Can you teach me how to test the "uuid" here?
Probably the best thing is to look at the tests for set_e2uuid:
tests =
(let uuid = uuidgen () in [
InitBasicFS, Always, TestOutput (
[["set_e2uuid"; "/dev/sda1"; uuid];
["get_e2uuid"; "/dev/sda1"]], uuid);
'tests = (let uuid = uuidgen () in [...])' causes a fresh uuid to be
generated (by 'uuidgen ()') and returned in 'uuid', and then
substituted in the list of tests. In this case, 'uuid' is used as a
parameter to 'set_e2uuid', and to test the return value from
'get_e2uuid'.
Note that the random UUID changes each time the generator runs.
The actual C code generated by the above test (ie. in
tests/c-api/tests.c) is below. In this case, the value of the 'uuid'
variable in the OCaml code was "d62333[..]".
/* TestOutput for set_e2uuid (0) */
const char *expected = "d623335b-b2c7-461c-46a8-05a4f2af7bee";
{
const char *device = "/dev/sda1";
const char *uuid = "d623335b-b2c7-461c-46a8-05a4f2af7bee";
int r;
suppress_error = 0;
r = guestfs_set_e2uuid (g, device, uuid);
if (r == -1)
return -1;
}
{
const char *device = "/dev/sda1";
char *r;
suppress_error = 0;
r = guestfs_get_e2uuid (g, device);
if (r == NULL)
return -1;
if (STRNEQ (r, expected)) {
fprintf (stderr, "test_set_e2uuid_0: expected \"%s\" but got
\"%s\"\n", expected, r);
return -1;
}
free (r);
}
