One widely employed template is the Given/When/Then format, which organises scenarios, actions, and outcomes in a logical sequence. This method aids in visualising task progression and anticipated results.

‍

The scenario-oriented acceptance criteria format, often associated with Gherkin syntax, is rooted in behaviour-driven development (BDD) principles. It structures acceptance criteria into clear scenarios using a Given/When/Then (GWT) sequence:

‍

• Scenario: Defines the specific behaviour or feature being described.

• Given: Establishes the initial state or precondition of the system before the action occurs.

• When: Specifies the precise action taken by the user or the system.

• Then:  Describe the expected outcome or result that should occur as a consequence of the action.

• And: Optionally used to continue any of the preceding statements for additional clarity or detail.

‍

This approach streamlines the definition of acceptance criteria by outlining the entire scenario upfront. It not only guides development but also facilitates efficient testing by clearly defining the conditions under which a feature should operate and the expected results.

‍

By using Gherkin syntax, teams can reduce ambiguity, improve collaboration between stakeholders, and ensure that testing efforts are focused on verifying critical functionalities early in the development cycle.

‍

The Given/When/Then acceptance criteria example 1

User Story: As a customer, I want to track my order status online so that I can stay informed about my purchase delivery.

Acceptance Criteria Example: Order Tracking

Scenario: Track Order Status

‍

• Given: The customer is logged into their account on the website.

• When: The customer navigates to the order tracking section.

• Then: The system displays a list of all recent orders with their current status (e.g., processing, shipped, delivered).

• Given: The customer selects a specific order from the list.

• When: The customer clicks on the order to view details.

• Then: The system shows detailed information about the order, including expected delivery date and current location (if available).

• Given: The customer wants to receive notifications about order status updates.

• When: The customer opts-in for email or SMS notifications.

• Then: The system sends notifications for status changes, such as when the order is shipped or delivered.

• And: If the order delivery encounters an issue, the system provides a contact option for customer support.

‍

This scenario-oriented format using Given/When/Then sequences clarifies each step the user takes and the expected system response. It ensures that the feature meets user needs for tracking order progress effectively and provides clear guidance for development and testing teams.

‍

The Given/When/Then acceptance criteria example 2

User Story: As a user, I want to search for products by category so that I can find items I'm interested in more efficiently.

Acceptance Criteria Example: Product Search

Scenario: Search by Product Category

‍

• Given: The user is on the home page of the e-commerce website.

• When: The user clicks on the "Categories" dropdown menu.

• Then: The system displays a list of available product categories (e.g., Electronics, Clothing, Home & Garden).

• Given: The user selects a specific category from the dropdown menu.

• When: The user enters a keyword or leaves the search field blank.

• Then: The system filters products within the selected category based on the keyword (if provided) or displays all products within the category.

• Given: The user wants to refine their search results further.

• When: The user applies additional filters, such as price range or brand.

• Then: The system updates the displayed products to reflect the applied filters.

• Given: The user finds a product they are interested in.

• When: The user clicks on the product to view details.

• Then: The system navigates to the product detail page, showing comprehensive information, including price, description, and availability.

• And: If the product is out of stock, the system indicates this clearly.

‍

This example illustrates how Given/When/Then acceptance criteria can be structured to define clear steps and expected outcomes for user interactions with a product search feature on an e-commerce website. Each scenario outlines specific actions users can take and the corresponding system responses, ensuring a systematic approach to development and testing.
