    1 xnu_quick_test - this tool will do a quick test of every (well, to be
    2 honest most) system calls we support in xnu.
    3 
    4 WARNING - this is not meant to be a full regression test of all the
    5 system calls.  The intent is to have a quick test of each system call that
    6 can be run very easily and quickly when a new kerenl is built.
    7 
    8 This tool is meant to grow as we find xnu problems that could have be
    9 caught before we submit to a build train.  So please add more tests and
   10 make the existing ones better.  Some of the original tests are nothing
   11 more than place holders and quite lame.  Just keep in mind that the tool
   12 should run as fast as possible.  If it gets too slow then most people
   13 will stop running it.
   14 
   15 LP64 testing tip - when adding or modifying tests, keep in mind the
   16 variants in the LP64 world.  If xnu gets passed a structure the varies in
   17 size between 32 and 64-bit processes, try to test that a field in the 
   18 sructure contains valid data.  For example if we know foo structure
   19 looks like:
   20 struct foo {
   21              int             an_int;
   22              long    a_long;
   23              int             another_int;
   24 }
   25 And if we know what another_int should contain then test for the known
   26 value since it's offset will vary depending on whether the calling process
   27 is 32 or 64 bits.
   28 
   29 NOTE - we have several workarounds and test exceptions for some
   30 outstanding bugs in xnu.  All the workarounds are marked with "todo" and
   31 some comments noting the radar number of the offending bug.  Do a seach
   32 for "todo" in the source files for this project to locate which tests have
   33 known failures.   And please tag any new exceptions you find with "todo"
   34 in the comment and the radar number of the bug.
   35 
   36 To build a fat binary, export ARCH="ppc ppc64 i386 x86_64". This will work
   37 for any architectures that Apple gcc recognizes.
   38 
   39 Added three defines which you can use at the compile line to build variants.
   40 DEBUG
   41        turn on additional printfs
   42 CONFORMANCE_TESTS_IN_XNU 
   43        when conformance tests are in xnu, set this to 1
   44 TEST_SYSTEM_CALLS
   45        test system calls (doesn't compile; a different bug)
   46 by default, all three are set to 0, i.e. disabled.  To build, export
   47 MORECFLAGS with the values you want set, e.g. 
   48        export MORECFLAGS="-D DEBUG=1 -D CONFORMANCE_TESTS_IN_XNU=1"
   49 
   50 todo:
   51 -- have folks with area expertise fix lame tests
   52    (most of the networking related tests are pretty lame)
   53 -- mach system calls support
   54 
   55 
   56 USAGE:  xnu_quick_test -target TARGET_PATH 
   57 
   58          -f[ailures] MAX_FAILS_ALLOWED   # number of test cases that may fail before we give up.  defaults to 0  
   59          -l[ist]                         # list all the tests this tool performs   
   60          -r[un] 1, 3, 10 - 19            # run specific tests.  enter individual test numbers and/or range of numbers.  use -list to list tests.   
   61          -s[kip]                         # skip setuid tests   
   62          -t[arget] TARGET_PATH           # path to directory where tool will create test files.  defaults to "/tmp/"   
   63 
   64 examples:  
   65 --- Place all test files and directories at the root of volume "test_vol" --- 
   66 xnu_quick_test -t /Volumes/test_vol/ 
   67  
   68 --- Run the tool for tests 10 thru 15, test 18 and test 20 --- 
   69 xnu_quick_test -r 10-15, 18, 20 
   70
