Functions ¶

func CheckRoundRobinRPCs ¶

func CheckRoundRobinRPCs(ctx context.Context, client testgrpc.TestServiceClient, addrs []resolver.Address) error

CheckRoundRobinRPCs verifies that EmptyCall RPCs on the given ClientConn, connected to a server exposing the test.grpc_testing.TestService, are roundrobined across the given backend addresses.

Returns a non-nil error if context deadline expires before RPCs start to get roundrobined across the given backends.

func CheckWeightedRoundRobinRPCs ¶

func CheckWeightedRoundRobinRPCs(ctx context.Context, client testgrpc.TestServiceClient, addrs []resolver.Address) error

CheckWeightedRoundRobinRPCs verifies that EmptyCall RPCs on the given ClientConn, connected to a server exposing the test.grpc_testing.TestService, are weighted roundrobined (with randomness) across the given backend addresses.

Returns a non-nil error if context deadline expires before RPCs start to get roundrobined across the given backends.
