the lightest feature rich C++ single header testing framework
-------
-The **doctest** library is inspired by the ```unittest {}``` functionality of the **D** programming language and **Python**'s **docstrings** - tests can be considered a form of documentation and _should_ be able to reside near the production code which they test.
+The **doctest** library is inspired by the ```unittest {}``` functionality of the **D** programming language.
It is heavily influenced by [**Catch**](https://github.com/philsquared/Catch) which is currently the most popular, simple and user friendly alternative out there.
+The main differences are:
+
+A complete compiling example with a self-registering test and a test runner looks like this:
+
+```c++
+#define DOCTEST_CONFIG_IMPLEMENT_WITH_MAIN
+#include "doctest.h"
+
+int factorial(int number) { return number <= 1 ? number : factorial(number - 1) * number; }
+
+TEST_CASE("testing the factorial function") {
+ CHECK(factorial(1) == 1);
+ CHECK(factorial(2) == 2);
+ CHECK(factorial(10) == 3628800);
+}
+```

If the client wants to [**supply the ```main()``` function**](main.md) (either to set an option with some value from the code or to integrate the framework into his existing project codebase) then the **```DOCTEST_CONFIG_IMPLEMENT```** define should be used.
The next most important configuration option is **```DOCTEST_CONFIG_DISABLE```** - when defined globally in the whole project before the inclusion of the framework header - everything testing - related is removed from the binary - including most of the framework implementation and every test case written anywhere! This is one of the most unique features of **doctest**.

- **```DOCTEST_CONFIG_USE_IOSFWD```** - the library by default provides a forward declaration of ```std::ostream``` in order to support the ```operator<<``` [**stringification**](stringification.md) mechanism. This is forbidden by the standard (even though it works everywhere on all tested compilers). However if the user wishes to be 100% standards compliant - then this configuration option can be used to force the inclusion of ```<iosfwd>```. It should be defined everywhere before the framework header is included.
-- **```DOCTEST_CONFIG_WITH_LONG_LONG```** - by default the library includes support for stringifying ```long long``` only if the value of ```__cplusplus``` is atleast ```201103L``` (C++11) or if the compiler is MSVC 2003 or newer. Many compilers that don't fully support C++11 have it as an extension but it errors for GCC/Clang when the ```-std=c++98``` option is used and this cannot be detected with the preprocessor in any way. Use this configuration option if your compiler supports ```long long``` but doesn't yet support the full C++11 standard. It should be defined everywhere before the framework header is included.

-## main() entry point
+## The ```main()``` entry point
+The usual way of writing tests in C++ has always been into separate source files from the code they test that form an executable containing only tests. In that scenario the default ```main()``` provided by **doctest** is usually sufficient:
+
+```c++
+#define DOCTEST_CONFIG_IMPLEMENT_WITH_MAIN
+#include "doctest.h"
+```
+
+This should be done in exactly one source file and is even a good idea to do this in a separate file with nothing else in it.
+
+However if you need more control - want to set options with code to the execution context or want to integrate the framework in your production code - then the default ```main()``` just won't do the job. In that case use **```DOCTEST_CONFIG_IMPLEMENT```**.
+
+All the [**command line**](commandline.md) options can be set like this (flags cannot because it wouldn't make sense). Filters can only be appended - the user cannot remove a filter given from the command line with code.
+
+```c++
+#define DOCTEST_CONFIG_IMPLEMENT
+#include "doctest.h"
+
+int main(int argc, char** argv) {
+ doctest::Context context(argc, argv); // initialize
+
+ // overrides
+ context.addFilter("test-case-exclude", "*math*"); // exclude test cases with "math" in their name
+ context.setOption("no-breaks", true); // don't break in the debugger when assertions fail
+ context.setOption("abort-after", 5); // stop test execution after 5 failed assertions
+ context.setOption("sort", "name"); // sort the test cases by their name
+
+ int res = context.run(); // run
+
+ if(context.shouldExit()) // important - query flags (and --no-run) rely on the user doing this
+ return res;
+
+ // your program - if the testing framework is integrated in your production code
+
+ return res;
+}
+
+```
+
+#### dealing with shared objects (DLLs)
+
+When integrating the framework in production code which gets built as a shared object (dll) everything still works. Many shared objects and an executable can have tests in them and can even use different versions of the **doctest** framework.
+
+Check out [**this**](../../examples/dll_and_executable/) example which showcases how to call the tests in a shared object from the executable (and it also showcases that if a file with a test case is included both in the shared object and the executable then the test is registered in both places).
