I'm looking at recommending a Unit Testing tool at our workplace for LabVIEW code. The majority of the code will be OO-based with relatively simple APIs. There are appear to be three options: UTF from NI. This has the integration into the IDE, test vectors, code coverage. We also have a license to use it. Unfortunately it also seems quite slow (second or more per test case). My main concern is that the tests will take too long to run under our larger projects (we will have hundreds or more cases), meaning they won't be run frequently. This goes against the common thought that unit tests should be quick to execute. VI Tester from JKI. This custom framework does support management of cases and suites but also requires test customisation and does not provide any mechanism for analysing coverage. It also appears to not be updated to support LabVIEW 2012 and 2013 and thus has a few gotchas (eg. incorrect template copying). Roll our own. Not the best solution with the obvious down-sides. What are the community's thoughts on this? Are there more alternatives?

I really think given NI's support, it would make a lot of sense to stick with what they have available. Rolling your own sounds like a big undertaking and while I really enjoy owning my own tools, the time and effort needed in building, deploying and supporting them just doesn't seem like a good idea. Especially on a thing that involves testing code components. Sorry to hear the NI solution is slow but because you have a license you should be able to get some support from NI to investigate this, or at least get some feedback from them. JKI's timing for their VI Tester was unfortunate. I felt bad for them when I heard the Unit Test Framework was coming out in what felt like a few months after the JKI one. As a result I get the feeling JKI is focusing their attention on other tools that they have a competitive advantage with.
