"""
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.
Type:
./dotest.py -h
for available options.

Examples:
This is an example of using the -f option to pinpoint to a specific test class
and test method to be run:
$ ./dotest.py -f ClassTypesTestCase.test_with_dsym_and_run_command
----------------------------------------------------------------------
Collected 1 test
test_with_dsym_and_run_command (TestClassTypes.ClassTypesTestCase)
Test 'frame variable this' when stopped on a class constructor. ... ok
----------------------------------------------------------------------
Ran 1 test in 1.396s
OK
And this is an example of using the -p option to run a single file (the filename
matches the pattern 'ObjC' and it happens to be 'TestObjCMethods.py'):
$ ./dotest.py -v -p ObjC
----------------------------------------------------------------------
Collected 4 tests
test_break_with_dsym (TestObjCMethods.FoundationTestCase)
Test setting objc breakpoints using '_regexp-break' and 'breakpoint set'. ... ok
test_break_with_dwarf (TestObjCMethods.FoundationTestCase)
Test setting objc breakpoints using '_regexp-break' and 'breakpoint set'. ... ok
test_data_type_and_expr_with_dsym (TestObjCMethods.FoundationTestCase)
Lookup objective-c data types and evaluate expressions. ... ok
test_data_type_and_expr_with_dwarf (TestObjCMethods.FoundationTestCase)
Lookup objective-c data types and evaluate expressions. ... ok
----------------------------------------------------------------------
Ran 4 tests in 16.661s
OK
Running of this script also sets up the LLDB_TEST environment variable so that
individual test cases can locate their supporting files correctly. The script
tries to set up Python's search paths for modules by looking at the build tree
relative to this script. See also the '-i' option in the following example.
Finally, this is an example of using the lldb.py module distributed/installed by
Xcode4 to run against the tests under the 'forward' directory, and with the '-w'
option to add some delay between two tests. It uses ARCH=x86_64 to specify that
as the architecture and CC=clang to specify the compiler used for the test run:
$ PYTHONPATH=/Xcode4/Library/PrivateFrameworks/LLDB.framework/Versions/A/Resources/Python ARCH=x86_64 CC=clang ./dotest.py -v -w -i forward
Session logs for test failures/errors will go into directory '2010-11-11-13_56_16'
----------------------------------------------------------------------
Collected 2 tests
test_with_dsym_and_run_command (TestForwardDeclaration.ForwardDeclarationTestCase)
Display *bar_ptr when stopped on a function with forward declaration of struct bar. ... ok
test_with_dwarf_and_run_command (TestForwardDeclaration.ForwardDeclarationTestCase)
Display *bar_ptr when stopped on a function with forward declaration of struct bar. ... ok
----------------------------------------------------------------------
Ran 2 tests in 5.659s
OK
The 'Session ...' verbiage is recently introduced (see also the '-s' option) to
notify the directory containing the session logs for test failures or errors.
In case there is any test failure/error, a similar message is appended at the
end of the stderr output for your convenience.
ENABLING LOGS FROM TESTS
Option 1:
Writing logs into different files per test case::
This option is particularly useful when multiple dotest instances are created
by dosep.py
$ ./dotest.py --channel "lldb all"
$ ./dotest.py --channel "lldb all" --channel "gdb-remote packets"
These log files are written to:
<session-dir>/<test-id>-host.log (logs from lldb host process)
<session-dir>/<test-id>-server.log (logs from debugserver/lldb-server)
<session-dir>/<test-id>-<test-result>.log (console logs)
By default, logs from successful runs are deleted. Use the --log-success flag
to create reference logs for debugging.
$ ./dotest.py --log-success
Option 2: (DEPRECATED)
The following options can only enable logs from the host lldb process.
Only categories from the "lldb" or "gdb-remote" channels can be enabled
They also do not automatically enable logs in locally running debug servers.
Also, logs from all test case are written into each log file
o LLDB_LOG: if defined, specifies the log file pathname for the 'lldb' subsystem
with a default option of 'event process' if LLDB_LOG_OPTION is not defined.
o GDB_REMOTE_LOG: if defined, specifies the log file pathname for the
'process.gdb-remote' subsystem with a default option of 'packets' if
GDB_REMOTE_LOG_OPTION is not defined.
