How to run a local test on the command line (agents are run locally):

1. Prerequisites: curl and node
2. Edit src/main/resources/application.conf and change masterHost to be the FQDN or IP of the master host. For example:

masterHost = "192.168.1.12"

1. Now run the command './run_test.sh' to get usage.

$ ./run_test.sh
Usage: ./run_test.sh command num
command: start|status|config
num: number of agents

1. Running run_test.sh with a number of agents will return the time each agent took to run a service (start|config|status) and the time when all agents were done reporting their status to the master.

$ ./run_test.sh status 4
{ "service": { "id": "3949eb18-1c7e-459a-aea2-91c82e807af3", "timesPerWorker": [24, 24, 25, 26], "completionTime": 26}}

How to run a local test using the web browser (agents are run locally):

1. Prerequisites: Modern browser like Chrome or Firefox (I used Chrome 29 and Firefox 24)
2. Edit src/main/resources/application.conf and change masterHost to be the FQDN or IP of the master host. For example:

masterHost = "192.168.1.12"

1. Open new terminal window

$ ./run_master.sh

1. Open as many new terminal windows as you would like agents

$ ./run_agent.sh

1. Point your browser to localhost:8090. Click on start or status or config. An alert will display the completionTime.
