How do you run your unit tests? Compiler flags? Static libraries?

Question

I\'m just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the

Answer 1

I tend to favour static libs over dlls so most of my C++ code ends up in static libs anyway and, as you've found, they're as easy to test as dlls.

For code that builds into an exe I either have a separate test project which simply includes the source files that are under test and that are usually built into the exe OR I build a new static lib that contains most of the exe and test that in the same way that I test all of my other static libs. I find that I usually take the 'most code in a library' approach with new projects and the 'pull the source files from the exe project into the test project' approach when I'm retro fitting tests to existing applications.

I don't like your options 2 and 3 at all. Managing the build configurations for 2 is probably harder than having a separate test project that simply pulls in the sources it needs and including all of the tests into the exe as you suggest in 3 is just wrong ;)
