#if !defined(DQN_TESTER_H)

//
// NOTE: Overview
// -----------------------------------------------------------------------------
// A super minimal testing framework, most of the logic here is the pretty
// printing of test results.
// NOTE: Configuration
// -----------------------------------------------------------------------------
// #define DQN_TESTER_IMPLEMENTATION
// Define this in one and only one C++ file to enable the implementation
// code of the header file. This will also automatically enable the JSMN
// implementation.
//
// #define DQN_TESTER_RESULT_LPAD
// Define this to a number to specify how much to pad the output of the test
// result line before the test result is printed.
//
// #define DQN_TESTER_RESULT_PAD_CHAR
// Define this to a character to specify the default character to use for
// padding. By default this is '.'
//
// #define DQN_TESTER_SPACING
// Define this to a number to specify the number of spaces between the group
// declaration and the test output in the group.
//
// #define DQN_TESTER_BAD_COLOR
// Define this to a terminal color code to specify what color errors will be
// presented as.
//
// #define DQN_TESTER_GOOD_COLOR
// Define this to a terminal color code to specify what color sucess will be
// presented as.
// NOTE: Macros
// -----------------------------------------------------------------------------
