What you need to keep in mind is that {{test}} is wiki syntax, it's
not a Velocity/Java API. You print it with Velocity, you don't call
it. So this is all text until the wiki parser parses it, to pass an
array you need to serialize it with the right syntax.
A good way to understand and debug that is to disable wiki parsing in
your Velocity macro as in {{velocity wiki="false"}}. This will gives
you exactly what the wiki parser gets in input.
The problem you have in your example is that you end up with something like:
{{test array=[Chapter 1, Chapter 2, Chapter 3]/}}
and indeed without "" the parser will start at first white space it hits.
All that is mostly for Java based macros (1). One limitation of wiki
based macros is that they don't have any automatic parameters
conversion and they just get all parameters as String, then you parse
it in your macro content (see
http://jira.xwiki.org/browse/XWIKI-13282).
