pyariable 0.5.0

Placeholder variables to aid in testing.

Simplify your test assertions forever.

from pyariable import Variable

def test_dict():
    x = Variable()
    y = Variable()
    assert {1: "XXX", 2: "XXX", 3: "YYY"} == {1: x, 2: x, 3: y}
    assert x != y

In some tests it’s common to get a random ID back from a database. Your assertions are simpler when you substitute a Variable object for the expected value.

from pyariable import Variable

def test_list():
    x = Variable()
    y = Variable()
    assert [
        {"db_id": 590, "name": "alice"},
        {"db_id": 590, "name": "bob"},
        {"db_id": 999, "name": "charlie"},
    ] == [
        {"db_id": x, "name": "alice"},
        {"db_id": x, "name": "bob"},
        {"db_id": y, "name": "charlie"},
    ]
    assert x != y
    assert x < y
