Testing Your PowerShell Scripts

LISA: Where systems engineering and operations professionals share real-world knowledge about designing, building, and maintaining the critical systems of our interconnected world.

The LISA conference has long served as the annual vendor-neutral meeting place for the wider system administration community. The LISA14 program recognized the overlap and differences between traditional and modern IT operations and engineering, and developed a highly-curated program around 5 key topics: Systems Engineering, Security, Culture, DevOps, and Monitoring/Metrics. The program included 22 half- and full-day training sessions; 10 workshops; and a conference program consisting of 50 invited talks, panels, refereed paper presentations, and mini-tutorials.

Description: 

Shell scripts that run a production environment are just as critical, if not more so, than the software that runs in production. Our responsibility as professionals is to ensure that our scripts work as advertised. In this tutorial, we'll learn how to use Pester, a testing tool for PowerShell, to ensure functionality of our shell scripts.

Who should attend: 

If you've ever spent far too many hours on the weekend or overnight troubleshooting some PowerShell script that went off the rails, you should attend this tutorial. If you write PowerShell scripts that are intended to run in a production environment, you should attend this tutorial. If you write PowerShell scripts, you should attend this tutorial.

Take back to work: 

Attendees will take back an understanding of testing terminology and patterns. Attendees will learn how to write PowerShell scripts and functions in a testable manner. They will also have gained a familiarity with Pester, a testing tool for PowerShell.

Topics include: 
  • Types of testing and testing tools.
  • Patterns for writing tests.
  • Designing PowerShell scripts and functions to be testable.
  • Using Pester, a testing framework for PowerShell.
