How Behavior Driven Development works

Let’s say you need a custom billing system for your business. You have a specific set of requirements, including the ability to generate invoices, track payments, and generate reports. To ensure that the software meets all your requirements, Topvine uses BDD concepts to define the desired behavior of the software.

We start by working with you to define the user stories or scenarios that describe how the billing system should work.

As a user, I should be able to generate an invoice for a customer with a single click.
As a user, I should be able to see a list of unpaid invoices and when they are due.
As a user, I should be able to generate a report that shows all invoices for a specific time period

Next, we would break down each user story or scenario into a set of concrete steps, known as acceptance criteria.

Given that I am logged in to the billing system,
when I click the "Generate Invoice" button for a customer, 
Then a new invoice should be created with the correct customer details. 

Given that I am on the "Unpaid Invoices" page, 
when I sort the list by due date, 
then the invoices should be listed in ascending order based on their due date.

Given that I am on the "Invoices" page, 
when I filter the list by a specific time period, 
then only invoices for that time period should be displayed in the list.

By defining the user stories and acceptance criteria in this way, we can ensure that the billing system meets all your requirements and addresses your unique challenges. We can also use the acceptance criteria to test the software and verify that it meets the desired behavior.

Finally, we turn acceptance criteria into code for your application.

// Define a function that generates an invoice for a customer

function generateInvoice(customer) {

  // Check if the user is logged in to the billing system

  if (isLoggedIn()) {

    // Create a new invoice object with the customer's details

    var invoice = {
      customerName: customer.name,
      customerAddress: customer.address,
      invoiceDate: new Date(),
      // ...other invoice details
    };

    // Add the new invoice to the list of invoices

    addInvoice(invoice);

  } else {

    // If the user is not logged in, display an error message

    showError("You must be logged in to generate an invoice.");
  }
}
