NAME dbus-test-tool - D-Bus traffic generator and test tool
SYNOPSIS dbus-test-tool black-hole [--session | --system] [--name=NAME] [--no-read] dbus-test-tool echo [--session | --system] [--name=NAME] [--sleep=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 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.
