Pact Foundation

In bidirectional contract testing example, newman results, swagger.yml and pact.json deletes existing for every run

Are you referring to this step: <https://github.com/pactflow/example-bi-directional-provider-postman/blob/master/package.json#L8>

Is there a reason why you wanted to know that?

You should always generate a new pact contract each testing session, so that you don’t have old/outdated interactions (test) in them

On the provider side, we want to make sure we upload a correct contract

While generating swagger file from postman collection can we specify required fields and optional fields

I don’t think so, at least not using the tools I’ve seen.
