When running the tests in aerogear-ios-sdk (./scripts/testing.sh), the test is not marked as failed even if there was an error present in the response from metrics-spi server.

Seen the same behaviour when calling the metrics endpoint separately from the single test. Part of the log:

Executed 1 test, with 0 failures (0 unexpected) in 0.002 (0.007) seconds
