goals for this session
Goals For This Session
  • Attendees will gain a better understanding of how to apply modern software development techniques for UI testing in an effort to create more agile and resilient tests, as well as improve overall quality.
  • “Automated testing done right is Software Development”
    • Elfriede Dustin and Marcus Borch @ GTAC 2008
tools you will see today
Tools You Will See Today
  • SWAT
    • Simple Web Automation Toolkit
    • C# library for writing tests against a web UI
  • Fitnesse
    • Wiki based requirements test tool

Both are open source and can be used either

together or stand alone

  • What is wrong with the record\playback technique
  • Applying Acceptance Test Driven Design
  • Refactoring
  • Pair testing
  • Comparing new methods to record\playback
record playback technique weaknesses
Record-Playback Technique Weaknesses
  • Brittle
      • Easily broken when features change, even when the feature is not part of the test
  • Very hard to update without re-recording
  • Not Agile
      • Can only be done when code is complete
  • Only tests what you record and not what you expect
  • Requires cleanup post recording
  • Time consuming
  • Hard to read and understand
acceptance test driven design
Acceptance Test Driven Design
  • A way of writing software where the test is written before coding has commenced
  • Not just for testing below the UI
  • A passing test demonstrates satisfaction of requirements
  • Allows both positive and negative test case scenarios
atdd as part of ui development
ATDD as part of UI development
  • Test defines the user experience
  • Programmers can code the user interface to a prewritten test
  • Automated tests are written alongside the test cases and coding effort
  • Turns vertical slicing into completed automation
how to use atdd with the ui
How to use ATDD with the UI
  • Starts with well written conditions of satisfaction
  • Automation script is developed alongside test case creation
  • Consistent naming standards are key*
      • txb -> Textbox
      • btn -> Button
      • lbl -> Label

*if naming is wrong, can be easily updated

  • Once test is complete, developer can start running the test against code
  • Once test runs green, the story is complete
user story 1 login
User Story #1 : Login
  • As a user I want to provide my username and password to login
  • Conditions of Satisfaction
    • Login and password boxes are present
    • Title should read “M&C Life Insurance”
    • Valid login should lead to homepage
      • Example login: ctaylor/password
    • Homepage should read “Welcome”
applying atdd continued
Applying ATDD continued
  • Example User Story #1
    • Title should read “M&C Life Insurance”
      • Title means an H2
      • Text reads: “M&C Life Insurance”
    • Login and Password boxes are present
      • Two text boxes
      • Login - >txbLogin
      • Password -> txbPassword
      • Login button -> btnLogin

  • Conditions of Satisfaction (Test underneath)
    • -Test Setup (Open the browser and navigate)
  • |OpenBrowser|
  • |NavigateBrowser||
    • -Login and password boxes are present
    • |AssertElementExists|id|txbLogin|INPUT|
    • |AssertElementExists|id|txbPassword|INPUT|

-Title should read “M&C Life Insurance”

|AssertElementExists|innerHTML| M&C Life Insurance |H2|

-Valid Login should lead to homepage





  • Why refactor?
    • Less time to write automation
    • Less maintenance
    • Creates reusable code
    • Creates a domain specific language
  • What is refactoring?
    • For our purposes
      • Turn frequently used blocks of code into single line reusable entities
      • Use variables to make tests more robust
      • Creates an easily readable test by using English named functions
additional benefits of refactoring
Additional Benefits of Refactoring
  • Allows tests to be easily updated if core features change
    • If login changed for example, only one update needed
  • Allows those beginning to write tests to take advantage of previously created work
  • Makes tests much easier to read and debug
user story 2 view my name
User Story #2:View My Name
  • As a user, I want to be welcomed by my name after I login
  • Conditions of Satisfaction
    • My first and last name are correct
    • Title should read “Welcome ‘first name’ ‘last name’”
      • Example: “Welcome Chris Taylor”
a test refactored
A Test Refactored
  • Example:






|AssertElementExists|Expression|innerHTML:Welcome Chris Taylor|H1|

  • Becomes:

!define userName (ctaylor)

!define password (password)

!include .Macros.Login

|AssertElementExists|Expression|innerHTML:Welcome Chris Taylor|H1|


pair testing
Pair Testing
  • Benefits rival those of Pair Programming
      • (Yes, we did in fact just site Wikipedia)
  • Can be very effective for both writing automation and locating missing requirements
  • Two heads are always better than one
  • While automating you can also accomplish exploratory testing
  • Can replace manual testing phase with the creation of automation
