Detailed Description

template<typename T, typename U = T>
struct tts::ramp< T, U >

Defines a data generator that produce a ramp of data.

This generator produces a ramp starting from an initial value and increasing by a fixed step at each call. I.e., for a size N, the produced values are: start, start+step, start+2*step, ..., start+(N-1)*step.

Template Parameters

T	Type of the initial value
U	Type of the step value

Example

#define TTS_MAIN // No need for main()
#include <tts/tts.hpp>
#include <array>
 
TTS_CASE_WITH("Test tts::ramp generator",
              (std::array<float, 10>, int, double),
              tts::ramp {65},
              tts::ramp {1, 2})
<typename T>(T const& ramp1, T const& ramp2)
{
  if constexpr(std::is_arithmetic_v<T>)
  {
    TTS_EQUAL(ramp1, static_cast<T>(65));
    TTS_EQUAL(ramp2, static_cast<T>(1));
  }
  else
  {
    for(std::size_t i = 0; i < ramp1.size(); ++i)
    {
      TTS_EQUAL(ramp1[ i ], static_cast<typename T::value_type>(65 + i));
    }
    for(std::size_t i = 0; i < ramp2.size(); ++i)
    {
      TTS_EQUAL(ramp2[ i ], static_cast<typename T::value_type>(1 + i * 2));
    }
  }
};
