Details

• Programming Language: Java
• Tools & Framework: Gradle, Junit
• Inputs to be tested are given via Junit tests

Test coverage

• Positive tests: 2, Negative tests: 4

Assumptions

• Case-Sensitivity is observed in the technologies list, e.g., PHP5 & Php5 are considered two different technolgoies.
• https://upb.de/site & https://upb.de/site/site will be valid links
• A link only has to start with https://, e.g., http://upb.de/site will be invalid
• No special characters allowed in link, e.g., http://u@pb.de/site is invalid

Problem description

• The projects takes different site names and the technollogies used in them, the output should simplify the results to report only the differences between the technologies contained in a directory and its parent.

Example:

Input

• https://upb.de/site/drupal -> Drupal, Apache, PHP5, RedHat
• https://upb.de/site/drupal/a -> Drupal, Apache, PHP5, RedHat
• https://upb.de/site/drupal/a/b -> Drupal, Apache, PHP5, RedHat
• https://upb.de/site/drupal/a/c -> Drupal, Apache, PHP5, RedHat
• https://upb.de/site/drupal/a/d/e -> Drupal, Apache, PHP5, RedHat
• https://upb.de/site/drupal/f -> Drupal, Apache, PHP5, RedHat
• https://upb.de/site/drupal/g -> Drupal, Apache, PHP5, RedHat, AngularJS
• https://upb.de/site/jml -> Joomla, Apache, PHP4, AngularJS
• https://upb.de/site/jml/pdfs -> PDF generator
• https://upb.de/site/ -> Apache, PHP5

output

• https://upb.de/site/ -> Apache, PHP5
• https://upb.de/site/drupal/ -> Drupal, RedHat
• https://upb.de/site/drupal/g -> AngularJS
• https://upb.de/site/jml -> Joomla, PHP4, AngularJS
• https://upb.de/site/jml/pdfs -> PDF generator
