how could I execute a set of script in a directoy tree?

[龙海涛]

i have a directory, like this

/testcase
    /syntaxcheck
        /test1
            0                             (common txt file)
            0.expected             (common txt file)
            1
            1.expected
            ...
            autotest.sh             (shell script)
        /test2
            0
            0.expected
            1
            1.expected
            ...
            autotest.sh
        /test3
        ...
        /testn
    /semantic
        /test1
            0
            0.expected
            1
            1.expected
            ...
            autotest.sh
        /test2
        ...
        /testn
    ...
there are many autotest.sh in every leaf-directory(that is, no
sub-directory in this directory. e.g, testcase/syntaxcheck/test1).
when i want to execute a auototest.sh, i just came into a
leaf-directory,
and enter './autotest.sh' command, and all the testcases in this
leaf-directory will be examined.

but now what i want to do is write a shell script , call all the
autotest.sh in every leaf-directory.

is it possible or ridiculous?
