Detailed Description

template<class T>
struct micro_os_plus::micro_test_plus::to_t< T >

Since

3.2.0

The to_t template provides a public, strongly-typed wrapper for any type T, enabling explicit conversion of dynamic values and expressions to a type recognised by the µTest++ comparators and reporting mechanisms.

This wrapper inherits from type_traits::value<T>, ensuring that the encapsulated value is treated as the specified type within the framework. It is particularly useful for enhancing type safety and clarity in test expressions, especially when working with user-defined or less common types.

Example

MyType obj;
auto wrapped = to_t<MyType>{obj}; // Explicitly treat obj as MyType for
test comparison

This file is intended solely for internal use within the framework and should not be included directly by user code.

Member Data Documentation

epsilon

template<class T>

T micro_os_plus::micro_test_plus::type_traits::value< T >::epsilon = T{}

inherited

This instance member defines the precision for comparisons. It is set via the constructor, either explicitly or computed as a default based on the number of decimal digits in the value. Each instance carries its own epsilon, so two value<T> objects with different precisions do not interfere with each other.
