SubAssembies provide a very convenient means to co-locate similar
or related responsibilities into a single place. For example, it's
simple to use a ParsingSubAssembly
and a
RulesSubAssembly
, where the first is responsible
solely for parsing incoming Tuple
streams (log
files for example), and the second applies rules to decide whether a
given Tuple
should be discarded or marked as
bad.
Additionally, in your unit tests you can create a
TestAssertionsSubAssembly
that simply inlines
various ValueAssertions
and
GroupAssertions
. The practice of inlining
Assertions directly in your SubAssemblies is also important, but
sometimes it makes sense to have more tests outside of the business
logic.
