I'd say `cfx testall` is obsolete, we should just make simple make file like: 

```makefile
test: test-jpm test-sdk test-examples

test-jpm:
	npm test

test-sdk:
	jpm test ./path/to/addon-sdk/

test-examples:
	jpm test ./path/to/addon-sdk/examples/reddit-panel
	# ....
```
Although we would need either `jpm` on tbpl or `jpm.py` that only know how to `jpm test`.
