EXPECT_COMPARABLE

#define EXPECT_COMPARABLE	(		expected,
			obtained,
			epsilon
	)

Value:

  EXPECT_TRUE(operations_research::AreWithinAbsoluteOrRelativeTolerances( \
      expected, obtained, epsilon, epsilon))                              \
      << obtained << " != expected value " << expected                    \
      << " within epsilon = " << epsilon;

EXPECT_NOTCOMPARABLE

#define EXPECT_NOTCOMPARABLE	(		expected,
			obtained,
			epsilon
	)

Value:

  EXPECT_FALSE(operations_research::AreWithinAbsoluteOrRelativeTolerances( \
      expected, obtained, epsilon, epsilon))                               \
      << obtained << " == expected value " << expected                     \
