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.

Getting Started

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.

[An example footnote.]

And now for something completely different: monkeys, lions and -tigers (Bengal and Siberian) using the alternative syntax index -entries. - - - -Note that multi-entry terms generate separate index entries.

Here are a couple of image examples: an - images/smallnew.png - -example inline image followed by an example block image:

Figure 1. Tiger block image

Followed by an example table:

Table 1. An example table
Option	Description
-a USER GROUP	Add USER to GROUP.
-R GROUP	Disables access to GROUP.

The testconfig File

Setup section

Header

[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

Requirements section

Header

[requirements]

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}
