### Question:
TracingContextUtils { public static Span getCurrentSpan() { return getSpan(io.opentelemetry.context.Context.current()); } private  TracingContextUtils(); static Context withSpan(Span span, Context context); static Span getCurrentSpan(); static Span getSpan(Context context); @Nullable static Span getSpanWithoutDefault(Context context); static Scope currentContextWith(Span span);  }### Answer:
@Test void testGetCurrentSpan_Default() { Span span = TracingContextUtils.getCurrentSpan(); assertThat(span).isSameAs(DefaultSpan.getInvalid()); }
