VisualGDB started supporting unit tests in version 5.2. Having out-of-the-box support for CppUTest, GoogleTest and TinyEmbeddedTest, VisualGDB made it easy to check whether every separable component of your system works. However the size overhead and the necessity to create a separate test project makes it hard to use them for testing the behavior of the entire embedded system.
So in VisualGDB 5.3 Preview 7 we introduced a new mechanism called Embedded Integration Tests that does exactly that – lets you conveniently verify the behavior of your firmware without any significant overhead.
