 * KSP needs to be built with JDK 11+, because of some test dependencies.
 * Create a test processor under the sample processor folder.

 * Write your logic by overriding corresponding functions. 
     * Test is performed by running test processor and get a collection of test results in the form of List<String>.
     * Make sure you override toResult() function to collect test result. 
     * Leverage visitors for easy traverse of the test case.
     * To help with easy testing, you can create an annotation for test, and annotate the specific part of the code to avoid doing 
     excess filtering when traveling along the program.
 * Write your test case to work with test processor.
