jmajors created this revision.
Herald added a subscriber: mgorny.
This is a new C++ test framework based on Google Test, and one working
example test.
The intention is to replace the existing tests in
packages/Python/lldbsuite/test/tools/lldb-server/ with this suite
and use this framework for all new client server tests.
