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`:

```Python hl_lines="6-9"

	}
	for i, testCase := range testCases {
		r := NewSkipReader(testCase.src, testCase.skipLen)
		b, err := io.ReadAll(r)
		if err != nil {
			t.Errorf("Case %d: Unexpected err %v", i, err)
		}
		if string(b) != testCase.expected {
			t.Errorf("Case %d: Got wrong result: %v", i, string(b))
		}
	}
}

func TestSameFile(t *testing.T) {
	f, err := os.CreateTemp("", "")
	if err != nil {

		for _, resource := range response.Resources {
			eString := string(resource.Value)
			switch {
			case strings.Contains(eString, "You must provide a proxyID in the query string"):
				return nil, fmt.Errorf(" You must provide a proxyID in the query string, e.g. [%s]",
					"edsz?proxyID=istio-ingressgateway")

			case strings.Contains(eString, "404 page not found"):

Now let's jump to the fun stuff. 🎉

## Add `Query` to `Annotated` in the `q` parameter

Now that we have this `Annotated` where we can put more information (in this case some additional validation), add `Query` inside of `Annotated`, and set the parameter `max_length` to `50`:

	for i, tc := range evalCases {
		res, err := evalSQLSubstring(tc.s, tc.startIdx, tc.length)
		if res != tc.resExpected || err != tc.errExpected {
			t.Errorf("Eval Case %d failed: %v %v", i, res, err)
		}
	}

				}
				fields++

			r.Close()
			if err != io.EOF {
				t.Fatalf("Case %d failed with %s", i, err)

				t.Errorf("Case %d failed: expected %#v, got result %#v", i, c.wantColumns, r.columnNames)

## Deployment Strategies

There are several ways to do it depending on your specific use case and the tools that you use.

You could **deploy a server** yourself using a combination of tools, you could use a **cloud service** that does part of the work for you, or other possible options.

On Windows, [Current] has been made considerably faster when
the current user is joined to a slow domain, which is the
usual case for many corporate users. The new implementation
performance is now in the order of milliseconds, compared to
the previous implementation which could take several seconds,
