gathered metrics from the Moodle Community and Survey 2 gathered
metrics from Moodle Partners. Limiting factors of these surveys are
that both samples are relatively small. The results of the surveys
are as follows:</P>

<P>As Debian and Ubuntu are similar and Red Hat and
Centos are similar that,based upon our sample data, our three main
operating used by the Moodle community Debian/Ubuntu, Red Hat/Centos
and MS Server 2008 with a weighting of almost 75% towards the two
Linux operating systems.</P>
<P>Of the five supported databases, the majority of
community users prefer MySQL with PostgreSQL and MSSQL a fairly equal
but distant second and third.</P>
<P>The Majority of community users also use Apache with
IIS a very distant second.</P>

<P>This suggests that the majority of partners use
Debian/Ubuntu or Centos/Rad Hat Linux, Apache and either a MySQL or
PostgreSQL database.
</P>
<H2 CLASS="western">VM Requirements</H2>
<P>In true agile fashion and to promote flexibility,
VM's for test environments will be modular i.e. they will be separate
database servers and web servers. This will allow the mixing and
matching of databases and their host OS to the web servers and their
host OS as requirements change. At any time, any Web Server can
connect to any Database Server. It should also reduce potential
numbers of running VMs required for a particular platform.</P>
<P>A master hub VM is required for Jenkins and the hub for the Selenium
grid.</P>
<H1 CLASS="western" STYLE="page-break-before: always">Implementation</H1>
<P>Agile testing guru and automation expert Brian Marick
coined the term “Hump of Pain” to describe the initial phase of
implementing test automation. The impact of this hump can be
minimised by good planning, good coaching and a strong managerial
support for the new processes. As time progresses, particularly as
infrastructure becomes implemented, the test cases in the automated
suite are completed and the introduced practices become second
nature; the hump disappears.</P>
<H2 CLASS="western">Agile Implementation of Testing
Practices</H2>
<P>Modifications to the process should be made in an incremental
manner based up scrum methodology. A series of 2 weekly sprints will
be used to time-box test planning and implementation tasks.</P>
<H2 CLASS="western">Phase 1: Infrastructure and the
Integration Process</H2>
<P>The infrastructure to maintain automated testing
effort must be implemented. This process will start with the
installation of cloud based hardware at Moodle HQ and the setup of
VM's to support the required test environments.</P>
<P>The integration process affects quality for the whole
organisation as all code must go through the integration process to
become 'live'. The processes described above will will be initially
implemented at integration. Any changes to the existing processes
will take place side-by-side with existing processes to manage risk.
i.e. existing processes impacted by changes will be maintained in
their current state until implementation of changes becomes stable.</P>
<P>The setup of test environments will initially start
with a restricted number of high risk test environments so that the
automation process, particularly test cases, can be developed
incrementally.</P>

Introduction

Purpose

The purpose of this document is to define a high level QA strategy at Moodle and communicate that process to the relevant stakeholders.

This document is test centric, only explaining the development process from a testing point of view. The scope of this document does not cover the details of the entire development process at Moodle but how testing is applied to it. This document also discusses potential benefits to the organization of the processes discussed. Currently the processes that are documented here are under development. Progress can be viewed via the Testing Roadmap

Scope

This document encompasses all testing activities at Moodle and how they will be performed. This includes:
