e2e for java server

[Asw Sat]

I am planning to write the pipeline for selenium tests and java appengine server.

I thought 'parallel' is a good choice

step 1, I start my java server

step2, I start my selenium

However, step2 cannot see the server running in step1.  This is because step1 and step2 are parallel, however they are running in different docker container.

Secondly, I thought, I will use the 'services'.  Then use the service in the selenium step.

However, in the services section, I am not able to write the steps and script for running the java server.

Thanks

Any hints on how to run selenium tests after running the java server?
