Test program for Varnish¶

SYNOPSIS¶
varnishtest [-hikLlqvW] [-b size] [-D name=val] [-j jobs] [-n iter] [-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:
- -b size
Set internal buffer size (default: 1M)
-D name=val Define macro for use in scripts
- -h
Show help
- -i
Find varnishd in build tree
- -j jobs
Run this many tests in parallel
- -k
Continue on test failure
- -L
Always leave temporary vtc.*
- -l
Leave temporary vtc.* if test fails
- -n iterations
Run tests this many times
- -q
Quiet mode: report only failures
- -t duration
Time tests out after this long (default: 60s)
- -v
Verbose mode: always report test log
- -W
Enable the witness facility for locking
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.
