What are the best practices for async assertions in TestCafe?

When using async assertions in TestCafe, it's important to ensure that your tests are reliable and maintainable. Here are some best practices:

1. Use the await keyword to handle promises properly.
2. Keep your assertions clear and concise.
3. Avoid using too many nested async calls to maintain readability.
4. Use TestCafe's built-in assertion methods for consistency.

Can you give an example of an async assertion?

Sure! Here's a simple example:

import { Selector } from 'testcafe';

fixture `My Fixture`
    .page `http://example.com`;

test('Async assertion example', async t => {
    const element = Selector('#my-element');
    await t.expect(element.visible).ok('Element should be visible');
});

What should I avoid when writing async assertions?

You should avoid:

1. Overcomplicating your assertions with too many conditions.
2. Ignoring the order of async operations, which can lead to flaky tests.
3. Using hard-coded timeouts instead of relying on TestCafe's built-in waiting mechanisms.

How can I debug async assertions in TestCafe?

To debug async assertions, you can:

1. Use t.debug() to pause the test and inspect the state.
2. Add logging statements to track the flow of your async operations.
3. Utilize the TestCafe's built-in error messages to understand what went wrong.
