Behavior Driven Development

This is an evolution of Test Driven Development that focuses on the app functionality requirements more than implementation details. There are different interpretations of what this might mean, but I have found value in these tenets:

Video Walkthrough

The video that talks more in depth about behavior driven development, as well as walks through the app example below, can be found at the following link:

Our App Requirements

To showcase this process, we will create an app that does the following:

• Has an endpoint called /teammates that supports GET and POST only
  • The POST endpoint creates a new teammate object and stores it in AWS DynamoDB
  • The POST endpoint supports a body that with a first_name, last_name, and age.
    • first_name must not be empty.
    • last_name must not be empty.
    • age must be a number between 18 and 99.
  • The GET endpoint returns an object with a list of teammates containing all created teammates.
    • Teammate will have the fields:
      • first_name
      • last_name
      • preferred_name
      • age
    • The list will return alphabetically by first_name
• When creating a teammate, consume an API at https://preferredname.com that will give you any preferred names for the first name sent in. Preserve the preferred name if it exists.

Completed Example

There is a branch named completed that will have a working example of what this exercise could look like when completed.
