It is easy for a newbie to get mixed up with QA terminology. What is a test scenario? What is the difference between test scenarios, test cases, and test scripts? This article will help you figure out everything about creating and using test scenarios.
To make things clear, we need to start by defining the term “scenario”. In software development, a scenario is a user journey while using an application or website. A tester job is to find out how people interact with the functionality and what problems they can face.
A test scenario is a set of manual or automated test cases that helps determine the positive and negative project characteristics. It provides an overview of what needs to be tested by a QA company.
The main purpose of a test scenario is to check the entire system performance from the end-user point of view. A tester needs to put themselves in a user’s shoes. It gives them a clear idea of actual scenarios the software will have to cope with after release.
Before moving on to a detailed test scenario analysis, it’s important to understand how it is different from a test case and test script. In short:
Find more details about the differences in the table below.
Sometimes you need more than one type of documentation. It depends on the project. Each type complements the other and makes the testing process more productive.
A test scenario is a general view of what needs to be tested. It helps:
Thus, it becomes possible to test all core elements and find bugs at the early stages. Thus, users aren’t going to face serious problems after the release.
A test scenario has several advantages for the software testing process:
In some cases, test scenario usage is an ideal decision, while sometimes you can do testing without them. Let’s look at both options.
When to use test scenarios:
When not to use test scenarios:
The skill to create a test scenario surely comes with practice and understanding of a product you are testing. There are the basic steps to follow below.
Step 1. Data collection
Examine the documentation related to a system under test:
Collect as much information about the tested product as possible.
Step 2. Defining test scenarios
List all positive and negative scenarios that cover all (or at least business-critical, depending on the specific request) features of the software. Ensure that these scenarios cover core user flows.
Step 3. Creating traceability matrix
Ensure that each requirement is covered by a test scenario.
Step 4. Approval
Get the scenarios reviewed by a team leader, supervisor, business analyst, or project manager, depending on the organization.
Let’s imagine we need to test a new delivery app. There are several test scenarios with the corresponding test cases you can apply. Find the examples below.
Test Scenario 1. Check the Login functionality.
Test Scenario 2. Check the Search Functionality.
Test Scenario 3. Check the Cart Functionality.
Often, it is enough to list only the test scenarios to assess the scale of the work:
When you have a list of test scenarios, it is clear how much work awaits the team, and you can start prioritizing tasks.
When to Use Test Scenarios, Cases, and Scripts?
You may use some test cases from scenarios in other (new) projects. You may also use the ready-made parts of a test case from one scenario in a completely different test case as well.
With every new functionality, the number of test scenarios increases. The main task of a software tester is to learn how to use them effectively. To do this, you need to mimic real users’ behavior and correctly prioritize the features of the tested software.
