+Testing and code review is the bottleneck for development; we get more pull
+requests than we can review and test on short notice. Please be patient and help out by testing
+other people's pull requests, and remember this is a security-critical project where any mistake might cost people
+lots of money.
+
+### Automated Testing
+
+Developers are strongly encouraged to write [unit tests](src/test/README.md) for new code, and to
+submit new unit tests for old code. Unit tests can be compiled and run
+(assuming they weren't disabled during the generation of the build system) with: `ctest`. Further details on running
+and extending unit tests can be found in [/src/test/README.md](/src/test/README.md).
+
+There are also [regression and integration tests](/test), written
+in Python.
+These tests can be run (if the [test dependencies](/test) are installed) with: `build/test/functional/test_runner.py`
+(assuming `build` is your build directory).
+
 The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS,
 and that unit/sanity tests are run automatically.

+Assuming the build directory is `build`,
+running `build/test/functional/test_runner.py` with the `--coverage` argument tracks which RPCs are
 called by the tests and prints a report of uncovered RPCs in the summary. This
 can be used (along with the `--extended` argument) to find out which RPCs we
 don't have test cases for.
