Example 2 with LFRuntimeModule

use of org.lflang.LFRuntimeModule in project lingua-franca by lf-lang.

the class TestBase method runSingleTestAndPrintResults.

 *                  and not a new instance because this method needs to ensure the object
 *                  is properly injected, and so, it needs to control its entire lifecycle.
 * @param level     Level to which to run the test.
