# Pytest - chaining test no setup repeats
# make this "all in one container" have a class to test here ;-)
this.stuff = stuff
this.others = others
result = this.others[name]
result = None
previous = this.get(name)
this.others[name] = value
result = this.others["width"] * this.others["depth"]
# -------- tests -------------------
rv = widget.w
widget.w = thing(4,6,8,height=16,width=24,depth=10)
rv = widget.w
assert widget.get("width") == 24
assert widget.getarea() == 240
old_depth = widget.set("depth",12)
assert old_depth == 10
assert widget.get("depth") == 12
# NOTE ... test 3 depends on the outcome of test two. This is horrid stuff
# and breaks all the rules I have been taught about keeping tests separate
# and I had to force the fixure by using a static member
# But there are times you'll want to do this if setup is timeconsuming and expensive
assert widget.getarea() == 288
