This might not be quite directly related to wix, apologies if this is not the right list. There's the largest number of windows installer experts here and this might be useful to all custom action authors :)
I've been working on unit-testing our C++ custom actions. In the beginning I had a shim that simulated MSI functions, but once we got to the complex ones (MsiExecuteQuery), it became clear that that's not the way to go. Today I create a database on the fly and can call any MSI function. Wrapped into CPPUNIT this makes a complete MSI testing framework. It looks roughly like this: MsiOpenDatabase(temporary file, MSIDBOPEN_CREATEDIRECT); // create a new blank database MsiGetSummaryInformation(...) // get existing summary information MsiSummaryInfoSetProperty(...) // set new minimal summary information for msi to be happy (PID_REVNUMBER, PID_PAGECOUNT and PID_WORDCOUNT), repeat for each property MsiSummaryInfoPersist // persist the property information in the msi MsiDatabaseCommit // commit the changes to disk MsiOpenPackage(temporaryfilename, & handle) // reopen the database as a runtime package Now I have an MSIHANDLE that can be passed into MSI functions. To call MsiDoAction, I also import the CustomAction and Binary tables that have the declaration of my custom action and the custom action binary respectively. Works well for immediate CAs. The one thing I can't figure out is how to execute deferred CAs? I tried running the whole sequence via MsiDoAction, but it always fails in InstallInitialize with 0x80070643: Fatal error during installation. Any ideas?
