Software Testing

To begin our series on software testing, we direct you to an excellent blog post by Jon McBee (CLA, CLED, CTD, LabVIEW Champion, Certified ScrumMaster). Jon begins with a comparison of software unit testing to flossing one’s teeth. We will let you enjoy his analogy directly, though one data point is interesting. In a survey that has been conducted over the last few years and includes over 150 respondents, less than 10% state that they “often” or “always” test LabVIEW code with the NI Unit Test Framework (UTF) or another tool. When asked about conducting structured testing, the number rises to only 20%. Jon’s article is an outstanding review of effective methods for software testing that will inspire us all.

SOFTWARE TESTING: START HERE

This will guide you in your first steps to implement a software testing strategy

TEST STRATEGIES FOR PROJECT SUCCESS: FROM DQMH TO AF AND BEYOND

One of the huge benefits of the Delacor Queued Message Handler (DQMH) is that you get a DQMH Tester for free. How does this feature enable project success? How can you apply this to building testers for the Actor Framework (AF)? What other DQMH test design guidelines can you apply elsewhere? Discover how investing in test saves time and money and makes your life easier.

USING ASSERTIONS IN LV TO ENABLE FASTER DEBUGGING & INTEGRATION TSTING

Learn about a tool developed and reviewed collaboratively by a group of Certified LabVIEW Architects and LabVIEW Champions to build assertions in LabVIEW. You can use this software engineering technique to insert components into applications to enable quick and efficient debugging. The assertions are compiled outside the deployment code to avoid any impact on performance.

LESSONS LEARNED FROM HW DESIGN APPLIED TO SOFTWARE & TEST-DRIVEN DEV.

Explore the commonalities between hardware development and software development and learn how they lead to test-driven development (TDD), modeling, reference designs, and more.

ALL THE LATEST ON YOUR FAVORITE TOPIC: UNIT TEST

Yes, you must unit test your LabVIEW application. But what is a unit? And what are the tools? At this session, get an important recap of unit test, an introduction to 'new kid on the block' InstaCoverage, and an informative panel discussion from those who have saved time and dollars by committing to test. (Session includes 30 minute demo of InstaCoverage and 30 minute panel discussion)

VI ANALYZER: LESSONS FROM A LARGE PROJECT AND NEW FEATURES IN 2018

Learn how NI engineers effectively used VI Analyzer on a large test program to reduce defects and streamline code reviews. Get their best practices and hear the feedback they gave the VI Analyzer team. Also explore the improvements in VI Analyzer 2018, many of which were prompted by these engineers' feedback.

BLOG SERIES BY WIRESMITH TECHNOLOGY: UNIT TESTING

James McNally is an expert LabVIEW Architect (CLA, CLED) and is an Alliance Partner. Join him on an interesting journey through unit testing. He also includes information on an open source test tool called LabSpy

SAVE TIME, MONEY AND SANITY WITH UNIT TESTING

This NIWeek session by Fabiola De la Cueva is an excellent intro to the value of unit test and the various tools to do unit test. The Resources tab links to the Community page that includes the video and the demo videos.

PRACTICAL TEST STRATEGIES - COVER ALL YOUR BASES

Learn how to manage end-to-end product traceability through real-world examples. Review industry-standard processes to understand the difference between what you need to test, and time and money wasters, know when to engage your test organization, learn how to design for test, and get strategies to effectively manage test coverage throughout the product life cycle. Discover how these practices can help you streamline your processes and learn tips and tools that can increase your engineering quality and lower your anxiety over anything you may have missed. (Actual slide deck coming in June 2017 - see "Resources" tab for video)

I stumbled upon this article on software testing and found it to be a really useful source of information. Jon McBee makes an interesting comparison between software unit testing and flossing teeth - it's an analogy that definitely resonates with me!I was surprised to learn from the survey mentioned that less than 10% of respondents always test their LabVIEW code with a tool like NI Unit Test Framework.
