Is it possible to run tests against lib binary

[novocodev]

I have a project that uses polly to build a library for iOS and OSX, I have added unit tests via ctest which executes a class that uses GTest

I have one question, I have to add all the library source files to the runUnitTest exe definition.

e.g. I have added the following to my to level CMakeLists.txt

# Unit Tests

if(IOS)
    add_test(
            NAME SimpleTest COMMAND "${CMAKE_COMMAND}" -E echo "iOS testing ignored"
    )
else()
    add_executable(runUnitTests foo_unit_tests.cpp ${LIB_SOURCE_FILES} )
    target_link_libraries(runUnitTests PUBLIC GTest::main)

    enable_testing()

    add_test(NAME SimpleTest COMMAND runUnitTests)
endif()

Is there a way force the library to build and link to it rather than pull in all the library source to the unit tests?

My library is defined as

add_library(foo SHARED ${LIB_SOURCE_FILES})

I hoped it would build and link to the tests if I added:

target_link_libraries(runUnitTests PUBLIC foo)

But that caused the linker to fail when trying to find the foo library symbols used in the tests.

For Unit Tests accessing private library functions makes sense so pulling in the lib source is maybe not so bad.

I would still be interested to know if there are alternatives to just adding the lib source to the unit test executable.

So in fact we are talking about OSX only according to the configuration I see.

That is something strange. This is a usual way to work.
