End-to-End (e2e) tests

In order to run the e2e tests, first make sure that the app is running with yarn start

You can then run the tests with yarn e2e in another terminal

Problems

e2e cases failed with "Connection refused! Is selenium server started"

Problem:

   { Error [ERR_UNHANDLED_ERROR]: Unhandled error. ([object Object])
   at ClientManager.emit (events.js:140:19)
   at Nightwatch.<anonymous> .....
   .....
   context:
   { message: 'Connection refused! Is selenium server started?\n',
     data: { value: [Object], status: 33 } } }
   .....

Solution:

  - Ensure the required version of selenium package is installed
    yarn list | grep selen

  - Ensure to check selenium server is not running prior to starting the e2e tests.
    ps -ef | grep sele

  - Ensure the server is started when "yarn e2e" is run by running
    ps -ef | grep sele
    502 44074 44068   0 12:23PM ttys008    0:00.06 /usr/bin/java -jar ./node_modules/selenium-server/lib/runner/selenium-server-standalone-3.8.1.jar -port 4444

    Ensure the pid on the output matches the one displayed when yarn e2e was started.  
    Look for line that says "Starting selenium server... started - PID:  44074"
