Johnny Chen 707b3c9c73 Added the capability for the test driver to relocate the tests and the intermediate
files to a different top level directory than those specified on the command line.

When relocated, the test clanups normally performed afterwards after each test method
and after each test class will not be exercised at all.  This allows for an easier
postmortem analysis of test failures.

Example:

./dotest.py -v -t -r /tmp/lldbtest types

will create a /tmp/lldbtest directory which houses the types directory and its supported
files.

Files modified:

o dotest.py, lldbtest.py:

  Add logic to process '-r dir' option to support relocating the tests to a different
  top level directory instead of exected in place.

o darwin.py, test/types/Makefile:

  The 'make clean' should only clean the minimum .o and .d files.

Johnny Chen 0ed37c9615 o SBtarget.cpp/.h:
Temporarily commenting out the deprecated LaunchProcess() method.
  SWIG is not able to handle the overloaded functions.

o dotest.py/lldbtest.py:

  Add an '-w' option to insert some wait time between consecutive test cases.

o TestClassTypes.py:

  Make the breakpoint_creation_by_filespec_python() test method more robust and
  more descriptive by printing out a more insightful assert message.

o lldb.swig: Coaches swig to treat StateType as an int type, instead of a C++ class.

Johnny Chen 56e6cbdaf0 Enhance the test driver with a '-f filterspec' option to specify the
testclass.testmethod to be run and with a '-g' option which instructs the test
driver to only admit the module which satisfy the filterspec condition to the
test suite.

Example:

# This only runs the test case under the array_types directory which has class
# name of 'ArrayTypesTestCase' and the test method name of 'test_with_dwarf_and_run_command'.

/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v -f 'ArrayTypesTestCase.test_with_dwarf_and_run_command' -g array_types
----------------------------------------------------------------------
Collected 1 test

test_with_dwarf_and_run_command (TestArrayTypes.ArrayTypesTestCase)
Test 'frame variable var_name' on some variables with array types. ... ok

----------------------------------------------------------------------
Ran 1 test in 1.353s

OK

# And this runs the test cases under the array_types and the hello_world directories.
# If the module discovered has the 'ArrayTypesTestCase.test_with_dwarf_and_run_command'
# attribute, only the test case specified by the filterspec for the module will be run.
# If the module does not have the said attribute, e.g., the module under hello_world,
# the whole module is still admitted to the test suite.

/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v -f 'ArrayTypesTestCase.test_with_dwarf_and_run_command' array_types hello_world

Johnny Chen da88434b39 o Added a new feature to the test framework to skip long running tests conditionally.
To not skip long running tests, pass '-l' to the test driver (dotest.py).

  An example:

    @unittest2.skipIf(TestBase.skipLongRunningTest(), "Skip this long running test")
    def test_foundation_disasm(self):
        ...

o Added a long running disassemble test to the foundation directory, which iterates
  the code symbols from Foundation.framework and kicks off a disassemble command for
  for the named function symbol.  Found a crasher: rdar://problem/8504895.

o Plus added/updated some comments for the TestBase class.

Johnny Chen 6316021bae Added "float" and "double" to types/TestBasicTypes.py. Abstracted the generic
type tester method into its own abstarct base class 'AbstractBase'.  And
added TestIntegerTypes.py and TestFloatTypes.py.

Added an option "-p reg-exp-pattern" to the test driver to specify a regular
expression pattern to match against eligible filenames as our test cases.

An example: 

/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v -p "TestFloat.*" types
----------------------------------------------------------------------

Johnny Chen 209cdbef64 Added the capability to source the configFile specified via the "-c" option in
order to customize the running of the test suite.  For the time being, the
supported customizations are:

o redirecting stdout and/or stderr
o specifying a list of compilers to build the test programs
o specifying a list of architectures to build the test programs for

Also checked into the examples/test directory some example files which
demonstrate the usage for the above customizations.

$ ./dotest.py -v -c ~/.lldbtest-config persistent_variables
$ cat ~/.lldbtest-config
sys.stderr = open("/tmp/lldbtest-stderr", "w")
sys.stdout = open("/tmp/lldbtest-stdout", "w")

Johnny Chen 49b415de1f Added a hook for the test driver to take an optional config file to customize
the running of the test suite.  Right now, it doesn't do anything with the
config file.

Pass "-c myConfigFile" to specify the config file.

Johnny Chen df80a4cf25 Cleaned up the option processing logic and added a '-i' option to ignore the
build tree relative search path in order to locate the lldb.py module.  When
'-i' is present, the test driver relies on the PYTHONPATH environment variable
to locate the lldb.py module.

2010-09-16 15:44:23 +00:00
Johnny Chen 73982b94e3 Also added BuildAndIntegration to the directories to search for an existing
lldb.py module.  The priorities to search for are Debug, Release, then
BuildAndIntegration.  You can always override this with a valid PYTHONPATH
environment variable before running the test driver.

For example:

$ PYTHONPATH=/Find/My/LLDB/Module/Here ./dotest.py -v .

Python runtime will try to locate the lldb.py module from
/Find/My/LLDB/Module/Here first before trying the Debug, Release, and then
BuildAndIntegration directories.

Johnny Chen 1aad5c61f8 Removed the expectedFailure decorator from test_with_dwarf_and_run_command() test case
as it now passes.  Added some extra tests to breakpoint_creation_by_filespec_python().

More clarification for the "os command" output and error as defined in
lldbtest.system() function.

Cleaned up the option processing of the test driver (dotest.py) and fixed the comment
about enabling gdb-remote logging.  Example:

$ GDB_REMOTE_LOG=/tmp/log.txt ./dotest.py -v -t enum_types

Johnny Chen 8d55a34a34 Changed the buildDsym()/buildDwarf() TestBase methods to use a plugin framework
to delegate the building of binaries to a sys.platform-sepcific plugin.

Modified the dotest.py test driver to add the "plugins" directory to the
PYTHONPATH as well.

darwin.py is the Mac OS X plugin module.

Johnny Chen d0190a6182 Changed the keyword argument for runCmd()/expect() from 'verbose' to 'trace',
which, defaults to False, and if set to True, will trace lldb command execution
and result.

Added "-t" command option to the test driver dotest.py which sets the
LLDB_COMMAND_TRACE environment variable to "YES" and as a result always turns on
command tracing regardless of the 'trace' keyword argument to runCmd()/expect().

  skipping tests and expected failures.

  TestSTL.test_step_into_stl(), which is known to always fail currently, with
  @unittest2.expectedFailure.

PYTHONPATH component for locating the lldbtest module, which sits in the same
directory.

Johnny Chen a765c28db3 A simple testing framework for lldb using python's unit testing framework.
Tests for lldb are written as python scripts which take advantage of the script
bridging provided by LLDB.framework to interact with lldb core.

A specific naming pattern is followed by the .py script to be recognized as
a module which implements a test scenario, namely, Test*.py.

To specify the directories where "Test*.py" python test scripts are located,
you need to pass in a list of directory names.  By default, the current
working directory is searched if nothing is specified on the command line.

An example:

[14:10:20] johnny:/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v example
test_choice (TestSequenceFunctions.TestSequenceFunctions) ... ok
test_sample (TestSequenceFunctions.TestSequenceFunctions) ... ok
test_shuffle (TestSequenceFunctions.TestSequenceFunctions) ... ok
