/**
 * Allows to create one or more Bootique runtimes within a JUnit test, performing automatic shutdown of all created
 * runtimes at the end of the factory scope. Can be declared as a static or an instance variable in a test class
 * and annotated with {@link BQTestTool} (and the containing test class must be annotated with {@link BQTest}). Shutdown
 * of the managed runtimes is down based on the explicit (as defined in the {@link BQTestTool} annotation), or implied
 * scope of the factory.
