No, test merge only checks that the items are where you think they are
in the repository and shows where there might be conflicts. Since
merge tracking arrived it has become almost impossible to discover
whether conflicts will actually occur without doing a real merge. In
theory it would be possible to create a copy of the working copy and
do a dummy run there, but since many people have GB working copies
this is not a quick option.

No, for the same reasons as above.

Isn't that what the Check for Modifications dialog does? And diff with URL?
