Hi Guoping,

To automate testing, you should check the expected output of the dominators analysis checker with FileCheck. Inside the test, you specify the command which should be applied on it as well as the expected output. It will get tested when you run the following from the clang build directory (see the Testing section on http://clang.llvm.org/hacking.html):
$ make test
or if you only want to test the tests from the analysis folder:
$ TESTDIRS=Analysis make test

Your test is probably going to look similar to the following example, which tests CFG builder:

You can find the documentation on FileCheck here: http://llvm.org/docs/TestingGuide.html The document might be a bit outdated but it does a good job explaining the concepts.
