what causes projects to go over budget? twitter: bphogan email: brianhogan at napcs.com

it’s not always the client’s fault. twitter: bphogan email: brianhogan at napcs.com

bad developer practices + bad management practices twitter: bphogan email: brianhogan at napcs.com

testing can be frustrating. twitter: bphogan email: brianhogan at napcs.com

it can be boring. twitter: bphogan email: brianhogan at napcs.com

it can make things take longer. twitter: bphogan email: brianhogan at napcs.com

and many managers think that programming is like assembly-line work. twitter: bphogan email: brianhogan at napcs.com

so we don’t do it, even though we know we should. twitter: bphogan email: brianhogan at napcs.com

then stuff breaks twitter: bphogan email: brianhogan at napcs.com

and people get mad. twitter: bphogan email: brianhogan at napcs.com

then people lose jobs. twitter: bphogan email: brianhogan at napcs.com

so what do you do? twitter: bphogan email: brianhogan at napcs.com

you make testing automated! twitter: bphogan email: brianhogan at napcs.com

we need to make testing fast and easy... twitter: bphogan email: brianhogan at napcs.com

and it needs to be part of the schedule. twitter: bphogan email: brianhogan at napcs.com

Feature: creating a new page in the wiki As an average anonymous user I want to create a page about Cucumber So that I can tell everyone how awesome it is. Scenario: Creating a new page and editing its content Given I go to "/Cucumber" Then I should see "Edit this page" When I click "Edit this page" And I fill in "body" with "Cucumber is the best way to test apps!" And I press "Save" Then I should see "Cucumber is the best way to test apps!" twitter: bphogan email: brianhogan at napcs.com

features, not requirements. twitter: bphogan email: brianhogan at napcs.com

features are value propositions. twitter: bphogan email: brianhogan at napcs.com

Feature: creating a new page in the wiki As an average anonymous user I want to create a page about Cucumber So that I can help people improve the quality of their sites with automated testing. twitter: bphogan email: brianhogan at napcs.com

Given Then When twitter: bphogan email: brianhogan at napcs.com

scenarios describe the feature in detail. twitter: bphogan email: brianhogan at napcs.com

Given setups, preconditions, prerequisites twitter: bphogan email: brianhogan at napcs.com

Given Scenario: Creating a new page and editing its content Given I go to "/Cucumber" twitter: bphogan email: brianhogan at napcs.com

When describe actions twitter: bphogan email: brianhogan at napcs.com

Then Then I should see "Cucumber is the best way to test apps!" twitter: bphogan email: brianhogan at napcs.com

this process helps you get the app designed. twitter: bphogan email: brianhogan at napcs.com

these stories can then be run against live code! twitter: bphogan email: brianhogan at napcs.com

step deﬁnitions use Ruby code and regular expressions to run stories. twitter: bphogan email: brianhogan at napcs.com

but you can run stories against any web-based application twitter: bphogan email: brianhogan at napcs.com
