++ Development environmentSeveral issues to solve when working on a project as a team



7/42


++ Development environmentDevelopers OS

Can be VERY heterogene

IT Departments may impose an OS (Windows in most cases)

BUT you need to work in an environment as close as possible from the targetenvironment

VMs are a suitable solution (Virtual Box, VMWare...)

Several issues to solve when working on a project as a team



8/42








Developers coding environmentEach developer has its preferred IDE

Unicity rimes with productivity => Choose only one IDE (I chose Eclipse)

Easier for developer support or when welcoming a new developer in the team

A good IDE provides all needed tools all-in-one

Developers synchronicitySharing the same sources (SCM like Subversion or Git)

Sharing the same database

Sharing the same media files

Even when working with developers who are far from each other

++ Development environment : a solutionEclipse PDT with useful plugins

Smile eZ Publish plugin (TPL syntax highlight, code completion & content class view)

eZClipse (TPL & INI syntax highlight)

Subversive

Mylyn (Bug tracker integration : Mantis, Trac, Bugzilla, Jira...)

FileSync(see below)

Virtual BoxWith an image close to target environment (lets say Ubuntu Server)

Can be run from a dedicated headless server with VBoxHeadless

FileSync Eclipse pluginSync your workspace with a remote server

Your remote server has to be accessible from your local/host computer

Samba or SSHFS are good solutions

Common dedicated MySQL server

eZ Publish (Database cluster mode enabled) + useful extensions

Subversion

++ Development environment : a solutionForeign developers case

Different geographical centers working together on the same project

Freelances

Everyone needs to share the same database (Data & Cluster files)



12/42




Freelances


IssuesToo much potential traffic with the database over the internet

Slow

Insecure

Freelances


IssuesToo much potential traffic with the database over the internet

Slow

Insecure

SolutionDedicated Virtual Box Headless server, located in the Project Headquarter

Each foreign developer has its dedicated remote VBox

Sources are sent through SSHFS or Samba (with VPN) via FileSync automatically

Each VBox is local to the database serverDeveloper accesses to its own development server through HTTP and/or SSH

Fast and secure :-)

++ Unit tests in eZ PublishUnit tests development are NEVER a waste of time

You spend 15-25% more time developing tests

You spend 10-20% less time debugging in the clients test phase

Unit tests then become non-regression tests

++ Continuous Integration PlatformAutomatically builds your applicationUpdates from your SCM

Runs your unit and functional tests

Tests your code against your coding standards (PHPCodeSniffer)

Detects messy code (PHPMessDetector)

Makes reports and graphs about these builds
