.Example ezsteps with logpro rules
-----------------
[ezsteps]
lookittmp   ls /tmp

[logpro]
lookittmp ;; Note: config file format supports multi-line entries where leading whitespace is removed from each line
  ;;     a blank line indicates the end of the block of text 
  (expect:required in "LogFileBody" > 0 "A file name that should never exist!" #/This is a awfully stupid file name that should never be found in the temp dir/)

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

To transfer the environment to the next step you can do the following:

.Propagate environment to next step
----------------------------
$MT_MEGATEST -env2file .ezsteps/${stepname}	  
----------------------------

Automatic environment propagation with Ezsteps
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Simply give your step name an extension of .sh or .csh. The environment variables will be propagated.

NOTE: aliases and variables with strange whitespace or characters will not propagate correctly. Put in a ticket on the http://www.kiatoa.com/fossils/megatest site if you need support for a specific strange character combination.













.Example of auto propagation
---------------------------
[ezsteps]
step1.sh export SOMEVAR=$(ps -def | wc -l);ls /tmp
# The next step will get the value of $SOMEVAR from step1.sh
step2.sh echo $SOMEVAR
---------------------------

testname1/itempath A comment about why it was waived
testname2          A comment for a non-itemized test 
---------------------------

Ezsteps
~~~~~~~

Ezsteps is the recommended way to implement tests and automation in Megatest.

NOTE: Each ezstep must be a single line. Use the [scripts] mechanism to create multiline scripts (see example below).

.Example ezsteps with logpro rules
-----------------
[ezsteps]
lookittmp   ls /tmp

[logpro]
lookittmp ;; Note: config file format supports multi-line entries where leading whitespace is removed from each line
  ;;     a blank line indicates the end of the block of text 
  (expect:required in "LogFileBody" > 0 "A file name that should never exist!" #/This is a awfully stupid file name that should never be found in the temp dir/)

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








Automatic environment propagation with Ezsteps
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Turn on ezpropvars or simply give your step name an extension of .sh or .csh. The environment variables will be propagated.

NOTE: aliases and variables with strange whitespace or characters will not propagate correctly. Put in a ticket on the http://www.kiatoa.com/fossils/megatest site if you need support for a specific strange character combination.

.Turn on auto propagate for bash
---------------------------
[setup]
ezpropvars sh /bin/bash
---------------------------

.Turn on auto propagate for csh
---------------------------
[setup]
ezpropvars csh /bin/csh
---------------------------

.Example of auto propagation using extensions
---------------------------
[ezsteps]
step1.sh export SOMEVAR=$(ps -def | wc -l);ls /tmp
# The next step will get the value of $SOMEVAR from step1.sh
step2.sh echo $SOMEVAR
---------------------------

.Example of multi-line script
---------------------------
[scripts]
tarresults tar cfvz $DEST/srcdir1.tar.gz srcdir1
  tar cfvz $DEST/srcdir2.tar.gz srcdir2

[setup]
ezpropvars sh

[ezsteps]
step1 DEST=/tmp/targz;source tarresults
---------------------------

The above example will result in files; tarresults and ez_step1 being
created in the test dir.
