zsh's completion system is very advanced, but that comes with a disadvantage: there is no easy way to dump the completions. The simplest way of doing that is printing them to stdout in a certain format, and then use the zpty module to parse that format and actually print them. There is no easier way. We also have to simulate `compadd` in order to output the list of completions in a way that is similar to the bash completion tests. The resulting test scripts is very close to the bash completion test script, except some tests don't make sense, and others require minor modifications.
