The target can be provided on the command line to avoid needing to recompile
the example just to change where the server is located. We use a target instead
of addresses as that is the approach we have wanted to encourage for a while
since it allows choosing alternative name resolvers.
We typically encourage injecting Channels, not ManagedChannels, which has the
added benefit of simplifying the example. Less indirection makes for a better
example.
Swapping to target string could be done to examples-tls and examples-gauth as
well, but it would be much more invasive to the tls example and the gauth
example would need proper testing after the change.
This reverts commit ac52e27b2a.
See #5665. Right now it is not any more informative than the header
example, and it encourages some practices I'd rather avoid. It will get
re-added later with improvements.
Spies are really magical and easily produce unexpected results. Using them in
tests can easily yield tests that don't do what you think they do. Delegation
is much safer when possible.
Delegation doesn't work when methods `return true`, final methods, and with
restricted visibility, though. So CensusModulesTest and
MaxConnectionIdleManagerTest are left as-is.
The current check in ServerCallImpl is theoretically unsafe (#3059). Move that check into the stub, and expand the unit tests to cover other interesting edge cases on the server side:
client sends one, but zero requests received at onHalfClose
client sends one, but > 1 requests received at onHalfClose
server sends one, but zero responses sent at onComplete
server sends one, but > 1 responses sent via onNext

migrated simple tests using `GrpcServerRule`.
Kept the low level in-process channel setup and tear down code for the RouteGuide example to show how users can use in-process directly to set more custom channel builder options when needed.
resolves#2490
Discovered when importing grpc to internal repo:
1. ErrorProne: Compound assignments from floating point to integral
types hide dangerous casts.
2. found raw type: io.grpc.ManagedChannelBuilder missing type arguments
for generic class io.grpc.ManagedChannelBuilder<T>
