| PASS Can construct a payment request (smoke test). | |
| PASS PaymentResponse.prototype must have a retry() function (smoke test). | |
| PASS A completed payment request cannot be retried. | |
| PASS Calling retry() more than once yield a rejected promise, but the retryPromise resolves independently. | |
| PASS Calling complete() while a retry() is in progress results in an InvalidStateError. | |
| PASS Trying to abort() via PaymentRequest is not possible. | |
| PASS It's possible to retry() multiple times and eventually complete(). After complete(), however, retry() rejects with an InvalidStateError. | |
| PASS The user aborting retrying a payment causes the retryPromise to reject with AbortError. Aborting a payment is causes it complete. | |
| PASS When retrying, the user is shown error fields to fix. | |
| PASS When "abort the update" occurs because of an update error, the `retryPromise` is rejected and response.[[complete]] becomes true. | |
| PASS Calling retry() multiple times is always a new object. | |
| PASS When retrying without errors, the user is shown an `unknown` error. | |
| PASS response.details should be updated after the user accepts a retry. | |
