This class provides an instrumented implementation of the Observer protocol suitable for testing.
This class provides an instrumented implementation of the Observer protocol suitable for testing systems that use Observer. Each instance receives a unique (per process) integer identifier at construction, and keeps count of the number of records that it has published, as well as the contents of the most recently published record and context.
By default, the publish method prints no diagnostic information to the bsl::ostream supplied at construction. This diagnostic information can be enabled by a call to setVerbose with a non-zero argument. A subsequent call to setVerbose with a zero argument will restore the default behavior of publish.
