// This test checks that we output something on test failure where the test
// creates an HttpClient.
// It should not be run as part of a normal test suite, as it is expected to
// fail. See dev/bots/test.dart, which runs this test, checks that it fails,
// and prints the expected warning about HttpClient usage.
// We don't run this for browser tests, since we don't override the behavior
// in browser tests.
