as a general rule put a small description and the actual value in "message"
parameter of the assert
proposal:
Stream.of("expected text 1", "expected text 2")
.forEach(text -> assertTrue("Expected: " + text + " to be present
in " + metric, metric.contains(text)));
Also for an example you don't need to assert that much so just checking
"application:weather_day_status_seconds_count 1.0" can be sufficient for the
demonstration IMHO
