 Reproducers are tested in the following ways:
 
- - Unit tests to cover the generic reproducer infrastructure.
- - Focused test cases in the ``test/Shell/Reproducer`` directory. These tests
-   serve as integration tests for the reproducers infrastructure, as well as
-   doing some sanity checking for basic debugger functionality.

-Additional testing is possible:
-
- - It's possible to unconditionally capture reproducers while running the
-   entire test suite by setting the ``LLDB_CAPTURE_REPRODUCER`` environment
-   variable. Assuming the reproducers behave correctly, this can also help to
-   reproduce test failures.

    ``check-lldb-repro`` target will run the shell test suite twice. First it
    runs the test suite and captures a reproducer for every lldb invocation and
    saves it to a known ___location based off lldb's arguments and  working
    directory. Then it runs the test suite again, this time replaying the
    reproducers. Certain tests do not fit this paradigm (for example test that
-   check the output of the binary being debugged) and can be skipped by setting
-   ``UNSUPPORTED: lldb-repro`` at the top of the test.
