#define TEUCHOS_TEST_THROW	(	code,
		ExceptType,
		out,
		success
	)

Test that the chunk of code 'code' throws an expected exception.

'code' is a chunk of code to execute. It will be executed exactly once. If it throws an exception of type ExceptType, this test passes (and prints "passed"). Otherwise, it prints "failed" with an informative message. The macro prints all messages to the given output stream (std::ostream&) out. Furthermore, if the test passes, it assigns true to success; if the test fails, it assigns false to success.

The macro's implementation does not evaluate 'out' more than once.

      l_out << "Test that code {"#code";} does not throw : "; \
      code; \
      l_out << "passed\n"; \
    } \
    catch (std::exception& except) { \
      (success) = false; \
      l_out << "The code was not supposed to throw an exception, but " \

      (success) = false; \
      l_out << "The code was not supposed to throw an exception, but " \
            << "instead threw an exception of some unknown type, which is " \

Compare if two array objects are the same or not.

This function works with any two array-like objects: Array1 and Array2 must have size() and operator[](i) methods defined. Their element types may be different, but it must be possible to compare them with ==.

Returns: Returns true if a1.size() == a2.size() and their elements are equal. Otherwise returns false.

		Teuchos::FancyOStream &	out
	)

Compare if two array objects are the same or not up to a relative floating point precision.

This function works with any two array-like objects: Array1 and Array2 must have size() and operator[](i) methods defined. Their element types may be different, as long as Teuchos::relErr(a1[i], a2[i]) can be called to determine the relative difference between them.

Returns: Returns true if a1.size() == a2.size() and relErr(a1[i], a2[i]) <= tol for all 0 <= i < a1.size(). Otherwise returns false.

		Teuchos::FancyOStream &	out
	)

Compare if two array objects are the same up to an absolute tolerance: elements a1[i] and a2[i] are considered the same if |a1[i]-a2[i]| <= tol.

This function works with any two array-like objects with the same element types. Array1 and Array2 must have size() and operator[](i) methods defined. Teuchos::ScalarTraits must also have a specialization for the element type.

Returns: Returns true if a1.size() == a2.size() and |a1[i]-a2[i]| <= tol for all 0 <= i < a1.size(). Otherwise returns false.
