varnishtest: Test program for Varnish

NAME

varnishtest - Test program for Varnish

SYNOPSIS

varnishtest [-n iter] [-q] [-v] 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. The following options are available: -n iter Run iter number of iterations. -q Be quiet. -v Be verbose. -t Dunno. file File to use as a script

SCRIPTS

Example script # Start a varnish instance called "v1" varnish v1 -arg "-b localhost:9080" -start # Create a server thread called "s1" server s1 { # Receive a request rxreq # Send a standard response txresp -hdr "Connection: close" -body "012345\n" } # Start the server thread server s1 -start # Create a client thread called "c1" client c1 { # Send a request txreq -url "/" # Wait for a response rxresp # Insist that it be a success expect resp.status == 200 } # Run the client client c1 -run # Wait for the server to die server s1 -wait # (Forcefully) Stop the varnish instance. varnish v1 -stop Example script output The output, running this script looks as follows. The "bargraph" at the beginning of the line is an indication of the level of detail in the line. The second field where the message comes from. The rest of the line is anyones guess :-) # TEST tests/b00000.vtc starting ### v1 CMD: cd ../varnishd && ./varnishd -d -d -n v1 -a :9081 -T :9001 -b localhost:9080 ### v1 opening CLI connection #### v1 debug| NB: Storage size limited to 2GB on 32 bit architecture,\n #### v1 debug| NB: otherwise we could run out of address space.\n #### v1 debug| storage_file: filename: ./varnish.Shkoq5 (unlinked) size 2047 MB.\n ### v1 CLI connection fd = 3 #### v1 CLI TX| start #### v1 debug| Using old SHMFILE\n #### v1 debug| Notice: locking SHMFILE in core failed: Operation not permitted\n #### v1 debug| bind(): Address already in use\n #### v1 debug| rolling(1)... #### v1 debug| \n #### v1 debug| rolling(2)...\n #### v1 debug| Debugging mode, enter "start" to start child\n ### v1 CLI 200 <start> ## s1 Starting server ### s1 listen on :9080 (fd 6) ## c1 Starting client ## c1 Waiting for client ## s1 started on :9080 ## c1 started ### c1 connect to :9081 ### c1 connected to :9081 fd is 8 #### c1 | GET / HTTP/1.1\r\n #### c1 | \r\n ### c1 rxresp #### s1 Accepted socket 7 ### s1 rxreq #### s1 | GET / HTTP/1.1\r\n #### s1 | X-Varnish: 422080121\r\n #### s1 | X-Forwarded-For: 127.0.0.1\r\n #### s1 | Host: localhost\r\n #### s1 | \r\n #### s1 http[ 0] | GET #### s1 http[ 1] | / #### s1 http[ 2] | HTTP/1.1 #### s1 http[ 3] | X-Varnish: 422080121 #### s1 http[ 4] | X-Forwarded-For: 127.0.0.1 #### s1 http[ 5] | Host: localhost #### s1 | HTTP/1.1 200 Ok\r\n #### s1 | Connection: close\r\n #### s1 | \r\n #### s1 | 012345\n #### s1 | \r\n ## s1 ending #### c1 | HTTP/1.1 200 Ok\r\n #### c1 | Content-Length: 9\r\n #### c1 | Date: Mon, 16 Jun 2008 22:16:55 GMT\r\n #### c1 | X-Varnish: 422080121\r\n #### c1 | Age: 0\r\n #### c1 | Via: 1.1 varnish\r\n #### c1 | Connection: keep-alive\r\n #### c1 | \r\n #### c1 http[ 0] | HTTP/1.1 #### c1 http[ 1] | 200 #### c1 http[ 2] | Ok #### c1 http[ 3] | Content-Length: 9 #### c1 http[ 4] | Date: Mon, 16 Jun 2008 22:16:55 GMT #### c1 http[ 5] | X-Varnish: 422080121 #### c1 http[ 6] | Age: 0 #### c1 http[ 7] | Via: 1.1 varnish #### c1 http[ 8] | Connection: keep-alive #### c1 EXPECT resp.status (200) == 200 (200) match ## c1 ending ## s1 Waiting for server #### v1 CLI TX| stop ### v1 CLI 200 <stop> # TEST tests/b00000.vtc completed If instead of 200 we had expected 201 with the line:: expect resp.status == 201 The output would have ended with:: #### c1 http[ 0] | HTTP/1.1 #### c1 http[ 1] | 200 #### c1 http[ 2] | Ok #### c1 http[ 3] | Content-Length: 9 #### c1 http[ 4] | Date: Mon, 16 Jun 2008 22:26:35 GMT #### c1 http[ 5] | X-Varnish: 648043653 648043652 #### c1 http[ 6] | Age: 6 #### c1 http[ 7] | Via: 1.1 varnish #### c1 http[ 8] | Connection: keep-alive ---- c1 EXPECT resp.status (200) == 201 (201) failed
