[CentralOH] 2017-12-14 道場 Scribbles 落書/惡文? inotify on osx; parametrize tuples versus dict; pytest color; red green show; unittest versus pytest; dvorak and pytest

[jep200404 at columbus.rr.com]

What do OSX folks use instead of inotify to automatically run tests?

    while inotifywait -r -e modify src tests; do
        make
        make check
        cat tests/test-suite.log
    done

@pytest.mark.parametrize:

    collection of tuples versus dictionary

        using a dictionary inherently suggests input versus output.

            keys suggest input
            values suggest output

Someone who showed at CARPE a USB powered BRIGHT LED light
is interested in having it integrated with unit tests
to show the status in BRIGHT red or BRIGHT green.

tdd-demo base

    py.test -f --color=yes .
    pytest -f --color=yes .

    should write own pytest.approx() just for fun:
        class that overloads comparison functions

modify @pytest.mark.parametrize decorator:
    if there is only one argument,
    presume that tuple is a named tuple
    and get variable names from the named tuple
