Q1Domain Verified
In the context of asynchronous testing with Mocha, what is the primary purpose of a `done` callback when testing asynchronous operations?
To introduce artificial delays for performance testing of asynchronous code.
To explicitly mark the successful completion of an asynchronous operation, preventing Mocha from timing out.
To signal the end of a synchronous test case, allowing Mocha to proceed to the next test.
To capture console logs generated during the asynchronous operation for debugging purposes.
Q2Domain Verified
When dealing with promises in Mocha, which of the following is the most robust and recommended way to handle asynchronous assertions?
Using `setTimeout` to wait for the promise to resolve before asserting.
Using `async/await` syntax to pause execution until the promise resolves.
Manually checking `promise.isResolved()` within a loop.
Returning the promise directly from the test function.
Q3Domain Verified
Consider an asynchronous test that involves multiple sequential asynchronous operations, each returning a promise. Which Mocha testing pattern best encapsulates this scenario for clear and maintainable tests?
Chaining `then` calls without `async/await`.
Using `async/await` with sequential `await` statements.
Employing `Promise.all` for all operations, even if they are dependent.
Nested `then` callbacks.
