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
|
|
.
