Our services are conditioned by the business and legislative rules that determine how we can design something. The ‘gherkin syntax’ provides a common way of capturing these in a simple format.

The structure of a Gherkin syntax is:

• Feature
• Scenario
• Given, When, Then, And, But (Steps)
• Background
• Scenario outline
• Examples

This is an example from a cash machine

• Feature: Account Holder withdraws cash
• Scenario: Account has sufficient funds
• Given the account balance is £100
• And the card is valid
• And the machine contains enough money
• When the Account Holder requests £20
• Then the ATM should dispense £20
• And the account balance should be £80
• And the card should be returned
