Here's the scenario: you have code that will emit headers and content, for instance, a front controller. How do you test this?
The answer is remarkably simple, but non-obvious: namespaces.
Now that Zend_Test has shipped, developers are of course asking, "How do I setup my test suite?" Fortunately, after some discussion with my colleagues and a little experimenting on my one, I can answer that now.
#{some tag} or tag:{some tag} to filter by tag; using this more than once will find results that match all tags.year:{year} to filter by year. If you use this multiple times, the last one wins.begin:{year-month-day} to restrict to results beginning on that day. Last one wins.end:{year-month-day} to restrict to results ending on that day. Last one wins.
