Demonstrate test environment prerequisite setup and teardown

### Expected Behavior
For a given C++/Swift test component, set up the environment before the test runs and teardown the environment after the test. For example, a test component may require a MySQL database to be running before the test execute.

The issue names no files, tests, or entry points. Start by locating the C++ and Swift test-component configuration and determine how prerequisite environments, such as a MySQL database, can be started before tests and torn down afterward. Done means both setup and teardown are supported for a given test component.
