Testing tools

Detailed Description

Convenient tools for checking nda::basic_array and nda::basic_array_view objects with googletest.

Macros
#define	EXPECT_ARRAY_EQ(X, Y)
	Macro that expects array_are_equal to return true.
#define	EXPECT_ARRAY_NEAR(X, ...)
	Macro that expects array_are_close to return true.
#define	EXPECT_ARRAY_ZERO(X)
	Macro that expects array_almost_zero to return true.
#define	EXPECT_CLOSE(X, Y)
	Macro that expects generic_are_near to return true.
#define	EXPECT_COMPLEX_NEAR(X, ...)
	Macro that expects complex_are_close to return true.
#define	EXPECT_EQ_ARRAY(X, Y)
	Macro that expects array_are_equal to return true.

Functions
template<typename X>
::testing::AssertionResult	array_almost_zero (X const &x)
	Check that an array/view is close to zero, i.e. that its largest absolute element is less than 1e-10.
template<typename X, typename Y>
::testing::AssertionResult	array_are_close (X const &x, Y const &y, double precision=1.e-10)
	Check that two arrays/views are close, i.e. that they have the same shape and that the largest element of their absolute difference is less than a given precision.
template<typename X, typename Y>
::testing::AssertionResult	array_are_equal (X const &x, Y const &y)
	Check that two arrays/views are equal, i.e. that they have the same shape and the same elements.
template<typename X, typename Y>
::testing::AssertionResult	complex_are_close (X const &x, Y const &y, double precision=1.e-10)
	Check the absolute difference of two (complex) numbers.
template<typename X, typename Y>
::testing::AssertionResult	generic_are_near (X const &x, Y const &y)
	Check that that two generic objects are close, i.e. that their absolute difference is less than 1e-12.

array_almost_zero()

template<typename X>

::testing::AssertionResult array_almost_zero

(

X const &

x

)

#include <nda/gtest_tools.hpp>

Check that an array/view is close to zero, i.e. that its largest absolute element is less than 1e-10.

Template Parameters

X	Type of the array/view.

Parameters

x	Array/View.

Returns

::testing::AssertionSuccess() if the absolute value of every element is less than 1e-10. ::testing::AssertionFailure() otherwise.

array_are_close()

template<typename X, typename Y>

::testing::AssertionResult array_are_close	(	X const &	x,
		Y const &	y,
		double	precision = 1.e-10 )

#include <nda/gtest_tools.hpp>

Check that two arrays/views are close, i.e. that they have the same shape and that the largest element of their absolute difference is less than a given precision.

Template Parameters

X	Type of the first array/view.
Y	Type of the second array/view.

Parameters

x	First array/view.
y	Second array/view.
precision	Required precision for the comparison to be considered successful.

Returns

::testing::AssertionSuccess() if the arrays/view have the same shape and largest element of their absolute difference is less than a given precision. ::testing::AssertionFailure() otherwise.

Definition at line 104 of file gtest_tools.hpp.

array_are_equal()

template<typename X, typename Y>

::testing::AssertionResult array_are_equal	(	X const &	x,
		Y const &	y )

#include <nda/gtest_tools.hpp>

Check that two arrays/views are equal, i.e. that they have the same shape and the same elements.

Template Parameters

X	Type of the first array/view.
Y	Type of the second array/view.

Parameters

x	First array/view.
y	Second array/view.

Returns

::testing::AssertionSuccess() if the arrays/view have the same shape and the same elements, ::testing::AssertionFailure() otherwise.

Definition at line 75 of file gtest_tools.hpp.

complex_are_close()

template<typename X, typename Y>

::testing::AssertionResult complex_are_close	(	X const &	x,
		Y const &	y,
		double	precision = 1.e-10 )

#include <nda/gtest_tools.hpp>

Check the absolute difference of two (complex) numbers.

Template Parameters

X	Type of the first number.
Y	Type of the second number.

Parameters

x	First number.
y	Second number.
precision	Required precision for the comparison to be considered successful.

Returns

::testing::AssertionSuccess() if the absolute difference is less than the given precision, ::testing::AssertionFailure() otherwise.

Definition at line 53 of file gtest_tools.hpp.

generic_are_near()

template<typename X, typename Y>

::testing::AssertionResult generic_are_near	(	X const &	x,
		Y const &	y )

#include <nda/gtest_tools.hpp>

Check that that two generic objects are close, i.e. that their absolute difference is less than 1e-12.

Template Parameters

X	Type of the first object.
Y	Type of the second object.

Parameters

x	First object.
y	Second object.

Returns

::testing::AssertionSuccess() if the absolute value of their difference is less than 1e-12. ::testing::AssertionFailure() otherwise.
