Note: #1877 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Investigating.

In looking at this sample, I'm finding a number of issues in the sample around how to locally run the tests, structural issues in which unit tests are starting up the http server, and so on. I'm refactoring some to boost stability and clean up the tests in general.

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (0cbaa0c), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).
