Examples with FakeTagContext io.grpc.internal.testing.StatsTestUtils.FakeTagContext used on opensource projects

Example 1 with FakeTagContext

use of io.grpc.internal.testing.StatsTestUtils.FakeTagContext in project grpc-java by grpc.

the class AbstractInteropTest method censusContextsPropagated.
