1 ;also do this: make two frames, one viewing "*scratch*", the other "foo".
2 ;in *scratch*, type (sit-for 20)^J
3 ;wait a couple of seconds, move cursor to foo, type "a"
4 ;a should be inserted in foo. Cursor highlighting should not change in
7 ;do it with sleep-for. move cursor into foo, then back into *scratch*
9 ;repeat also with (accept-process-output nil 20)
11 ;make sure ^G aborts sit-for, sleep-for and accept-process-output:
14 (list (condition-case c
19 (tst)^Ja^G ==> ((quit) 97) with no signal
20 (tst)^J^Ga ==> ((quit) 97) with no signal
21 (tst)^Jabc^G ==> ((quit) 97) with no signal, and "bc" inserted in buffer
23 ; with sit-for only do the 2nd test.
24 ; Do all 3 tests with (accept-proccess-output nil 20)
27 Additional test cases for accept-process-output, sleep-for, sit-for.
28 Be sure you do all of the above checking for C-g and focus, too!
30 ; Make sure that timer handlers are run during, not after sit-for:
32 (add-timeout 2 '(lambda (ignore) (message "timer ran")) nil)
34 (message "after sit-for"))
36 ; The first message should appear after 2 seconds, and the final message
37 ; 3 seconds after that.
38 ; repeat above test with (sleep-for 5) and (accept-process-output nil 5)
40 ; Make sure that process filters are run during, not after sit-for.
42 (message "sit-for = %s" (sit-for 30)))
43 (add-hook 'post-command-hook 'fubar)
45 ; Now type M-x shell RET
46 ; wait for the shell prompt then send: ls RET
47 ; the output of ls should fill immediately, and not wait 30 seconds.
49 ; repeat above test with (sleep-for 30) and (accept-process-output nil 30)
53 ; Make sure that recursive invocations return immediately:
54 (defmacro test-diff-time (start end)
55 `(+ (* (- (car ,end) (car ,start)) 65536.0)
56 (- (cadr ,end) (cadr ,start))
57 (/ (- (caddr ,end) (caddr ,start)) 1000000.0)))
59 (defun testee (ignore)
63 (let ((start (current-time))
65 (add-timeout 2 'testee nil)
67 (add-timeout 2 'testee nil)
69 (add-timeout 2 'testee nil)
70 (accept-process-output nil 5)
71 (setq end (current-time))

74 (test-them) should sit for 15 seconds.
