1 The Basics of TDD
1 Write a Test
4 Test successfull
3 Write the Code
2 Test fails

2 FizzBuzz: Hands-on TDD for
Developers
Demo

5. 5
3 Testing Frameworks
# Type Tool name Comments
1 TDD Pester Module
2 TDD Jester Module,
Similar to Pester, but different syntax :-(
3 TDD PSTest Module,
makes use of the Nunit DLL
4 TDD PSUnit by Klaus
Graefensteiner
No module,
Test runner “PSUnit.Run.ps1”
5 TDD PSUnit by lidingshan Module
6 Lint ScriptCop Module
7 Web
Automation
Test_Run by James
McCaffrey
Demo on Win8.1 with IIS, MSIE, PS

6. 6
4 ??: Hands-on TDD for DevOps
and System Administrators :-)
Demo

7. 7
5 Coding Rules Checking
With ScriptCop by Start-Automating
Lint alike
Get-Module -Name FizzBuzz | Test-Module
Get-Command -Name Get-FizzBuzz | Test-Command
Test-Command -ScriptBlock { function MyFunction{} }
.. but you can't check external .PS1 files ?!
Demo

6 Web Application Testing
by Microsoft Internet Explorer (MSIE) only
with Test_Run by James McCaffrey
as alternative to Selenium
Demo on Win8.1 with IIS, MSIE, PS

7 Practical Tips
● Use community events for free TDD training
● Global Day of CodeRetreat
● Softwerkskammer, Meetup groups, Java User
Groups, .NET Developer Groups, IT conferences
like Froscon, PyCamp....
● Be open to change your programming language on
such events ( Java, JS, Python, C#,.. )
● Start at home
● Continue at office by a pilot project
● Teach and train yourself with collegues, at own
events
