x in snapshot()

General

It is possible to check if an value is in a snapshot. The value of the generated snapshot will be a list of all values which are tested.

Example:

original code--inline-snapshot=create

from inline_snapshot import snapshot


def test_something():
    s = snapshot()

    assert 5 in s
    assert 5 in s
    assert 8 in s

    for v in ["a", "b"]:
        assert v in s

from inline_snapshot import snapshot


def test_something():
    s = snapshot([5, 8, "a", "b"])

    assert 5 in s
    assert 5 in s
    assert 8 in s

    for v in ["a", "b"]:
        assert v in s

pytest options

It interacts with the following --inline-snapshot flags:

• create create a new value if the snapshot value is undefined.
• fix adds a value to the list if it is missing.
• trim removes a value from the list if it is not necessary.
