Snapshots

Snapshot assertions compare the current value to a stored snapshot.

Example:

import { test, expect } from "as-test";

test("serializes payload", () => {
  expect("hello").toMatchSnapshot("greeting");
});

Useful commands:

ast test
ast test --update-snapshots
ast test --no-snapshot

Behavior:

• snapshots are stored in the configured snapshot directory
• --update-snapshots writes new or changed values
• --no-snapshot disables snapshot assertions for the run
