Now, there are some cases where you might want to have the **same schema for input and output**.

Probably the main use case for this is if you already have some autogenerated client code/SDKs and you don't want to update all the autogenerated client code/SDKs yet, you probably will want to do it at some point, but maybe not right now.

== How to write good tests?

=== Base classes for test cases

There are multiple base classes for tests:

* **`ESTestCase`**: The base class of all tests. It is typically extended
  directly by unit tests.
* **`ESSingleNodeTestCase`**: This test case sets up a cluster that has a
  single node.
* **`ESIntegTestCase`**: An integration test case that creates a cluster that
  might have multiple nodes.

Pour OAuth2, ce ne sont que des chaînes.

///

## Vue d’ensemble { #global-view }

Voyons d’abord rapidement les parties qui changent par rapport aux exemples du **Tutoriel - Guide utilisateur** pour [OAuth2 avec mot de passe (et hachage), Bearer avec jetons JWT](../../tutorial/security/oauth2-jwt.md). Cette fois, en utilisant des scopes OAuth2 :

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

Those parameters are what **FastAPI** will use to "solve" the dependency.

In both cases, it will have:

* An optional `q` query parameter that is a `str`.
* A `skip` query parameter that is an `int`, with a default of `0`.
* A `limit` query parameter that is an `int`, with a default of `100`.

In both cases the data will be converted, validated, documented on the OpenAPI schema, etc.

## Use it { #use-it }

/// info

A "bearer" token is not the only option.

But it's the best one for our use case.

And it might be the best for most use cases, unless you are an OAuth2 expert and know exactly why there's another option that better suits your needs.

In that case, **FastAPI** also provides you with the tools to build it.

///

func Index(s, sep []byte) int {
	n := len(sep)
	switch {
	case n == 0:
		return 0
	case n == 1:
		return IndexByte(s, sep[0])
	case n == len(s):
		if Equal(sep, s) {
			return 0
		}
		return -1
	case n > len(s):
		return -1
	case n <= bytealg.MaxLen:
		// Use brute force when s and sep both are small
		if len(s) <= bytealg.MaxBruteForce {

		secretKey          string
		expectedRespStatus int
	}{
		// Test case - 1.
		// Validate a good case request succeeds.
		{
			bucketName:         bucketName,
			accessKey:          credentials.AccessKey,
			secretKey:          credentials.SecretKey,
			expectedRespStatus: http.StatusOK,
		},
		// Test case - 2.
		// Test case with invalid accessKey to produce and validate Signature Mismatch error.

### Certificate Renewal { #certificate-renewal }

At some point in the future, each certificate would **expire** (about 3 months after acquiring it).

And then, there would be another program (in some cases it's another program, in some cases it could be the same TLS Termination Proxy) that would talk to Let's Encrypt, and renew the certificate(s).

        void testGetRootCause() {
            Exception rootCause = new IllegalStateException("Test root cause");
            TransportException exception = new TransportException("Message", rootCause);

            assertEquals(rootCause, exception.getRootCause());
        }

        @Test
        @DisplayName("Should return null when no root cause")
        void testGetRootCauseWhenNull() {
