message).

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.

"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.

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
