+What is tbot ?
+==============
+
+tbot is a tool for executing testcases on boards.
+Source code found on [1]
+Based on DUTS [2]
+written in python
+
+Basic Ideas of tbot
+===================
+(see also the figure:
+https://github.com/hsdenx/tbot/blob/master/doc/tbot_structure.png )
+
+- Virtual laboratory (VL)
+ VL is the basic environment that groups:
+ - [a number of] boards - target devices on which tbot executes testcases.
+ - one Lab PC
+
+- Test case (TC):
+ A piece of python code, which uses the tbot class from [1].
+ Tbot provides functions for sending shell commands and parsing the
+ shell commands output.
+ Tbot waits endless for a shell commands end (detected through reading
+ the consoles prompt).
+ A TC can also call other TC-es.
+
+ remark:
+ Tbot not really waits endless, for a shell commands end, instead
+ tbot starts a watchdog in the background, and if it triggers, tbot
+ ends the TC as failed. In the tbot beginning there was a lot of
+ timeouts / retry cases, but it turned out, that waiting endless
+ is robust and easy ...
+
+- Host PC (where tbot runs, currently only linux host tested)
+ must not a powerful machine (For example [3], I use a
+ raspberry pi for running tbot and buildbot)
+
+- Lab PC:
+ - Host PC connects through ssh to the Lab PC
+ -> so it is possible to test boards, which
+ are not at the same place as the Host PC.
+ (Lab PC and Host PC can be the same of course)
+ -> maybe we can setup a Testsystem, which does nightly
+ U-Boot/Linux builds and test from current mainline U-Boot
+ on boards wherever they are accessible.
+
+ - necessary tasks a Lab PC must deliver:
+ - connect to boards console through a shell command.
+ - power on/off boards through a shell command
+ - detect the current power state of a board through
+ a shell command
+
+ - optional tasks:
+ - tftp server (for example loading images)
+ - nfs server (used as rootfs for linux kernels)
+ - Internet access for example for downloading
+ U-Boot source with git.
+ - toolchains installed for compiling source code
+
+ -> a linux machine is preffered.
+
+ - currently only Lab PC with an installed linux supported/tested.
+
+- Boards(s):
+ the boards on which shell commands are executed.
+
+- Board state:
+ equals to the software, the board is currently running.
+
+ Currently tbot supports 2 board states:
+ - "u-boot", if the board is running U-Boot
+ - "linux", if the board is running a linux kernel
+
+ It should be easy to add other board states to tbot, see
+ https://github.com/hsdenx/tbot/tree/master/src/lab_api/state_[u-boot/linux].py
+
+ A board state is detected through analysing the boards
+ shell prompt. In linux, tbot sets a special tbot prompt,
+ in U-Boot the prompt is static, and configurable in tbot through
+ a board config file.
+
+ A TC can say in which board state it want to send shell commands.
+ Tbot tries to detect the current board state, if board is not in
+ the requested board state, tbot tries to switch into the correct
+ state. If this fails, the TC fails.
+
+ It is possible to switch in a single TC between board states.
+
+- tbot cmdline parameters:
+
+$ python2.7 src/common/tbot.py --help
+Usage: tbot.py [options]
+
+Options:
+ -h, --help show this help message and exit
+ -c CFGFILE, --cfgfile=CFGFILE
+ the tbot common configfilename
+ -l LOGFILE, --logfile=LOGFILE
+ the tbot logfilename, if default, tbot creates a
+ defaultnamelogfile
+ -t TC, --testcase=TC the testcase which should be run
+ -v, --verbose be verbose, print all read/write to stdout
+ -w WORKDIR, --workdir=WORKDIR
+ set workdir, default os.getcwd()
+$
+
+tbot needs the following files for proper execution:
+
+ - tbot board configuration file (option -c):
+ A board configuration file contains settings tbot needs to
+ connect to the Lab PC and board specific variable settings
+ for testcases.
+
+ - name of the logfile tbot creates (option -l)
+ defaultname: 'log/' + now.strftime("%Y-%m-%d-%H-%M") + '.log'
+
+ - tbots working directory (option -w)
+
+ - the testcasename tbot executes (option -t)
+
+You are interested and want to use tbot?
+If so, please read on the file:
+tools/tbot/README.install
+
+If not read [3] ;-)

+[2] http://www.denx.de/wiki/DUTS/DUTSDocs
+[3] automated Testsetup with buildbot and tbot doing cyclic tests
+ (buildbot used for starting tbot TC and web presentation of the
+ results, all testing done through tbot):
+ http://xeidos.ddns.net/buildbot/tgrid
+ Host PC in Letkes/hungary
+ VL in munich/germany
+
+ Fancy things are done here, for example:
+ - http://xeidos.ddns.net/buildbot/builders/smartweb_dfu/builds/43/steps/shell/logs/tbotlog
+ (I try to cleanup the logfile soon, so it is not so filled with crap ;-)
+ A first step see here:
+ http://xeidos.ddns.net/buildbot/builders/smartweb_dfu/builds/45/steps/shell/logs/tbotlog
+ (same TC now with the new loglevel = 'CON' ... not yet perfect)
+ Executed steps:
+ - clone u-boot.git
+ - set toolchain
+ - get a list of patchwork patches from my U-Boots ToDo list
+ - download all of them, and check them with checkpatch
+ and apply them to u-boot.git
+ - compile U-Boot for the smartweb board
+ - install the resulting images on the smartweb board
+ - boot U-boot
+ - test DFU
+ - more TC should be added here for testing U-Boot
+
+ - automatic "git bisect"
+ https://github.com/hsdenx/tbot/blob/master/src/tc/tc_board_git_bisect.py
+ http://xeidos.ddns.net/buildbot/builders/tqm5200s/builds/3/steps/shell/logs/tbotlog
+
+ If a current U-Boot image not works on the tqm5200 board
+ this TC can be started. It starts a "git bisect" session,
+ and compiles for each step U-Boot, install it on the tqm5200
+ board, and tests if U-Boot works !
+
+ At the end, it detects the commit, which breaks the board
+
+ This TC is not dependend on U-Boot nor on a special board. It
+ needs only 3 variables:
+ tb.board_git_bisect_get_source_tc: TC which gets the source tree, in which
+ "git bisect" should be executed
+ tb.board_git_bisect_call_tc: TC which gets called every "git bisect" step,
+ which executes commands for detecting if current source code is OK or not.
+ This could be a TC which compiles U-Boot, install it on the board and
+ executes TC on the new booted U-Boot image. ! Board maybe gets borken,
+ as not all U-Boot images work, so you must have a TC which install U-Boot
+ image for example through a debugger.
+ tb.board_git_bisect_good_commit: last nown good commit id

+ToDo list for tbot
+==================
+
+please look also into the tbot ToDo list.
+https://github.com/hsdenx/tbot/blob/master/ToDo
+
+- cleanup tbot code:
+ - remove all retry / timeout pieces of code
+ - clean up tbot function names, as I am not good in
+ giving function a understandable name ;-)
+ - as I am not a python programmer, cleanup whole tbot code
+
+- introduce a "layering" like yocto do, so U-Boot TC can integrated
+ into U-Boot source code.
+
+ Proposal:
+ introduce subdirs in "src/tc"
+
+ lab: all lab specific stuff
+ lab/common: common lab stuff (for example ssh handling)
+ lab/ssh_std: ssh_std specific stuff
+
+ u-boot: all u-boot tests
+ u-boot/common: common u-boot tc
+ u-boot/duts: DUTS tc
+ u-boot-dxr2: all u-boot dxr2 board specific tc
+
+ board: board tc
+ board/common: common board tc
+ board/dxr2: all tc for dxr2 board
+
+ linux: all linux tc
+ linux/common: common linux tc
+ linux/dxr2
+
+ - move U-Boot special TC to U-Boot source
+ -> need a mechanism in tbot, how it gets automatically for example
+ U-Boot TC from U-Boot source...
+ -> add a consistency checker
+
+- simplify tbot log output (seperate a lot of output which is currently
+ in INFO logging level, to another logging level)
+ started (new loglevel "CON", whih prints read/write from console only), see:
+ https://github.com/hsdenx/tbot/commit/b4ab2567ad8c19ad53f785203159d3c8465a21c6
+ - make the timestamp configurable
+
+- Open more than 2 filehandles ?
+ Do we need for more complex TC more than 2 filehandles?
+
+- Find a way to document all TC and document all variables they use in an
+ automated way.
+
+- write a lot of more TC
+
+- get U-Boot configuration settings from current U-Boot code and use
+ them in U-Boot TC-es

+
+write a new testcase
+=====================
+
+A TC is written in python, so you can use python as usual. For accessing
+the boards console, use functions from the tbotlib, therefore
+
+First import the tbotlib with the line:
+
+ from tbotlib import tbot
+
+If your TC uses variables, please add a line which adds them to
+the log file (for debugging purposes):
+
+ logging.info("args: %s ...", tb.varname, ...)
+
+Say tbot, for which board state your TC is valid with:
+
+ tb.set_board_state("u-boot")
+
+Then you are ready ... and you can use the tbotlib funtions
+for writting/reading to the boards console.
+
+Big fat warning:
+
+A TC must worry about to end only if a board has finished the shell
+command!
+
+Not following this rule, will end in unpredictable behaviour.
+
+(hopefully) useful tbotlib functions
+====================================
+- set the board state, you want to test
+ tb.set_board_state(state)
+ states are: "u-boot" or "linux"
+ If tbot could not set the board state, tbot ends with failure.
+
+- write a command to the boards console:
+ tb.eof_write_con(command):
+ write the command to the boards console. If this
+ fails, tbot ends with failure
+
+- write a command to boards console and wait for prompt:
+ tb.eof_write_cmd(fd, command):
+ fd: filedescriptor which is used, use tb.channel_con for boards console
+ command: command which is written to fd
+
+ Wait endless for board prompt
+
+- write a list of commands to boards console:
+ tb.eof_write_cmd_list(fd, cmdlist):
+ fd: filedescriptor which is used, use tb.channel_con for boards console
+ cmdlist: python list of commandstrings which is written to fd
+
+- wait for boards prompt:
+ tb.eof_read_end_state_con(retry):
+ retry: deprecated, not used anymore, cleanup needed here...
+ tbot waits endless for the boards prompt
+
+- write a command, wait for prompt and check, if a string is read
+ tb.write_cmd_check(fd, cmd, string):
+ fd: filedescriptor which is used, use tb.channel_con for boards console
+ cmd: command, which is send to fd
+ string: string which should be read from fd
+
+ return value:
+ True, if string is read and tbot got back boards prompt
+ False, else
+
+ tb.eof_write_cmd_check(fd, cmd, string):
+ same as tb.write_cmd_check(fd, cmd, string) except, that tbot
+ ends immediately with Failure, if string is not read.
+
+- read until prompt and search strings:
+ tb.readline_and_search_strings(fd, strings):
+ fd: filedescriptor which is used, use tb.channel_con for boards console
+ strings: python list of strings, which can be read
+ If one of this strings is read, this function return the index, which
+ string is read. This function shoud be called in a while loop,
+ until this function returns 'prompt'
+
+- read a line from filedescriptor:
+ not recommended to use, as the TC must check, if tprompt is read for every
+ readen line. Also TC must ensure, that it ends only, if prompt is read.
+ tb.read_line(fd, retry)
+ fd: filedescriptor which is used, use tb.channel_con for boards console
+ retry: retry of trying to reead a line
+
+ return values:
+ True, if a line is read. Readen line in tb.buf[fd]
+ False, if something read, but not a complete line
+ None, if nothing is read
+
+ check if string contains prompt with:
+ tb.is_end_fd(fd, string)
+ fd: filedescriptor which is used, use tb.channel_con for boards console
+ string: buffer, in which a prompt gets searched.
+
+- calling other TC:
+ eof_call_tc(name):
+ call another TC from "src/tc"
+ if the called TC fails with failure, tbot ends with failure
+
+ call_tc(name):
+ call another TC from "src/tc"
+ if the TC which call_tc calls fails, call_tc() returns False, else True
+
+There are more functions, but for writting TC this should be enough. But
+its software, so new useful functions can always pop up.

+
+install tbot on your PC (linux only tested):
+============================================
+
+- get the source code:
+
+$ git clone https://github.com/hsdenx/tbot.git
+[...]
+$
+
+ cd into the tbot directory.
+
+- you need the for running tbot the python paramiko module, see:
+ http://www.paramiko.org/installing.html
+
+ paramiko is used for handling ssh sessions, and open filedescriptors
+ on a ssh connection. Tbot open a ssh connection to a "lab PC" and
+ opens on that connection 2 filehandles, one for control functions
+ and one for the connection to the boards console. May it is worth
+ to think about to open more filehandles and use them in tbot, but
+ thats a point in the Todo list ...
+
+ See [1] for more infos about tbot principles.
+
+- prepare a directory for storing the logfiles
+ and pass it with the commandline option "-l"
+ to tbot. Default is the directory "log" in the tbot
+ root (don;t forget to create it, if you want to use it)
+
+- If your VL is not yet in tbot source, integrate it
+ (This task has only to be done once for your VL):
+
+ A VL has, as described in [2] "necessary tasks for a Lab PC" explained,
+ 3 tasks:
+
+ a) power on/off the board
+ b) get power state of the board
+ c) connect to the boards console
+
+ As tbot sends only shell commands (also to the Lab PC)
+ this tasks must be executable through shell commands on your
+ Lab PC:
+
+ Task a) power on/off board:
+ default TC for this task is:
+ https://github.com/hsdenx/tbot/blob/master/src/tc/tc_lab_denx_power.py
+
+ - now copy this file to for example
+ cp src/tc/tc_lab_denx_power.py src/tc/tc_lab_denx_power_XXX.py
+ (replace XXX to a proper value)
+ and adapt the "remote_power" command from the denx lab to your needs.
+
+ As this TC powers on the board for all your boards in your VL,
+ you can differ between the boards through the tbot class
+ variable "tb.boardlabpowername" (which is in the default case the
+ same as "tb.boardname"), but you may need to name the power target
+ with an other name than boardname, so you can configure this case.
+ The power state "tb.power_state" which the TC has to set
+ is "on" for power on, or "off" for power off.
+
+ If switching on the power is successful, call "tb.end_tc(True)"
+ else "tb.end_tc(False)"
+
+ - set in your board config file:
+ self.tc_lab_denx_power_tc = 'tc_lab_denx_power_XXX.py'
+
+ Task b) power on/off board:
+ default TC for this task is:
+ https://github.com/hsdenx/tbot/blob/master/src/tc/tc_lab_denx_get_power_state.py
+
+ - now copy this file to for example
+ (replace XXX to a proper value)
+ cp src/tc/tc_lab_denx_get_power_state.py src/tc/tc_lab_denx_get_power_state_XXX.py
+ and adapt the commands to your needs.
+
+ If the power of the board is on, call "tb.end_tc(True)"
+ else "tb.end_tc(False)"
+
+ - set in your board config file:
+ self.tc_lab_denx_get_power_state_tc = 'tc_lab_denx_get_power_state_XXX.py'
+
+ Task c) connect to the boards console:
+ default TC for this task is:
+ https://github.com/hsdenx/tbot/blob/master/src/tc/tc_lab_denx_connect_to_board.py
+
+ - now copy this file to for example
+ (replace XXX to a proper value)
+ cp src/tc/tc_lab_denx_connect_to_board.py src/tc/tc_lab_denx_connect_to_board_XXX.py
+ and adapt the commands to your needs.
+
+ As this TC powers on the board for all your boards in your VL,
+ you can differ between the boards through the tbot class
+ variable "tb.boardlabname" (which is in the default case the
+ same as "tb.boardname"), but you may need to name the power target
+ with an other name than boardname, so you can configure this case.
+
+ If connect fails end this TC with "tb.end_tc(False)"
+ else call "tb.end_tc(True)"
+
+ If you want to use kermit for connecting to the boards console, you
+ can use:
+
+ https://github.com/hsdenx/tbot/blob/master/src/tc/tc_workfd_connect_with_kermit.py
+
+ Example for such a board in the VL from denx:
+ self.tc_lab_denx_connect_to_board_tc = 'tc_workfd_connect_with_kermit.py'
+ https://github.com/hsdenx/tbot/blob/master/tbot_dxr2.cfg#L24
+
+ Hopefully this works for you too.
+
+ - set in your board config file:
+ self.tc_lab_denx_connect_to_board_tc = 'tc_lab_denx_connect_to_board_XXX.py'
+
+ remarks while writting this:
+ - Currently there is only the denx VL. Original idea was to include
+ other VL through a seperate class/file in
+ https://github.com/hsdenx/tbot/tree/master/src/lab_api
+ but it turned out, that if we say "ssh" is the standard way to connect
+ to a VL, we can integrate the VL specific tasks through testcases, see
+ above, so we should do:
+ - rename the "denx" API to a more general name.
+ This is a point on my ToDo list ... done, renamed to 'ssh_std'
+
+ - the VL specific configuration may moved from the board config files
+ and should be collected in VL specific config files, which boards
+ config file simple include.
+
+- prepare password.py file:
+ This file contains all passwords tbot needs (for example for
+ linux login on the boards)
+ tbot searches this file in the tbot root directory.
+ It is a simple python file, for example:
+
+ # passwords for the lab
+ if (board == 'lab'):
+ if (user == 'hs'):
+ password = 'passwordforuserhs'
+ if (user == 'root'):
+ password = 'passwordforrootuser'
+ # passwords for the boards
+ elif (board == 'mcx'):
+ if (user == 'root'):
+ password = 'passwordformcxrootfs'
+ else:
+ if (user == 'root'):
+ password = ''
+
+ In the above example passwords for logging into the Lab PC tbot finds
+ through:
+ if (board == 'lab'):
+ user = 'name':
+ password = 'gnlmpf' # password 'gnlmpf' for login of user 'name'
+
+- prepare board config file
+ Each board which is found in the VL needs a tbot configuration file
+ pass the config file name with the option '-c' to tbot, tbot searches
+ in the root dir for them.
+
+ board Example (dxr2 board):
+ https://github.com/hsdenx/tbot/blob/master/tbot_dxr2.cfg
+
+ Necessary variables:
+
+ line 3: boardname, here it is the "etamin" board
+ no default value, must be set.
+ line 4: boardlabname: name used for connecting to the board
+ may differ from tb.boardname, default tb.boardname
+ line 5: boardlabpowername: name used for power on/off
+ may differ from tb.boardname, default tb.boardname
+ line 6: tftpboardname: name used for tftp subdir (from where
+ U-Boot loads images for example).
+ may differ from tb.boardname, default tb.boardname
+ line 7: labprompt: linux prompt tbot sets
+ no defaultvalue, must be set (maybe we should introduce
+ "ttbott" as default ...
+ line 8: debug: If True, adds debug output on the tbot shell
+ line 9: debugstatus: enable status debug output on the shell
+ line 10: ip: Where tbot finds the Lab PC
+ line 11: user: As which user does tbot logs into the Lab PC
+ line 12: accept_all: passed to paramiko, accept all connections
+ line 13: keepalivetimout: passed to paramiko, timeout for sending
+ keepalive message.
+ line 14: channel_timeout: passed to paramiko
+ line 15: loglevel: tbots loglevel for adding entries into the logfile.
+ line 16: lap_api: used lap API (currently only 'ssh_std')
+ Should be declared as standard -> this line would be not needed
+ longer.
+ line 17: wdt_timeout: timeout in seconds for tbots watchdog.
+ Watchdog gets triggered if prompt get read.
+ line 20,21: include 'ssh_std' api
+ should be removed.
+ line 24: tc_lab_denx_connect_to_board_tc: Which TC is used for
+ connecting to the boards console the TC, here:
+ https://github.com/hsdenx/tbot/blob/master/src/tc/tc_workfd_connect_with_kermit.py
+ line 27: uboot_prompt: boards U-Boot prompt
+ line 28: linux_prompt: boards linux prompt
+
+ Now comes a list of variables TC needs, this vary from which TC
+ you start on the board.
+
+Thats it ... you now can call tbot and hopefully, it works ;-)
+Find an example log [3] for calling simple U-Boot TC for setting
+an U-Boot Environmentvariable.
+
+If you have problems in setting tbot up, please contact me
+(and may give me ssh access to your Lab PC ;-)
+
+If you have running your first TC [3], you may want to write now your own
+TC (and hopefully share them), so continue with:
