"""
LLDB module which provides the abstract base class of lldb test case.
The concrete subclass can override lldbtest.TesBase in order to inherit the
common behavior for unitest.TestCase.setUp/tearDown implemented in this file.
The subclass should override the attribute mydir in order for the python runtime
to locate the individual test cases when running as part of a large test suite
or when running each test case as a separate python invocation.
./dotest.py provides a test driver which sets up the environment to run the
entire test suite. Users who want to run a test case on its own can specify the
LLDB_TEST and PYTHONPATH environment variables, for example:
$ export LLDB_TEST=$PWD
$ export PYTHONPATH=/Volumes/data/lldb/svn/trunk/build/Debug/LLDB.framework/Resources/Python:$LLDB_TEST
$ echo $LLDB_TEST
/Volumes/data/lldb/svn/trunk/test
$ echo $PYTHONPATH
/Volumes/data/lldb/svn/trunk/build/Debug/LLDB.framework/Resources/Python:/Volumes/data/lldb/svn/trunk/test
$ python function_types/TestFunctionTypes.py
.
