I must agree that Test::Nginx lacks documents and tutorials :P

I myself seldom or never use that. I cannot remember why I did
introduce that. From the code, it indeed can be replaced by the "eval"
filter.

Oh, I'm sorry about that. The assumption that I originally made was
that we should try our best to make our test cases independent of each
other. Exceptions was supposed to be rare (and indeed so in our test
suites), hence the no_shuffle() switch and the default "shuffle on"
behavior.

This is usually done this way:
use Test::Nginx::Socket;
plan tests => 2 * blocks();
our $config = <<_EOC_;
location /foo {
...
}
_EOC_
run_tests();
__DATA__
=== TEST 1:
--- config eval: $::config
--- request: GET /foo?bar=1
--- response_body_like: xxxx
=== TEST 2:
--- config eval: $::config
--- request: PUT /foo?baz=3
--- response_body
yyyyy

There is a repeat_each() mechanism. Does it fits your need? It fires
the same request multiple times that you specify to the same nginx
instance.
For example:
use Test::Nginx::Socket;
repeat_each(3);
plan tests => repeat_each() * 2 * blocks();
run_tests();
__DATA__
...
The "pipelined_requests" stuff is for testing HTTP 1.1 pipelining
support and what you describe is kinda like HTTP 1.1 keepalive testing
or something more like the repeat_each() stuff that I've demonstrated
above?

Yeah, such discussions are really great and I very much appreciate it ;)
