Agenda
• An agilist’s perspective on how to...
• Be More Productive as a PHP Developer
• Be More Productive as a General Developer
• Be More Productive as an Individual

This is NOT a technology deep-dive

Dependency &
Conﬁguration
Management

View Slide

Suppose We Need...
• PHPUnit 2.4.1
• phpDocumentor 2.0.2
• PHPCodeSniffer 2.0.4
• Zend Framework 1.10
• Doctrine 2.1
• ...

View Slide

PEAR!

View Slide

PEAR’s Pitfalls
• System-wide dependency
• Multiple projects; different version dependencies
• Ensuring same versions across developer
workstations / servers

View Slide

Check into Repo!

View Slide

Your repository is to
manage YOUR code

View Slide

Repository Externals!

PHPUnit

View Slide

What is TDD Good For?
• Developers stating known assumptions up-front
• Minimizing production code
• Testing units of code
• Automated suite of regression tests

View Slide

TDD’s Limitations

Integration

View Slide

Integration
You Don’t See the Forest thru the Trees

View Slide

TDD’s Limitations
• QA often don’t trust unit tests
• Business + QA don’t understand unit tests
• Lack of cohesive language to describe acceptance
criteria

View Slide

TDD is the Past
BDD is the Future

View Slide


View Slide

• Tests written in Gerkhin

View Slide

• Given a precondition

View Slide

• When some action occurs

View Slide

• When some action occurs
• Then an outcome is achieved

View Slide

Feature: ls
In order to see the directory structure
As a UNIX user
I need to be able to list the current director
contents
Scenario: List 2 files in a directory
Given I am in directory “test”
And I have a file named “foo”
And I have a file named “bar”
When I run “ls”
Then I should get:
“””
bar
foo
“””

View Slide

Feature: registration
In order to be able to use the system
As a privileged user
I need to be able to register for an account
Scenario: Unmatched username and password
Given I have a password “password”
And I have a confirm password “password2”
When I attempt to register
Then I should get a validation error

View Slide

// You can implement step definitions for undefined steps with
these snippets:
/**
* @Given /Î have a password "([^"]*)"$/
*/
public function iHaveAPassword($arg1)
{
throw new PendingException();
}
/**
* @Given /Î have a confirm password "([^"]*)"$/
*/
public function iHaveAConfirmPassword($arg1)
{
}
/**
* @When /Î attempt to register$/
*/
public function iAttemptToRegister()

/**
* @Then /Î should get a validation error$/

public function iShouldGetAValidationError()

Other BDD Practices

View Slide

Other BDD Practices
• Test behaviors - not units
•Stop mocking/stubbing/faking!
•You are supposed to be writing end-to-end tests
•Plan, build, and automate your testing
environments
•Work with the business/QA to develop acceptance
criteria

View Slide


View Slide

Do you...
• create automated documentation?
• run unit tests with any regular occurrence?
• rebuild/clean/update your database more than once
a week?
• repeat a lot of repetitive command-line tasks?

View Slide

phing
• PHing Is Not GNU make
• Like Apache Ant
• Build Automation Tool

View Slide

phing Capabilities
• Running PHPUnit or SimpleTest test suites
• File Transformations
• Filesystem Operations
• SQL Execution
• CVS/SVN/GIT Operations
• Documentation Generation

Use phing if you...
• Have to perform any step besides checking out to
get a web site running
• Install/write setup data to the database
• Look at dbdeploy or Doctrine::Migrations
• Setup log ﬁles

your life
