- 1 Intro
- 2 Mix Tests and Production Code With Doctest - Implementing and Using the Fastest Modern C++ Testing Framework
- 3 About me
- 4 The lightest feature-rich C++ single-header testing framework Inspired by the ability of compiled languages such as D/Rust Nim to write tests directly in the production code
- 5 This presentation
- 6 Single header with 2 parts
- 7 A complete example
- 8 Example output
- 9 What makes doctest different
- 10 All this makes writing tests in the production code feasible!
- 11 Other most notable features
- 12 Unique anonymous variables
- 13 Auto registration
- 14 Test Suites
- 15 Lets talk about warnings
- 16 Silencing warnings in the header
- 17 Warnings in user code?
- 18 The preprocessor
- 19 Embedding a pragma in a macro
- 20 Silencing warnings in macros
- 21 Subcase macro expansion
- 22 The main() entry point
- 23 Removing everything testing- related from the binary
- 24 Expression decomposition
- 25 Translating exceptions
- 26 The Lippincott function
- 27 Major C++ issue - compile times
- 28 Compile times - header cost
- 29 Compile times - implementation cost
- 30 doctest 11 asserts
- 31 Runtime performance
- 32 Mixing tests and production code
- 33 Tests in header-only libraries
- 34 Tests in compiled libraries Many binaries (shared objects and executables) can share the same test runner - a single test case registry
- 35 Getting the most out of the framework
- 36 Where most of the effort went • Familiarizing myself with testing and other frameworks
- 37 History of doctest
- 38 description(const char*) • test suite const char
