ac77f3b2ac Turns out that the test failure wrt:
rdar://problem/9173060 lldb hangs while running unique-types

disappears if running with clang version >= 3.  Modify the TestUniqueTypes.py
to detect if we are running with clang version < 3 and, if true, skip the test.

Update the lldbtest.system() function to return a tuple of (stdoutdata, stderrdata)
since we need the stderr data from "clang -v" command.  Modify existing clients of
lldbtest.system() to now use, for example:

         # First, capture the golden output emitted by the oracle, i.e., the
         # series of printf statements.
-        go = system("./a.out", sender=self)
+        go = system("./a.out", sender=self)[0]
         # This golden list contains a list of (variable, value) pairs extracted
         # from the golden output.
         gl = []

And add two utility functions to lldbutil.py.

b877f1efe9 Add a test directory stop-hook to test the newly added "target stop-hook" command.
This uses pexpect module to spawn a 'lldb' program and uses pseudo-TTY to talk to
the child application.

The test cases test setting breakpoints, adding a stop-hook with line range, and
verifies that when the inferior stops, the stop-hook will fire off when it is
within range and will not fire off when it is out of range.

cf7f74e31c The test suite was unnecessarily doing a time.sleep() after performing the
"process launch" or "run" interpreter command.  Let's do the sleep only if
the process launch failed.  This saves about 135 seconds from the whole test
suite run time.

f3e22ac3c7 Add a '+a' command line option to the test driver to run only the Python API tests.

7c7d936e48 Add an infrastructure to mark the Python APIs only test using a decorator.
Example:

    @python_api_test
    def test_evaluate_expression_python(self):
        """Test SBFrame.EvaluateExpression() API for evaluating an expression."""
    ...

The opposite of Python APIs only test is an lldb command line test, which sends
commands to the lldb command interpreter.  Add a '-a' option to the test driver
to skip Python API only tests.

Modify TestExprs.py to mark a test as @python_api_test and remove an @expectedFailure
decorator as the bug has been fixed.

75739045d3 Add a '-b blacklistFile' option to the test driver to take a file specifying the
test classes or test cases to be excludued from the test suite.

Check in an example blacklist file: blacklist.py:

"""
'blacklist' is a Python dictionary, it stores the mapping of a string describing
either a testclass or a testcase, i.e, testclass.testmethod, to the reason (a
string) it is blacklisted.

Following is an example which states that test class IntegerTypesExprTestCase
should be skipped because 'This test class crashed' and the test case
FoundationTestCase.test_data_type_and_expr_with_dsym should be skipped because
it is 'Temporarily disabled'.

blacklist = {'IntegerTypesExprTestCase': 'This test class crashed',
             'FoundationTestCase.test_data_type_and_expr_with_dsym': 'Temporarily disabled'
             }
"""

blacklist = {}

An example of invoking the test driver and specifying a blacklist file:

./dotest.py -b blacklist.py -v types

This runs the tests under 'types' directory but excludes the tests specified in
balcklist.py.

c9ea0f8425 Add an expect() statement within breakpoint_conditions() method which tests that
the process status is indeed 'stopped' before invoking 'frame variable -t val'
command to inspect the frame variable.  When I run the test suite, it sometimes
emits an output like:

runCmd: frame variable -t val
runCmd failed!
error: you must be stopped in a valid stack frame to view frame variables.

The expect() statement inserted is to make sure that the process is stopped and
we have a valid frame.

110bd0f8cf Now that the test suite has very few expected failures remaining (2), it is a good
idea to also dump the session information for expected failures in addition to
failures and errors (tests with unexpected exceptions).

Modify the LLDBTestResult class which derives from unittest2.TextTestResult to
intercept the addExpectedFailure() method in order to mark the test instance as
needing its session information dumped.

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"])
