VARNISHTEST(1)              General Commands Manual             VARNISHTEST(1)

NAME
       varnishtest - Test program for Varnish

SYNOPSIS
       varnishtest [-hikLlqv] [-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     Set PATH and vmod_path to find varnish binaries 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

       -p name=val      Pass parameters to all varnishd command lines

       -q     Quiet mode: report only failures

       -t duration
              Time tests out after this long (default: 60s)

       -v     Verbose mode: always report test log

       file             File to use as a script

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

SCRIPTS
       The vtc syntax is documented at length in vtc(7). Should you want more
       examples than the one below, you can have a look at the Varnish source
       code repository, under bin/varnishtest/tests/, where 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.

TESTING A BUILD TREE
       Whether you are building a VMOD or trying to use one that you freshly
       built, you can tell varnishtest to pass a vmod_path to varnishd
       instances started using the varnish -start command in your test case:

          varnishtest -p vmod_path=... /path/to/*.vtc

       This way you can use the same test cases on both installed and built
       VMODs:

          server s1 {...} -start

          varnish v1 -vcl+backend {
              import wossname;

              ...
          } -start

          ...

       You are not limited to the vmod_path and can pass any parameter,
       allowing you to run a build matrix without changing the test suite. You
       can achieve the same with macros, but then they need to be defined on
       each run.

       You can see the actual varnishd command lines in test outputs, they
       look roughly like this:

          exec varnishd [varnishtest -p params] [testing params] [vtc -arg params]

       Parameters you define with varnishtest -p may be overridden by
       parameters needed by varnishtest to run properly, and they may in turn
       be overridden by parameters set in test scripts.

       There's also a special mode in which varnishtest builds itself a PATH
       and a vmod_path in order to find Varnish binaries (programs and VMODs)
       in the build tree surrounding the varnishtest binary. This is meant for
       testing of Varnish under development and will disregard your vmod_path
       if you set one.

       If you need to test your VMOD against a Varnish build tree, you must
       install it first, in a temp directory for instance. With information
       provided by the installation's pkg-config(1) you can build a proper
       PATH in order to access Varnish programs, and a vmod_path to access
       both your VMOD and the built-in VMODs:

          export PKG_CONFIG_PATH=/path/to/install/lib/pkgconfig

          BINDIR="$(pkg-config --variable=bindir varnishapi)"
          SBINDIR="$(pkg-config --variable=sbindir varnishapi)"
          PATH="SBINDIR:BINDIR:$PATH"

          VMODDIR="$(pkg-config --variable=vmoddir varnishapi)"
          VMOD_PATH="/path/to/your/vmod/build/dir:$VMODDIR"

          varnishtest -p vmod_path="$VMOD_PATH" ...
