### Question:
RangeUtils { public boolean isBefore(Position after, Position before) { return compareTo(after, before) < 0; }  boolean isInsideRange(DocumentSymbol outerSymbol, DocumentSymbol innerSymbol); boolean isInsideRange(Range outerRange, Range innerRange); int compareTo(Position first, Position second); boolean isAfter(Position before, Position after); boolean isBefore(Position after, Position before);  }### Answer:
@Test public void isBeforePositive() { assertTrue(RangeUtils.isBefore(firstLine, secondLine)); }
@Test public void isBeforeNegative() { assertFalse(RangeUtils.isBefore(secondLine, firstLine)); }
