Behaviour Driven Development (BDD)

This Java desktop application is documented and designed around the behavior a user expects to experience when interacting with it.

  • When a runs the program at App.java they are prompted to either encode or decode.
  • If they choose to decode, they are prompted to enter the word they want to encode. and the corresponding encryption key.
  • Once they provide these info, there are provided with the encrypted word, the same applies for decryption.
  • If they enter any entry which is not 1 or 2, they are notified there are only two option.

Technologies

  • Java is the main language that has been used in this project.
  • Gradle is another powerful tool needed for the program to operate.
