<h2 id="_why_megatest">Why Megatest?</h2>
<div class="sectionbody">
<div class="paragraph"><p>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 I had written or
maintained several such tools at different companies over the years. I
thought a single open source tool, flexible enough to meet the needs
of any team doing continuous integration and or running a complex
suite of tests for release qualification would solve some problems for
me and for others.</p></div>

<h2 id="_megatest_design_philosophy">Megatest Design Philosophy</h2>
<div class="sectionbody">
<div class="paragraph"><p>Megatest is a distributed system 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.</p></div>
<div class="ulist"><ul>
<li>
<p>
Self-checking - make it as easy as possible to write self-checking
tests (as opposed to using deltas, i.e. tests that compare with a
previous measurement to deterine PASS/FAIL).
</p>
</li>
<li>
<p>
Traceable - environment variables, host OS and other possibly
influential variables are captured and kept recorded.
</p>
</li>
<li>
<p>
Immutable - once a test is run it cannot be easily overwritten or
modified accidentally.
</p>
</li>
<li>
<p>
Repeatable - test results can be recreated in the future using all
the original variables.
</p>
</li>
<li>
<p>
Relocatable - the testsuite or automation area can be checked out
and the tests run anywhere in the disk hierarchy.
</p>
</li>
<li>
<p>
Encapsulated - the tests run in self-contained directories and all
inputs and outputs to the process can be found in the run areas.
</p>
</li>
<li>
<p>
Deployable - a testsuite is self-contained and can be bundled with
a software project and easily used by others with little to no
setup burden.

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. Megatest has been used with the Intel Netbatch and
lsf (also known as openlava) batch systems and it should be
straightforward to use it with other similar systems.</p></div>

<img src="megatest-stand-alone-area.png" alt="Static">
</div>
</div>
<div class="paragraph"><p>Megatest is designed as a distributed or decoupled system. This means
you can run the areas stand-alone with no additional
infrastructure. I.e. there are no databases, web servers or other
centralized resources needed. However as your needs grow you can
integrate multiple areas into a bigger system.</p></div>

<li>
<p>
Multi-area dashboard and xterm. A gui (the dashboard) is usually the
best option for controlling and launching runs but all operations
can also be done from the commandline. Note: The not yet released
multi-area dashboard replaces the old dashboard for browsing and
controlling runs but for managing a single area the old dashboard
works very well.
</p>
</li>
<li>
<p>
Area/testsuite. This is your testsuite or automation definition and
consists of the information in megatest.config, runconfigs.config
and your testconfigs along with any custom scripting that can’t be
done with the native Megatest features.
</p>
</li>
<li>
<p>
If your testsuite or build automation is too large to run on a
single instance you can distribute your jobs into a compute server
pool. The only current requirements are password-less ssh access and
a network filesystem.

Overflow database methodology - combine the best of the v1.63
multi-db approach and the current db-in-tmp approach (currently
slowness can be seen when number of tests in a db goes over 50-100k,
with the overflow db it will be able to handle 1000’s of runs with
50-100k tests per run). High priority - goal is to complete this by
20Q3.

<h3 id="_examining_the_environment">Examining The Environment</h3>
<div class="sect3">
<h4 id="_test_control_panel_xterm">Test Control Panel - xterm</h4>
<div class="paragraph"><p>From the dashboard click on a test PASS/FAIL button. This brings up a test control panel. Aproximately near the center left of the
window there is a button "Start Xterm". Push this to get an xterm with the full context and environment loaded for that test. You can run
scripts or ezsteps by copying from the testconfig (hint, load up the testconfig in a separate gvim or emacs window). This is the easiest way
to debug your tests.</p></div>
</div>
<div class="sect3">
<h4 id="_during_config_file_processing">During Config File Processing</h4>
<div class="paragraph"><p>It is often helpful to know the content of variables in various
contexts as Megatest does the actions needed to run your tests. A handy technique is to force the startup of an xterm in the context being examined.</p></div>
<div class="paragraph"><p>For example, if an item list is not being generated as expected you
can inject the startup of an xterm as if it were an item:</p></div>
<div class="listingblock">
<div class="title">Original items table</div>
<div class="content monospaced">
<pre>[items]
CELLNAME [system getcellname.sh]</pre>

<div class="title">Items table modified for debug</div>
<div class="content monospaced">
<pre>[items]
DEBUG [system xterm]
CELLNAME [system getcellnames.sh]</pre>
</div></div>
<div class="paragraph"><p>When this test is run an xterm will pop up. In that xterm the
environment is exactly that in which the script "getcellnames.sh"
would run. You can now debug the script to find out why it isn’t
working as expected.</p></div>
</div>
<div class="sect3">
<h4 id="_organising_your_tests_and_tasks">Organising Your Tests and Tasks</h4>
<div class="paragraph"><p>The default location "tests" for storing tests can be extended by

<pre>[misc]
parent #{shell dirname $(readlink -f .)}
[tests-paths]

</div></div>
<div class="paragraph"><p>The above example shows how you can use addition sections in your
config file to do complex processing. By putting results of relatively
slow operations into variables the processing of your configs can be
kept fast.</p></div>
