Maybe this is because I have never done this before.</p><p>For example recently I wrote a identicons library, Penticons[1]. It generates GitHub contribution flavored identicons. You can read the development story here[2].</p><p>Now, the thing that stopped me from writing tests was, I thought that ultimately it's a image generation library, why this thing needs any tests.</p><p>I don't want to lost my 1 point in the Joel score. Whenever I see a <i>build passing</i> label on a GitHub repository, It makes me crazy.</p><p>I'm asking here because I just love HN, I know people will suggest some awesome things here.</p><p>1. https://github.com/penticons/penticons.go</p><p>2. http://pravj.github.io/blog/penticons-the-hash-game/</p>";
