Development Process Workflow


Source Development Tools Progress Developer Studio for OpenEdge Web tools Other Plug-ins e.g. Source code generators etc…


Version Control Revision control, also known as version control or source control is the

management of changes to documents, programs, and other information stored in file system

Best Practices:• Set up change notifications• Version control is not a backup system• Use branches• Write good commit messages

Continuous Integration

Continuous Integration is a software development practice where members of a team integrate their work frequently. Each integration is verified by an automated build to detect integration errors as quickly as possible.

Best Practices:• Maintain single source repository• Automate build process• Commit changes to mainline everyday• Build mainline on integration machine• Keep the build fast• Test in a clone of production environment• Automate deployment

Testing The process of validating and verifying that a software program / application /

product:– meets the requirements that guided its design and development;– works as expected; and– can be implemented with the same characteristics.

Types of testing– Unit Testing - individual classes and methods– GUI Testing - interactive elements– Smoke Testing - software will not crash outright– Integration Testing - modules tested as a group– System Testing - compliance with requirements– Regression Testing - new errors resulting from ongoing changes– Load Testing - measuring response under load– Usability Testing - usability of the application– Security Testing - prevents unauthorized use

OpenEdge Focused Development Tools

Progress Developer Studio for OpenEdge– Eclipse based IDE or modeling and writing ABL applications.

RoundTable– RoundTable is a software configuration management and source code control solution focused

on OpenEdge applications.

Build/Compile– PCT (Progress Compilation Tools) is a set of ANT tasks, designed to build OpenEdge

applications.

Unit testing – It is a method by which individual units of source code are tested to determine if they are fit for

use. There are two xUnit based frameworks, oeunit and prounit available for OpenEdge.

Static program analysis – ProLint is a language parser and set of customizable source code analysis rules for detecting

problems and standards violations in ABL code.


Development Tools Discussion

What development tools (for different technologies) are you using in your environment?

What other plug-ins are you using in your environment? Does it meet your needs? Is it integrated into your build process?


Version Control Discussion

What version control product are you using in your environment? Does it meet all your needs? Is it integrated into your development tools? Is it integrated into your build process?


Continuous Integration Discussion Does your development process include continuous integration? Are you using a continuous integration product? Are your other development practices built on the benefits/hurdles of

your build process?


Software Testing Discussion

Topics to discuss Unit Testing GUI Testing Load Testing

Questions What testing tools are you using in your environment? Does it meet all your needs? Is it integrated into your development tools? Is it integrated into your build process?



Agenda

Welcome Development processes and tools Agile Development process and tools Application packaging and deployment Wrap up and next steps


Agile Development/Manifesto

Style of software development that emphasizes customer satisfaction through continuous delivery of functional software.

Based on a variety of iterative development disciplines including extreme programming (XP)

Agile methods put developers to work in small teams to tight budgets and short timescales

Agile Principles:

• Individuals and interactions over processes and tools

• Working software over comprehensive documentation

• Customer collaboration over contract negotiation

• Responding to change over following a plan


Agile Best Practices

Common Coding guidelines Code Refactoring Code Regression Testing Continuous Integration Test Driven Development Active Stakeholder participation Pair Programming Take a breadth-first approach Smaller is better


Discussion

What agile methodologies have you adopted?

What benefits have you seen?

Do you follow one of the standard agile systems such as scrum, XP, AUP, DSDM, FDD or another one?

Are you using an ALM tool that assists with your agile methodology?

Have you provided any formal agile development training to your developers and product owners?



Agenda



Application Packaging

Application packaging is the process of identifying application components and determining how the components should be installed and configured on client workstations.

Best Practices:• Avoid hard coding of paths• Provide uninstall capability• Provide rollback mechanism• Provide silent installers

“Enterprises that do not dedicate resources to packaging applications will fail at software distribution…”

(0.8 probability)— Gartner Group


Software Deployment

The general process that has to be customized according to specific requirements or characteristics to make a software system available for use.

• Synaptic Package Manager

• Advanced Packaging Tool

• Portage

• Cygwin

• Web Client Application Assembler

• Windows MSI

• InstallShield


Discussion

How do you do packaging?

How do you do deployment?

What packaging/deployment tool are you using?

How “hands-on” are each of the steps?
