InfernoDISCLAIMER: This is a big WIP. I'm also very tired so this is probably extremely incoherent.
None of the current PHP unit testing frameworks work for me; I want to include a library into my application and be able to run a file at the command line and see my test results. I don't want to install PEAR packages. I don't want to include about a hundred files. I don't want to have to open up the browser.
Inferno is a really quick, lightweight and simple to use PHP unit testing solution. It's based on the xUnit testing pattern and it's designed for testing small classes, libraries and other bits of code. It's not meant for massive codebases, rather, it's meant as a nice, coherent way of testing a standalone library or a group of small files.
