💭 inline-snapshot

This is a cool snapshot testing tool that automatically creates, and updates test values for you.

Starting with some test code.

from inline_snapshot import snapshot


def something():
    return 1548 * 18489


def test_something():
    assert something() == snapshot()

now if I run pytest my tests will fail because my assert will fail, but if I run pytest --inline-snapshot=create it will fill out my snapshot values and the file will then look like this.

from inline_snapshot import snapshot


def something():
    return 1548 * 18489


def test_something():
    assert something() == snapshot(28620972)
