Unit Testing Intro

Corona Virus Update

Due to the corona virus, we are offering this workshop over Zoom. The Zoom version consists of 2 sessions. This provides the added benefit of giving students more time to absorb the material and ​the ability to practice with the material in between sessions so they can ask better questions. We are now contemplating bringing back in person workshops. We don’t have anything scheduled at the moment. If you are interested in scheduling a workshop either in person or over Zoom, let us know via email at sam(@)sasworkshops.com and we can set something up.


We want to bring the benefits of Unit Testing to the LabVIEW masses. Every developer deserves to have the confidence of knowing that the code they wrote does what they intended. They also deserve the ability to make changes to one part of their code without worrying about breaking something else. Unit Testing gives us that and much more.

Most programming languages view Unit Testing as an integral component to software development. We think the LabVIEW Community should do the same. The key to that is introducing developers to the concept of unit testing as early as possible. NI training does not mention Unit Testing until the more advanced courses, so we want to fill that gap.


This workshop is a 3-hour workshop presented over Zoom. The goal is to present Unit Testing to LabVIEW beginners and make it more accessible. We use a very basic LabVIEW Unit Testing Framework that requires no special skill beyond LabVIEW Core 1. We also teach a very simple yet powerful technique called the Humble Object to help test hard to test and legacy code. There are 2 exercises on writing unit tests and 1 exercise on refactoring hard to test legacy code into testable chunks to help you get some hands-on practice.

What is the difference between this and the full workshop?
