FakeIt VS Catch

Compare FakeIt vs Catch and see what are their differences.


C++ mocking made easy. A simple yet very expressive, headers only library for c++ mocking. (by eranpeer)


A modern, C++-native, test framework for unit-tests, TDD and BDD - using C++14, C++17 and later (C++11 support is in v2.x branch, and C++03 on the Catch1.x branch) (by catchorg)

    Coming from googletest/googlemock, I found FakeIt to be a rabbit hole. In particular, I recall not being able to match const reference parameters or something strange like that -- the matcher values would dangle I think. Ah yes, this issue here: https://github.com/eranpeer/FakeIt/issues/108.

    Another possible issue would be the include(Catch) in your root cmakelists.txt . To include Catch there it must be part of your module path. Otherwise you have to include the path to that catch2 cmake file. Here is that file in their repository - https://github.com/catchorg/Catch2/blob/devel/extras/Catch.cmake . I recon that CMake doesn't know about this file since you call find_package(Catch2 REQUIRED) later in your subdirectory

    Looks good but currently at least REQUIRE (most likely all the other checks too but I didn't test that) fails to correctly evaluate some expressions, due to fundamental problems with macros. One example is described in this issue of the Catch2 repository.

    However, you can use a unit test framework like GoogleTest or Catch2 whic creates a main() function for you which allows you to run single functions, as long as they have been created through some preprocessor macros. Then you can use a VS Code test adapter like this or this which may let you run a single test by right clicking it directly in VS Code.

    Make sure you write unit tests, I use gtest but catch2 is also good.
