   Since I haven't PRed it yet: The [`zrhoffman/tr-int-test`](/zrhoffman/trafficcontrol/commits/tr-int-test) branch can be used to run the Traffic Router External Tests.
   
   1. Start CDN-in-a-Box
   2. Wait for Traffic Monitor to start, since it is used by some Integration Tests (like AbstractResourceWatcherTest)
   3. Run the Traffic Router External Tests and Integration Tests:
       ```shell
       docker-compose -f docker-compose.traffic-router-test.yml up --build tr-integration-test
       ```
   
   You can also debug the `tr-integration-test` service by setting the `TR_TEST_DEBUG_ENABLE` to `true` in `variables.env`.
   
   Debugging settings to use in Intellij Idea:
   
   - *Listen to remote JVM* instead of *Attach to remote JVM*
   - Enable *Auto restart*, since otherwise the debugger would stop listening after each test
   - Port 8000
   - Make sure the IDE is listening for debug connections before starting the tests or they will all fail.
   
   Edit: And if you're on Linux (no need if using Docker Desktop on Mac or Windows), you'll need to use your own resolver so you can set the IP address for `host.docker.internal` to 172.17.0.1. `host.docker.internal` to 172.17.0.1 in
