Using this identifier is equivalent to not having written any tests – they simply no longer exist. The other effects of this identifier are that asserts within the test case body are turned into no-ops, so even less code is parsed/compiled within these uninstantiated templates, and the test runner is almost entirely removed. There is no instantiation of the anonymous template and there is no test self-registration – the test code will not be present in the final binaries even in Debug. Static inline void ANONYMOUS(ANON_FUNC_)() #define DOCTEST_CONFIG_IMPLEMENT_WITH_MAIN It was released in 2016 and has been picking up in popularity ever since.Ī complete example with a self-registering test that compiles to an executable looks like this: He is the author of doctest – the fastest C++ unit testing framework.ĭoctest is a relatively new C++ testing framework but is by far the fastest both in terms of compile times (by orders of magnitude) and runtime compared to other feature-rich alternatives.
Obsessed about developer productivity most of his public talks have been about optimizing the compilation time of C++ programs and reloading code at runtime. Viktor is a huge fan of the Nim programming language and recently worked on adding support for hot code reloading at runtime in the compiler. Which C++ unit testing framework do you use? In this guest blog post, Viktor Kirilov shares how Doctest, a new C++ testing framework he contributes to, is better than others.
