Introduction Earlier this year I started a project to design and build a control board.  Whilst waiting for a prototype PCB to be manufactured and for the result of a roadtest application to be announced, I started looking at LabVIEW NXG with the intention of automating testing of that board.  Undertaking the characterisation of 16-bit ADCs and DACs with 65,536 possible values each and coordinating with I2C signals from an Arduino, by hand, didn't appeal (funny that!) jancumps has prod ...
Introduction In this post, Post 1, I reviewed LabVIEW NXG and want to carry on the series by describing a framework I have created to simplify the creation of test applications and the interaction with test instruments.  In Post 1 I went through the process of creating a very simple application to obtain a test instrument's identity using the NI VISA components; as I started to create some applications to get to grips with LabVIEW NXG it became very clear that I was duplicating code, and co ...
Introduction In this post, Post 2, I describe an instrument testing framework.  Whilst creating that framework, I wanted to be able to unit test (regression test) parts of it as I progressed - there was a degree of complexity that I needed to ensure didn't break as I progressed the build.  This led me to being diverted for a period of time creating some Unit Tests and eventually abstracting that out into a Unit Test Framework.   This framework is no JUnit equivalent but quite del ...
