<a class="toc" name="toc-Subsection-1.1">1.1</a> Megatest design philosophy
</h2>
<div class="Standard">
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="Subsection">
<a class="toc" name="toc-Subsection-1.2">1.2</a> Megatest architecture
</h2>
<div class="Standard">
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.

Chicken scheme and a number of “eggs” are required for building megatest. See the file utils/installall.sh for an automated way to install the dependencies on Linux.

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. Writing Makefiles is beyond the scope of this document but here is a minimal example that will run “runsim cpu1” and “runsim cpu2” in parallel.

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”.

<a class="toc" name="toc-Subsection-1.1">1.1</a> Megatest design philosophy
</h2>
<div class="Standard">
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="Subsection">
<a class="toc" name="toc-Subsection-1.2">1.2</a> Megatest architecture
</h2>
<div class="Standard">
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.

Chicken scheme and a number of “eggs” are required for building megatest. See the file utils/installall.sh for an automated way to install the dependencies on Linux.

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”.

</h2>
<div class="Standard">
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="Subsection">
<a class="toc" name="toc-Subsection-1.2">1.2</a> Megatest architecture
</h2>
<div class="Standard">
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.

<h2 class="Subsection">
<a class="toc" name="toc-Subsection-2.1">2.1</a> Dependencies
</h2>
<div class="Standard">
Chicken scheme and a number of “eggs” are required for building megatest. See the file utils/installall.sh for an automated way to install the dependencies on Linux.
</div>
<h2 class="Subsection">
<a class="toc" name="toc-Subsection-2.2">2.2</a> Build and Install

Run “make test” to create the megatest executable. You may wish to copy the executable to a centrally accessible location.

</h2>
<div class="Standard">
Create the file megatest.config using the megatest.config template from the tests directory. At a minimum you need the following:

<div class="Standard">
<div class="listing">
<pre class="listing"># Fields are the keys under which your test runs are organized

field1 TEXT

# the job is managed on the target host by megatest,
# comment out launcher to run local only. An example launcher
# "nbfake" can be found in the utils directory. 
launcher nbfake
​
# The disks section specifies where the tests will be run. As you
# run out of space in a partition you can add additional disks
# entries.
# Format is:
# name /path/to/area

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”.
