+**doctest** is a new C++ testing framework but is by far the fastest both in compile times (by [**orders of magnitude**](doc/markdown/benchmarks.md)) and runtime compared to other feature-rich alternatives. It brings the ability of compiled languages such as [**D**](https://dlang.org/spec/unittest.html) / [**Rust**](https://doc.rust-lang.org/book/second-edition/ch11-00-testing.html) / [**Nim**](https://nim-lang.org/docs/unittest.html) to have tests written directly in the production code thanks to a fast, transparent and flexible test runner with a clean interface.

+
+The framework is and will stay free but needs your support to sustain its development. There are lots of <a href="doc/markdown/roadmap.md"><b>new features</b></a> and maintenance to do. If you work for a company using **doctest** or have the means to do so, please consider financial support. Monthly donations via Patreon and one-offs via PayPal.

+
+A complete example with a self-registering test that compiles to an executable looks like this:
+
+
+
+There are many C++ testing frameworks - [Catch](https://github.com/catchorg/Catch2), [Boost.Test](http://www.boost.org/doc/libs/1_64_0/libs/test/doc/html/index.html), [UnitTest++](https://github.com/unittest-cpp/unittest-cpp), [cpputest](https://github.com/cpputest/cpputest), [googletest](https://github.com/google/googletest) and many [other](https://en.wikipedia.org/wiki/List_of_unit_testing_frameworks#C.2B.2B).
+
+The **key** differences between it and other testing frameworks are that it is light and unintrusive:
+- Ultra light on compile times both in terms of [**including the header**](doc/markdown/benchmarks.md#cost-of-including-the-header) and writing [**thousands of asserts**](doc/markdown/benchmarks.md#cost-of-an-assertion-macro)
+- Doesn't produce any warnings even on the [**most aggressive**](scripts/cmake/common.cmake#L84) warning levels for **MSVC**/**GCC**/**Clang**
+- Offers a way to remove **everything** testing-related from the binary with the [**```DOCTEST_CONFIG_DISABLE```**](doc/markdown/configuration.md#doctest_config_disable) identifier
+- [**thread-safe**](doc/markdown/faq.md#is-doctest-thread-aware) - asserts (and logging) can be used from multiple threads spawned from a single test case - [**example**](examples/all_features/concurrency.cpp)
+- asserts can be used [**outside of a testing context**](doc/markdown/assertions.md#using-asserts-out-of-a-testing-context) - as a general purpose assert library - [**example**](examples/all_features/asserts_used_outside_of_tests.cpp)
+- Doesn't pollute the global namespace (everything is in namespace ```doctest```) and doesn't drag **any** headers with it
+- Very [**portable**](doc/markdown/features.md#extremely-portable) C++11 (use tag [**1.2.9**](https://github.com/onqtam/doctest/tree/1.2.9) for C++98) with over 180 different CI builds (static analysis, sanitizers...)
+- binaries (exe/dll) can use the test runner of another binary - so tests end up in a single registry - [**example**](examples/executable_dll_and_plugin/)
+
+
+
+This allows the framework to be used in more ways than any other - tests can be written directly in the production code!
+
+*Tests can be considered a form of documentation and should be able to reside near the production code which they test.*
+
+- This makes the barrier for writing tests **much lower** - you don't have to: **1)** make a separate source file **2)** include a bunch of stuff in it **3)** add it to the build system and **4)** add it to source control - You can just write the tests for a class or a piece of functionality at the bottom of its source file - or even header file!
+- Tests in the production code can be thought of as documentation or up-to-date comments - showing the use of APIs
+- Testing internals that are not exposed through the public API and headers is no longer a mind-bending exercise
+- [**Test-driven development**](https://en.wikipedia.org/wiki/Test-driven_development) in C++ has never been easier!
+
+The framework can be used like any other if you don't want/need to mix production code and tests - check out the [**features**](doc/markdown/features.md).
+
+**doctest** is modeled after [**Catch**](https://github.com/catchorg/Catch2) and some parts of the code have been taken directly - check out [**the differences**](doc/markdown/faq.md#how-is-doctest-different-from-catch).
+
+[This table](https://github.com/martinmoene/catch-lest-other-comparison) compares **doctest** / [**Catch**](https://github.com/catchorg/Catch2) / [**lest**](https://github.com/martinmoene/lest) which are all very similar.
+
+Checkout the [**CppCon 2017 talk**](https://cppcon2017.sched.com/event/BgsI/mix-tests-and-production-code-with-doctest-implementing-and-using-the-fastest-modern-c-testing-framework) on [**YouTube**](https://www.youtube.com/watch?v=eH1CxEC29l8) to get a better understanding of how the framework works and read about how to use it in [**the JetBrains article**](https://blog.jetbrains.com/rscpp/better-ways-testing-with-doctest/) - highlighting the unique aspects of the framework! On a short description on how to use the framework along production code you could refer to [**this GitHub issue**](https://github.com/onqtam/doctest/issues/252). There is also an [**older article**](https://accu.org/var/uploads/journals/Overload137.pdf) in the february edition of ACCU Overload 2017.

+Support the development of the project with donations! There is a list of planned features which are all important and big - see the [**roadmap**](doc/markdown/roadmap.md). I took a break from working in the industry to make open source software so every cent is a big deal.

+// The concept of subcases (sections in Catch) and expression decomposition are from there.
+// Some parts of the code are taken directly:
+// - stringification - the detection of "ostream& operator<<(ostream&, const T&)" and StringMaker<>
+// - the Approx() helper class for floating point comparison
