This is a tutorial that show how hydra can be used to develop test cases with many processes on many nodes interacting in client server type communication. Clone HelloWorld repo using command
git clone --recursive git@github.com:lake-lerna/HelloWorld.git
Make sure Hydra dependencies are met. Place correct hydra.ini file at root directory of cloned repository. A sample hydra.ini file is given at root.
#Installation
./install_hydra.sh
- Using publisher analyzer, test will send 'sendmsg' signal with argument 'x' to publisher.
- Publisher on recieving the signal will send 'x' number of messages to subsciber.
- Using subscriber analyzer, test will send 'getstats' signal to subscriber.
- Subscriber will respond with number 'x' (number of messages received by subscriber from publisher)
- Sent and recieved messages will be compared to decide about success/failure.
./run_helloworld.sh 1555 10
where first argument is publisher port (you can give any available port). while second argument is number of messages to send from publisher to subscriber. Default arguments are port=1555 and num-messages=10.
