How to unit test non-exported class in UWP component (C++/WinRT)

I'm looking for some guidance on my strategy for unit testing UWP components.



I am developing a UWP component using the C++/WinRT projection. This component contains a helper class that manages communication with a Bluetooth device. I would like to write unit tests for that helper class (BthDevice) without exporting them to the UWP component's interface.



I started by following some guidelines for testing non-exported DLL classes. Specifically, I created a new UWP unit test project. I explicitly added my project's include directory, included BthDevice.h, and added the class' BthDevice.obj to the linker settings. I fought a few linker errors, and now it's falling over because I'm using precompiled headers in the UWP component. I've given up for now.



It feels like this should be a simple task, and that I'm going about it the wrong way. Any guidance is welcome! Thanks.

  • In my case, I'm trying to unit test an implementation type from a UWP Unit Test project. So, the implementation type is NOT implemented in the consuming project.

  • If you #include the implementation file into a compilation unit of your test project, then that implementation type is implemented in the consuming project. At least that appears to be a workable solution, although I never used the built-in testing framework.

Use pre created SQLite database for Android project in kotlin

0 I am trying to use an already existing sqLite database in my android app. I have verified that it is loaded into the project in the assets folder and I can browse it in DB browser when I open it directly from the project. This is the schema for the table I am trying to query CREATE TABLE "ACTIVITY_LIST_TBL" ( `_ID` INTEGER NOT NULL, `ACT_NAME` VARCHAR NOT NULL, `ACT_CODE` VARCHAR, `IS_ACTIVE` INTEGER DEFAULT -1, PRIMARY KEY(`_ID`) ) Below is the activity that creates the sqlite helper and then on a button click I execute a query on the ACTIVITY_LIST_TBL. When the query is executed this exception is thrown: android.database.sqlite.SQLiteException: no such table: ACTIVITY_LIST_TBL (code 1 SQLITE_ERROR): , while compiling: SELECT * FROM ACTIVITY_LIST_TBL class CalendarActivity : AppCompatActivity() { private var cursor:Cursor? = null override fun onCreate(savedInstanceState:Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.calendar_activity...
