I've made a try and quite satisfied by now.
https://github.com/ogbash/doxygen-tests

Currently there are only 8 tests, where 5 are taken from bug reports.
Release-1.7.1 gives 7 failures.
Release-1.7.3-20110217 gives 3 failures out of 8 tests.

runTest (tests.blocks.interface_abst_f90) ... ok
runTest (tests.blocks.interface_gen_f90) ... ok
runTest (tests.blocks.interface_op_f90) ... ok
runTest (tests.blocks.interface_spec_f90) ... ok
runTest (tests.syntax.label_endsub) ... ok
runTest (tests.linecont.parcomment_f) ... FAIL
runTest (tests.linecont.parcomment_f90) ... FAIL
runTest (tests.linecont.varcomment_f90) ... FAIL

89e2c4 from https://github.com/ogbash/doxygen-f90 gives no errors.

Writing tests is not trivial but managable after making yourself
familiar to XPath syntax.
For example, testing that 'example' subroutine exists in
'parcomment.f' file and its 'val' parameter is documented:

        file = self.getFile("parcomment.f")
        example = self.getSubprogram(file, "example")

        desc = self.getParamDescription(example, "val")
        self.assertEqual(desc.getContent().strip(), "[in] scalar double input")

Testing type of the variable 'as' with XPath:

        var = self.getModuleVariable(varcomment, "as")
        self.assertEqual(var.xpathEval("type")[0].getContent().strip(),
                         "integer, dimension(:,:), pointer")


Any suggestions, comments, or even new tests are welcome,
Oleg
