<a class="toc" name="toc-Section-1.1">1.1</a> Megatest design philosophy
</h2>
<div class="Unindented">
Megatest is intended to provide the minimum needed resources to make writing a suite of tests 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. A call to megatest can then be made to record the result. 
</div>
<h2 class="Section">
<a class="toc" name="toc-Section-1.2">1.2</a> Megatest architecture
</h2>
<div class="Unindented">
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.

A good way to run steps in parallel within a single test, especially when there are following steps, is to use the Unix Make utility.

Sometimes a test depends on the output from a previous test or it may not make sense to run a test is another test does not complete with status “PASS”. In either of these scenarios you can use the “waiton” keyword in your testconfig file to indicate that this test must wait on one or more tests to complete before being launched. In this example there is no point in running the “system” test if the “cpu” and “mem” tests either do not complete or complete but with status “FAIL”.
