This is the tapper-autoreport bash utility -- a bash include file that you include ("source") at the end of your own bash script.

It then magically turns your bash script into a Tapper test suite.

It collects meta information from system, reports test results via network and uploads files.

It also allows your bash script to be used with the prove command, a tool to run test scripts that produce TAP output (Test Anything Protocol).


most simple usage

  • script:
#! /bin/bash
# your own stuff here ...
. /tapper-autoreport
  • explanation:

    • TAP
    • filename gets name
    • run itself is already a success
    • meta information
    • report grouping heuristics
    • self-report to Tapper
    • upload files
    • print out Tapper report URL

using environment variables and params

  • script:
#! /bin/bash
append_tap "ok - affe loewe tiger"
append_tap "ok - some other description"
append_tap "not ok - yet another test description"
append_tapdata "timecpb: 12.345"
append_tapdata "timenocpb: 23.456"
OSNAME="Gentoo 10.1"
uname -a | grep -q Linux  # example for exit code
. /tapper-autoreport nok /tmp/results.log $?
  • explanation:

    • define additional TAP lines
    • define additional YAML data lines
    • overwrite suite name
    • overwrite suite version
    • overwrite OS name
    • overwrite changeset, usually kernel
    • overwrite hostname
    • specify relevant URL in used ticket system (like Bugzilla, RT, ...)
    • specify relevant URL in used wiki
    • specify relevant task planning id (like MS Project, TaskJuggler, ...)
    • use different report server (e.g. "tapper-devel" for experiments)
    • set NOSEND=1 to suppress sending to reports server completely
    • param "nok" say "something was not ok"
    • param of filename /tmp/my_ow_results.txt means upload the file
    • param of integer ($? is last exit code, 0 means ok, else not ok)

use with prove

  • cmd line and output:
$ prove ./
./ .. ok
All tests successful.
Files=1, Tests=5, 20 wallclock secs
Result: PASS
  • explanation:

    • "prove" is an existing standard tool
    • it prints success statistics
    • no report sending happens
    • is meant for manual developing/testing

use without prove

  • cmd line and output:
$ ./
# - upload ./ ...
# - upload /boot/config-2.6.32-22-generic ...
# - upload /proc/cpuinfo ...
# - upload /proc/devices ...
# - upload /proc/version ...
  • explanation:

    • execute script
    • report output to Tapper server
    • upload files
    • prints out Tapper report URL
    • is meant for final reporting


  • use environment variables to provide more content
  • define hooks (functions) to be called
  • provide params that "Do What I Mean"
  • call script with "prove" utility to test directly without upload

Environment Variables

  • TAP[*] - Array of TAP lines
  • TAPDATA[*] - Array of YAML lines that contain data in TAP
  • HEADERS[*] - Array of Tapper headers
  • OUTPUT[*] - Array of additional output lines
  • SUITENAME - alternative suite name instead of $0
  • SUITEVERSION - alternative suite version
  • KEYWORDS - space separated keywords to influence suite name
  • OSNAME - alternative OS description
  • CHANGESET - alternative changeset
  • HOSTNAME - alternative hostname
  • TAPPER_REPORT_SERVER - alternative report server
  • TICKETURL - relevant URL in used ticket system (Bugzilla)
  • WIKIURL - relevant URL in used wiki
  • PLANNINGID - relevant task planning id (MS Project, TaskJuggler)
  • NOSEND - if "1" no sending to Tapper happens
  • NOUPLOAD - if "1" no uploading of default files happens

Utility functions

Import utility functions at the beginning of the script via

. ./tapper-autoreport --import-utils

Then you have the following functions available

  • require_cpufeature "cpb"

Checks that the string "cpb" in /proc/cpuinfo and exits in a TAP conform way otherwise.

  • require_program "bc"

Checks that the program "bc" is available and exits in a TAP conform way otherwise.

  • require_root

Checks that the user executing the script is root (UID 0).

  • ok ARG1 "some description"

Evaluates the first argument with Shell boolean semantics (0 is true) and appends a corresponding TAP line.

  • negate_ok ARG1 "some description"

Evaluates the first argument with Shell inverse boolean semantics (0 is false) and appends a corresponding TAP line.

  • append_tap "ok - some description"

Appends a complete TAP line where you have taken care for the "ok"/"not ok" at the beginning.

  • append_tapdata "key: value"

Appends a key:value line at the tapdata YAML block. The key must start with letter and consist of only alphanum an underscore.

Command Line Arguments

  • --version - print version number and exit
  • nok - declare something was not ok
  • [integer] - exit code of a program, 0 == ok, else not (Hint: use '$?' to refer to last program)
  • [filename] - upload the file

Function Hooks

  • main_after_hook()

    • optional shell function to be executed at the end of autoreport's main()
    • all stdout will be part of the report
