+QB64-PE Testing Framework
+=========================
+
+QB64-PE features two separate testing frameworks, one for QB64-based tests
+(mainly for the compiler and language functionality), and one for C++-based
+tests (for `libqb`).
+
+QB64-based Tests
+----------------
+
+The QB64-based tests live in `./tests/compile_tests`. Each folder in that
+directory represents a different category of tests, and within each of those
+category folders are `*.bas` files. Accompanying each `*.bas` file is either an
+`*.output` or `*.err` file with the same base name as a coresponding `.bas`
+file.  For test with an `*.output`, the `*.output` file contains the text that
+the program compiled from the `*.bas` file should produce. For `*.err` tests,
+the `*.err` file contains the text of the error the QB64-PE compiler should
+produce when attempting to compile that code.
+
+Tests can also have an optional `*.flags` file. The contents of this file will
+be provide as command line arguments to QB64-PE when compiling the test source.
+
+These tests are run via the `./tests/compile_tests.sh` script. The script
+searches the `./tests/compile_tests` directory for any `*.bas` files, and then
+uses the provide QB64-PE compiler to test them.
+
+C++-based Tests
+---------------
+
+The C++-based testing lives in `./tests/c/`. The tests themselves exist as
+`.cpp` files that compile into individual programs (each has its own `main()`).
+The tests make use of `test.h` to run their tests and give proper output, and
+failure is reported via the exit code.
+
+The C++ tests are compiled using the `./tests/build.mk` make build logic. It's
+fairly straight forward, each test executable gets its own name and then its
+own combination of source/object files necessary to produce it. If you're
+testing functionality from `libqb`, then you need to link the proper object
+files into your test.  Additionally, any extra compiler flags can be defined
+individually for each test.
+
+`./tests/run_c_tests.sh` is a script that runs all of the C++ tests during the
+build. Internally it has a list of the names of all the test executables (to
+avoid having to use `make` to discover them). It expects the tests to have
+already been built via a `make build-tests` call, and runs the executables one
+at a time and checks their exit code for errors.
+
+QBasic Testcases
+----------------
+
+The QBasic testcases are a selection of QBasic programs that live in
+`./tests/qb64_testcases`. During the build process all of these programs are
+tested to verify that QB64-PE is still capable of compiling them with no
+errors. The behavior of the compiled programs is not verified.
