Detailed Description

template<class Scalar>
class Thyra::VectorSpaceTester< Scalar >

Testing class for VectorSpace and the VectorBase and MultiVectorBase objects that it creates.

The testing function check() calls all of the methods defined in the interfaces VectorSpace, VectorBase, MultiVectorBase and VectorSpaceFactoryBase and checks may (but perhaps not all) of the postconditions. It would be very difficult to completely verify every postcondition in every situation.

The behavior of the testing function check() is strongly influenced by a set of options.

When writing new concrete implementations of VectorSpace, VectorBase, MultiVectorBase and VectorSpaceFactoryBase, a developer is likely to spend a lot of time debugging while in this testing function.

Constructor & Destructor Documentation

template<class Scalar >

Thyra::VectorSpaceTester< Scalar >::VectorSpaceTester	(	const ScalarMag	warning_tol = `1e-13`,
		const ScalarMag	error_tol = `1e-10`,
		const int	num_random_vectors = `1`,
		const int	num_mv_cols = `4`,
		const bool	show_all_tests = `false`,
		const bool	dump_all = `false`
	)

Default constructor which sets default parameter values.

Note: It is not recommended that the client pass in values in this constructor since the argument list may change in the near future but instead use the above set functions to change an option after construction.

template<class Scalar>

bool Thyra::VectorSpaceTester< Scalar >::check	(	const VectorSpaceBase< Scalar > &	vs,
		Teuchos::FancyOStream *	out
	)		const

Check a vector space and the objects it creates through a set of comprehensive tests.

Parameters

vs	[in] The vector space object to test.
out	[in/out] If `out != NULL` then output will be sent to `*out`.

The behavior of this function greatly depends on a number of options (see VectorSpaceTester() for the default values for these options):

print_all_tests(bool): If print_all_tests() == true, then some output will be sent to *out for every test performed. This is useful to see all of tests that are performed and in debugging.
dump_all(bool): If dump_all() == true, then all of the vectors will be printed that are created during the tests. This option is really only needed during initial debugging and should only be used with small vector spaces since it will produce a lot of O(space.dim()) output.
num_random_tests(int): This is the number of random tests to perform per category of test. A higher number will result is better validation but will consume more CPU time.
warning_tol(ScalarMag): Any test with a relative error greater than warning_tol() will result in a warning message printed to *out but will not result in a filed test.
error_tol(Scalar): Any test with a relative error greater than error_tol() will result in an error message printed to *out and will result in a failed test.

Returns: The function returns true if all of the tests where within the error_tol() and returns false if not.

The best way to see what this testing function is doing is to run the test with out!=NULL and to look at the implementation by clicking on the following link to the source code:
