:mrdocs:

Set the internal verbose mode of this test observer to the specified (boolean) `flagValue`. The default mode is _not_ verbose. If `flagValue` is non‐zero, calls to `publish` will print appropriate diagnostics to the `bsl::ostream` associated with this test observer. This printing is suppressed if `flagValue` is 0.
