world-readable directory is fine. However, there may be problems if the

message).

+ configs can be placed into it. A suitable file location is .../exim/test/trusted_configs
+ DISABLE_D_OPTION must not be used. If ALT_CONFIG_PREFIX is used, it

BREAKING OUT OF THE TEST SCRIPT
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.
1 difference found.
"test-stdout-munged" contains 16 lines; "stdout/1300" contains 18 lines.

This example was generated by running the test with a version of Exim
that had a bug in the exim_dbmbuild utility (the bug was fixed at release

default that is given in brackets (in this case Q), or a single letter, in

else, the prompt is repeated.
"Continue" carries on as if the files had matched; that is, it ignores the
"Update & retry" copies the new file to the saved file, and reruns the test
after doing any further comparisons that may be necessary.
+"Retry" does the same apart from the file copy.
+
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.

OTHER SCRIPTS AND PROGRAMS

The runtest script also makes use of a number of ordinary commands such as
"cp", "kill", "more", and "rm", via the system() call. In some cases these are
These commands are not followed by any input data, or by a line of asterisks.

This command runs the exim_dbmbuild utility to build a DBM file. It is used

echo <text>
The text is written to the screen; this is used to output comments from
scripts.

+This command runs the exigrep utility with the given data (the search pattern)
+on the current mainlog file.

gnutls
This command is present at the start of all but one of the tests that use
GnuTLS. It copies a pre-existing parameter file into the spool directory, so

Commands with input
This command runs the auxiliary "client" program that simulates an SMTP client.
It is controlled by a script read from its standard input, details of which are
-given below. The only option is -t, which must be followed by a number, to
-specify the command timeout in seconds. The program connects to the given IP
-address and port, using the specified interface, if one is given.
+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
+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.
client-ssl [<options>] <ip address> <port> [<outgoing interface>] \
When OpenSSL is available on the host, an alternative version of the client
program is compiled, one that supports TLS using OpenSSL. The additional
-arguments specify a certificate and key file when required. There is one
-additional option, -tls-on-connect, that causes the client to initiate TLS
-negotiation immediately on connection.

+filename argument, the CA info for verifying the stapled response.

input does not match, the server bombs out with an error message.

messages to port PORT_S on the local host. When it has finished, the test
script waits for the "server" process to finish.
+The "mtpscript" program is like "server", except that it uses stdin/stdout for
+its input and output instead of a script. However, it is not called from test
+scripts; instead it is used as the command for pipe transports in some
+configurations, to simulate non-socket LMTP servers.
