## REST API call to plugin

To verify the custom token presented in the `AssumeRoleWithCustomToken` API, MinIO makes a POST request to the configured identity management plugin endpoint and expects a response with some details as shown below:

Being able to use asynchronous functions in your tests could be useful, for example, when you're querying your database asynchronously. Imagine you want to test sending requests to your FastAPI application and then verify that your backend successfully wrote the correct data in the database, while using an async database library.

Let's look at how we can make that work.

## pytest.mark.anyio { #pytest-mark-anyio }

    ByteSource source = out.asByteSource();

    out.write(data);
    assertThat(source.read()).isEqualTo(data);

    out.close();
    assertThrows(IOException.class, () -> out.write(42));

    // Verify that write had no effect
    assertThat(source.read()).isEqualTo(data);
    out.reset();
  }

  public void testReset() throws Exception {
    byte[] data = newPreFilledByteArray(100);

                throw new AssertionError("Should not have been invoked again");
            }
          }
        };

    assertTrue(iter.hasNext());
    assertEquals(0, (int) iter.next());

    // verify idempotence of hasNext()
    assertTrue(iter.hasNext());
    assertTrue(iter.hasNext());
    assertTrue(iter.hasNext());
    assertEquals(1, (int) iter.next());

    assertFalse(iter.hasNext());

 * In this example the HTTP client already knows and trusts the last certificate, "Entrust Root
 * Certification Authority - G2". That certificate is used to verify the signature of the
 * intermediate certificate, "Entrust Certification Authority - L1M". The intermediate certificate
 * is used to verify the signature of the "www.squareup.com" certificate.

 * This roles are reversed for client authentication. In that case the client has a private key and
