Functions
void	gmx::test::internal::processExpectedException (const std::exception &ex)
	Called for an expected exception from EXPECT_THROW_GMX(). More...
void	gmx::test::checkTestNameLength (std::optional< std::string > testName=std::nullopt)
	Gives a GoogleTest assertion if the test's name is too long. More...
Helper functions for computing floating-point differences
These routines are used to initialize FloatingPointDifference. They peek into some internal types from Google Test (gtest-internal.h), and duplicate some other functionality from there, but that is likely a better alternative than just copying all that code here.
template<typename FloatType >
FloatingPoint< FloatType >::Bits	gmx::test::anonymous_namespace{testasserts.cpp}::floatingPointToBiasedInteger (const FloatingPoint< FloatType > &value)
	Computes biased integer representation for a floating-point value. More...
template<typename FloatType >
uint64_t	gmx::test::anonymous_namespace{testasserts.cpp}::calculateUlpDifference (const FloatingPoint< FloatType > &value1, const FloatingPoint< FloatType > &value2)
	Computes the magnitude of the difference in ULPs between two numbers, treating also values of different sign.
template<typename FloatType >
void	gmx::test::anonymous_namespace{testasserts.cpp}::initDifference (FloatType raw1, FloatType raw2, double *absoluteDifference, uint64_t *ulpDifference, bool *bSignDifference)
	Helper to implement the constructors for FloatingPointDifference.
template<typename FloatType >
uint64_t	gmx::test::anonymous_namespace{testasserts.cpp}::relativeToleranceToUlp (FloatType tolerance)
	Converts a relative tolerance into an ULP difference.

Variables
bool	gmx::test::anonymous_namespace{testasserts.cpp}::g_showExpectedExceptions = false
	Whether to print the message from expected exceptions.
