Performance benchmarks usually focus on things other than code coverage.<br>
It is very difficult to write a quality benchmark for a proxy, even<br>
without code coverage as a goal!<br>
<br>
One the other hand, a decent proxy benchmark has enough knobs to tickle<br>
most "interesting" code paths in Squid (or any other proxy). Web<br>
Polygraph[1] (mentioned on this thread earlier) is a good example -- you<br>
can trigger cache revalidation, simulate heavy tailed hit distributions<br>
that stress disk caching, exercise the code that handles aborted<br>
transactions, persistent connection races, etc., etc.<br>
<br>
<br>

<br>
Squid does not come with a comprehensive test suite (yet) and the tests<br>
distributed with Squid are not performance tests (a.k.a. "benchmarks").<br>
If you are looking for functionality rather than performance testing,<br>
then there is Co-Advisor[2]. Squid is tested with Co-Advisor, but those<br>
tests have not been automated (yet).<br>
