What are the differences between async and sync in TestCafe?

What are the differences between async and sync in TestCafe?

In TestCafe, async functions allow you to perform tasks without blocking the execution of other code, while sync functions run sequentially, blocking until the current task is complete.

Can you give me an example of when to use async?

Sure! Use async when you need to wait for a network request or a database operation, allowing other tests to run in the meantime.

What about sync? When should I use that?

Sync is useful for simple tasks that don't require waiting, like setting up test data or performing straightforward assertions.

Are there any performance implications between the two?

Yes, async can improve performance by allowing parallel execution, while sync can slow down tests if they involve long-running operations.
