Preface

-
-

This book is organised as three sub-books; getting started, writing tests and reference.

-
-

Why Megatest?

-

The Megatest project was started for two reasons, the first was an -immediate and pressing need for a generalized tool to manage a suite -of regression tests and the second was the fact that the author had -written or maintained several such tools at different companies over -the years and it seemed a good thing to have a single open source -tool, flexible enough to meet the needs of any team doing continuous -integrating and or running a complex suite of tests for release -qualification.

-
-
-

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. In most cases megatest is best used in conjunction -with logpro or a similar tool to parse, analyze and decide on the test -outcome.

-
-
-

Megatest Architecture

-

All data to specify the tests and configure the system is stored in -plain text files. All system state is stored in an sqlite3 -database. Tests are launched using the launching system available for -the distributed compute platform in use. A template script is provided -which can launch jobs on local and remote Linux hosts. Currently -megatest uses the network filesystem to call home to your master -sqlite3 database.

-
-

Road Map

Note 1: This road-map is tentative and subject to change without notice.

Note 2: Starting over. Old plan is commented out.

-
Getting started with Megatest
-
-

How to install Megatest and set it up for running your regressions and continuous integration process.

-
-
-

Installation

-
-
-

Dependencies

-

Chicken scheme and a number of "eggs" are required for building -Megatest. See the script installall.sch in the utils directory of the -distribution for a mostly automated way to install everything needed -for building Megatest on Linux.

How To Do Things

-
-

Tricks

-
-

This section is a compendium of a various useful tricks for debugging, -configuring and generally getting the most out of Megatest.

-
-
-
-

Limiting your running jobs

-
-

The following example will limit a test in the jobgroup "group1" to no more than 10 tests simultaneously.

-

In your testconfig:

-
-
-
[test_meta]
-jobgroup group1
-
-

In your megatest.config:

-
-
-
[jobgroups]
-group1 10
-custdes 4
-
-
-
-
-

Debugging Tricks

-
-
-

Examining The Environment

-
-

During Config File Processing

-
-
-

Organising Your Tests and Tasks

-
-
-
[tests-paths]
-1 #{get misc parent}/simplerun/tests

-
-
-
[setup]
-
-

The runscript method is a brute force way to run scripts where the -user is responsible for setting STATE and STATUS

-
-
-

Wait on Other Tests

-
-
-
# A normal waiton waits for the prior tests to be COMPLETED
-# and PASS, CHECK or WAIVED
-waiton test1 test2
-
-
-
-

Mode

-

The default (i.e. if mode is not specified) is normal. All pre-dependent tests -must be COMPLETED and PASS, CHECK or WAIVED before the test will start

-
-
-
mode   normal
-
-

The toplevel mode requires only that the prior tests are COMPLETED.

-
-
-
mode toplevel
-
-

A item based waiton will start items in a test when the -same-named item is COMPLETED and PASS, CHECK or WAIVED -in the prior test

-
-
-
mode itemmatch
-
-
-
-
# With a toplevel test you may wish to generate your list
-# of tests to run dynamically
-#
-# waiton #{shell get-valid-tests-to-run.sh}
-
-
-
-

Run time limit

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

Skip

-
-
-

Header

-
-
-
[skip]
-
-
-
-

Skip on Still-running Tests

-
-
-
# NB// If the prevrunning line exists with *any* value the test will
-# automatically SKIP if the same-named test is currently RUNNING
-
-prevrunning x
-
-
-
-

Skip if a File Exists

-
-
-
fileexists /path/to/a/file # skip if /path/to/a/file exists
-
-
-
-

Controlled waiver propagation

-

If test is FAIL and previous test in run with same MT_TARGET is WAIVED then apply the following rules from the testconfig: -If a waiver check is specified in the testconfig apply the check and if it passes then set this FAIL to WAIVED

-

Waiver check has two parts, 1) a list of waiver, rulename, filepatterns and 2) the rulename script spec (note that "diff" and "logpro" are predefined)

-
-
-
###### EXAMPLE FROM testconfig #########
-# matching file(s) will be diff'd with previous run and logpro applied
-# if PASS or WARN result from logpro then WAIVER state is set
-#
-[waivers]
-# logpro_file    rulename      input_glob
-waiver_1         logpro        lookittmp.log
-
-[waiver_rules]
-
-# This builtin rule is the default if there is no <waivername>.logpro file
-# diff   diff %file1% %file2%
-
-# This builtin rule is applied if a <waivername>.logpro file exists
-# logpro diff %file1% %file2% | logpro %waivername%.logpro %waivername%.html
-

Ezsteps

-

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

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

Triggers

-

In your testconfig 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.

-

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 --

Preface

+
+

This book is organised as three sub-books; getting started, writing tests and reference.

+
+

Why Megatest?

+

The Megatest project was started for two reasons, the first was an +immediate and pressing need for a generalized tool to manage a suite +of regression tests and the second was the fact that the author had +written or maintained several such tools at different companies over +the years and it seemed a good thing to have a single open source +tool, flexible enough to meet the needs of any team doing continuous +integrating and or running a complex suite of tests for release +qualification.

+
+
+

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. In most cases megatest is best used in conjunction +with logpro or a similar tool to parse, analyze and decide on the test +outcome.

+
+
+

Megatest Architecture

+

All data to specify the tests and configure the system is stored in +plain text files. All system state is stored in an sqlite3 +database. Tests are launched using the launching system available for +the distributed compute platform in use. A template script is provided +which can launch jobs on local and remote Linux hosts. Currently +megatest uses the network filesystem to call home to your master +sqlite3 database.

+
+
+
+

+

How to install Megatest and set it up for running your regressions and continuous integration process.

+
+
+

Installation

+
+
+

Dependencies

+

Chicken scheme and a number of "eggs" are required for building +Megatest. See the script installall.sch in the utils directory of the +distribution for a mostly automated way to install everything needed +for building Megatest on Linux.

How To Do Things

+
+

Tricks

+
+

This section is a compendium of a various useful tricks for debugging, +configuring and generally getting the most out of Megatest.

+
+
+
+

Limiting your running jobs

+
+

The following example will limit a test in the jobgroup "group1" to no more than 10 tests simultaneously.

+

In your testconfig:

+
+
+
[test_meta]
+jobgroup group1
+
+

In your megatest.config:

+
+
+
[jobgroups]
+group1 10
+custdes 4
+
+
+
+
+

Debugging Tricks

+
+
+

Examining The Environment

+
+

During Config File Processing

+
+
+

Organising Your Tests and Tasks

+
+
+
[tests-paths]
+1 #{get misc parent}/simplerun/tests
+
+
+
+
[setup]
+
+

The runscript method is a brute force way to run scripts where the +user is responsible for setting STATE and STATUS

+
+
+
runscript main.csh
+
+

Wait on Other Tests

+
+
+
# A normal waiton waits for the prior tests to be COMPLETED
+# and PASS, CHECK or WAIVED
+waiton test1 test2
+
+
+
+

Mode

+

The default (i.e. if mode is not specified) is normal. All pre-dependent tests +must be COMPLETED and PASS, CHECK or WAIVED before the test will start

+
+
+
mode   normal
+
+

The toplevel mode requires only that the prior tests are COMPLETED.

+
+
+
mode toplevel
+
+

A item based waiton will start items in a test when the +same-named item is COMPLETED and PASS, CHECK or WAIVED +in the prior test

+
+
+
mode itemmatch
+
+
+
+
# With a toplevel test you may wish to generate your list
+# of tests to run dynamically
+#
+# waiton #{shell get-valid-tests-to-run.sh}
+
+
+
+

Run time limit

+
+
+
runtimelim 1h 2m 3s  # this will automatically kill the test if it runs for more than 1h 2m and 3s
+
+
+
+

Skip

+
+
+

Header

+
+
+
[skip]
+
+
+
+

Skip on Still-running Tests

+
+
+
# NB// If the prevrunning line exists with *any* value the test will
+# automatically SKIP if the same-named test is currently RUNNING
+
+prevrunning x
+
+
+
+

Skip if a File Exists

+
+
+
fileexists /path/to/a/file # skip if /path/to/a/file exists
+
+
+
+

Controlled waiver propagation

+

If test is FAIL and previous test in run with same MT_TARGET is WAIVED then apply the following rules from the testconfig: +If a waiver check is specified in the testconfig apply the check and if it passes then set this FAIL to WAIVED

+

Waiver check has two parts, 1) a list of waiver, rulename, filepatterns and 2) the rulename script spec (note that "diff" and "logpro" are predefined)

+
+
+
###### EXAMPLE FROM testconfig #########
+# matching file(s) will be diff'd with previous run and logpro applied
+# if PASS or WARN result from logpro then WAIVER state is set
+#
+[waivers]
+# logpro_file    rulename      input_glob
+waiver_1         logpro        lookittmp.log
+
+[waiver_rules]
+
+# This builtin rule is the default if there is no <waivername>.logpro file
+# diff   diff %file1% %file2%
+
+# This builtin rule is applied if a <waivername>.logpro file exists
+# logpro diff %file1% %file2% | logpro %waivername%.logpro %waivername%.html
+
+
+
+
+

Ezsteps

+

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

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

Triggers

+

In your testconfig 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.

+

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 --
+
+
+
+
+
+

Programming API

+
+

These routines can be called from the megatest repl.
