hecate 0.1.0

Are you serious?

Not very, no. As a concept it works and works well, and I’m fully prepared to maintain this if it proves popular, but this should be considered a semi experimental hack which just happens to be orders of magnitude better than all of the for serious mature projects you could be using instead.

On the other hand the last time I wrote a semi-experimental testing hack that just happened to be the best around (in Python), we got Hypothesis, so…

Will you support Python 2.7?

No.

Why not?

Because you shouldn’t need it and I don’t want to. Hecate scripts are stand alone applications that interact with your program through its terminal interface. You can easily test things written in any language you like, including other versions of Python.

What versions of tmux does it support?

My CI tests it on versions 1.6 through 2.0, so that’s the officially supported set. It probably works on earlier ones but I haven’t tested and am not very interested in doing so.

Why is it called Hecate?

It seemed appropriate to name a Selenium style tool for curses based applications after a goddess whose domain includes the moon and magic.

How does it work?

Behind the scenes Hecate is spawning a tmux instance and running your command with it along with a monitoring process so that we can report back the exit code (after all, who would make a testing framework that didn’t report the standard mechanism for indicating errors back to you?). Hecate interacts with the tmux server using its command line tools.

I might update it to use the control protocol at some point, but it so far doesn’t seem that useful to do so and that would limit the range of supported tmux versions or require a lot of version specific code.
