Unit testing InstallScript

Question

I've got a handful of functions in my InstallScript that are good candidates for unit tests. My project is a InstallScript MSI project. I found an article about how to unit test Custom Actions with custom ICEs, but the code I want to unit test isn't in a Custom Action, it is in the UI sequence.

Is there a way to unit test this kind of InstallScript code?

Answer 1

I would suggest the SprintfMsiLog() InstallScript function. It will write to the MSI log file, and so you can troubleshoot what's happening just as if it were an MSI standard action.

I hope I'm understanding what you mean by "unit test".
