    This takes two strings as parameter, and evaluates the

    successful.  <message> should state what it is testing.

+
+   This works similar to test_expect_equal (see above) but is used to

+ test_debug <script>
 
    This takes a single argument, <script>, and evaluates it only
    when the test script is started with --debug command line
    argument.  This is primarily meant for use during the
    development of a new test script.

+
+   This function executes the provided emacs lisp script within

+
+ test_done
 
    Your test script must have test_done at the end.  Its purpose
    is to summarize successes and failures in the test script and
    exit with an appropriate error code.

+
+  add_message
+
+    Generate a message and add it to the database (by calling "notmuch
+    new"). It is sufficient to simply call add_message with no
+    arguments if you don't care about the content of the message. If
+    more control is needed, arguments can be provide to specify many
+    different header values for the new message. See the documentation
+    within test-lib.sh or refer to many example calls within existing
+    tests.
+
+  add_email_corpus
+
+    This function should be called at the beginning of a test file
+    when a test needs to operate on a non-empty body of messages. It
+    will initialize the mail database to a known state of 50 sample
+    messages, (culled from the early history of the notmuch mailing
+    list).
