### Async Context Manager { #async-context-manager }

If you check, the function is decorated with an `@asynccontextmanager`.

That converts the function into something called an "**async context manager**".

A **context manager** in Python is something that you can use in a `with` statement, for example, `open()` can be used as a context manager:

         * Verifies that the close method can be called without throwing an exception.
         * @throws CIFSException if an error occurs during close.
         */
        @Test
        public void testClose() throws CIFSException {
            assertDoesNotThrow(() -> smbPipeHandle.close(), "close() should not throw an exception on a mock object.");
            // Verify that the close method was called
            Mockito.verify(smbPipeHandle).close();

        InetAddress addr = mock(InetAddress.class);
        when(addr.getHostName()).thenReturn(hostname);
        UniAddress ua = new UniAddress(addr);
        // Act
        String called = ua.firstCalledName();
        // Assert
        assertEquals(expectedPrefix, called, "firstCalledName should return uppercase prefix or SMBSERVER_NAME");
    }

    void nextCalledNameWithNbtAddressReturnsDelegateValue() {

Interceptors can be chained. Suppose you have both a compressing interceptor and a checksumming interceptor: you'll need to decide whether data is compressed and then checksummed, or checksummed and then compressed. OkHttp uses lists to track interceptors, and interceptors are called in order.

        this.macAddress = macAddress;
        isDataFromNodeStatus = true;

     * @return the first called name to try

        calledName = hostName.name;

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.

Even if your **FastAPI** application uses normal `def` functions instead of `async def`, it is still an `async` application underneath.
