Mineunit demo spec

[S-S-X]

This most likely isn't that useful as is but thought I'd share it now that I've already did it.

Also not exactly unit testing but a bit more like integration testing (or could we even call it interaction testing, smoke testing it is anyway).

So I found this old issue and it was interesting as I've been test driving some formspec utilities for mineunit:

• Unit Testing with Mineunit #12

Basically this to execute echo Hello World on modular_computers:computer:

-- Maybe it does something if we'd right click it
player:do_place_from_above({x=1, y=1, z=1})

-- We should have received a formspec, parse it and find input field
local form1 = mineunit:get_player_formspec(player)
assert.is_Form(form1)
local input = form1:one("_in$", "field")
assert.not_nil(input)

-- Try some fancy command and send the form
input:value("echo Hello World")
form1:send(player)

-- Get response form and output field
local form2 = mineunit:get_player_formspec(player)
assert.is_Form(form2)
local output = form2:one("_out$", "textarea")
assert.not_nil(output)

-- Check if output matches expected value which is our command and its output
assert.match("echo Hello World\nHello World", output:value())
