+# Resolver Tests
+
+This directory has tests and infrastructure for unit tests and GCE
+integration tests of gRPC resolver functionality.
+
+There are two different tests here:
+
+## Resolver unit tests (resolver "component" tests)
+
+These tests run per-change, along with the rest of the grpc unit tests.
+They query a local testing DNS server.
+
+## GCE integration tests
+
+These tests use the same test binary and the same test records
+as the unit tests, but they run against GCE DNS (this is done by
+running the test on a GCE instance and not specifying an authority
+in uris). These tests run in a background job, which needs to be
+actively monitored.
+
+## Making changes to test records
+
+After making a change to `resolver_test_record_groups.yaml`:
+
+1. Increment the "version number" in the `resolver_tests_common_zone_name`
+   DNS zone (this is a yaml field at the top
+   of `resolver_test_record_groups.yaml`).
+
+2. Regenerate projects.
+
+3. From the repo root, run:
+
+```
+$ test/cpp/naming/create_dns_private_zone.sh
+$ test/cpp/naming/private_dns_zone_init.sh
+```
+
+Note that these commands must be ran in environment that
+has access to the grpc-testing GCE project.
+
+If everything runs smoothly, then once the change is merged,
+the GCE DNS integration testing job will transition to the
+new records and continue passing.
