Create a function to be run as the background task.

It is just a standard function that can receive parameters.

It can be an `async def` or normal `def` function, **FastAPI** will know how to handle it correctly.

In this case, the task function will write to a file (simulating sending an email).

And as the write operation doesn't use `async` and `await`, we define the function with normal `def`:

        int bytesRead = response.readDataWireFormat(buffer, 0, buffer.length);

        assertTrue(bytesRead > 0);
        assertNotNull(response.getInfo());

        // Verify the correct type was created
        if (infoLevel == FileInformation.FILE_BASIC_INFO) {
            assertTrue(response.getInfo() instanceof FileBasicInfo);
        } else if (infoLevel == FileInformation.FILE_STANDARD_INFO) {

6.  For the mainline flavor, we test the libraries using OpenJDK 8, 11, and 17
    on Linux, with some additional testing on newer JDKs and on Windows. Some
    features, especially in `com.google.common.io`, may not work correctly in
    non-Linux environments. For the Android flavor, our unit tests also run on
    API level 23 (Marshmallow).
