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)

    It's also very useful to get to grips with using some popular libraries. Some might be ones that you'll find yourself using everywhere (e.g. fmt, spdlog, catch2), and some that have more specific usage, but are good to try out and explore what C++ can do in a ridiculously easy-to-use manner (e.g. crow, Dear ImGui). Make some toy projects that use some of these and you'll learn a lot.

    Swap Boost Test for something better and more modern. The current industry standard is Catch2 and google test. There are much better documentation available on how to use those than the ancient and dying boost stuff.

    It's just a couple of versions behind actually, and the latest version was released 11 days ago, but if you absolutely need the latest version, and conan isn't working, your best option would be to manually compile it or use it from the github repo of catch2, and this should be very simple considering you're on Linux

    Conan or Vcpkg are probably the best way forward to begin with. Seriously, stop what you are doing and go try those out on something simpler first, e.g. A hello world using fmtfmt, or a unit test using catch2.

    For stuff like this which is very easy to test (very predefined input vs output), I highly suggest using some testing framework. Catch2 is great, but there is also doctest and good ole googletest. If you do this, it would also be a great intro to CI, where you do some plumbing on github or gitlab where every commit causes a build to happen on their servers and run through the unit tests, and if it passes it gets merged into master.

    The following questions that I have are platform and testing framework agnostic but in the interest of being precise, I have been trying to set up CMake so that it is able to run a simple "Catch2" unit test. I'm use CLion as my test runner to make life easy and everything is running on Ubuntu 18.04.

    Again, there is no standard testing suite so you would have to pick a third party library (that preferably integrates with your build system). Popular choices are the google test framework and catch2
