Questions on NotifyBuilder

[berhack <ro...@gmail.com>]

This is great for creating coarse grained expectations on routes, but I am
struggling with the documentation.

Hoping the experts can help me answer the questions, based on the given
example:

from(direct:hello).process().to(direct:foo)

from(direct:foo).process().to(direct:bar)

from(direct:bar).multicast/recipientlist

1) on creation within a CamelSpringTestSupport test, does it matter where we
create the notify builder?  I guess as long as it is before sending message
to direct:hello?  Can camel context be already started?  What about waiting
for matches to return?  I guess we do that after sending the message?

2) What is considered "completed" for an exchange anyway?  If I create my NB
with .from(direct:hello).whenCompleted(1) will that match after it passes
through direct:foo?  Or direct:bar?  Maybe this depends on whether a new
exchange is created between direct invocations, I could not find info on
this either.

3) If I create an NB from direct:foo, but start the messaging from
direct:hello, will that still match?  I could not get this to work (matching
times out).

4) Related to #2, in the multicast or recipientlist pattern, when will
whenCompleted(1) match?  Will it match as soon as the exchange is routed to
the multicast or recipientlist, or when the route completes.

Yeah you can create NotifyBuilder in your test method, even after
CamelContext has been started.

Read the javadoc. Completed is when the exchange is completed being routed.
Notice there is a difference between completed vs done. See the javadoc.

Read the javadoc. from is where the exchange originates from (eg where
it was first created)

These EIPs creates new sub exchanges which is also counted in the completed.
