Based on the official documentation:

kube-proxy reflects services as defined in the Kubernetes API on each node and can do simple TCP, UDP, and SCTP stream forwarding or round robin TCP, UDP, and SCTP forwarding across a set of backends

Basically, it listens for the active Services and forwards them across your cluster.

You can get the list of registered services with:

You're autowiring smsConfig, but you do not appear to provide that @Bean in your test application context.

In addition, you are using @InjectMocks incorrectly - this should be used to inject mock objects into the class under test (your NextelSMSSender class, not SmsConfig).

To resolve, add a @Bean method in your configuration class to provide SmsConfig bean instances.

Replace @InjectMocks from the SmsConfig variable in your test class with @MockBean. SmsConfig is an autowired mock object, and not the class under test.

See Section 41.3.4 - Of the Spring Boot Testing Features for more info:

Spring Boot includes a @MockBean annotation that can be used to define a Mockito mock for a bean inside your ApplicationContext. You can use the annotation to add new beans, or replace a single existing bean definition. The annotation can be used directly on test classes, on fields within your test, or on @Configuration classes and fields. When used on a field, the instance of the created mock will also be injected. Mock beans are automatically reset after each test method.

According to your Error, it seems your service did not respond. Have you tried to open it in a browser, to check if any response there?

Maybe the service you try to call requires you to provide a Static IP from your Webserver, as they only grant access on a IP based level. Means, your IP is blocked until they allow it.

I suggest you use cURL to do your request. This way you get future data to use for debugging, if anything fails. Still here, if the service does not respond, you want get any other information.
