<h2>
Manual Tests for PaymentResponse.complete() - Please run in order!
</h2>
<p>
Click on each button in sequence from top to bottom without refreshing the page.
Each button will bring up the Payment Request UI window.
</p>
<p>
When presented with the payment sheet, use any credit card select to "Pay".
Also confirm any prompts that come up.
</p>
<ol>
<li>
<button onclick="runManualTest({completeWith: 'success'}, this)">
If the value of the internal slot [[completeCalled]] is true,
reject promise with an "InvalidStateError" DOMException.
</button>
</li>
<li>
<button onclick="runManualTest({completeWith: undefined}, this)">
Passing no argument defaults to "unknown",
eventually closing the sheet and doesn't throw.
</button>
</li>
<li>
<button onclick="runManualTest({completeWith: 'success'}, this)">
Passing "success" eventually closes the sheet and doesn't throw.

Passing "fail" eventually closes the sheet and doesn't throw.
