Megatest Design Philosophy
--------------------------

Megatest is intended to provide the minimum needed resources to make
writing a suite of tests and tasks for implementing continuous build
for software, design engineering or process control (via owlfs for
example) without being specialized for any specific problem
space. Megatest in of itself does not know what constitutes a PASS or
FAIL of a test or task. In most cases megatest is best used in
conjunction with logpro or a similar tool to parse, analyze and decide

on the test outcome. 

 * Self-checking -Repeatable strive for directed or self-checking test

 * Traceable - environment variables, host OS and other possibly influential
   variables are captured and kept recorded.

Disk Space Checks
^^^^^^^^^^^^^^^^^

Some parameters you can put in the [setup] section of megatest.config:

-------------------

Attempt to rerun tests in "STUCK/DEAD", "n/a", "ZERO_ITEMS" states.

.In megatest.config
------------------
[setup]
reruns 5
------------------

Replace the default blacklisted environment variables with user supplied
list.

Default list: USER HOME DISPLAY LS_COLORS XKEYSYMDB EDITOR MAKEFLAGS MAKEF MAKEOVERRIDES

.Add a "bad" variable "PROMPT" to the variables that will be commented out
in the megatest.sh and megatest.csh files:
-----------------
[setup]
blacklistvars USER HOME DISPLAY LS_COLORS XKEYSYMDB EDITOR MAKEFLAGS PROMPT
-----------------

Run time limit
++++++++++++++

-----------------
[setup]
# this will automatically kill the test if it runs for more than 1h 2m and 3s

$MT_MEGATEST -env2file .ezsteps/${stepname}	  
----------------------------

Triggers
~~~~~~~~

In your testconfig triggers can be specified 
In your testconfig or megatest.config triggers can be specified 

-----------------
[triggers]

# Call script running.sh when test goes to state=RUNNING, status=PASS
RUNNING/PASS running.sh

# Call script running.sh any time state goes to RUNNING
RUNNING/ running.sh

# Call script onpass.sh any time status goes to PASS
PASS/ onpass.sh
-----------------

Scripts called will have; test-id test-rundir trigger, added to the commandline.
Scripts called will have; test-id test-rundir trigger test-name item-path state status event-time, added to the commandline.

HINT

To start an xterm (useful for debugging), use a command line like the following:

-----------------
[triggers]
COMPLETED/ xterm -e bash -s -- 
-----------------

NOTE: There is a trailing space after the --

There are a number of environment variables available to the trigger script
but since triggers can be called in various contexts not all variables are
available at all times. The trigger script should check for the variable and
fail gracefully if it doesn't exist.

Override the Toplevel HTML File

iterated tests. The generation can be overridden. NOTE: the output of
