Programming Assignment 2 Grading:
--------------------------------------------------------------------------------
First, create a grading directory (e.g., in your private CS directory) and
copy the testAll script to your grading directory.
You may need to run the command: chmod a+x testAll
to make it executable.

For each student:
1) Create a subdirectory for that student within your grading directory, e.g.,
       mkdir Student_Annie
2) Download the student's submission from the Learn@UW Program 2 dropbox into
   the student subdirectory
3) Go into the subdirectory and unzip the file
       cd Student_Annie
       unzip Program*.zip
4) From your grading directory, run the testAll script giving it the name of
   the student's subdirectory
       testAll Student_Annie

   This will do the following:
   - create a JAVA/ subdirectory inside the student's directory containing 
     appropriately renamed source code files from which to run the tests
   - compile and run tests, displaying some info about compiling to the
     console and saving results from running tests to a file
   - the LinkedLoopTester is used to test the student's LinkedLoop (and 
     EmptyLoopException, and LinkedLoopIterator) with our DblListnode
     The test files it uses (with corresponding output) in the LoopTestFiles/ 
	 folder:
        loopOne.txt
        loopSmall.txt
        loopLarge.txt	 
   - the student's program is tested using the files below (if the student's
     LinkedLoop has errors in it, you may need to edit their MessageLoopEditor
	 so that it uses the ArrayListLoop instead of the students LinkedLoop)
     The test files it uses (with corresponding output) in the 
	 MessageLoopEditorTestFiles/ folder:
        badInput.txt
        emptyTest.txt
        cutCopyPaste.txt
        jumpPrevNext.txt
        addInsert.txt
        findTest.txt
        replaceTest.txt
	
6) Look at the file 'student.all.txt' to see where the student's output
   differed from ours. If the student got all the expected output, this 
   file will look like the file 
   /p/course/cs367-hasti/public/html/assignments/p2/grading/sample.all.txt

7) Make sure to look at the student's code as well (for style and 
   documentation, among other reasons).  Make sure to verify that the student
   implemented the LinkedLoop class using a circular doubly-linked list.
   
   Note that the default Eclipse tab stop is 4 spaces and many Linux utilities, 
   like less or more, use 8 spaces as their default.  Since students in this 
   367 aren't expected to know Linux, they really don't have any reason to 
   think that we'd be looking at their code with tab stops set at something 
   other than Eclipse's default.  So, make sure that you look at their code 
   with (Eclipses's default) 4-character tab stops (rather than expect them 
   to do something like configure Eclipse to either show tabs as 4-characters 
   or replace tabs with 4 spaces).  If you are using less to look at a file via
   Linux, you can set the tab stop with the -x flag, e.g.,

       less -x4 HelloWorld.java

   will display using 4 spaces for tabs.


Additional scripts:

testLoop
- give the name of the student directory as an argument 
  (e.g., testLoop Student_Annie)
- assumes that testAll has already been run (so the JAVA subdirectory contains
  all the source code)
- runs just the LoopTester stuff
- creates file named student.loop.txt

testMsg
- give the name of the student directory as an argument 
  (e.g., testMsg Student_Annie)
- assumes that testAll has already been run (so the JAVA subdirectory contains
  all the source code)
- runs just the MessageLoopTester stuff
- creates file name student.msg.txt

Note: if testAll doesn't terminate:
- kill it (ctrl-C)
- run testLoop
- run testMsg (and then testMsgForce if necessary)

If you have to terminate testLoop or testMsg, you can run each individual test 
from the directory you are grading in:
- If the student's code already compiled, it should be in the directory so you 
  can just run it.
- Copy the LoopTestFiles directory and the MessageLoopEditorTestFiles directory 
  to your grading directory.
- To test MessageLoopEditor, you can do, for example,
  java MessageLoopEditor MessageLoopEditorTestFiles/addBeforeAfter.txt > output.txt
  You can then compare the student's results with the expected results:
  diff -b  output.txt MessagLoopEditorTestFiles/addBeforeAfter.output.f.txt


Comments to add to student's gradesheet (as an overall comment):
	Good job!

Note: for each top-level part (like the EmptyLoopException class) that a 
student gets completely correct, make sure to add the comment:
	Good job!
so the student's gradefile contains some feedback for that part

Style and documentation:
Comments:
	Good commenting!
	Good coding style!
