When it comes to writing effective test scenarios, two common approaches are the scenario template and the scenario outline. Both serve the purpose of defining test cases, but they differ in their structure and application. Let’s explore these two techniques and understand when to use each.
Scenario Template
The scenario template is a straightforward way to document test scenarios. It follows a fixed format and provides a clear structure for describing the steps of a test case. Here’s how it works:
- Scenario Title: Start by giving your scenario a descriptive title. This title should summarize what the test case is about.
- Objective: Define the purpose of the test scenario. What are you trying to validate or verify?
- Preconditions: List any necessary conditions or prerequisites for executing the test.
- Steps: Break down the test into individual steps. Each step should be concise and actionable.
- Expected Outcome: Describe the expected result or behavior at the end of the test.
Scenario templates are useful for straightforward test cases where the steps remain consistent across different scenarios. They provide a quick way to document tests without much variation.
Scenario Outline
The scenario outline, on the other hand, is more flexible. It allows you to create a single template that can be customized for multiple test cases. Here’s how it works:
- Scenario Title: Similar to the template, start with a descriptive title.
- Objective: Define the overall purpose of the test scenario.
- Preconditions: List any necessary conditions, just like in the template.
- Steps: Instead of providing specific steps, use placeholders (usually denoted by angle brackets) for dynamic values. For example, “
Given <user> is logged in.” - Examples: Under the scenario outline, provide examples that replace the placeholders with actual values. These examples create individual test cases.
Scenario outlines are ideal when you have similar test scenarios with minor variations. For instance, testing different user roles or input data. By using placeholders, you can generate multiple test cases from a single outline.
Conclusion
Both scenario templates and scenario outlines have their place in software testing. Choose the one that best suits your testing needs. Whether you prefer the rigidity of templates or the flexibility of outlines, remember that clear and well-documented test scenarios are essential for effective testing.
FAQ
What is the main difference between a scenario template and a scenario outline?
A scenario template follows a fixed format with specific steps, while a scenario outline uses placeholders for dynamic values and provides examples for customization.
When should I use a scenario template?
Use a scenario template for straightforward test cases with consistent steps.
When is a scenario outline more suitable?
Choose a scenario outline when you have similar test scenarios that require customization based on different examples or variations.
