Testing in C++ is not easy, it requires a lot of boilerplate code, macro usage and/or understanding of complicated testing frameworks. But it doesn’t have to be like that. C++20 will enable us to reinvent the way we write tests. If taking a glance into the future of testing in C++ peaks your interest this session is for you.
In this case study we will address the difficulty of testing with C++ by implementing a new, fully functional, macro-free testing framework [1] from scratch with modern C++20 features.
The main goal will be to leverage modern C++ in order to make the following snippet compile and run: 1. int main() { 2. "hello world"_test = [] { // Running "hello world"…3. expect(12_i == fib(7)); // hello_world.cpp:3:FAILED [ 12 == 13 ] 4. }; // tests: 1 | 1 failed 5. } // asserts: 1 | 0 passed | 1 failed
The session will also focus on how to design modern testing facilities such as: * Sub/sections * Parameterized tests * Behaviour Driven Development (BDD)
At the end of this session the audience will have a better understanding of C++20 features such as: * New additions to lambdas * User Defined Literals (UDL) * Concepts * Source Location As well as how and where to apply them. Additionally, attendees will get familiar with a new, expressive way of testing with modern C++.
Let’s get ready to test all the things at ACCU 2020 and follow the Beyonce rule - "If you liked it then you should put a test on it".
