Is it possible to declare an async method without await inside? Will such code compile?

Yes, in languages that support async/await (such as C# or JavaScript), you can declare a method as async without using await inside. Such code will compile and work.

However, the compiler usually issues a warning that an async method does not contain await, which may indicate that the method runs synchronously and async is unnecessary.

Example in C#:

public async Task<int> GetNumberAsync()
{
    return 42; // No await
}

This method returns a completed Task<int>, but does not await anything asynchronously.

In QA Automation, this can be useful if the interface requires async, but the implementation is currently synchronous.
