• Home grown Graph Implementation using Adjacency list

Quick Run Instruction

Pre-requisite

• JDK 8
• Maven
• Gradle

For running web app

• Git clone this repo and CD to root of that folder
• Run maven command 'mvn clean install tomcat7:run'
• Application will be deployed and initialized with a small person data set. Tomcat server will boot at port 8080. Below is the data set

Verify REST web service calls

• Set Accept header as application/xml or application/json
• GET http://localhost:8080/socialconnection/api/social/1.0/person
• GET http://localhost:8080/socialconnection/api/social/1.0/person?fromName=Foo&toName=Tim
• GET http://localhost:8080/socialconnection/api/social/1.0/person/count?fromName=Foo&toName=Tim

For running FT and UAT test case (Make sure the tomcat server is up at localhost:8080)

• Run command at root of the clone folder 'gradle build'
