(5) Run "./runtest" (a Perl script) as described below.
------------------
If you do not supply any arguments to ./runtest, it searches for an Exim
-source tree at the same level as the test suite directory. It then looks for an
-Exim binary in a "build" directory of that source tree. If there are several
-Exim source trees, it chooses the latest version of Exim. Consider the
-following example:
+source tree at the same level as the test suite directory. A source tree

+
+It then looks for an Exim binary in a "build" directory of that source
+tree. If there are several Exim source trees, it chooses the latest
+version of Exim. Consider the following example:
$ ls -F /source/exim
exim-4.60/ exim-4.62/ exim-testsuite-x.xx/
There are some options for the ./runtest script itself:
+ -CONTINUE This will allow the script to move past some failing tests. It will
+ write a simple failure line with the test number in a temporary
+ logfile test/failed-summary.log. Unexpected exit codes will still
+ stall the test execution and require interaction.
+
-DEBUG This option is for debugging the test script. It causes some
tracing information to be output.
(If it turns out that most people prefer to use diff, I'll change
the default.)
+ -FLAVOR <flavor>
+ -FLAVOUR <flavour>
+ This allows "overrides" for the test results. It's intended
+ use is to deal with distro specific differences in the test
+ output. The default flavour is "FOO" if autodetection fails.
+ (Autodetection is possible for known flavours only. Known
+ flavours are computed after file name extensions in stdout/*
+ and stderr/*.)
+
+ If during the test run differences between the current and
+ the expected output are found and no flavour file exists already,
+ you may update the "common" expected output or you may create a
+ flavour file. If a flavour file already exists, any updates will go
+ into that flavour file!
+
-KEEP Normally, after a successful run, the test output files are
deleted. This option prevents this. It is useful when running a
single test, in order to look at the actual output before it is
Other circumstances give rise to other prompts. If a test generates output for
which there is no saved data, the prompt (after a message stating which file is
-unexpectely not empty) is:

. Test 0142 tests open file descriptors; on some hosts the output may vary.
+. Some tests may fail, for example 0022, because it says it uses cached data
+ when the expected output thinks it should not be in cache. Item #5 in the
+ Requirements section has:
+ "Exim must be built with its user and group specified at build time"
+ This means that you cannot use the "ref:username" in your Local/Makefile
+ when building the exim binary, in any of the following fields:
+ EXIM_USER EXIM_GROUP CONFIGURE_OWNER CONFIGURE_GROUP
+
+. If the runtest script warns that the hostname is not a Fully Qualified
+ Domain Name (FQDN), expect that some tests will fail, for example 0036,
+ with an extra log line saying the hostname doesn't resolve. You must use a
+ FQDN for the hostname for proper test functionality.
+
+. If you change your hostname to a FQDN, you must delete the test/dnszones
+ subdirectory. When you next run the runtest script, it will rebuild the
+ content to use the new hostname.
+
+. If your hostname has an uppercase characters in it, expect that some tests
+ will fail, for example, 0036, because some log lines will have the hostname
+ in all lowercase. The regex which extracts the hostname from the log lines
+ will not match the lowercased version.
+
+. Some tests may fail, for example 0015, with a cryptic error message:
+ Server return code 99
+ Due to security concerns, some specific files MUST have the group write bit
+ off. For the purposes of the test suite, some test/aux-fixed/* files MUST
+ have the group write bit off, so it's easier to just remove the group write
+ bit for all of them. If your umask is set to 002, the group write bit will
+ be on by default and you'll see this problem, so make sure your umask is
+ 022 and re-checkout the test/ subdirectory.
+
+. Some tests will fail if the username and group name are different. It does
+ not have to be the primary group, a secondary group is sufficient.

This command operates like the "write" command, which is described below,
It is controlled by a script read from its standard input, details of which are
given below. There are two options. One is -t, which must be followed directly
by a number, to specify the command timeout in seconds (e.g. -t5). The default
-timeout is 1 second. The other option is -tls-on-connect, which causes the
+timeout is 5 seconds. The other option is -tls-on-connect, which causes the
client to try to start up a TLS session as soon as it has connected, without
using the STARTTLS command. The client program connects to the given IP address
and port, using the specified interface, if one is given.
When OpenSSL is available on the host, an alternative version of the client
program is compiled, one that supports TLS using OpenSSL. The additional

+There are two additional options: -tls-on-connect, that causes the client to

Finally, "exim" can be preceded by "sudo", to run Exim as root. If more than
one of these prefixes is present, they must be in the above order.
+If the options include "-DSERVER" but not "-DNOTDAEMON", the script waits for
+Exim to start but then continues without waiting for it to terminate. Typically
+this will be for a daemon-mode "-bd" operation. The daemon should be later
+terminated using "killdaemon".

+ Any sequences of \x followed by two hex digits are converted to the equvalent
+ byte value. Any other character following a \ is sent verbatim.

idea is that there should not be any need to rely on an external DNS.
-The domain names that are handled directly by Exim, without being passed to

+The fakens program handles some names programmatically rather than using the
+fake zone files. These are:

test.again.dns This always provokes a TRY_AGAIN response, for testing the
handling of temporary DNS error. If the full domain name
test.fail.dns This always provokes a NO_RECOVERY response, for testing
DNS server failures.
-This special handling could now be done in the fakens program, but while the
-old test suite is still being used it has to be done in Exim itself, so for the
-moment it remains there.
-
The use of gethostbyname() and its IPv6 friends is also subverted when Exim is
running in the test harness. The test code handles a few special names
directly; for all the others it uses DNS lookups, which are then handled as
just described. Thus, the use of /etc/hosts is completely bypassed. The names
that are specially handled are:
- manyhome.test.ex This name is used for testing hosts with ridiculously large
- numbers of IP addresses; 2048 IP addresses are generated
- and returned. Doing it this way saves having to make the
- interface to fakens handle more records that can fit in the
- data block. The addresses that are generated are in the
- 10.250.0.0/16 network.
-
localhost Always returns 127.0.0.1 or ::1, for IPv4 and IPv6 lookups,
respectively.
