<h2>updateWith() method</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 the payment sheet is shown, select a different shipping address once. Then pay.
</p>
<ol>
<li id="test-0">
<button onclick="testImmediateUpdate(this);">
updateWith() must be called immediately, otherwise must throw an InvalidStateError.
</button>
</li>
<li id="test-1">
<button onclick="testSubsequentUpdateWithCalls(this);">
Once the event has performed an update, subsequent calls to updateWith() must throw InvalidStateError.
</button>
</li>
<li id="test-2">
<button onclick="testRecycleEvents(this);">
Recycling events must not be possible.
</button> When the payment sheet is shown, select a different shipping address once, then change shipping option once. Then pay.
