Passing ignoreCanvasSerializationErrors in snapshot options or at global config. ignore any errors that occur during canvas serialization. And instead renders a broken Img.

• Adds comprehensive test coverage for the new functionality

test/index.test.mjs:3

• The import statement adds ignoreCanvasSerializationErrors but there are no integration tests verifying that percySnapshot properly uses this function internally. Consider adding a test that verifies the integration between percySnapshot and ignoreCanvasSerializationErrors.

import percySnapshot, { ignoreCanvasSerializationErrors } from '../index.js';

test/index.test.mjs:609

• This test doesn't verify the scenario where options.ignoreCanvasSerializationErrors is explicitly undefined vs when the property doesn't exist. The function uses optional chaining, so both cases should be tested to ensure proper fallback behavior.

  it('should fall back to utils.percy.config.snapshot.ignoreCanvasSerializationErrors when options value is undefined', () => {

test/index.test.mjs:623

• This test creates a config object with an empty snapshot property but doesn't test the case where utils.percy.config.snapshot itself is undefined or null. Consider adding a test case where the entire config path is missing.
