NAME

varnishtest – Test program for Varnish

SYNOPSIS

varnishtest [-iklLqv] [-n iter] [-D name=val] [-j jobs] [-t duration] file [file …]

DESCRIPTION

The varnishtest program is a script driven program used to test the Varnish Cache.

The varnishtest program, when started and given one or more script files, can create a number of threads representing backends, some threads representing clients, and a varnishd process. This is then used to simulate a transaction to provoke a specific behavior.

The following options are available:

-D name=val Define macro for use in scripts

-i

Find varnishd in build tree

-j jobs

Run this many tests in parallel

-k

Continue on test failure

-l

Leave temporary vtc.* if test fails

-L

Always leave temporary vtc.*

-n iterations

Run tests this many times

-q

Quiet mode: report only failures

-t duration

Time tests out after this long

-v

Verbose mode: always report test log

-h

Show help

file File to use as a script

Macro definitions that can be overridden.

varnishd Path to varnishd to use [varnishd]

If TMPDIR is set in the environment, varnishtest creates temporary vtc.* directories for each test in $TMPDIR, otherwise in /tmp.

SCRIPTS

The script language used for Varnishtest is not a strictly defined language. The best reference for writing scripts is the varnishtest program itself. In the Varnish source code repository, under bin/varnishtest/tests/, all the regression tests for Varnish are kept.

An example:

varnishtest "#1029" server s1{
    rxreq
        expect req.url == "/bar" txresp - gzipbody{[bar]} rxreq expect req.url ==
    "/foo" txresp - body{<h1> FOO < esi : include src = "/bar" / > BARF</ h1>}} -
    start
        varnish v1 -
    vcl + backend{sub vcl_backend_response{set beresp.do_esi = true;
if (bereq.url == "/foo") {
    set beresp.ttl = 0s;
} else {
    set beresp.ttl = 10m;
}
}
}
- start
        client c1{
            txreq - url "/bar" - hdr "Accept-Encoding: gzip" rxresp gunzip expect resp.bodylen == 5 txreq - url "/foo" - hdr "Accept-Encoding: gzip" rxresp expect resp.bodylen == 21} -
    run

When run, the above script will simulate a server (s1) that expects two different requests. It will start a Varnish server (v1) and add the backend definition to the VCL specified (-vcl+backend). Finally it starts the c1-client, which is a single client sending two requests.
