thoroughly with minimum effort.
Scenario Testing is not something that is new to software testing. On the contrary, this phrase was coined by Cem Kaner in the year 2003. From then to now, its popularity has increased in leaps and bounds. And the reason behind its popularity lies in its time and money saving features, without compromising on the quality of the software. A Test scenario is in fact, a very important component of testing. It guides the test cases and lays down the groundwork for detailed steps that need to be followed. Finally, quite often people confuse a test case and a Test Scenario. In this regards, the ground rule is that a test case is dependent on the Test Scenario and not vice-versa.
