## Deprecate a *path operation* { #deprecate-a-path-operation }

If you need to mark a *path operation* as <abbr title="obsolete, recommended not to use it">deprecated</abbr>, but without removing it, pass the parameter `deprecated`:

{* ../../docs_src/path_operation_configuration/tutorial006.py hl[16] *}

It will be clearly marked as deprecated in the interactive docs:

     * it is supplied by the user at runtime.
     *
     * @return the password
     * @deprecated Use getPasswordAsCharArray() for better security
     */
    @Deprecated
    public String getPassword() {
        checkNotClosed();
        log.warn("getPassword() is deprecated and insecure. Use getPasswordAsCharArray() instead.");
        return this.password != null ? new String(this.password) : null;

## Changes by Kind

### Deprecation

- Apimachinery: Deprecated `MessageCountMap` and `CreateAggregateFromMessageCountMap`. ([#132376](https://github.com/kubernetes/kubernetes/pull/132376), [@tico88612](https://github.com/tico88612))

     *
     * This was deprecated in OkHttp 4.0 in favor of the [level] val. In OkHttp 4.3 it is
     * un-deprecated because Java callers can't chain when assigning Kotlin vals. (The getter remains
     * deprecated).
     */
    fun setLevel(level: Level) =
      apply {
        this.level = level
      }

    @JvmName("-deprecated_level")
    @Deprecated(
      message = "moved to var",

    }

    public void test_class_has_proper_annotations() {
        // Verify the class doesn't have any inappropriate annotations
        assertFalse("Class should not be deprecated", HotThreadMonitorTarget.class.isAnnotationPresent(Deprecated.class));
    }

Before Pydantic version 2 and before FastAPI 0.100.0, the parameter was called `regex` instead of `pattern`, but it's now deprecated.

You could still see some code using it:

//// tab | Pydantic v1

{* ../../docs_src/query_params_str_validations/tutorial004_regex_an_py310.py hl[11] *}

////

But know that this is deprecated and it should be updated to use the new parameter `pattern`. 🤓

## Default values { #default-values }

You can read more details about the ["Running lifespan in tests in the official Starlette documentation site."](https://www.starlette.io/lifespan/#running-lifespan-in-tests)

For the deprecated `startup` and `shutdown` events, you can use the `TestClient` as follows:

    }

    public void test_class_has_proper_annotations() {
        // Verify the class doesn't have any inappropriate annotations
        assertFalse("Class should not be deprecated", SystemMonitorTarget.class.isAnnotationPresent(Deprecated.class));
    }

    public void test_inherited_methods_from_monitor_target() throws Exception {
        // Test that inherited methods are accessible
        Method appendMethod = null;

{* ../../docs_src/events/tutorial003.py hl[22] *}
