|

// -----------------------------------------------------------------------------

|
|
// printing of test results.
|
|
|
|
// NOTE: Configuration
|
|
// -----------------------------------------------------------------------------
|
|
// #define DQN_UTEST_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_UTEST_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_UTEST_RESULT_PAD_CHAR
|
|
// Define this to a character to specify the default character to use for
|
|
// padding. By default this is '.'
|
|
//
|
|
// #define DQN_UTEST_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_UTEST_BAD_COLOR
|
|
// Define this to a terminal color code to specify what color errors will be
|
|
// presented as.
|
|
//
|
|
// #define DQN_UTEST_GOOD_COLOR
|
|
// Define this to a terminal color code to specify what color sucess will be
|
|
// presented as.
