Johnny Chen 04d2c5cb0e Modify the test driver and lldbtest.TestBase so that the dumping of session info
now goes into a timestamp-specific directory instead of the previous .session-*
files.

Also, the dumping happens when a test errored in additioned to when it failed.

Johnny Chen 24d6ea25f8 Missed this spot where module.cleanup() can be passed a test instance to
facilitate session recording.  This happens inside an instance method where the
test instance is well known.

Johnny Chen 690fcef762 Some re-achitecturing of the plugins interface. The caller is now required to
pass in a 'sender' arg to the buildDefault(), buildDsym(), buildDwarf(), and
cleanup() functions.  The sender arg will be the test instance itself (i.e.,
an instance of TestBase).  This is so that the relevant command execution can be
recorded in the TestBase.session object if sender is available.

The lldbtest.system() command has been modified to pop the 'sender' arg out of
the keyword arguments dictionary and use it as the test instance to facilitate
seesion recordings.  An example is in test/types/AbstractBase.py:

    def generic_type_tester(self, atoms, quotedDisplay=False):
        """Test that variables with basic types are displayed correctly."""

        # First, capture the golden output emitted by the oracle, i.e., the
        # series of printf statements.
        go = system("./a.out", sender=self)

There are cases when sender is None.  This is the case when the @classmethod is
involved in the use of these APIs.  When this happens, there is no recording
into a session object, but printing on the sys.stderr is still honored if the
trace flag is ON.

An example is in test/settings/TestSettings.py:

    @classmethod
    def classCleanup(cls):
        system(["/bin/sh", "-c", "rm -f output.txt"])
        system(["/bin/sh", "-c", "rm -f stdout.txt"])

Johnny Chen 27b107b800 Add a test case for exercising breakpoint conditions using the lldb command:
breakpoint modify -c 'val == 3' 1

after:

    breakpoint set -n c

which sets a breakpoint on function 'c'.  The breakpoint should only stop if
expression 'val == 3' evaluates to true.

Johnny Chen 150c3cc825 This is an initial version of test driver enhanceent to be able to dump the
session info after a test case failure, allowing more direct inspection of
debugger session which leads to the test failure.

For a simple usage scenario:

[18:06:26] johnny:/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v . 2> ~/Developer/Log/lldbtest.log 

...

[18:14:43] johnny:/Volumes/data/lldb/svn/trunk/test $ ls -l .session-*

The test case which failed will have its recorded session info dumped to a
.session-* file in the current working directory.  For test suite using
relocated directory, expect to find the .session-* files there.

In this checkin, I also add @skip decorator to the two test methods in
test/foundation/TestObjCMethods.py as it looks like the test suite is
deadlocking when running the tests.  More investigations are needed.

Johnny Chen c066ab4385 Add an initial version of test that exercise the lldb commands: 'process signal'
and 'process handle'.  The test suite would like to control the asynch/sync
execution of the interpreter during the middle of the test method, so the
CommandInterpreter::SetSynchronous(bool value) is modified to allow the mode to
be changed more than once.

In practice, it would be advisable to control the process and to set the
async/sync mode from a single thread, too.

Johnny Chen 47ceb03210 Add a utility function to lldbtest.py to return the line number of a matched string
within a file.  This is to be used within the test case to avoid hardcoded line number.

array_types/TestArrayTypes.py is modified first to use this pattern.  Other test modules
to follow.

2010-10-11 23:52:19 +00:00
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 65045f2168 o TestStdCXXDisassembly.py:
Update the expected match string.

o lldbtest.py:

  Indicate when a command fails, even if there is nothing in the error stream.

o TestHelp.py:

  Add a regression test case for 'help image dump symtab'.

o CommandObjectHelp.cpp:

  Some of the logic branches with successful help command results were not tagged
  with a Success Status.  They are fixed now.  This is important for Python
  interaction.

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.

2010-10-05 19:27:32 +00:00
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 b052f6c595 Added a generic_type_tester() to the TestBasicTypes class to be used for
testing various combinations of displaying variales of basic types.

The generic_type_tester() works by first capturing the golden output produced
by the printf stmts of ./a.out, creating a list of (var, value) pairs, and then
running the a.out to a stop point, and comparing the 'frame variable var' output
against the list of (var, value) pairs.

Modified int_type() and added long_type() to use generic_type_tester().

Also modified TestBase.expect() such that substring matching also return ok if
the substring starts at the 0-th position.

Johnny Chen c70b02a324 Checked in an initial template for the types directory. Right now, it doesn't
actually test-and-compare anything yet.  The lldbtest.TestBase has an added
method setTearDownCleanup(dictionary=None) to facilitate running the cleanup
right after each data type test is run.  The test case can pass a dictionary
object when registering the test case cleanup.

There is currently only int_type test in the repository.

Johnny Chen 9c48b8d79c Added a subtest to exercise the capability of lldb Python objects to print
themselves.  Right now, it tests a breakpoint both before and after it has been
resolved.

Updated lldbtest.TestBase.expect() with an additional keyword argument 'exe' (
default to True), which if set to False, will treat the mandatory first argument
as just the string to be matched/or not-matched against the golden input.

2010-09-21 23:33:30 +00:00
Johnny Chen 90312a8492 Wrapped the subclass-specific cleanup call within a try:except: clause.
And removed the informational output from the conditional_break test case.

llvm-svn: 114493
2010-09-21 22:34:45 +00:00
Johnny Chen ea88e94318 Added a more complex test case of breakpoint commands, which executes a sequence
of 'breakpoint command add/list/remove' commands to set breakpoint callbacks,
list them, and then remove one.

Modified the lldbtest.TestBase.expect() method to add two additional keyword
arguments:

o matching (default to True), which, if set to False, reverses the semantics of
  'expect' to 'expect not'

o patterns (default to None), which specifies a list of regexp patterns to match
  against the output from running the command

TestBreakpointCommand.py uses the matching=False and the patterns=[...] expect()
API.

2010-09-17 22:45:27 +00:00
Johnny Chen b330786d1f Added test cases to FoundationTestCase to exercise lookup of objc data types and
to evaluate expressions.  Marked with @expectedFailure decorators for the time
being.

Enhanced the lldbtest.TestBase.expect() API to allow an additional keyword arg
named "error".  If the client passes "error=True", it signifies that an error
while running the command is expected.  The golden input is then compared
against the return object's error output.

llvm-svn: 114228
2010-09-17 22:28:51 +00:00
Johnny Chen 2fcc0e5555 Added a test case for the settings command which sets process.output-path and
checks that the launched process writes its standard output there.

llvm-svn: 114102
2010-09-16 18:26:06 +00:00
Johnny Chen 1a9f4dd5a0 Provided a mechanism for the test class to cleanup after itself once it's done.
This will remove the confusion experienced when previous test runs left some
files (both intermediate or by-product as a result of the test).

lldbtest.TestBase defines a classmethod tearDownClass(cls) which invokes the
platform-specific cleanup() function as defined by the plugin; after that, it
invokes a subclass-specific function classCleanup(cls) if defined; and, finally,
it restores the old working directory.

An example of classCleanup(cls) is in settings/TestSettings.py:

    @classmethod
    def classCleanup(cls):
        system(["/bin/sh", "-c", "rm output.txt"])

where it deletes the by-product "output.txt" as a result of running a.out.

Johnny Chen f7f0cabe9f We believed the intermittent process launch failure while running the test suite

2010-09-15 17:33:57 +00:00
Johnny Chen ae74556ff6 Added two test cases to exercise 'expr this->m_c_int' with @expectedFailure
decorators for the time being.

llvm-svn: 113905
2010-09-15 00:00:54 +00:00
Johnny Chen e049051e68 More appropriate headings for the traceoutput: stdout & stderr.

2010-09-14 22:39:02 +00:00
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

2010-09-14 22:01:40 +00:00
Johnny Chen 1394a4b715 Extend the build mechanism to allow for specifying the compiler used to build
the binaries.

If the build* function is passed the compiler argument, for example, 'llvm-gcc',
it is passed as a make variable to the make command.  Otherwise, we check the
LLDB_CC environment variable; if it is defined, it is passed as a make variable
to the make command.

If neither the compiler keyword argument nor the LLDB_CC environment variable is
specified, no CC make variable is passed to the make command.  The Makefile gets
to define the default CC being used.

--------------------------------------------------------------------------------
Example usage follows:

o Via the keyword argument:

class ArrayTypesTestCase(TestBase):

    mydir = "array_types"

    @unittest2.skipUnless(sys.platform.startswith("darwin"), "requires Darwin")
    def test_with_dsym_and_run_command(self):
        """Test 'frame variable var_name' on some variables with array types."""
        self.buildDsym(compiler='llvm-gcc')
        self.array_types()
...

o Via LLDB_CC environment variable:

$ LLDB_CC=llvm-gcc ./dotest.py -v -t array_types
----------------------------------------------------------------------
Collected 4 tests

test_with_dsym_and_python_api (TestArrayTypes.ArrayTypesTestCase)
Use Python APIs to inspect variables with array types. ... 
os command: [['/bin/sh', '-c', 'make clean; make MAKE_DSYM=YES CC=llvm-gcc']]

2010-09-03 23:49:16 +00:00
Johnny Chen 725945d568 Fixed an lldb infrastructure bug, where the debugger should reaaly update its
execution context only when the process is still alive.  When running the test
suite, the debugger is launching and killing processes constantly.

This might be the cause of the test hang as reported in rdar://problem/8377854,
where the debugger was looping infinitely trying to update a supposedly stale
thread list.

llvm-svn: 113022
2010-09-03 22:35:47 +00:00
Johnny Chen 57b47384cc Added comments regarding the two mechanisms of process cleanup to lldbtest.py.

2010-09-02 22:25:47 +00:00
Johnny Chen 7d1d7537cf Moved the process cleanup of Script-Bridge-based APIs into TestBase.tearDown()
method where they belong.  Also fixed a logic error in maintaining the command

command has been issued.  It was erroneously cleared.

Modified the test cases to take advantage of the refactoring.

Johnny Chen 63dfb27647 Avoid killing the inferior process twice by passing a setCookie=False keyword
argument when issuing a "run" lldb command within the test case meant to
exercise the Python APIs, but is using the command interface due to certain
reason (such as target.LaunchProcess() does not reliably bring up the inferior).

llvm-svn: 112682
2010-09-01 00:15:19 +00:00
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.

llvm-svn: 112606
2010-08-31 17:42:54 +00:00
Johnny Chen 324355b9a1 Added doc strings to the array_types test cases. And terminate the current

2010-08-30 23:44:39 +00:00
Johnny Chen a33a93cbde Converted TestArrayTypes.py to Dsym/Dwarf combination, and added verbose output
of os command to lldbtest.TestBase.system() method.

llvm-svn: 112547
2010-08-30 23:08:52 +00:00
Johnny Chen 2f1ad5e2bd Added buildDsym() and buildDwarf() methods to lldbtest.TestBase class, and call
them from test cases instead of issuing "make clean; make ..." os command.

llvm-svn: 112542
2010-08-30 22:26:48 +00:00
Johnny Chen 8952a2d5b6 Added a system() method to the TestBase class of lldbtest.py, which is actually
taken from Python 2.7's subprocess.check_output() convenience function.  The
purpose of this method is to run the os command with arguments and return its
output as a byte string.

Modified hello_world/TestHelloWorld.py to have two test cases:

o test_with_dsym_and_run_command
o test_with_dwarf_and_process_launch_api

with the dsym case conditioned on sys.platform.startswith("darwin") being true.
The two cases utilize the system() method to invoke "make clean; make MAKE_DYSM=YES/NO"
to prepare for the appropriate debugging format before running the test logic.

2010-08-30 21:35:00 +00:00
Johnny Chen 5ee881948a Added a test case test_breakpoint_creation_by_filespec_python() which creates a

Also, RUN_STOPPED is a bad assert name, RUN_SUCCEEDED is better.

llvm-svn: 112327
2010-08-27 23:47:36 +00:00
Johnny Chen 82d404c886 Added TestHelloWorld.py which exercises the Python APIs for target, breakpoint,
