Nice 👍
Just some documentation and test minor-changes needed in my opinion.

Small revision, will need an update in StepFunctionsRestApiProps as well.

+And in `StepFunctionsRestApi`, method response models (`methodResponses`) with 200, 400 and 500 status codes are added by default.

And in `StepFunctionsRestApi`, method response models (`methodResponses`) with 200, 400 and 500 status codes are added by default.

If you don't want to add default method response models, you can set `useDefaultMethodResponses` to `false` as follows:

```ts fixture=stepfunctions

new apigateway.StepFunctionsRestApi(this, 'StepFunctionsRestApi', {

stateMachine: machine,

useDefaultMethodResponses: false,

});

To disable default response models generation use the `useDefaultMethodResponses` property:

```ts

new apigateway.StepFunctionsRestApi(this, 'StepFunctionsRestApi', {

stateMachine: machine,

useDefaultMethodResponses: false,

});

I would move this here.

Thanks, I changed. Please review them again.

Thanks, just a minor adjustment and it will be good to go for me.

Thanks, I changed it.

Thanks 👍

Any reason to not have an integ test for the StepFunctionsRestApi invocation? Otherwise looks good to go.

Pull request has been modified.

@scanlonp

I was satisfied with just the StepFunctionsIntegration.startExecution test. I added that integ test.

I did not want to interfere with the behavior of the existing StepFunctionsRestApi test with useDefaultMethodResponses is true as a default value, so I added a new test.

scanlonp

Great, thanks for the new integ test. The optional parameter is a good way to disable automatic behavior, and the tests cover both the template validation and deploy success.
