VARNISHTEST(1) 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 in- stances 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, allow- ing 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 parame- ters 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" ...
