The Modern Development Workflow

Automate, Automate, Automate!


Before We Get Started…

• I Am…o Daniel Cousineau

• Lead Developer at Net Perspective, LLC• [email protected]

• We Are…o Full service web agency (development) firm based out of

College Station, TX

• About This Topic…o The utilities presented are biased towards PHP and OSS

• All are interchangeable with other languages and utilities

o We are always improving and getting bettero Constructive feedback always welcome

Source Control

• More than 0 people on a project?o Extremely beneficial when with 2+ member teams

• SVN most popularo Integration with EVERYTHING

o Showing its age• No native branching/tagging

• GIT: the up-and-coming superstaro Not as well integrated

o Still new


Unit Testing

• Old and Busted: GDB, New Hotness: TDDo Test Driven Development

o Write tests first, code until all tests pass

• PHPUnit very popularo Based on the NUnit standard (JUnit sound familiar?)

• Our Goal? 100% Code Coverageo Means every line of source code should have been

executed at least once when all tests completed

• Alternativeso SimpleTest, PHPT


PHPUnit Exampleclass StringFunctionTest extends PHPUnit_Framework_TestCase

{

protected $_fixture;

//Run before each test

public function setup()

{

$this->_fixture = fopen("./sample.txt","w");

}

//Example test

public function testStrToLower()

{

//Object is constructed/destructed after each test

//Data saved to a fixture here is not preserved for the next test

$actual = strtolower("SaMpLe");

$expected = "sample";

$this->assertEquals($expected, $actual, 'comment here'); //

}

//Run after each test

public function tearDown()

{

fclose($this->_fixture);

}

}


Build Management

• Generating AutoDoc, running UnitTests, and packaging is BORINGo “Laziness is the mark of a great developer” – Me

• Automate with Phingo Native PHP build system based on the popular Ant build

system for Javao $ phing TARGET_NAME

• Looks for build.xml which contains commands for the target

o Tasks for running PHPDoc, PHPUnit, and…


Phing Example<?xml version="1.0" encoding="UTF-8"?>

<project name="Latitude" default="dist" basedir=".">

<target name="test">

<phpunit2 haltonfailure=“true" haltonerror=“true" printsummary="true">

<batchtest classpath="${project.basedir}/lib">

<fileset dir="${project.basedir}/tests">

<include name="RouteTest.php" />

<include name="DispatcherTest.php" />

</fileset>

</batchtest>

</phpunit2>

</target>

<target name="doc" depends="test">

<phpdoctitle="Latitude API Documentation“ destdir="${project.basedir}/docs/“ >

<fileset dir="${project.basedir}/lib" >

<include name="**/*.php" />

</fileset>

</phpdoc>

</target>

<target name="dist" depends="test">

<tar destfile="${project.basedir}/builds/latitude.tar.gz" compression="gzip">

<fileset dir="${project.basedir}">

<exclude name="**/.svn" />

</fileset>

</tar>

</target>

</project>


Database Versioning

• DBDeployo Every change to the database structure is in its own .sql file

• Each file contains the SQL to perform changes and SQL to roll back those changes

o Revision information is stored in a table

o Written in Java, Phing has a native port built in

o Only version structure changes and default values• Don’t version test and sample data!


DBDeploy Example

--//

CREATE TABLE `sample` (

`id` INT UNSIGNED NOT NULL AUTO_INCREMENT ,

PRIMARY KEY (`id`) )

ENGINE = InnoDB;

--//@UNDO

DROP TABLE `sample`;

--//

db/deltas/1-REVISION_COMMENT.sql


Continuous Integration

• Wraps everything up…o Ties in Versioning, Build Management, Unit Testing, [Auto

generated Documentation, ] and Database Versioning

o Xinc (http://xinc.eu) (a pure PHP solution)• CruiseControl would be the “original”

• What happens?o CI monitors SVN working copy

o On update, run specified build script (Phing)• Phing generates UnitTest reports, API documentation, and archive files

• Deployment code (upload to live server?)

• UnitTest fails? Build fails

o Store “artifacts” (generated reports, etc.) for each build

Xinc Interface

Notice the Deliverable and Documentation artifacts
