QUESTION

Skipping integration tests in spring boot on VPN DNS availability

Asked 2019-Jun-26 at 04:54

I have a moderately heavy springboot service, it takes 10-15 seconds to boot on a happy flow, and (1-2) minutes to fail on a retry/failover flow. This is ok for my business flows, and is how I expect a healthy service to behave.

I have integration tests (that run some end-to-end flows in my service), that can only test the actual integration status while the test machine (or dev machine) is connected to a specific VPN.

I want to auto skip integration tests if I'm not connected to VPN.

consider the following code

To me, this sounds like something that you shouldn't do in tests at all. Tests (at least IMHO), are supposed to check the business cases and assume that the environment is set up and ready.

Maybe it worth to delegate this functionality to build tool and CI.

Example:

Define a profile in maven (or whatever build tool you use) that will run integration tests that require VPN. Define profile that will run all the rest of integration tests as well. Activate the profile if some system property is available.

In CI tool (like Jenkins) as a part of CI even before you run maven, run the script that will check the VPN connection. Based on the results set the system properties and run maven with these properties. The required profiles will be loaded and all the tests / only tests that do not require VPN will be run.

Update

If you need to make it work from Spring (and it looks like you prefer this way), Spring has a special annotation called @IfProfileValue

By default, it matches against system properties and if the value doesn't match the test gets ignored.

It looks something like this (and note that you can put this annotation on class as well, then it will work for all test methods in the class):

I have two nodes, master and slave. They actually working well except one thing. The master node unable to discover service name. The slave nodes are working perfect without issue.

I have installed the dnstools docker on both nodes. Their /etc/resolv.conf files are exactly same.

I am no sure how it comes, However I re-init the master again and everything works fine, as long as two coredns run on two different nodes. Both can use the dig and return correct response.

I admittedly am not very knowledgable about the deep workings of DNS, so I am not sure why I can do a lookup and dig for the hostname, but not ping it.

Because Service IP addresses are figments of your cluster's imagination, caused by either iptables or ipvs, and don't actually exist. You can see them with iptables -t nat -L -n on any Node that is running kube-proxy (or ipvsadm -ln), as is described by the helpful Debug[-ing] Services page

Since they are not real IPs bound to actual NICs, they don't respond to any traffic other than the port numbers registered in the Service resource. The correct way of testing connectivity against a service is with something like curl or netcat and using the port number upon which you are expecting application traffic to travel.
