 * BoundedContext} using a builder which implementing classes must {@linkplain #contextBuilder()
 * provide}. The context under the test is created {@linkplain BeforeEach before each} test method
 * and closed {@linkplain AfterEach after each} test method automatically.
 *
 * <p>Testing methods {@linkplain #context() obtain the context} for:
 * <ol>
 *     <li>Sending signals under the test to the context via {@code receivesXxx()} methods, such as
 *         {@link BlackBoxBoundedContext#receivesCommand(CommandMessage) receivesCommand()}.
 *     <li>Asserting results of handling the signals via {@code assertXxx()} methods,
 *     e.g. {@link BlackBoxBoundedContext#assertEvents() assertEvents()}.

 *
 * <p>Test suites derived from this class must NOT close the context directly. Doing so will fail
