| HAProxy regression testing with vtest |

+---------------------------------------+

The information found in this file are a short starting guide to help you to

write VTC (Varnish Test Case) scripts (or VTC files) for haproxy regression testing.

Such VTC files are currently used to test Varnish cache application developed by

Poul-Henning Kamp. A very big thanks you to him for having helped you to add

our haproxy C modules to vtest tool. Note that vtest was formally developed for

varnish cache reg testing and was named varnishtest. vtest is an haproxy specific

version of varnishtest program which reuses the non varnish cache specific code.

A lot of general information about how to write VTC files may be found in 'man/vtc.7'

manual of varnish cache sources directory or directly on the web here:

https://varnish-cache.org/docs/trunk/reference/vtc.html

It is *highly* recommended to read this manual before asking to haproxy ML. This

documentation only deals with the vtest support for haproxy.

vtest installation

------------------------

To use vtest you will have to download and compile the recent vtest

sources found at https://github.com/vtest/VTest.

To compile vtest:

$ cd VTest

$ make vtest

Note that varnishtest may be also compiled but not without the varnish cache

sources already compiled:

$ VARNISH_SRC=<...> make varnishtest

After having compiled these sources, the vtest executable location is at the

root of the vtest sources directory.

vtest execution

---------------------

vtest is able to search for the haproxy executable file it is supposed to

launch thanks to the PATH environment variable. To force the executable to be used by

vtest, the HAPROXY_PROGRAM environment variable for vtest may be

typically set as follows:

$ HAPROXY_PROGRAM=~/srcs/haproxy/haproxy vtest ...

vtest program comes with interesting options. The most interesting are:

-t Timeout in seconds to abort the test if some launched program

-v By default, vtest does not dump the outputs of process it launched

when the test passes. With this option the outputs are dumped even

when the test passes.

-L to always keep the temporary VTC directories.

-l to keep the temporary VTC directories only when the test fails.

About haproxy, when launched by vtest, -d option is enabled by default.

How to write VTC files

----------------------

A VTC file must start with a "varnishtest" or "vtest" command line followed by a

descriptive line enclosed by double quotes. This is not specific to the VTC files

for haproxy.

The VTC files for haproxy must also contain a "feature ignore_unknown_macro" line

if any macro is used for haproxy in this file. This is due to the fact that

vtest parser code for haproxy commands generates macros the vtest

parser code for varnish cache has no knowledge of. This line prevents vtest from

failing in such cases. As a "cli" macro automatically generated, this

"feature ignore_unknown_macro" is mandatory for each VTC file for haproxy.

To make vtest capable of testing haproxy, two new VTC commands have been

implemented: "haproxy" and "syslog". "haproxy" is used to start haproxy process.

"syslog" is used to start syslog servers (at this time, only used by haproxy).

As haproxy cannot work without configuration file, a VTC file for haproxy must

embed the configuration files contents for the haproxy instances it declares.

This may be done using the following intuitive syntax construction: -conf {...}.

Here -conf is an argument of "haproxy" VTC command to declare the configuration

file of the haproxy instances it also declares (see "Basic HAProxy test" VTC file

below).

As for varnish VTC files, the parser of VTC files for haproxy automatically

generates macros for the declared frontends to be reused by the clients later

in the script, so after having written the "haproxy" command sections.

The syntax "fd@${my_frontend_fd_name}" must be used to bind the frontend

listeners to localhost address and random ports (see "Environment variables"

section of haproxy documentation). This is mandatory.

Each time the haproxy command parser finds a "fd@${xyz}" string in a 'ABC'

"haproxy" command section, it generates three macros: 'ABC_xyz_addr', 'ABC_xyz_port'

and 'ABC_xyz_sock', with 'ABC_xyz_sock' being resolved as 'ABC_xyz_addr

ABC_xyz_port' typically used by clients -connect parameter.

Each haproxy instance works in their own temporary working directories located

at '/tmp/vtc.<varnitest PID>.XXXXXXXX/<haproxy_instance_name>' (with XXXXXXXX

a random 8 digits hexadecimal integer. This is in this temporary directory that

the configuration file is temporarily written.

A 'stats.sock' UNIX socket is also created in this directory. There is no need

to declare such stats sockets in the -conf {...} section. The name of the parent

directory of the haproxy instances working directories is stored in 'tmpdir'. In

fact this is the working directory of the current vtest process.

There also exists 'testdir' macro which is the parent directory of the VTC file.

It may be useful to use other files located in the same directory than the current

VTC file.

VTC file examples

-----------------

The following first VTC file is a real regression test case file for a bug which has

been fixed by 84c844e commit. We declare a basic configuration for a 'h1' haproxy

instance.

-conf-BAD haproxy command argument is used. Its role it to launch haproxy with

-c option (configuration file checking) and check that 'h1' exit(3) with 1 as

status. Here is the output when running this VTC file:

The following VTC file does almost nothing except running a shell to list

the contents of 'tmpdir' directory after having launched a haproxy instance

and 's1' HTTP server. This shell also prints the content of 'cfg' 'h1' configuration

file.

The following example illustrate how to run a basic HTTP transaction between 'c1'

client and 's1' server with 'http1' as haproxy frontend. This frontend listen

on TCP socket with 'my_frontend_fd' as file descriptor.

# Mandatory line

varnishtest "Basic HAProxy test"

# As some macros for haproxy are used in this file, this line is mandatory.

feature ignore_unknown_macro

server s1 {

rxreq

txresp -body "s1 >>> Hello world!"

} -start

haproxy h1 -conf {

# Configuration file of 'h1' haproxy instance.

defaults

mode http

timeout connect 5s

timeout server 30s

timeout client 30s

backend be1

# declare 'srv1' server to point to 's1' server instance declare above.

server srv1 ${s1_addr}:${s1_port}

frontend http1

use_backend be1

bind "fd@${my_frontend_fd}"

} -start

client c1 -connect ${h1_my_frontend_fd_sock} {

txreq -url "/"

rxresp

expect resp.status == 200

expect resp.body == "s1 >>> Hello world!"

} -run

It is possible to shorten the previous VTC file haproxy command section as follows:

haproxy h1 -conf {

# Configuration file of 'h1' haproxy instance.

defaults

mode http

timeout connect 5s

timeout server 30s

timeout client 30s

}

In this latter example, "backend" and "frontend" sections are automatically

generated depending on the declarations of server instances.

Another interesting real regression test case is the following: we declare one

server 's1', a syslog server 'Slg_1' and a basic haproxy configuration for 'h1'

haproxy instance. Here we want to check that the syslog message are correctly

formatted thanks to "expect" "syslog" command (see syslog Slg_1 {...} command)

below.

#commit d02286d6c866e5c0a7eb6fbb127fa57f3becaf16

# BUG/MINOR: log: pin the front connection when front ip/ports are logged

#

# Mathias Weiersmueller reported an interesting issue with logs which Lukas

# diagnosed as dating back from commit 9b061e332 (1.5-dev9). When front

# connection information (ip, port) are logged in TCP mode and the log is

# emitted at the end of the connection (eg: because %B or any log tag

# requiring LW_BYTES is set), the log is emitted after the connection is

# closed, so the address and ports cannot be retrieved anymore.

#

# It could be argued that we'd make a special case of these to immediately

# retrieve the source and destination addresses from the connection, but it

# seems cleaner to simply pin the front connection, marking it "tracked" by

# adding the LW_XPRT flag to mention that we'll need some of these elements

# at the last moment. Only LW_FRTIP and LW_CLIP are affected. Note that after

# this change, LW_FRTIP could simply be removed as it's not used anywhere.

# Note that the problem doesn't happen when using %[src] or %[dst] since

# all sample expressions set LW_XPRT.

This test does not pass without the bug fix of d02286d commit. Indeed the third syslog

message received by 'Slg_1' syslog server does not match the regular expression

of the "syslog" "expect" command:

expect ~ \"dip\":\"${h1_fe_1_addr}\",\"dport\":\"${h1_fe_1_port}.*\"ts\":\"cD\",\"

(the IP address and port are missing), contrary to what happens with the correct bug fix:
