There are no cucumber features for knife

There are no cucumber features for knife so it is extremely difficult to know if a patch will break some aspect of knife. For example, there was a patch that fixed problems daemonizing by making chef applications cd to /. This broke all knife commands that used relative paths, like cookbook uploading, but it was not easy to discover this bug because it would not happen if you used a path like ~/my-cookbooks/ when uploading. So we need integration and regression tests for knife.
