failing snapshot for change in hashes of AssetParameters

[giorgio-zamparelli]

Snapshot aren't matching on the CI because of changes in the hashes of AssetParameters Ref
ignoreAssets: true is already defined and not fixing this.
Is this something fixable with Property matchers?

What are you building there? Can you show more of the cloudformation?

[giorgio-zamparelli]

Here it is @hupe1980 . The part that is changing is the hash of a Parameters containing a Ref to a S3Bucket. I'm using AWS CDK packages version 1.39.0

What are you building there? Can you show more of the cloudformation?

Here is the generated CloudFormation template in .json

All right. The bucketDeployment construct creates the assets. I think you can try propertyMatchers. IgnoreAssets currently only works for lambdas.

expect(stack).toMatchCdkSnapshot({
    ignoreAssets: true,
    propertyMatchers: {
      Resources: {
        BucketDeploymentAssetsCustomResource18D602EE: {
          Properties: {
            SourceBucketNames: expect.any(Array),
            SourceObjectKeys: expect.any(Array),
          }
        },
//...
      }
    }
  });

  });

Unfortunately this excludes any other resource from the test. Is there a way to include everything but just fine tune some of the resources?

In case somebody stumbles here based on a google search, here's a workaround that works with vanilla aws-cdk-lib/assertions and can most likely be adapted for uses case with jest-cdk-snapshot:

import { Template } from 'aws-cdk-lib/assertions';
test('Snapshot', () => {
  // SNIP
  const template = Template.fromStack(stack);

  /**
  * The template has a lambda function resource like this, where the S3Key changes whenever the lambda function code changes or when building codebase with different OS:
   * // SNIP
   "ExampleLambdaCCAF212F": Object {
      "DependsOn": Array [
        "ExampleLambdaServiceRoleDefaultPolicy40713755",
        "ExampleLambdaServiceRole598AA0D0",
      ],
      "Properties": Object {
        "Code": Object {
          "S3Bucket": "cdk-foobar-assets-1234567890-eu-west-1",
          "S3Key": "85a886236522b91357cf67203335e0662dd8de33034639086f260550c96f7aa6.zip",
        },
        "Handler": "index.handler",
   * // SNIP   
   */

  // Find as limited set of lambda functions from template as possible:
  const s = template.findResources('AWS::Lambda::Function', {
    Properties: {
      Handler: 'index.handler',
    }
  });
  console.log(JSON.stringify(s, null, 2));

  // Log the keys of the found resources, one of them should be ExampleLambdaCCAF212F
  const keys = Object.keys(s);
  console.log(keys);

  // In this case only one lambda function should be found
  expect(keys.length).toBe(1);

  const key = keys[0];

  // Verify the found lambda function resource key is the desired one:
  // This here uses jest-extended toStartWith matcher
  expect(key).toStartWith('ExampleLambda');

  const json = template.toJSON();
  // Finally, before performing the snapshot testing of the whole templte, replace the S3Key of the lambda function with a static value as we do not care about the hash value in this snapshot test 
  json.Resources[key].Properties.Code.S3Key = "REMOVED-BECAUSE-WE-ARE-NOT-INTERESTED-IN-LAMBDA-CODE-HASH-IN-THIS-TEST";

  // This passes even if the lambda function code of ExampleLambdaCCAF212F changes
  expect(json).toMatchSnapshot();
});

👋 after stumbling across this from a Google search (actually aws/aws-cdk#25410 (reply in thread)).

Here's another implementation I put together:

type TemplateJson = ReturnType<Template["toJSON"]>;

const replaceS3Key: (template: TemplateJson) => TemplateJson = (template) => {
  if (Array.isArray(template)) {
    return template.map((item) => replaceS3Key(item));
  } else if (template !== null && typeof template === "object") {
    for (let key in template) {
      if (template.hasOwnProperty(key)) {
        if (key === "S3Key") {
          template[key] = "NON-DETERMINISTIC VALUE. Replaced for tests only.";
        } else {
          template[key] = replaceS3Key(template[key]);
        }
      }
    }
  }
  return template;
};
