# Testing WebSockets { #testing-websockets }

You can use the same `TestClient` to test WebSockets.

For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note

For more details, check Starlette's documentation for [testing WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions).

        // Given - Use same key for both encryption and decryption in test
        // In production, client would use clientEncKey/serverDecKey and server would use serverEncKey/clientDecKey
        Smb2EncryptionContext context = new Smb2EncryptionContext(EncryptionNegotiateContext.CIPHER_AES128_GCM, DialectVersion.SMB311,
                testEncryptionKey, testEncryptionKey); // Use same key for test

SAM Conversions
---------------

When you use Java APIs from Kotlin you can operate on Java interfaces as if they were Kotlin
lambdas. The [feature][java_sams] is available for interfaces that define a Single Abstract Method
(SAM).

But when you use Kotlin APIs from Kotlin there’s no automatic conversion. Code that used SAM lambdas
with OkHttp 3.x: must use `object :` with OkHttp 4.x:

import org.jspecify.annotations.Nullable;

/**
 * Executor ensuring that all Runnables submitted are executed in order, using the provided
 * Executor, and sequentially such that no two will ever be running at the same time.
 *
 * <p>Tasks submitted to {@link #execute(Runnable)} are executed in FIFO order.
 *
 * <p>The execution of tasks is done by one thread as long as there are tasks left in the queue.

            long timeDiffLength = measureEqualsTime(auth1, auth2, TIMING_ITERATIONS);

            // Create same length passwords for comparison
            char[] password3 = "short".toCharArray();
            char[] password4 = "shore".toCharArray(); // Same length, different content

            NtlmPasswordAuthenticator auth3 = new NtlmPasswordAuthenticator("domain", "user", new String(password3));
