=====================================

This directory contains interop tests that runs in Google App Engine
as gRPC clients.

Prerequisites

- Set up an [App Engine app](https://appengine.google.com) with your
  choice of a PROJECT_ID.
- Associate your `gcloud` environment with your app:
  ```bash
  # Log into Google Cloud
  $ gcloud auth login

  # Associate this codebase with a GAE project
  $ gcloud config set project PROJECT_ID
  ```

Running the tests in GAE
==========================

You can run the gradle task to execute the interop tests.
```bash
# cd into gae-jdk8
$ ../../gradlew runInteropTestRemote

# Or run one of these from the root gRPC Java directory:
$ ./gradlew :grpc-gae-interop-testing-jdk8:runInteropTestRemote
```

You can also browse to `http://${PROJECT_ID}.appspot.google.com` to
see the result of the interop test.
