What is the difference between asynchronous and synchronous tests?

What is the difference between asynchronous and synchronous tests?

Synchronous tests run sequentially, waiting for each to complete before starting the next. Asynchronous tests can run concurrently, allowing multiple tests to execute at the same time.

Can you give me an example of each?

Sure! In a synchronous test, if you have a function that fetches data, it will wait for the data to return before moving on. In an asynchronous test, it can start fetching data and move on to other tasks while waiting for the data to return.

What are the advantages of using asynchronous tests?

Asynchronous tests can significantly reduce the overall testing time, especially for I/O-bound operations, as they allow multiple operations to run in parallel.

Are there any downsides to asynchronous testing?

Yes, asynchronous tests can be more complex to write and debug, as you need to manage the timing and ensure that tests do not interfere with each other.
