You do not need an input element for t.keyPress to work.
Edit:
Here is a simple test using t.pressKey('.'):
import { Selector } from 'testcafe';
fixture`Press key`
.page`./index.html`;
test('Press dot', async t => {
await t
.pressKey('.')
.expect(Selector('p').textContent).eql('Dot is pressed');
});
index.html
<html>
<body>
<p id='paragraph'>Press key</p>
<script>
document.addEventListener('keydown', event => {
if (event.key === '.')
document.getElementById('paragraph').textContent = 'Dot is pressed';
});
</script>
</body>
</html>
So it doesn’t work when I try to await t.keyPress(‘.’)
I updated the answer with a working test. Could you share more details about your scenario? A simple example illustrating the issue would be appreciated.
