# IntegTestCaseProps

Properties of an integration test case.

Extends: IntegTestCaseProps
Extends: TestOptions, ProviderOptions
Used as props by: IntegTestCase

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/test-case.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/integ-tests-alpha/lib/test-case.ts#L15)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as integ_tests_alpha from '@aws-cdk/integ-tests-alpha';
import * as cdk from 'aws-cdk-lib';
import { aws_lambda as lambda } from 'aws-cdk-lib';
import { cloud_assembly_schema } from 'aws-cdk-lib';

## Properties

- `allowDeleteFailures`: boolean = false — Whether to allow resources that fail to delete during a stack update.

  When false, the test will fail if CloudFormation skips deleting a resource
  during a stack update. When true, only a warning is printed.

- `allowDestroy`: string[] — List of CloudFormation resource types in this stack that can be destroyed as part of an update without failing the test.

  **Default:** do not allow destruction of any resources on update

  This list should only include resources that for this specific
  integration test we are sure will not cause errors or an outage if
  destroyed. For example, maybe we know that a new resource will be created
  first before the old resource is destroyed which prevents any outage.

  e.g. ['AWS::IAM::Role']

- `assertionStack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) — Specify a stack to use for assertions.

  **Default:** a stack is created for you

- `cdkCommandOptions`: [CdkCommands](/cdk/api/v2/docs/aws-cdk-lib.cloud_assembly_schema.CdkCommands.html) — Additional options to use for each CDK command.

  **Default:** runner default options

- `diffAssets`: boolean = false — Whether or not to include asset hashes in the diff Asset hashes can introduces a lot of unneccessary noise into tests, but there are some cases where asset hashes _should_ be included.

  For example
  any tests involving custom resources or bundling

- `hooks`: [Hooks](/cdk/api/v2/docs/aws-cdk-lib.cloud_assembly_schema.Hooks.html) — Additional commands to run at predefined points in the test workflow.

  **Default:** no hooks

  e.g. { postDeploy: ['yarn', 'test'] }

- `providerLogLevel`: [ApplicationLogLevel](/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.ApplicationLogLevel.html) = ApplicationLogLevel.FATAL — The log level of the provider lambda function.

- `regions`: string[] — Limit deployment to these regions.

  **Default:** can run in any region

- `stacks`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html)[] (required) — Stacks to be deployed during the test.

- `stackUpdateWorkflow`: boolean = true — Run update workflow on this test case This should only be set to false to test scenarios that are not possible to test as part of the update workflow.
