SYNOPSIS

       dbus-test-tool black-hole [--session | --system] [--name=NAME] [--no-read]

       dbus-test-tool echo [--session | --system] [--name=NAME] [--sleep-ms=MS]

       dbus-test-tool spam [--session | --system] [--dest=NAME] [--count=N] [--flood]
                      [--ignore-errors] [--messages-per-conn=N] [--no-reply] [--queue=N]
                      [--seed=SEED] [--string | --bytes | --empty] [--payload=S | --stdin |
                      --message-stdin | --random-size]

DESCRIPTION

       dbus-test-tool is a multi-purpose tool for debugging and profiling D-Bus.

       dbus-test-tool black-hole connects to D-Bus, optionally requests a name, then does not
       reply to messages. It normally reads and discards messages from its D-Bus socket, but can
       be configured to sleep forever without reading.

       dbus-test-tool echo connects to D-Bus, optionally requests a name, then sends back an
       empty reply to every method call, after an optional delay.

       dbus-test-tool spam connects to D-Bus and makes repeated method calls, normally named
       com.example.Spam.

OPTIONS

   Common options
       --session
           Connect to the session bus. This is the default.

       --system
           Connect to the system bus.

   black-hole mode
       --name=NAME
           Before proceeding, request ownership of the well-known bus name NAME, for example
           com.example.NoReply. By default, no name is requested, and the tool can only be
           addressed by a unique bus name such as :1.23.

       --no-read
           Do not read from the D-Bus socket.

   echo mode
       --name=NAME
           Before proceeding, request ownership of the well-known bus name NAME, for example
           com.example.Echo. By default, no name is requested, and the tool can only be addressed
           by a unique bus name such as :1.23.

       --sleep-ms=MS
           Block for MS milliseconds before replying to a method call.

   spam mode
       --dest=NAME
           Send method calls to the well-known or unique bus name NAME. The default is the
           dbus-daemon, org.freedesktop.DBus.

       --count=N
           Send N method calls in total. The default is 1.

       --queue=N
           Send N method calls before waiting for any replies, then send one new call per reply
           received, keeping N method calls "in flight" at all times until the number of messages
           specified with the --count option have been sent. The default is 1, unless --flood is
           used.

       --flood
           Send all messages without waiting for a reply, equivalent to --queue with an
           arbitrarily large N.

       --no-reply
           Set the "no reply desired" flag on the messages. This implies --flood, since it
           disables the replies that would be used for a finite --queue length.

       --messages-per-conn=N
           If given, send N method calls on the same connection, then disconnect and reconnect.
           The default is to use the same connection for all method calls.

       --string
           The payload of each message is a UTF-8 string. This is the default. The actual string
           used is given by the --payload or --stdin option, defaulting to "hello, world!".

       --bytes
           The payload of each message is a byte-array. The actual bytes used are given by the
           --payload or --stdin option, defaulting to the ASCII encoding of "hello, world!".

       --empty
           The messages have no payload.

       --payload=S
           Use S as the --string or --bytes in the messages. The default is "hello, world!".

       --stdin
           Read from standard input until end-of-file is reached, and use that as the --string or
           --bytes in the messages.

       --message-stdin
           Read a complete binary D-Bus method call message from standard input, and use that for
           each method call.

       --random-size
           Read whitespace-separated ASCII decimal numbers from standard input, choose one at
           random for each message, and send a message whose payload is a string of that length.

       --seed=SEED
           Use SEED as the seed for the pseudorandom number generator, to have somewhat
           repeatable sequences of random messages.
