Good bug reports include a failing test! Writing a test helps you to isolate and describe the problem, and it helps us to fix it fast. Bug reports without a failing test or reproduction steps are likely to be closed.

Here’s an example test to get you started.

      writerClosed = true
    }
  }

  @Throws(IOException::class)
  private fun writeControlFrame(
    opcode: Int,
    payload: ByteString,
  ) {
    if (writerClosed) throw IOException("closed")

    val length = payload.size
    require(length <= PAYLOAD_BYTE_MAX) {
      "Payload size must be less than or equal to $PAYLOAD_BYTE_MAX"
    }

    val b0 = B0_FLAG_FIN or opcode

        assertThrows(SmbUnsupportedOperationException.class, sut::watch);
        verify(tree, times(1)).close();
    }

    // SMB1 path: on error code 0x10B the handle should be marked closed
    @Test
    @DisplayName("watch() SMB1 marks handle closed on error 0x10B")
    void watch_smb1_marksClosed_onError10B() throws Exception {
        NotifyResponse resp = mock(NotifyResponse.class);
        when(resp.isReceived()).thenReturn(true);
