Code Snippet: Unit Test Green/Red Bar for ANSI Terminals
If you like writing unit tests but you don't have a fancy "green bar/red bar" unit test window, here's a simple solution you can use in any ANSI terminal window. It looks like this:
It's a piece of cake with some ANSI escape codes. Here's the code:
#include <stdio.h>
void printTestResults(int numPass, int numFail)
{
if (numFail > 0)
printf("\x1b[37;41m"); /* white on red */
else
printf("\x1b[30;42m"); /* black on green */
printf("\x1b[2K"); /* clear to end of line */
printf("Test results: %d pass, %d fail (%d total)\n",
numPass, numFail, numPass + numFail);
printf("\x1b[0m"); /* reset colors */
printf("\x1b[2K"); /* clear to end of line */
}
