Greeting Service Kata
A Code Kata intended to practice TDD Outside-In.
Welcome!
Hello developer! 👋 At the HELLO WORLD! Inc. company we are excited to develop and release a new idea into the market! We want to build a new service to send customized greeting messages to our users.
Here you'll find few requirements
- The service have to expose an HTTP API which can be called from other HTTP clients.
- The service can also be used from a command line or an interactive shell.
Try to complete each feature before proceeding to the next one. We like to work iteratively.
Feature One
Just a Greeting
When a greeting message is requested
Then the system will reply with "Hello my friend!"
Feature Two
Greeting a User with a customized message!
When a User with the name Joe request a greeting message
Then the system will reply with a customized message that says:
"Hello Joe!"
Feature Three
Greeting a User by choosing a random greeting message from a set of messages
When a User with the name Joe request a greeting message
Then the system will reply with a customized message that says:
"Hey Joe, nice to see you here!"
List of predefined messages
Hello {User}!Hey {User}, nice to see you here!{User} welcome back!Have a splendid day {User}.
